Abrupt Climate Change

PI(s):

We all know that climate is either going to change, or is already doing so, as a result of human activities changing the atmosphere's composition and its land surface.

Study Adds New Clue to How Last Ice Age Ended

September 08, 2010

As the last ice age was ending, about 13,000 years ago, a final blast of cold hit Europe, and for a thousand years or more, it felt like the ice age had returned. But oddly, despite bitter cold winters in the north, Antarctica was heating up. For the two decades since ice core records revealed that Europe was cooling at the same time Antarctica was warming over this thousand-year period, scientists have looked for an explanation.
In Upstate New York, 42,225 Daily Temperature Readings, and Counting

May 06, 2010

Every day since Jan. 1, 1896, an observer has hiked up a grey outcrop of rock to a spot at The Mohonk Preserve, a resort and nature area some 90 miles north of New York City, to record daily temperature and other conditions there.
El Niño and a Pathogen Killed Costa Rican Toad, Study Finds

March 01, 2010

Scientists broadly agree that global warming may threaten the survival of many plant and animal species; but global warming did not kill the Monteverde golden toad, an often cited example of climate-triggered extinction, says a new study.
Glaciers Have Moved Together in Far-Flung Regions

September 23, 2009

A new study adds evidence that climate swings in Europe and North America during the last ice age were closely linked to changes in the tropics. The study, published this week in the journal Science, suggests that a prolonged cold spell...
Wallace Broecker Speaks to BBC's "The World"

July 30, 2009

Wallace Broecker Speaks to BBC's "The World", broadcast on July 7th & July 9th 2009 as part of a three part series on energy and climate.

As politicians and environmentalists prepare for the UN Climate Change talks in December to discuss urgent reduction of CO2 emissions, the BBC asked what is the future for global energy production?
Gas-Hydrate Deposits in Gulf of Mexico

July 02, 2009

U.S. scientists working on a research vessel in the Gulf of Mexico have made the most promising discovery so far of marine gas hydrate, a possible new energy source.

Potential Alternative Fuel, Usually Too Thinly Spread to Exploit
CO2 Higher Today Than Last 2.1 Million Years

June 18, 2009

Researchers have reconstructed atmospheric carbon dioxide levels over the past 2.1 million years in the sharpest detail yet, shedding new light on its role in the earth’s cycles of cooling and warming.
Fighting Global Warming by Turning CO2 into Stone

June 16, 2009

A power plant in Iceland is set to become the first in the world to try turning carbon dioxide emissions into solid minerals underground, starting this September.

In an $11 million pilot project, Reykjavik Energy will capture CO2 from its plant, dissolve the gas in water and inject it deep into volcanic basalt nearby. Over the nine-month study, some 2,000 tons of greenhouse gas will be treated.
Periodic Megadroughts Hit West Africa, Says Study

April 21, 2009

Global Warming Could Worsen Newly Seen Pattern

Researchers have developed the first year-by-year record of rainfall in sub-Saharan West Africa for the past 3,000 years, and identified a daunting pattern: a 30-to-60-year cycle of serious droughts that last a decade or more, punctuated by killer megadroughts that last for centuries.
Ecosystems Push South in Antarctica

Warming Climate Drives Plankton and Penguins Poleward

Adélie penguins are flocking closer to the South Pole. A new study in the leading journal Science explains why: they’re following the food supply, which is moving southward with changing climate.

6,000 Square Miles in U.S. Might Turn Emissions to Harmless Solids

To slow global warming, scientists are exploring ways to pull carbon dioxide from the air and safely lock it away.
Volcanoes Cool the Tropics, Say Researchers

January 06, 2009

But Global Warming May Have Helped Override Some Recent Eruptions

Climate researchers have shown that big volcanic eruptions over the past 450 years have temporarily cooled weather in the tropics—but suggest that such effects may have been masked in the 20^th century by rising global temperatures
Look at Glaciers Past Suggests Greenland Melting Could Rapidly Heighten Sea Level

North American Ice Sheet Dwindled Fast in Conditions Like Today's

In the face of warming climate, researchers have yet to agree on how much and how quickly melting of the Greenland ice sheet may contribute to sea level rise.
Amazon Outflow is Found to Power Ocean Capture of Carbon Dioxide

July 23, 2008

Nutrients washed out of the Amazon River are powering huge amounts of previously unexpected plant life far out to sea, thus trapping atmospheric carbon dioxide, according to a new study.
Climate Swings Have Brought Great CO2 Pulses Up From the Deep Sea

May 14, 2007

A study released on May 11, 2007 provides some of the first solid evidence that warming-induced changes in ocean circulation at the end of the last Ice Age caused vast quantities of ancient carbon dioxide to belch from the deep sea into the atmosphere. Scientists believe the carbon dioxide (CO2) releases helped propel the world into further warming.
Glacial Earthquakes Point to Rising Temperatures in Greenland

March 23, 2006

Seismologists at Columbia University and Harvard University have found a new indicator that the Earth is warming: "glacial earthquakes" caused when the rivers of ice lurch unexpectedly and produce temblors as strong as magnitude 5.1 on the moment-magnitude scale, which is similar to the Richter scale. Glacial earthquakes in Greenland, the researchers found, are most common in July and August, and have more than doubled in number since 2002.
