A piece of Halley's comet may have intercepted Earth's orbit in A.D. 536, cooling the planet with the dust it blasted into the atmosphere, says new research by Lamont-Doherty scientist Dallas Abbott.
A new study indicates that the supervolcano beneath Yellowstone National Park is far larger than scientists previously believed. Lamont-Doherty postdoctoral researcher David Ferguson explains what the findings mean.
Lamont-Doherty scientist Robin Bell will lead a U.S. team of researchers in mapping one of the least explored regions of Antarctica - the East Antarctic Ice Sheet's Recovery Catchment.
Lamont-Doherty researcher Nina Keul's work to measure changing ocean chemistry by analyzing the shells of tiny marine creatures known as pteropods is discussed.
The drought that has been afflicting most of the Western states for the past 13 years could be a multi-decade dry spell, says Lamont-Doherty scientist Edward Cook.
Tree Rings Reveal History of History-Changing Mexican Droughts - http://www.scientificamerican.com/article.cfm?id=tree-rings-reveal-mexican-drought-history
Lamont-Doherty scientist Richard Seager comments on a new tree-ring study linking prolonged droughts in Central America to the fall of the ancient Toltec and Aztec civilizations.
This week, we are launching a test of “IceTracker”—a tool that allows users to see the trajectories of Arctic sea ice forward or backward from any day between 1981 and 2012, as well as sea-ice speed, air temperature, water depth and the age of the sea ice.

The Marcus G. Langseth, a research vessel operated by Lamont-Doherty Earth Observatory, traverses the world’s oceans conducting marine seismic studies that contribute to new understanding of Earth systems. The ship typically spends half the year or more on research expeditions led by Lamont-Doherty scientists and colleagues from other research institutes. Mentions of cruises may conjure up [...]
Scientists from Columbia University’s Earth Institute will present important research results and special events at the Dec. 9-13 San Francisco meeting of the American Geophysical Union, the world’s largest gathering of earth and space scientists. Here is a guide in rough chronological order.
Four scientists and one PhD student from the International Research Institute for Climate and Society are attending the 2013 American Geophysical Union's Fall Meeting. Below are links to Q&As with each of the presenters and the schedule of their posters and presentations.
Work by Lamont-Doherty seismologists in 2012 that linked earthquakes in Ohio to underground wastewater injection wells cited.
Climate models! A bad pun becomes bright new way to talk about climate change.
Though average temperatures may slowly creep higher over the coming century, changes in some places may come faster than societies can adapt. Lamont's Jerry McManus comments on a new National Research Council Report.
"We really wanted to push the climate models pun and have them modeling," said Lamont's Rebecca Fowler. "We just felt like that would be a more effective means of communication, and they were all happy to do it."
A new study in Science attributes declines in mountain stream flow in the Pacific Northwest to a slowing of the westerly winds but Lamont's Richard Seager says the decline might also be due to greater evaporation.
Lamont-Doherty's permeable paving, which absorbs rainwater where it falls, cited.
The author measures her exposure to black carbon using a portable air-monitoring device developed by Lamont-Doherty environmental geochemist Steven Chillrud.
"I was realistic enough not to have unrealistic expectations," said Lamont's Klaus Jacob, the geophysicist who served on the city's climate panel and saw his own home flooded by Sandy. "Engineered measures such as sea walls, berms, levees, and raising of structures ... take many years if not decades to finance and implement."
What will New York City be like 400 years from now? That's the city we should plan for Lamont's Klaus Jacobs tells PBS Nova.
