Arctic waders do not own a capital - Small migrating birds collect egg energy from snowy breeding grounds
A 20-year old scientific case is solved. Waders, small birds like ringed plover and purple sandpiper, travelling to the North Pole area to breed, do not bring extra food from home with them. Instead they do what ecologists thought of as nearly impossible: they find enough food in the snowy tundra surrounding their nests to lay eggs quickly. Marcel... view more... (2001-10-25)
Canada's shores saved animals from devastating climate change
The shorelines of ancient Alberta, British Columbia and the Canadian Arctic were an important refuge for some of the world's earliest animals, most of which were wiped out by a mysterious global extinction event some 252 million years ago. view more (2008-10-01)
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)
Global warming could lead to a greener Greenland (embargoed until 18.00 BST)
Research published in Nature suggests that enough greenhouse gases could be in the atmosphere as early as 2050 to melt the massive ice-sheet that covers Greenland. As a result, sea levels could rise by around seven metres over the next 1,000 years. Along with colleagues in Belgium and Germany, Dr Jonathan Gregory, of the Centre for Global... view more...

Earliest evidence of modern humans in Europe discovered by international team
Modern humans who first arose in Africa had moved into Europe as far back as about 45,000 years ago, according to a new study by an international research team led by the Russian Academy of Sciences and the University of Colorado at Boulder. view more (2007-01-12)
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)
Melting Greenland Ice Sheets May Threaten Northeast United States, Canada
Melting of the Greenland ice sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax, and other cities in the northeastern United States and Canada. view more (2009-05-28)
Research finds that Earth's climate is approaching 'dangerous' point
NASA and Columbia University Earth Institute research finds that human-made greenhouse gases have brought the Earth's climate close to critical tipping points, with potentially dangerous consequences for the planet. view more (2007-06-01)
Deep thinking: Scientists sequence a cold-loving marine microbe
At home in the deep, dark Arctic Ocean, the marine bacterium Colwellia psychrerythraea 34H keeps very cool-typically below 5° degrees Celsius. How does the bacterium function in this frigid environment? To find out, scientists at The Institute for Genomic Research (TIGR) and collaborators have sequenced and analyzed C. psychrerythraea's... view more... (2005-07-26)

Ozone and UV over Europe: no sign of improvement
"The occurrence of ozone mini-holes over Europe increases and any ozone layer recovery could only become measurable around 2010 at the earliest" concludes an assessment report, released today, on European research in the stratosphere. The report concerns loss of ozone, increases in ultraviolet radiation as well as the impact of aircraft... view more... (2002-01-21)
