October 2012 IceBridge Antarctica resumes … Mission goal…monitoring the polar regions…Mission target… determine changes in ice cover and thickness, refine models for future sea level rise…Mission instruments…airborne geophysics. Good luck team.
The crews have spent the last few weeks in Palmdale, where the DC8 is based, for instrument installation and test flights prior to our move down to Punta Arenas, our home base for IceBridge Antarctica.
Instrument Run Down: We are flying with the same instrument suite as last year allowing us to see above, below and through the ice. Laser altimetry, for surface ice measurements, measured by the NASA Airborne Topographic Mapper, visible band photography, to allow for draped imagery, from NASA’s DMS (Digital Mapping System), three radar systems from Cresis to measure the ice thickness, composition and bed imagery (MCoRDS, Snow and KU band) and gravity to refine what is under the ice with Lamont using Sander Geophysics’ AIRGrav gravimeter.
ATM and the gravimeter both require GPS base stations on the ground throughout the deployment. Combined with the GPS receivers on the plane these allow very precise positioning of the aircraft, and the sensors on board, which is critical to all the measurements we make. Setting up the GPS stations is one of the first jobs in Punta Arenas.
Our First Mission for 2012 is Thwaites Glacier – Going Straight to the Heart of the Changes. On our way out of Punta Arenas, out past the airport, I noticed this feature in the landscape:
It appears to be the paleo-shoreline from the last interglacial (~80,000 yr BP), when sea level was higher than present. The very flat terrain results in any sea level change causing a large shoreline retreat. Evidence like this of changing shorelines, is one method scientists use to determine past sea level under a different climate. As we study different areas around the world, we must account for the local changes in how the land has risen or fallen. Changes in sea level can be a combination of an adjusted world/ocean wide (eustatic) sea level and the more local response from the rebounding (isostatic ) of the land that was previously depressed under a glacier as local ice is unloaded during deglaciation. Here the history of the shoreline was governed by a combination of changes in eustatic sea level and the isostatic response to deglaciation of the local ice load (De Muro et al. 2012). Putting together information from around the world we eventually build up a picture of the global changes that have occurred in sea level. Changes in sea level are directly connected to our work monitoring polar ice.
When we fly over the ice, we are monitoring how the ice sheets are changing at present, and learning how to understand the complicated interactions between the atmosphere, the ocean and the ice. Studying this helps us to understand which ice bodies are most likely to contribute to sea level, how quickly they changed in the past, and how quickly they might change in the future. It’s good to get this reminder as we head out on our first flight – especially as it is to survey the area where the glacier switches from being frozen to the land below [the bed] to where it goes afloat, called the ‘grounding line’.
Our first flight of the season will be along the Thwaites Glacier. Thwaites and Pine Island Glacier are two ‘glaciers of interest’, both large outlet glaciers that serve as conduits out of the ice mass of the West Antarctic Ice Sheet (WAIS), moving ice off the land into the surrounding ocean, and long considered its Achilles heel. Thwaites glacier has a very wide region of fast ice flow over its grounding line, and a relatively small change in that width has the potential to greatly increase the flux of ice into the ocean. Through the radar and gravity measurements collected on previous IceBridge missions we have been able to get a sense of the bed shape tipping downward as you move inland from the ice edge, and where pockets of water lie under the icesheet. Our goal today is to collect enough data to develop a more complete image of what lies under the ice in this area.
2009 Operation IceBridge surveyed a grid in front of Thwaites grounding line and identified a ridge in the rock of the sea floor. In the last few months a large section of Thwaites glacial tongue broke off just seaward of that ridge. This mission will fly back and forth along nine lines parallel to the grounding line of Thwaites glacier. In combination with flights from previous years, this will give us a map of the grounding zone at 2.5 km spacing.
We are hoping to learn more about goes on underneath this icy reach of the Earth each time we take flight.
I’m back in Bangladesh for the fourth time in the last two years, my eighth trip overall. It is the first time I’ve been here in October. It is about 90° and sunny. The monsoon is over, but water levels are still high. I have come to install more GPS around the country. With me is Sarah Doelger, an engineer from UNAVCO, an organization that provides technical support for research involving GPS. A number of out GPS stations in Bangladesh are systems on loan from UNAVCO. She has come along because we are establishing stations in remote areas and will use the cell phone system to call the receivers and download the data. I am also traveling around with Humayun Akhter, my partner for many years from Dhaka University, who keeps our network running, and his student Fayazul Kabir. The four of us will be traveling around the country by van and boat to install the stations to monitor tectonics and land subsidence.
As usual, we arrived at 4 AM after a full day or traveling and had to hit the ground running. After a short rest and shower at our hotel, we spent the day unpacking, preparing the equipment and buying the last few items.
Yesterday, was our first installation. We drove east to Comilla University sitting on the last exposed hill of the foldbelt. At a little over 100 ft high, it may not seem like much, but it stands out in a country where half the land is less than 10 ft above sea level. Thanks to bad traffic, it took 4 hours to get there, including a stop for breakfast on an island in the Meghna River. We met with the registrar over tea and cookies, then finally got to work about noon. This site fills a gap in our coverage of the Burma Arc foldbelt, a continuation of the same plate boundary as Sumatra, site of the 2004 M9.3 earthquake and tsunami. Here, the subduction zone is colliding with the largest delta in the world, folding the sediments into a broad set of folds.
Our GPS is measuring the rate of shortening of the foldbelt as strain builds up, possibly towards an earthquake. The antenna was attached to a 2-ft steel rod we cement into the roof of a reinforced-concrete University building. This is our preferred method for a country with almost no solid rock. The receiver, electronics and backup battery were installed in the control room of the large solar panel array just below the antenna. The only hiccup was tapping into their electric system for power and meshing their 2 wire system to our 3 wire system. Their system is not grounded, as we discovered when Sarah got shocked connecting our battery. He fingers have stopped tingling. It took a while to understand what we wanted and in the end we had to ground our system into the lightning protection grounding that we set up. It was all done in about 3 hours and stopped for a well-deserved lunch at about 4 PM on the way home, further hampered by traffic jams.
This morning we packed all our stuff in a large van and are working our way through the traffic to get to SW Bangladesh for the next 3 stations. I am really looking forward to getting out of the city and its traffic and into the calmer countryside.

My feet are soaking wet and I’m playing a game of Marco Polo, but I’m nowhere near a pool. It’s my second day on the job. It’s my second week of college. I have no idea what to expect.
I’m a first year undergraduate student at Columbia University, and I just began to work at the Tree Ring Lab at the Lamont-Doherty Earth Observatory after being told by a few upperclassmen that the Lamont campus “just isn’t for freshmen”.
On Friday, September 21st, several members of the lab headed to New Paltz, NY to do some field sampling for a project aiming to uncover particularly major ecological events in the Eastern United States in the past three hundred years. I had just started to understand the basic concepts of differing tree rings. When I was told we’d be coring trees and identifying them, I smiled and nodded my head enthusiastically. You should see my poker face.
We get to the town of New Paltz and drive right through the center, heading towards Minnewaska State Park.
After a deceivingly easy one mile hike on road-like paths, we get to the entrance point for the plot that was pre-designated Jackie, Dario, and Neil earlier in the spring. From that point on, I get to witness the transition from a suburban hike to what seems to be the set of Jurassic Park. We’re heading into the area surrounding a ravine, and my feet remind me that I’m not wearing waterproof boots. At some points I feel like I’m in a maze, and I start yelling MARCO! At that point I start remembering that I took the job because I wanted some hands-on experience in the field of environmental science. Grabbing the four-foot fern in front of me, I feel that I’ve made the right choice.
After some strolling, climbing and maneuvering, we finally reach the plot. Here I finally get to see what the overall project is really about.
While some forest ecosystems in the Western United States recycle nutrients and move through successional cycles at fairly large scales through natural and necessary fires, these processes are much slower and do not seem to occur at larger scales in the temperate forests of the Northeast. Trees experiencing suppressed growth only receive the necessary sunlight, water, and nutrients to experience quicker growth when surrounding competing trees perish, either through logging, disease, windstorms, or similar ecological processes. One can see this change as a drastic change in the width of tree rings: once a previously suppressed tree becomes dominant, the increased growth results in relatively wider tree rings.
When this drastic change is seen not only in the rings of one or two trees but across an entire forest ecosystem, a major ecological event is likely the cause. This project is aiming to find the causes of a few suspected major ecological events in the Eastern United States.
In New Paltz in particular, this project encountered a roadblock- some people believed our study forest in Minnewaska State Park was an old-growth forest, but so far the samples brought back have found evidence of logging in the late 1800s. The first samplings, using plots with a radius of 20 meters, returned few older trees that would be useful to the project. The radius was thus increased to 30 meters, and only trees with diameter greater than 40cm were cored past the 20 meter mark. After this adjustment, the second sampling returned double the amount of older trees. The real science can begin.
So here I am, learning all of this for the first time, and I’m fascinated. Another new student and I learn to core a tree, and we realize how physically strenuous it is, laughing about having to lift weights to get in shape for future fieldwork. Like that’s ever going to happen. We’re introduced to a few different tree species during the process, and we begin to learn how to identify them. For the past few days I’ve walked around trying to identify every tree in Morningside Park.
At the end of the day, I’m feeling pretty fulfilled. The way back to the trail isn’t as cinematic as my entrance through Jurassic Park, but I still feel like I won’t get up after sitting down in the car.
That night, I got a rare chance to talk to my cousin, a botanist in Cuba. I told him about my day and he told me that if I start beginning to enjoy science, and the general act of finding answers to questions others might not have thought of asking, it becomes an obsession. He told me I wouldn’t be able to get away from it. I think I’m starting to get a sense of that. I was hoping to land a job at the LDEO that would just let me begin to get my feet wet in environmental science. So far they’ve gotten soaked, but I have a feeling I’ve only started to dip my feet in the water.
This is the first in a series of guest posts by Ana Gonzalez, a first-year environmental science and creative writing student at Columbia University. Ana is a research assistant at the Tree Ring Laboratory of Lamont-Doherty Earth Observatory who will be blogging on the process of tree-ring analysis starting off with the joys of field work.
2012 is turning out to be an exceptional year in the eastern US. Starting out with what was essentially a #YearWithoutaWinter, followed by a heat wave in March, a hot summer, Macoun and Cortland apples coming in 2-3 weeks early, and the continuation of a severe drought in the Southern US that expanded into the Midwest and Northeast, this year’s climate doesn’t appear ‘normal’. From a 500-year perspective, this year’s drought in the northeast should actually feel like an exception for 58.2% of its people. While there have been droughts in the Northeast over the last 44 years, trees informed us that, as of 2011, we were living one of the wettest 43-year periods since 1531. It is shocking to see towns flood or covered bridges float away during tropical storms in the northeast. But, our new record suggests that the buildup of soil moisture prior to these storms might make these unusual[?] storms the norm.
Immediately preceding this epic pluvial (a period of increased precipitation) was the 1960s drought, one of the most intense droughts of the last 500 years. Having lived only during this epic pluvial, I cannot fathom this drought. Pluvial is my norm. So, every time I lead a hike or lab tour on campus, like during Lamont’s great Open House, I always ask if someone was alive during the 1960s drought. Heads tilt back, eyes come alive, and the stories pour out. People talk about tough times and odd events like a landfill catching on fire. I then congratulate them for surviving one of the worst droughts of the last 500 years. Then I have to say, “Uh, but it has been worse. Much worse.”
Often when looking deeper into Earth history, we see things that send shivers up our spine. For those who lived through the 1960s drought, our new record should send shivers up your spine. Our lab’s first study showed the 1960s drought to be the worst since 1700. However, when looking back almost another 200 years, we can say things like, “Yeah, the 1960s drought was bad, but it was only six years in duration.” [six years of below average conditions in our new record] Six years of drought is tough. It must have felt like a decade. But, how might we feel about 23 years of drought? How might a 23-year drought feel when the preceding 11 years had only a few years of average to above average precipitation? [shivers].
The current epic pluvial caps a 150-year wetting trend for the Northeastern US. This trend, however, is not limited to the Northeast. Much of the entire Eastern US has become wetter over the last 150 years. Only the Deep South has trended towards drought over the last 20-30 years.
For more on the development of our new record and some of the implications of what we found, go here. The rest of this post focuses on the contribution of biodiversity and broadleaf species to the new record.
Biodiversity, Broadleaf Species, & Tree-ring Reconstructions in Humid Regions
An interesting result of our study was that the use of a greater number of species can improve a tree-ring based reconstruction (for more examples, see here, here, here, here). Reconstructions have been made using multiple species in humid regions like southeastern NY State since the beginning, so the use of multiple species in not groundbreaking. But, our initial analysis indicates that using 10 records drawn from 10 species outperforms the 10 best chronologies regardless of species (best is defined as the strongest correlation to the climate data used for reconstruction). It seems biodiversity is not only good for life, it can be good for reconstructions of past climate.
We are not exactly sure why increased diversity might improve reconstructions. My pet hypothesis is that each species has a different sensitivity to its environment and that by combining multiple species, differing responses are filtered out, resulting in a more accurate common signal. Some of this is driven by genetics. Some of it could be driven by the ecology of the sites where trees live. Think of it in human terms: some people can eat whatever they want and never gain weight. Some of us look at a banana split and gain two pounds. We might disagree on what we want for dessert, but when offered a fine blueberry pie, or for us sweet tooths – maple cream pie, we can generally agree if it is righteous. I imagine trees have a similar response.
“Remember 1972? Wow, that was a good water year!”
“ Yes, that was a good year, but I really liked 1989.”
“Oh yeah, that was a good year. But what about 1833?”
All 27 records chime in chorus, “Most righteous. Water. Ever!!”
These findings bode well as tree-ring scientists move into new regions of study – say the rich, temperate, broadleaf forests of Asia, for example. Regions with a vast array of tree species could be a boon for the future of dendroclimatology (the reconstruction of climate from tree rings).
Thinking about how we can improve reconstructions is important. Many scientists are exploring new statistical techniques to extract a chorus of solidarity from trees. From a biological perspective, though, the rate of extinction (literal and functional) is a real threat to our science. Hemlock woolly-adelgid is wiping out hemlock trees, a stalwart species and one of the backbones of the North American Drought Atlas. The loss of hemlock and other important species will thus diminish future reconstructions. Replacements species are needed.
Of the 12 species used in our study, eight are broadleaf species. We found that tuliptree or tulip-poplar (Liriodendron tulipifera) is one of the best species to replace hemlock*. Not only is it drought-sensitive, it has shown to be long-lived: a 512 years old specimen was recently found. Amazingly, only about half of its radius was recovered, as the tree was hollow. I would guess this species can live 600 to 700 years, if not more.
Our study also found other broadleaf species suitable for dendroclimatic research. These species include: black birch (for Yanques, but sweet birch for Southerners; Betula lenta), pignut and shagbark hickory (Carya glabra and Cary ovata, respectively), and northern red oak (Quercus rubra). While these trees do not live as long as hemlock or tulip, they are proving to live longer than expected. Continued exploration of species in the diverse eastern North American forest for maximum ages and climatic sensitivity should help dendroclimatological research as species are lost.
* Tuliptree is quickly becoming one of my favorite trees. It great longevity is a real treat. It is now the tallest documented tree in eastern North America now, too. But, it is how it handles drought that is so fun. Tuliptree is a drought-deciduous species, meaning that, during drought, it cannot close its stomata as well as other species to staunch the loss of water from its leaves. Therefore, it drops leaves to reduce water loss. If you paid attention to this tree in 2012, you would have noticed yellow leaves in July, a more common leaf color in September.
The really, really cool thing about this species, however, is that it also has indeterminate growth. This means that, unlike many temperate trees, its growth is not limited or set prior to the growing season. I once saw tuliptrees putting on new leaves in September following a dry August. This plasticity is awesome. It also suggests that September Song is not necessarily mournful for tuliptrees.
Every year, when the height of the dry season comes to northern Thailand, the air gets foul. The extent of the problem is dependent upon, among many factors, the weather and more specifically the temperature profile of the air. When a temperature inversion sets in, warm air aloft “caps” the cooler air that has descended into the valleys and prevents circulation (the normal state of the atmosphere is a lapse rate of decreasing temperature with altitude). As a result of an inversion, air pollution from cars, buses, burning, cooking, construction, etc., gets trapped in the valleys and basins and develops into an increasingly toxic brew. This doesn’t occur to extreme levels every year, but I have experienced it several times in Chiang Mai over the past decade, and this past season was pretty bad (see Thailand: pollution puts Chiang Mai off the tourist trail).
Photos of Chiangmai air pollution this past season: All pictures were taken at midday, no clouds, just smog.
The levels of fine particulates became very high, and this causes major respiratory problems for many people, the very young and very old in particular. But clearly it doesn’t do anybody any good. Because I am prone to bronchial infections, when the air got bad this year I suffered for weeks with a severe hacking cough that may have led to my herniated disk injury. In a wonderful twist of irony, I traveled to Bangkok, Saigon and Taipei to get cleaner air to help me overcome my illness. It worked too, but when I returned to Chiang Mai before my return home I began to deteriorate once again. (See my blog post, That Thousandth Cut, for the backstory.)
The costs of this problem are very high, due to major health problems for a large and poor population, and flight delays in the region due to poor visibility. Since it is a very specific set of conditions that leads to these inversion events, it would be important to explore the effects of regional temperature projections and how this might effect the occurrence and duration of future events. More importantly, are there ways to mitigate the effects of these inversions? Obviously, producing less fine particulates and reducing the primary pollution sources is paramount, but for that there needs to be the will at the highest of levels, and since the overall problem knows no borders, there isn’t the will. Much of the blame each year goes to the hill tribes who burn the surrounding mountainsides, but it seems that much of the source is more localized than that, and much of it is regional pollution that sits over the entire region. Whatever the source, however, something needs to be done. The problem is that when the rains come the awful air is cleared out, and with it any sense of urgency to act. It is then forgotten about until the next inversion comes a year later. This short-term memory does not help.
This from a Chiang Mai based website on the problem:
Air Pollution: Key facts from the World Health Organization
- Air pollution is a major environmental risk to health and is estimated to cause approximately 2 million premature deaths worldwide per year
- Exposure to air pollutants is largely beyond the control of individuals and requires action by public authorities at the national, regional and even international levels.
- The WHO Air quality guidelines represent the most widely agreed and up-to-date assessment of health effects of air pollution, recommending targets for air quality at which the health risks are significantly reduced.
- By reducing particulate matter (PM10) pollution from 70 to 20 micrograms per cubic metre, we can cut air quality related deaths by around 15%.
- By reducing air pollution levels, we can help countries reduce the global burden of disease from respiratory infections, heart disease, and lung cancer.
- The WHO guidelines provide interim targets for countries that still have very high levels of air pollution to encourage the gradual cutting down of emissions. These interim targets are: a maximum of three days a year with up to 150 micrograms of PM10 per cubic metre (for short term peaks of air pollution), and 70 micrograms per cubic metre for long term exposures to PM10.
More than half of the burden from air pollution on human health is borne by people in developing countries. In many cities, the average annual levels of PM10 (the main source of which is the burning of fossil fuels) exceed 70 micrograms per cubic metre. The guidelines say that, to prevent ill health, those levels should be lower than 20 micrograms per cubic metre.
Chiang Mai isn’t the only place that suffers from temperature inversions that create health hazards, and in fact it is a common problem for much of the basin and range country in the western USA. My colleagues at Utah State University suffer through an annual period of very poor air that gets trapped along the Wasatch Range every winter (see NOAA, National Weather Service Forecast Office, Salt Lake City, UT). Therefore I plan to avoid going to Logan in the dead of winter. Therefore I plan to avoid going to Logan in the dead of winter.
As bad as the problem is in Chiang Mai, it is even worse in other parts of Thailand, and across much of Southeast Asia. The link between anthropogenic pollution — inclusive of greenhouse gases — and a plethora of health issues ought to be at least as compelling a reason for us to cut emissions than the far more difficult to understand link to AGW (Anthropogenic Global Warming.)
As I have alluded to earlier, if people can see how these issues can impact them in more immediately pressing ways they are more likely to care about action. I always thought the AGW debate was too esoteric and too complicated to explain to a general population that is bombarded with too much information on a daily basis. Whereas the “hey, this stuff can kill you” message is one that just might get through. As for me, I plan to avoid these areas when the air gets like this, so my forays into Southeast Asia will try to avoid the February-March season, and for good measure April too because it is so bloody hot! I am lucky enough to have the freedom to choose my residence times. For most of Chiang Mai’s population they don’t have that luxury, and they just have to endure the best they can. In the meantime, if you travel to northern Thailand, Laos or Myanmar in February, you might want to bring your gas mask.
PALISADES, NEW YORK — My hands floated above my head, rotating in all directions, swaying weakly like reeds rustling in a gentle breeze. At least that was the image I held in my head, clouded as it was by the anesthesia. Between my hands I saw Orawan at the foot of the bed, staring at me with great relief in her face.
“Hey baby, how are you?” I asked almost a little too cheerfully, as I dropped my arms to the bed. ”Come here, give me a hug.” I was seriously groggy, and it was difficult to stay awake. I have memories of an alarm going off next to my head and a nurse urging me to breathe, happening more than once. I am not sure if that really happened or if it was imagined, but my memories from those few hours are hazy.
“Hey, go easy there.” Orawan chided as she took my hand. ”Try not to move too much.” I could sense the massive relief she was feeling, after waiting nearly 4 hours to see me after I left her standing in the hallway as they wheeled me into the theater.
The surgery was a success, or so I was informed. At least I could still move my arms, and I didn’t see a respirator anywhere in sight. I quickly checked for a colostomy bag and was relieved not to find one. I was still dopey enough that I couldn’t feel any pain yet (that would come in time), and the intense pain I had lived with for the past five weeks appeared to be gone, as the bits of ruptured disk had been removed from my spine, relieving the pressure on my C7 nerve head.
So, what happened? The week before I returned from Asia, on March 12, I awoke with a burning agony running down my left arm that would not desist. I didn’t know the extent of my injury until I had gotten home to New York and had an MRI, after a week of unrelenting pain in my left arm and under my scapula. It was a very uncomfortable flight across the Pacific back to New York, made tolerable only because of a class upgrade and lots and lots of drugs.
The MRI showed that I had clearly ruptured the disk between my C6 and C7 vertebrae, and surgery was pretty much the only option. Though I don’t remember it, I had told Dr. Quest that I loved him, emphasizing that it was not in any manner that should elicit his alarm, but love just the same. He took care of me as promised, and now that it was over I felt a massive sense of relief. Now, six weeks after surgery I am mostly recovered, with only minor pains and numbness as reminders of those terrible 5 weeks.
So what has this to do with climate change? Well it is the reason for my absence from this blog, since I couldn’t sit at my desk for more than 20 minutes at a time, and the reason for me barely accomplishing any work for more than a month. And now that I am recovering, I face a mountain of work the likes of which I have never seen, but never have I been so thankful for being able to work.
It had surely been a run of bad luck since my last entry, starting with the infection in my scalp from hitting that doorjamb in Chiang Mai, an infection that was not even cured when I developed a terrible bronchitis from the smoke and haze of Chiang Mai’s annual February foul air festival (a phenomenon that is related to climate change). After my return from Yunnan I went to Taipei for a week of lectures and meetings, and Taipei’s far cleaner air began healing my lungs, but I was still with a very deep cough that would often wrench me from sleep. I then went to Vietnam for a week for the opening of the International Center for Tropical Highlands Ecosystems Research, with even cleaner air in Dalat, and that just about finished off the bronchitis. But scarcely two days back in Chiang Mai, back in the horrible air, and I began to cough once again. It was then, on Monday the 12th of March that I awoke in such pain. The doctors believe that it may have been the pressure from coughing that served as the final straw in rupturing my disk, but in truth the injury was probably the result of a lifetime of accumulated injuries and strains, football, hockey, basketball, coring trees and carrying a backpack. It could have been any and all of those things.
So, I am back now, ready to catch up on a few entries I have wanted to write. I apologize to Lori for the long delay and I hope she can forgive me, and welcome me back. The way I see it things can only go up from here, now that Dr. Quest delivered that thousandth cut.
CHIANG MAI, THAILAND — The expression “death by a thousand cuts” refers to the practice in imperial China of killing someone by slicing them repeatedly, never very deep, until they die from their multiple, tiny wounds. I thought of this on Friday night when I hit my head on a door jam, cutting my scalp on the rock-solid, wooden edge. This happens to me frequently over here, since I am about 188 cm tall and the bathroom doors are always about 185 cm maximum. Just low enough that if I walk through upright I get a nice laceration on the top of my increasingly sparsely covered pate. I am pretty used to this by now, so aside from a momentary barrage of cursing, I didn’t think much more about it for the rest of the evening. However, the next morning, I awoke with a pain behind both ears and a bizarrely misshapen, triple-horned crest on the top of my head that was hot to the touch. Infection had occurred in about 5 hours. I went to Suan Dok Hospital the next day and the doctor said, “Yep, you have an abscess on your scalp, and the pain behind your ears is the swollen lymph nodes that drain the scalp.” He prescribed antibiotics and some wound dressings and told me to come see him next Saturday. After 3 days of medicine the infection is gone, and the swelling is down.
I have always heard how one needs to keep one’s wounds thoroughly cleansed in the tropics to stave off infection and sepsis, but I spend so much time here that I have gotten careless. I am reckless and clumsy, and I have had multiple wounds from a variety of things, and none has gotten infected to this stage. And it happened so rapidly that I was taken by surprise. Death by a thousand cuts.
I leave for Xishuangbanna in southern China on Sunday. I am going there to lecture at the Xishuangbanna Tropical Botanic Garden hosted by my colleague Dr. Fan Zexin. Fan was one of the participants at the PAGES Asia2k workshop we just held in Chiang Mai, having been a contributor of tree ring data from the upper reaches of the Mekong River in Yunnan province. We are planning a collaborative project on studying the rare and endangered conifer Taiwania cryptomerioides that can still be found in some isolated stands. These trees are quite huge and can attain great age, but have been seldom studied for tree ring analyses and have the potential for great value in the upper Mekong. They are also being cut at an alarming rate everywhere they are found, so we are on somewhat of a salvage mission. If we are to get into the areas of Yunnan where the trees are found, it might have to be in late August after the winter cold and the worst of the monsoon rains.
One thing about developing tree ring reconstructions of streamflow, it has been shown that temperature from the upper headwaters regions can be as important a factor as rainfall for predicting baseline streamflow because of the importance of meltwater in keeping up base flow (i.e., flow in the dry season in the case of the Mekong, rather than the sizeable contribution of the annual monsoon rainfall that contributes to peak flow). This work is part of the overall goals of my Greater Mekong Basin project, and will give us the very important record of how the Mekong streamflow may have varied back in key periods of the past millennia. I will send an update from Xishuangbanna when I am there, and try to include some good pictures of the place. I have never been there so I don’t know what to expect.
It has been pointed out to me more than once that I have a tendency to talk about food a lot in my blogs. With this in mind, I will be sure to report on the great meals I am bound to have in Yunnan, and send some pictures as well.
CHIANG MAI, THAILAND — There was one table available, just being vacated, and Orawan and I hurried to grab it. The place was filled with foreign visitors — Australians, Israelis, Americans and Dutch — and they were talking loudly, drinking beer and wine, clinking forks and spoons noisily on plates filled with hummus, tabouleh and falafel. We fought our way through the tight crowd and made it to the table before the previous diners plates had been cleared. Andrew and Piyawit were both running late. This was it, the very end of the PAGES Asia2k workshop for us, and Andrew was the last participant to leave Chiang Mai. It was an exhausting week for us, and now it was over, the dust beginning to settle on a meeting whose objectives were not entirely met. In the midst of the noise and confusion a hand touched my shoulder and I turned to see the owner of Jerusalem Falafel, Zahavit, with a perplexed look on her face.
“What are you trying to do to me?” she said, looking serious. I realized I was smiling at her, in anticipation of our usually warm greeting, so I quickly sobered my expression to match hers.
“Im sorry?” I said. I had no idea what she was talking about. I watched as Orawan secured our table and then I turned to face Zahavit and give her my full attention.
“Why did you bring an Afghani into my restaurant the other night?” she was clearly distraught. “Didn’t you read the news this week? In Bangkok they arrested Al Qaeda members sneaking explosives into Thailand and some of them got away. I nearly had a heart attack when I saw him, but then I realized he was with you.”
“Oh, you mean Usama!” I blurted out, and quickly realized that saying his name likely didn’t help matters. “He’s not Afghan, he’s Pakistani.”I offered, perhaps helping even less. “He’s a great kid, a PhD student from Karachi studying with a colleague of mine. Really, he is a very sweet young man, and very bright.”
“I know now he is okay.” She said, more relaxed. “But at the time I nearly fainted. You should have told me you were bringing him when you made the reservation!” She scolded, and slapped my shoulder lightly to emphasize her concern.
The truth is, it never occurred to me that Zahavit, an Israeli expat living in Thailand, married to a local Chiang Mai man, and running this hugely popular restaurant since 1991, might be alarmed at my bringing Usama to her restaurant. I hadn’t seen any news all week, as I had been too busy with the workshop, but I also hadn’t planned to invite people to dinner here until the end of the day, choosing to come here primarily because we had three vegetarians in tow, and the food has never disappointed us. Zahavit and her husband, Chiang, are very friendly and most gracious, their food is excellent and it is one of my very favorite restaurants in Chiang Mai. Funny enough, when I asked Usama to join us, it occurred to me to ask if it bothered him that the place was Israeli. He looked at me, puzzled, and replied, “If the food is good and it is vegetarian, why would I mind?” Fair enough, I thought, and that was the end of it. But I can only imagine the alarm felt by Zahavit, at the sight of a young Pakistani man, decked out in full local garb and sporting the thickest black beard I have ever seen, walk into her restaurant and take a seat. It has apparently never happened before.
“Usama Zafer Muhammed” I read his name out loud from the workshop participant list. He had joined me on the long teakwood bench outside of the conference room at the Ecole Francaise D’Extreme Orient, the beautiful location along the banks of the River Ping that was hosting our workshop (EFEO). It was during a coffee break, and Usama and I had been discussing the software I had just demonstrated that allows us to create point-by-point regression (PPR) reconstructions of climate from tree rings (while the folks who developed it were busy in another room attempting to reconstruct temperature over Asia — more on that in a minute), or other proxy sources that can be calibrated with climate data.
“Well, your name will almost surely cause you to be delayed at U.S. customs, but other than that I don’t believe you would have any problems”. Usama had asked me, with real concern on his face, if he would be in danger if he came to visit the U.S. The question really threw me, because as Americans we don’t think of our country as being unsafe to others, but it goes without saying that we all think of Pakistan as being a certain death for us to visit. Usama is a devout Muslim, and several times during the workshop he would go into a separate room to pray before returning to our group. He had told me earlier, when talking about sampling in the remote mountains of his country, that even he wasn’t safe in some areas because his religious and political views were far too moderate. However, he added, that if I were to travel with him to some of the areas where he is known, that I too would be safe, and in these other areas, we would both be in danger. I thought about it and realized that there are places in America that I don’t feel safe either, and places where I am pretty certain he might be hassled for being a Muslim. We surely have our share of violence and bigotry in America, though it is a very small minority that would engage in such behavior. Usama was making the point that it was the same in Pakistan, though the constant war and instability in that region, coupled with poverty and lack of real education for many, certainly exacerbate things.
In 2007 I had cancelled my trip to visit Usamas research institute in Karachi due to an attack at the airport in the hour before my plane was to leave Bangkok. Just as we were queuing at the gate, an announcement was made that the flight had been cancelled and they were putting us up at the Novotel for the night. In the ensuing confusion and while we all milled around at the gate the story came out that it was an act of terrorism in Karachi that was responsible for our cancellation. Early reports told of more than 40 people killed, and that the Karachi airport was unsafe. They would put us up for the night and see how things looked in the morning. Among the people on this flight were several Pakistanis, a few Australians, and one American marine on the security team at the Consulate in Karachi, and I had time to talk with many of them. The Pakistanis were all very sad to hear the news of the flight cancellation, and seemed distraught that I was now leaning toward not going. They seemed intent on convincing me that it was not as unsafe as I was hearing and that I should really go. I was headed there at the request of my colleague, Dr. Moinuddin Ahmed, to help him conduct a dendrochronology symposium and training session that was going to introduce tree ring analyses into their University system for the first time. It seemed quite exciting at the time I agreed, but now it seemed a little too exciting. I called Orawan from the airport and as soon as I told her what was happening she said, “I really don’t think you should go. Is it really worth the risk? I would feel better if you came back to Chiang Mai.” As far as I was concerned that was the last word, but I still was tempted to go until the marine took me aside, out of earshot of the others.
“How important is it for you to be in Karachi for this meeting?” he asked.
“Well, I promised my colleague that I would be there, I really ought to try.”
“Listen, you should know that the U.S. considers Karachi to be the most dangerous city for Americans in Asia, less safe even than Kabul and Baghdad. Dude, there is no green zone there and the Consulate is far from the airport. There’s nothing we can do for you if you get into trouble, so unless you absolutely have to go, I wouldn’t.” That was all he said, and that was all I needed to hear. The next morning they had resumed the flight to Karachi as the situation had stabilized, but I was on the first plane to Chiang Mai, to the great relief of my wife.
Usama presented his tree ring records from the high mountains of Pakistan, collected and processed over the past several years with Dr. Ahmed and other colleagues (see 500 years of Indus River flow modeling with tree rings), and he was here in Chiang Mai because he was among several other Asian researchers who were contributing their data to the overall PAGES Asia2k initiative that is charged with developing temperature reconstructions from Asia that ideally will cover the past 2 thousand years (hence, Asia2k). There are 2k initiatives for North and South America, Europe, Africa, Australia and even the Oceans. In all cases there are challenges of many kinds in producing the desired product (i.e., annual temperature — which will be used for the next AR5 model runs for the next IPCC assessment), but for Africa and Asia there are certainly greater obstacles than for other regions. Many of these difficulties are related to the fact that multiple, and often unstable, political entities comprise these continents, while many others are related to the culture of science in many of these countries where data sharing is simply not the norm. But one of the biggest obstacles is really that the proxy data are mostly precipitation sensitive more than they are temperature sensitive. As I have said previously, I believe that temperature (i.e., AGW related temperature) is only important because of its effects on the distribution of water on the planet, and it seems far more important to me that we understand the variability in precipitation around the globe, and to figure out how this might change in the future.
The director of my laboratory, Dr. Edward Cook, and I are both on the Asia2k committee, and at a meeting in Nagoya 2 years ago we worried how far behind our group was compared to others from the Americas, Australia and Europe, with regard to getting the necessary data from the research community. It was then that we hatched the idea (mainly it was Dr. Olga Solominas idea, and a great idea at that) to entice folks to submit their data in exchange for training in analyses that might speed up the process for some non-native English speakers to get their results published in top-tier international journals. The idea was to hold the meeting somewhere in Asia that was convenient for all participants, and not too expensive since our budget was quite limited. Since I was residing in Chiang Mai for several months each year, I offered to be a one-man local organizing committee (really two, to be fair, because of how much assistance I got from Orawan), and arranged to hold the meeting at the EFEO Chiang Mai center, just outside of Chiang Mais inner city wall and along the banks of the River Ping.
The meeting was three days long, and our primary objective was to use the newly contributed data (mostly tree rings, but some historical documentation-derived indices from Japan and China, some ice core data, and some lake sediment data as well) to produce a new temperature reconstruction from the Asian continent. Without going into too much detail here (stay tuned for that), we were not able to get a fully calibrated and verified reconstruction in the short time we had, and with the data set we ended up with, but we are a work in progress. There are a lot of difficulties associated with doing these kinds of reconstructions, not least of which is data quality control. At the end of the day, we are going to have about a 500-year temperature reconstruction for Asia, a far cry from the 2,000-year target, but better than a kebab skewer in the eye.
Usama grinned broadly and extended his hand to me and I shook it. He was genuinely grateful for the hospitality he was shown while in Chiang Mai, and his presence was one of the pleasant surprises for me. He and our Nepali participant, Narayan Gaire, were leaving the guesthouse together in a red sawng taew (the two-benched pickup trucks that are used in Chiang Mai as public transportation) to go to the airport. They had become good friends over the past few years having met at several regional workshops. These are fledgling dendrochronology programs in both of these countries, and it is remarkable to see the enthusiasm with which these two young men embrace learning this field of study. It will be because of the efforts of people like this that we are to have any chance of improving living standards across the globe, through education and engagement in the work the rest of us are doing — as equals and not perpetually as aid projects.
I was most impressed with these two fine young men, and I wished them both well on their journeys home. It saddens me terribly that our world is so unstable, and that we have the kinds of hatred that leads us to war with peoples in far flung lands, who have so little in material wealth, and yet strive to have the kind of enriched life that we take for granted. It is for that reason that I will think fondly of our little workshop, flawed as it was, and on my dinner with Usama, as a reminder of what is truly important.
CHIANG MAI, THAILAND — ”Rain never come in January.” Malee had overheard me predicting heavy rain for the night, as the black clouds swirled around the steep limestone cliffs at the base of Doi Luang. The clouds tore off in little wisps of vapor, black and menacing, and rose upward, obscuring the jagged, orange-stained, overhanging wall that was visible from Malee’s Nature Lover’s Bungalows in Chiang Dao. She brought 4 cups of home-roasted coffee, a basket of home made spring rolls, and two plates of coarsely cut French fries, stacked high, to the table and set these down in front of us.
“Not big rain, like you say now” she continued, “sometime small rain only.” She pronounced the word “small” as suh-mawn. As spelled in Thai based on its Sanskrit origins, words that end with the equivalent of the letter “L” are pronounced as we pronounce “N”, which is one of the more endearing things about Thai speaking English, to my ear.
Malee, always cheerful, has been a friend of ours for more than a decade. Orawan and I stumbled upon this amazing place in 1998 while looking for field sites. I was in search of the two Thai pine species that were reported to grow in the area, and we drove up the narrow road that dead-ended at an amazing cliff side Buddhist temple about 1 km past her rustic sign. At that time hers was the only guesthouse in this entire area, surrounded by empty fields and jungle, and local villagers foraged the nearby forests for bamboo, edible plants, and anything else of use. We stayed there one night and it seemed within hours we were friends, and we stayed with her numerous times until about 5 years ago when we stopped working in the region. Malee came to our wedding in Chiang Mai in October 2001, one month after the terrible 9/11 attacks. Coming back here now was like visiting family again after a long absence. In the years that have passed much has changed, and now there are guesthouses everywhere on this road, in the true Thai fashion of mimicking what has proven successful. But still, in spite of the oversupply of copycat businesses, Malee’s is an oasis of peace and quiet, and her business is very successful.
It is true that it is highly unusual for heavy rain to fall between December and April in northern Thailand, the months that comprise the driest part of the annual dry season. In the two decades that Malee has run her business, neither she nor any of her staff can remember heavy January rains like that which we were about to get. In most years it remains virtually rain free from late November until late April, when the heat reaches unbearable heights and the humidity boils up from the Gulf of Thailand. That is when the rains come, in May and June, not now.
The rhythm of the Asian Monsoon, as reliable as your own heartbeat, tracks the movement of the Intertropical Convergence Zone (ITCZ), which follows the migration of the sun’s most vertical ray from the Tropic of Capricorn in the Austral summer, to the Tropic of Cancer in Boreal summer — 23.5 degrees latitude in both hemispheres, respectively. This is the stuff of Physical Geography 101, and I can still hear the booming voice of the late Dr. Dow, my undergraduate advisor and mentor:
“The ITCZ moves north and south with the seasons, and this means… What?… Brendan! What does it mean when the ITCZ moves north to 23.5 degrees latitude?” The fear that accompanied students in Dr. Dow’s classes was ubiquitous across the room, particularly for those inclined not to pay attention. I thought of Dr. Dow now, and how I am glad that I was one of the students who actually did pay attention.
“I don’t know, Malee, it sure looks like heavy rain to me.” I said.
“Not possible” she replied, “it not rain in January”.
Hours later, as the rain pounded the metal roof of our bungalow with hellish force for two straight hours I thought about how one of the lessons of the prior week’s workshop in Chiang Mai applied to the anomalous weather we were experiencing today. Dr. Andrew Bell, a post-doctoral fellow working with me for the past year, presented work we have been doing for our Greater Mekong Basin project that uses our long tree ring records to inform climate predictions with extremely simple models that even small-scale farmers might be able to use. There are predictions made by local religious leaders from nearly all countries in Southeast Asia, for example in Thai from the Nung Seu Bee Mai Mueng “Book of the Northern New Year” which gives some kind of guidance to farmers. What Andrew has found is that these predictions have some degree of predictive skill simply because climate has a tendency to show persistence from one year to the next, and to statisticians this can be modeled as autocorrelation.
This feature of climate data is obvious when thinking about the seasonal shifts that we know well, for example, New York’s winter is cold, so there is a degree of correlation between January of one year and January of the next (i.e., both will be cold). The same is true for the dry season of Thailand — January will be dry in each year, hence the autocorrelation. The anomalous years, however, also tend towards persistence, such that if it is wetter or drier than usual (or colder or warmer, if you will) in a given season, the tendency to remain the same for the next year is slightly better odds than flipping a coin. So, if we assume persistence in the climate we can do a reasonably good job of predicting climate for the following season only. However, if we want to make informed 5-year or longer predictions, so that farmers might make more bold decisions about how and what to plant, and increase their profit margins, we need a better predictive tool than just guessing at persistence.
Andrew demonstrates that by using centuries or more of background data (e.g., long tree ring reconstructions of drought indices) one can do a pretty good job, far better than merely assuming persistence, at deciding what the next 5 years are going to be like, and the longer the record leading up to a given period, the better we do at predicting those next 5 years. The offshoot is more than just deciding what to plant, however. The real prize is in being able to use this information to give some form of blanket insurance to small-scale farmers, known as index insurance, which allows for coverage in case of drought or some other climate index value that is determined to be important. Interestingly, it is not the failure of the crops that is being insured, but the failure in the climate. Whether or not the climate adversely affects the crops is not relevant, as payout is made solely on the basis of climate. And by having lots and lots of small farmers buy into such a scheme, the greedy insurance companies can still make their profits and keep the costs low. For the GMB project, we are tasked with trying to find out how climate and its impacts can lead to conflict, what the parameters are for the conflict, and what factors are necessary to mitigate conflicts when they occur. We always believe that the past can help inform us of our present and our future, so using proxy records in these ways is done with this in mind.
The rain had ceased long enough for Orawan and me to walk out to meet our friends Paul and Anna, and their two children, Jonas and Amarita, who had gone out for a late lunch, and we joined them at the Chiang Dao Cave, about 2 km downhill from Malee’s. They sat out the rain in a small roadside restaurant, ordering food by pointing at things that looked appealing and hoping for good results. Paul and Anna are both seasoned travelers, and are no strangers to off-the-beaten-path locations, so they were enjoying their time in the village. We met them and strolled around the neighborhood, finding giant spiders and dead snakes, and an assortment of other horrible things the kids were fascinated with.
By the time we walked back to Malee’s it was near time for dinner, and the rain was beginning again. We had scarcely finished eating around 8:00 p.m. and walked back to our bungalow when the rain began in earnest. Broad sheets of water pounded the roof with a deafening roar until the morning light began to infiltrate our room. It was clear, that for today at least, the rains had come.
When it rains it pours. That phrase entered my mind, as I lay awake, eyes wide open, my wife breathing deeply beside me in the depths of slumber. Malee’s has always been one of the darkest places I have ever been at night, but on this night it was blacker than usual and I had a difficult time making out any features in the room through the impenetrable darkness. I had been having an inordinate number of interpersonal breakdowns with people lately, colleagues in particular, and I considered the notion that often things, negative things, come in groups or clusters, like rain falling. When it rains it pours. I agonized over the role I may have played, either indirectly or perhaps through callous indifference, in developing these rifts with other people, and I wonder sometimes about karma, and about biorhythms or other phenomenon that can lead to such things. Or maybe it is just the way of the world that sometimes we enter anomalous periods and lots of shit goes wrong. My Vietnamese friends tell me that my age, 53, is a very unlucky year, as is 49. I don’t remember much about 49, but in truth my 53rd year has been an outstanding year on many fronts. However, whatever is wrong with the cosmos lately that has me offside of so many people could be just a passing anomaly that will wash away, run off or be absorbed like the heavy January rains on the limestone flanks of Doi Luang.
PHNOM PENH, CAMBODIA — 2012 arrived in Phnom Penh with a splashy display of fireworks, and raging bands of celebrating Khmer youth who beckoned me to join their celebrations as I walked past them on my way back to my hotel. But conspicuously absent was the promised 2012 doom-and-end-of-the-world business that I was so looking forward to (although, it is still 2011 in the other half of the world, so I suppose there is time yet for Armageddon).
I had arrived in Phnom Penh just in time to join three fascinating women for dinner, Nancy Beavan and Sian Halcrow who I met in early 2010 when we worked together on a log coffin/jar burial site in southern Cambodia, and Kelly Fitzpatrick, the personal assistant to the Head of Administration for the Khmer Rouge Tribunal, whom I was meeting for the first time. Kelly was the PA to Andrew Cayly, the Co-Prosecutor for the Tribunal, before she recently switched jobs. Unfortunately I didn’t get to talk to her too much about her work, because it sounded truly fascinating. Nancy is an ex-Lamonter and a radiocarbon specialist who has been working and living in New Zealand for years, and is one of the more colorful people I have met in academia. By way of example, she worked for 8 days on the above-mentioned field trip to Phnom Pel with a rather obviously broken arm, and kept insisting “it really isn’t that bad, I don’t think it’s broken” while refusing to leave the field site early for treatment. However the moment I arrived at the field site I could see that her arm was broken, even after having been transported by taxi, rivercraft and motorcycle in the stifling, searing heat of the Cambodian lowlands, my brains still scrambled from the heat … the first words from my mouth were “How did you break your arm?”
Always cheerful and talkative, Nancy is a rare person with a remarkable path to academia and science. Among the more interesting aspects of her juvenile delinquency was running with motorcycle gangs, being a horse thief (okay, that sounds worse than it was!) and being an all around wild child before being brought into Columbia University under some sort of special program for at-risk youth, and that is how she ended up at Lamont-Doherty and met legendary Earth scientists like Wally Broecker and Lynn Sykes, among many others. She moved to New Zealand with her husband John Beavan, whom she met at Lamont, where she worked for years as a radiocarbon specialist before pursuing, rather later in life like me, her Ph.D. She is not one to shy away from controversy and a good scientific battle, a trait she attributes to her time with Wally and the other heavy hitters of the science world at Lamont. She is in the middle of a rather interesting row regarding the timing of the arrival of the first rats in New Zealand, and in true American fashion, exhibited little cultural sensitivity to the NZ scientific community’s consensus on such matters. I listened, riveted, to this story around a campfire in Cambodia, with rogue elephants crashing through the forest, and it was one of the highlights of this amazing trip which is captured by this wonderful radio piece by the freelance journalist and all-around nice guy, Brian Calvert, who joined us in Phnom Pel. The link is here. While you are at it, you might visit Brian’s website for some samples of his excellent writing, and truly ballsy journalism.
Sian Halcrow is a professor at Otago University in the lovely South Island city of Dunedin, New Zealand, and she spends much of her time each year working on archaeological sites in Thailand’s Isaan Province on the Cambodian border. Sian and Nancy have worked together for years, and have developed a really fun rapport that is great to be around. It was good fortune, therefore, that I was able to join them last night, since today Nancy is driving to the southern Cardamoms with a huge payload of food and supplies to be helicoptered into a new and very exciting jar site that they are just beginning to work on, and Sian seemed like some serious jetlag was coming on (she had just arrived from New Zealand).
Nancy just recently wrote a manuscript on the work so far on these coffins, based in large part on the series of Accelerator Mass Spectrometer (AMS) dates we managed from the little bits of wood I cut off the ends of each of the coffins. (When it makes it through the review process I will include more information, because it is quite fascinating). I tried to core the coffins with a micro-corer by crawling on my belly on narrow ledges, in the oppressively humid heat, where they were left by unknown people centuries ago (and I have the bat shit-impregnated clothing to prove it!) so I had to abandon that idea as it made the locals very nervous to think I might split the coffins in half. There is still much belief in ghosts and spirits in this part of the world, and they were not too happy with the possibility of pissing off the evil spirits! This continuing work in the Cardamoms is truly interesting, so I will try to keep things updated as the exciting bits begin to emerge. (For more on my attempt to core the coffins read, Race to the spice highlands: An expedition to Cardamom Mountains.)
After a long time without doing so, I finally logged onto my blog page the other day, and I saw there was a recent message from Paul B. who wrote in response to last year’s entry on Debating Global Warming: Lines in the sand.
“Believer?” “Denier?” These words are the realm of religion, not science.
Regarding AGW (anthropogenic global warming), I defy anyone to define the FALSIFIABLE HYPOTHESIS.
No one will. Because there isn’t one.
AGW is Lysenkoism at its finest: science-by-consensus … mob science.
The Consensus said Galileo was wrong. But The Consensus is a logical fallacy just waiting to happen.
Earth to REAL scientists … wake up!
First I want to thank Paul B. for getting me to look up Lysenkoism on Wikipedia, which describes, among other things:
Lysenkoism, or Lysenko-Michurinism, also denotes the biological inheritance principle which Trofim Lysenko subscribed to and which derive from theories of the heritability of acquired characteristics, a body of biological inheritance theory which departs from Mendelism and that Lysenko named “Michurinism”.
The word is derived from the centralized political control exercised over the fields of genetics and agriculture by the director of the Soviet Lenin All-Union Academy of Agricultural Sciences, Trofim Denisovich Lysenko and his followers, which began in the late 1920s and formally ended in 1964.
Lysenkoism is used colloquially to describe the manipulation or distortion of the scientific process as a way to reach a predetermined conclusion as dictated by an ideological bias, often related to social or political objectives.
Well, I admit I hadn’t heard of Lysenkoism, and I am thankful for the chance to add that to my increasingly overflowing brain storage area. As I interpret it, Paul B. is clearly implying that the side that is manipulating and distorting the facts is the one that claims there is a human component to warming temperatures (i.e., AGW — and incidentally, nice touch equating climate scientists and Leninism in the same sentence — well played, sir), and this manipulation was conducted for purely political reasons. To this end, presumably, there is no political reasoning on the other side of the debate — the side that states humans can’t possibly be influencing the climate, which is the view pushed by the energy sector and other industry-friendly groups — you know the groups with political reasons for pushing a no-AGW agenda. Hmmm … now, if only I could find a way to link them to Nazis …
To be totally fair, there is politics on both sides of any debate, and I thought I was clear that I believe that very thing in my Debating entry. I am not sure that Paul B. read carefully what I wrote, but be that as it may, I would like to think that, as scientists, we avoid “picking sides” of a debate and instead concentrate on doing the best analyses of data that we can do in order to prove or disprove hypotheses … when possible. I know that is not always true, of course, but in my experience I have met very few individuals, inclusive of the main Climategate players, who didn’t seem completely above board when it came to their science. We may have an informed opinion on the matter, but we ought to strive for letting the data speak for itself, and being able to admit when we were wrong. (Is it so wrong to gloat a little when we are proven right?) When someone questions an interpretation we make, it is an opportunity to look for corroboration or refutation of that interpretation. That is our job, in fact.
This was the idea behind the BEST project (please go to Berkeley Earth Surface Temperature for full details on this fascinating attempt to take the politics out of the AGW debate). This really was an independently funded initiative, and was in large part driven by Paul B.’s “deniers” including the much-vilified Koch Brothers and other industry friendly groups, who I can only imagine were hoping for an entirely different outcome from the one that emerged. The lead PI (principal investigator) was Dr. Richard Muller, himself quite skeptical of the AGW alarmists (another incendiary term — I plan to use a lot of those this year). In short the BEST study does not prove or disprove that AGW is real, but it does do something equally as important. It really does show that, some of the more embarrassing emails from some of our scientific community aside, that the climate scientists were not falsifying data as Paul B. and others would like us to believe, and there were more things correct than incorrect in the way data have been analyzed to this point (climate data in particular). In short, there is no sinister motivation in play by climate scientists to keep our highly lucrative jobs going.
The real story here then, with regard to BEST, is that there almost was no story. I am willing to bet that if a poll were taken in America that it would be a very small minority that has even heard of it, while that same poll with regard to Climategate (there I go, incendiary yet again!) would show a very high awareness, in direct proportion to the amount of media coverage they respectively received. Where did this story go?
I don’t mean to be disrespectful of Paul B. and others who have a viewpoint that I may or may not agree with. I for one actually do leave myself open to being convinced one way or the other on any matter. It is the tone of Paul B.’s message that I find objectionable. It isn’t debate, but just name-calling (though, admittedly creative name-calling) and does little to advance real answers to anything. It solidifies a base, nothing more. I wonder what Paul B. and others have to say about the BEST study? I welcome more comments on the matter, I really do.
And by the way, to all the Nazis, Commies, and other unsavory types out there, Happy New Year, and be safe and prosperous in 2012. I don’t believe our world will end this year, and that bias will color everything I do or say for the remainder of 2012. Lysenkoism, it seems, is alive and well.
CHIANG MAI, THAILAND — The Writer’s Club is a small bar and restaurant on Ratchadomneon Road in central Chiang Mai, and I sat facing the street, sipping contemplatively on a glass of the house red wine, inexpensive but surprisingly good. Orawan sat across the table from me, and we were discussing my inability to launch my first blog entry of the new season abroad, after my last entry about 9 months ago. I had been going on about this in my mind for the past few days, agonizing on what I was going to write, and how many other more important things I had to write first — a pre-proposal that is due in a week, 2 paper reviews and a review for an NSF proposal still not finished. It all bothered me, this pile of impending work, and yet I was having a difficult time getting stuck into any of it. Still, it nagged at me most that I hadn’t gotten around to writing a simple entry for this blog, just to jump start things for the new season. I realize it has to take a back seat to my real work, but I had promised Lori that I would have something written on the long flight across the Pacific. And here I was, empty-handed.
“I intended to have at least 2 entries by now.” I said, more to myself than to my glassy-eyed wife, who was becoming bored with my whining about my unfulfilled intentions. “Seriously, I have a plan. I will get this done.” I didn’t sound all that convincing.
“You know …” she began slowly, looking at the red wine that she twirled in her glass distractedly “that the road to hell is quite literally paved with such good intentions.” This last part dripped with no small amount of sarcasm. “No, really …” she continued, “I have it on good authority — the late Mrs. Buckley (God rest her soul) who told me as much.” My mother was fond of these kinds of expressions, and my own wife’s love of wordplay drew them to each other in the short time they had together before my mother’s passing. Orawan has been writing every day since we got here last week, short stories mostly for various Thai publications. Her diligence has impressed me, and quite frankly I thought she was being a bit smug about it now, in the face of my own losing battle with internal demons.
“Is that so?” I inquired with mock indignity. “Well I have it on equally good authority, the late Uthai Tong-Jeeeeeet (I said this last part exaggerating the way Orawan’s father would pronounce their family name, Tongjit, by drawing out the last syllable because in Thai the name ends with two “t” consonants — incorrectly so on his part, I should add) that Gum kee dee qua gum dot!” I sat back, satisfied that I had won this round of witty repartee.
“That doesn’t even make any sense.” She threw back at me. “I would rather have a handful of feces than a handful of flatulence? How is that relevant to this discussion?”
“I don’t know.” I mumbled, looking around now for some new distraction. “Hey look, Michael Vickery is here.” I got up and walked toward a shiny-pated, white mustached man sitting at the bar, drinking a glass of white wine.
Michael Vickery, the famous and colorful Southeast Asian and Khmer historian whose 1977 Ph.D. dissertation at Yale University was titled “Cambodia After Angkor, the Chronicular Evidence for the Fourteenth to Sixteenth Centuries”, is a long-time resident of Southeast Asia, most recently residing in Chiang Mai. He is a prolific writer of history, and still regularly visits his beloved Cambodia for months at a time, and in fact I met him a couple of years back at the EFEO in Siem Reap, where he and I were both keynote speakers at a workshop on the University of Sydney’s Greater Angkor Project. The beautiful thing about Michael, I discovered quickly enough, is that whatever is in his head usually comes out from his mouth, unfiltered. He can say the most wonderfully inappropriate things in mixed company, and usually of a prurient nature. Here is my chance, I thought, to get something juicy and politically incorrect that I can use in my blog.
“Michael Vickery, how are you doing?” I asked, extending my hand.
“I can’t see your face. Who is that?” came the reply, his hand shading his eyes as he squinted in my direction. It was already evening and the bar was dimly lit. I noticed that his large, Mr. Magoo-like glasses were sitting beside him on the bar, so of course he couldn’t see a thing. He wore his usual local garb, the loose-fitting cotton seua puen mueng that he sported exclusively. Michael is a regular visitor to the Writer’s Club and other Chiang Mai haunts, and he usually has some rather hysterically candid things to say about the “wannabe writers” who inhabit the place. As acerbic as he can sometimes seem, I have grown quite fond of the man, from the few meetings we have had, and the stories I hear from others who have met him. And he is really a brilliant mind with regard to the history of the region.
“Brendan Buckley,” I said.”It’s me, Brendan Buckley.”
“Oh yes, tree rings. How are your tree rings, Brendan Buckley?”
“They’re fine, Michael. My tree rings are all fine.”
We chatted for a few minutes, but he had to run off so I ended up with nothing juicy to quote from him. I returned to our table after but a few moments, slightly deflated, as our food came — a delicious Thai ginger soup and a few other dishes that we had ordered.
“Micheal is a pretty interesting guy,” I said to Orawan who was savoring the first spoonful of Tom Kaa Gai. “Maybe I can work him into my blog entry? I don’t know, like something about Angkor and climate change, something like that. What do you think?”
“I thought you planned to write about that BEST study from Berkeley that you were going on about the other day.” Orawan responded. “You kept saying how it was an independent vindication of the integrity of the climate scientists but hardly got a word of press, while the so-called Climategate business got covered to death and blah, blah blah… something about that. Weren’t you chomping at the bit to write about that?”
“Well, yes, I had intended to write about that but I couldn’t find the right title,” I offered weakly.
The truth is, that I have about 10 different subjects I want to write about, and the BEST study is surely there at the top. I have been trying to think about the angle I want to take on it, aside from just the obvious lack of attention it has gotten. I also plan to write about all the stuff I got up to this past spring and summer, including several conference presentations; a pilgrimage to what may arguably be the very birthplace of modern dendroclimatology as we know it, at Mesa Verde National Park; working with Utah State University scientists to reconstruct streamflow along the Wasatch Range; my 3 week backpacking trip with my brother, our childhood best friend and his early 20s son to the John Muir Trail in the Sierras, more than 3 decades after I had done it as an 18 year old; the proposals written and rejected over the summer; the trials and tribulations of a soft-money dendrochronologist. These are all things I intend to write about this season, along with covering the several trips I will be taking to Cambodia, Vietnam, China and Taiwan. I intend to write about all of these things, and I intend to write another proposal, even a paper or two, while I am here. Of course, it is a possibility that I may just be paving a few more kilometers of road on that journey to hell. That remains to be seen.
Brendan Buckley’s research on tree rings is creating a record of climate spanning 700 years.
Brendan is off to Asia again. If you missed last year’s adventures catch up with previous Tree Stories. While we wait for this year’s blogs, take a look at the images sent in by Brendan as he made his way to Asia.
It is a love-hate relationship I have with the National Science Foundation (NSF). I love them when they accept my grant proposals and I hate them when they don’t. In fairness, the majority of the time my proposals have been rejected (and it is the majority of my proposals that have been rejected) I can clearly see the reasoning behind it, because for the most part the system works as it is supposed to. As I noted before it is a competitive business, and some really brilliant people are competing against me, and this number increases every year (in direct proportion to my decreasing success rate). There are times when I have gotten reviews back that make me think the reviewers had no idea what they were talking about and I completely disagree with their assessments, and other times where I felt I was personally attacked. I have also been mystified when I got funded for a proposal I was convinced was not my best effort, so it really works both ways. Most of the time I feel the system is fair and I accept when I haven’t been good enough to make the grade. That is the nature of the beast that is the world of science funding and I am happy to play by the rules of the game.
Recently I had two perplexing exchanges with NSF. In the first instance, we got reviews back on a proposal I was included on (not as the lead principal investigator (PI)) that got the highest recommendation from the panel for funding. The peer reviews were mostly excellent and our proposal landed in the top 15 percent of the proposals based on the panel rankings. Then the program director, having decided to fund the top 20 percent of proposals in that batch, rejected ours from the chosen few, in spite of the recommendation of the panel to fund our proposal based on peer review. I am sure he had his reasons for doing so, but these weren’t explained to us in any way that I am aware of. If I had been lead PI, I would have been spitting fire, but the lead PI calmly allowed the issue to die a quiet death, which was the correct and adult decision (“live to fight another day” and all of that), though I would have at least asked for an explanation.
The second issue was more perplexing, involving a proposal that I am the lead PI on. In this case the program director decided not to even send our proposal out for review because we didn’t format the biosketch for one of my foreign co-PIs exactly right (we omitted a section heading). To be fair there are clear guidelines for such formatting, but we weren’t terribly far off from what is required. It seemed patently unfair to be rejected for a very minor infraction, and not at all in keeping with the spirit of the rules. I worked so hard to get this proposal submitted on time that I felt compelled to complain and lobby the program to reconsider. To my utter surprise they did reconsider (the squeaky wheel and all of that), and my proposal is now at the mercy of the peer review process, but at least it has a fighting chance to sink or swim on its merits. I believe that this is a really solid proposal, cutting edge even, and I would hate to see it not even get into the ring, as it were, regardless of its fate once it gets there. I think this example illustrates that the spirit of the review system is alive and well, when you can make your case on a matter such as this, and the very overtaxed “powers that be” at NSF can actually be persuaded. The love end of my relationship was, at least until the next rejection, restored.
One of the comments to my last entry regarding this matter was by another blogger, Eli Rabbet, who wrote:
As a hard money person who reviews soft money grants over the last 20 years I have noticed an increase in the number of proposals and a decrease in proposal quality as the soft money folk chip themselves up into smaller and smaller pieces (seriously 3 percent on one proposal). I have seen people chew themselves up as funding shrinks. Because you have to write more proposals, less time is spent doing science. I have remarked on this in my usual quiet way to a number of program managers.
Eli makes a good point, and I agree with him to a large extent. We do have to spread ourselves very thin, taking too few months per project and having to juggle several projects at a time, each with their own suite of administrative duties (and these duties increase in number every year). We spend less time “doing our science” than we would like to, and more time fulfilling an increasingly long list of administrative requirements attached to less money per project. But I still defend this system of science as perhaps the best terrible system we can come up with. If we received full support we might find the creative energy needed out of stark necessity, but few of us would complain about the increase in freedom to research without the constant anxiety about funding. As I said before, the system is by no means perfect. But it is the system we’ve got, and so far (knock wood) I have kept the lights on and the heat cranking.
More worrying to me than the system we are using, however, is the increasing anti-science clamor that is permeating our society. That is the biggest threat to getting good science results per dollar invested. We have always used our NSF to encourage the freest of thinking to take place. Instead of putting out strongly mission-driven calls for proposals, the NSF has always given miles of latitude for free thinking scientists to push the envelope of their respective fields. That is what put U.S. science at the forefront of global research, and it makes a compelling argument for increasing our commitment to science rather than decreasing it. Time will tell how far this trend continues, but we are all watching it closely. Soft money institutes like ours are finding it increasingly difficult to retain the brightest young scientists who understandably are going where the hard money is.
I have been terribly busy since my return from Asia two months ago, and this blog has been nearly mothballed during that time. But I have a few things I do want to write about, so for those who haven’t lost faith stay tuned.
