Siberian lakes burp "time-bomb" greenhouse gas
Frozen bubbles in Siberian lakes are releasing methane, a greenhouse gas, at rates that appear to be "... five times higher than previously estimated" and acting as a positive feedback to climate warming, said Katey Walter, in a paper published today in the journal Nature.   view more (2006-09-08)

Most of Arctic's Near-Surface Permafrost May Thaw by 2100
Global warming may decimate the top 10 feet (3 meters) or more of perennially frozen soil across the Northern Hemisphere, altering ecosystems as well as damaging buildings and roads across Canada, Alaska, and Russia.   view more (2005-12-20)

The world's oldest bacteria
A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found.   view more (2007-08-28)

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)

Greenhouse gas bubbling from melting permafrost feeds climate warming
A study co-authored by a Florida State University scientist and published in the Sept. 7 issue of the journal Nature has found that as the permafrost melts in North Siberia due to climate change, carbon sequestered and buried there since the Pleistocene era is bubbling up to the surface of Siberian thaw lakes and into the atmosphere as methane, a... view more...

The tropics play a more active role than was thought in controlling the Earth's climate
Researchers from the Universitat Aut√≤noma de Barcelona and Durham University (UK) have discovered that a million years ago, global climate changes occurred due to changes in tropical circulation in the Pacific similar to those caused by El Ni√ħo today.   view more (2005-10-12)

Peat and forests save permafrost from melting
Permafrost may be buffered against the impacts of climate change by peat and vegetation present in the northern regions, according to a study by McMaster researchers.   view more (2007-09-14)

Glimpse to past adds weight to global warming forecasts
A new examination of the period of global warming that planet Earth underwent 130,000 years ago is helping scientists to confirm the accuracy of projections for the next century - particularly over Canada's North.   view more (2006-03-24)

Woolly mammoth genome comes to life

Frozen Natural Gas Discovered at Unexpectedly Shallow Depths Below Seafloor
An international team of research scientists has reported greater knowledge of how gas hydrate deposits form in nature, subsequent to a scientific ocean-drilling expedition off Canada's western coast.   view more (2006-08-22)

Study rules out ancient 'bursts' of methane from seafloor deposits
A dramatic increase about 12,000 years ago in levels of atmospheric methane, a potent greenhouse gas, was most likely caused by higher emissions from tropical wetlands or from plant production, rather than a release from seafloor methane deposits.   view more (2006-08-25)

Woods Hole Research Center scientist furthering discussion of soil carbon decomposition
Significantly more carbon is stored in the world's soils than is present in the atmosphere. In a process called a "positive feedback," global warming may stimulate decomposition of soil organic matter, thus releasing heat-trapping carbon dioxide gas to the atmosphere, possibly causing the rate of global warming to increase further.   view more (2006-03-09)

Thawing permafrost a significant source of carbon
Permafrost, permanently frozen soil, isn't staying frozen and a type of soil called loess contained deep within thawing permafrost may be releasing significant, and previously unaccounted for, amounts of carbon into the atmosphere.   view more (2006-06-16)

Lands surface change on Alaska tundra creating longer, warmer summers in Arctic
A gradual lengthening of the snow-free season in Alaska's tundra, and a corresponding northward progression of the growth of shrubs and trees, may be creating a cycle of warmer and longer summers in the Alaskan Arctic.   view more (2005-09-23)

Ancient greenhouse emissions possible lessons for modern climate
Humans are performing a high-stakes climate experiment by burning fossil fuels that release heat-trapping greenhouse gases into the atmosphere.   view more (2006-02-17)

Bad sign for global warming: Thawing permafrost holds vast carbon pool
Permafrost blanketing the northern hemisphere contains more than twice the amount of carbon in the atmosphere, making it a potentially mammoth contributor to global climate change depending on how quickly it thaws.   view more (2008-09-04)

Scientists to employ Arctic ice and polar bears to protect diversity of world's crops
On an island near the North Pole, heads of State from five Nordic countries and the Global Crop Diversity Trust laid the cornerstone today for a "fail-safe" seed vault to be carved into an Arctic mountain. The vault will ensure the long-term survival of the world's vital food crops.   view more (2006-06-19)

Chance discovery: Alaska Range glacier surges
There is evidence that the McGinnis Glacier, a little-known tongue of ice in the central Alaska Range, has surged.   view more (2006-03-16)
