U. of Colorado study shows massive CO2 burps from ocean to atmosphere at end of last ice age
A University of Colorado at Boulder-led research team tracing the origin of a large carbon dioxide increase in Earth's atmosphere at the end of the last ice age has detected two ancient "burps" that originated from the deepest parts of the oceans. view more (2007-05-11)
Study reveals lakes a major source of prehistoric methane
A team of scientists led by a researcher at the University of Alaska Fairbanks has identified a new likely source of a spike in atmospheric methane coming out of the North during the end of the last ice age. view more (2007-10-26)
Foxes get frisky in the far north
Bees do it, chimps do it- Now it seems Arctic foxes do it, too. New research looking at the DNA fingerprints of canids in the Far North has revealed that foxes once thought to be monogamous are in fact quite frisky. view more (2007-07-18)
Dissapearing arctic lakes linked to climate change
Continued arctic warming may be causing a decrease in the number and size of Arctic lakes. The issue is the subject of a paper published in the June 3 issue of the journal "Science." The paper, titled, "Disappearing Arctic Lakes" is the result of a comparison of satellite data taken of Siberia in the early 1970s to data from... view more... (2005-06-06)
New Antarctic seabed sonar images reveal clues to sea-level rise
Motorway-sized troughs and channels carved into Antarctica's continental shelves by glaciers thousands of years ago could help scientists to predict future sea-level rise. view more (2009-05-05)
Arctic Map plots new 'gold rush'
Researchers at Durham University have drawn up the first ever 'Arctic Map' to show the disputed territories that states might lay claim to in the future. view more (2008-08-06)
European lead in reading past climates from ice cores
Climate change is a reality today, but how can we find out about the future dangers it poses" What we really need is a full record of the Earth's climate for several hundred thousand years, complete with samples of air from different epochs that can be taken to the lab for analysis. view more (2007-10-12)
Warming could free far more carbon from high Arctic soil than earlier thought
Scientists studying the effects of carbon on climate warming are very likely underestimating, by a vast amount, how much soil carbon is available in the high Arctic to be released into the atmosphere, new University of Washington research shows. view more (2005-12-06)

Last time carbon dioxide levels were this high: 15 million years ago, scientists report
You would have to go back at least 15 million years to find carbon dioxide levels on Earth as high as they are today, a UCLA scientist and colleagues report Oct. 8 in the online edition of the journal Science. view more (2009-10-09)
Decline in greenhouse gas emissions would reduce sea-level rise, save Arctic Sea ice
The threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70 percent this century, according to a new analysis. view more (2009-04-15)
First evidence of under-ice volcanic eruption in Antarctica
The first evidence of a volcanic eruption from beneath Antarctica's most rapidly changing ice sheet is reported this week in the journal Nature Geosciences. The volcano on the West Antarctic Ice Sheet erupted 2000 years ago (325BC) and remains active. view more (2008-01-21)
Satellite spies on doomed Antarctic ice shelf
Satellite images have revealed the collapse of Larsen B ice shelf on the Antarctic Peninsula fulfilling predictions made by British Antarctic Survey (BAS) scientists. The collapse of the 3250 km2 ice shelf is the latest drama in a region of Antarctica that has experienced unprecedented warming over the last 50 years. Earlier this month Ted Scambos... view more...

Working with Inuit Community Is Part of Scientific Expedition
Research on global warming is drawing scientists in increasing numbers to the world's polar regions. But as scientists make more journeys northward, some of them find that their mission now extends beyond the ice or sediment samples they will bring back to their labs to analyze. view more (2007-05-17)
Melting of the Greenland ice cap may have consequences for climatic change
According to two international-research studies on the last ice age, studies with the participation of Dr Rainer Zahn, research professor in the ICREA at the UAB Institute of Environmental Science and Technology (ICTA), before the great ice sheets of the Arctic Ocean began to melt, early sporadic episodes of melting of the old ice sheet which... view more...

Greenland's thinning ice sheet could be saved by snow
A study conducted by an expert at the University of Sheffield and officials at NASA has found that while Greenland's ice is certainly thinning, snowfall in some areas is increasing, with levels in south-east Greenland in the past year being three times higher than is usual. This opens debate as to how global warming will affect Greenland's ice... view more... (2004-12-20)
Deep in Arctic Mud, Geologists Find Strong Evidence of Climate Change
How severe will global warming get? Jason P. Briner is looking for an answer buried deep in mud dozens of feet below the surface of lakes in the frigid Canadian Arctic. view more (2007-01-19)
Pollutant haze heats the Arctic
Arctic climate already is known to be particularly prone to global warming caused by industrial and automotive emissions of carbon dioxide and other greenhouse gases. view more (2006-05-11)
Antarctic ice loss
Increasing amounts of ice mass have been lost from West Antarctica and the Antarctic peninsula over the past ten years, according to research from the University of Bristol and published online this week in Nature Geoscience. view more (2008-01-14)
New clues to ozone depletion
Laerge quantities of ozone-depleting chemicals have been discovered in the Antarctic atmosphere by researchers from the University of Leeds, the University of East Anglia, and the British Antarctic Survey. view more (2007-07-27)
