NASA launches airborne study of arctic atmosphere, air pollution
This month, NASA begins the most extensive field campaign ever to investigate the chemistry of the Arctic's lower atmosphere. The mission is poised to help scientists identify how air pollution contributes to climate changes in the Arctic. view more (2008-04-02)
In the Cornucopia of the European Project of Ice Coring in Antarctica: the oldest Antarctic ice core
On Tuesday 21th of December 2004 a European team involved in Epica (European Project for Ice Coring in Antarctica) reached the drilling depth of 3270.2, which is five meters above the bedrock at Dome C, on the central plateau of the east Antarctic ice sheet. The ice is melting at the bedrock and it has been decided to stop at this depth to avoid... view more... (2005-01-13)
Study breaks ice on ancient Arctic thaw
A new analysis of ocean-floor sediments collected near the North Pole finds that the Arctic was extremely warm, unusually wet and ice-free the last time massive amounts of greenhouse gases were released into the Earth's atmosphere - a prehistoric period 55 million years ago. view more (2006-08-10)
The sea-ice is getting thinner - A closer look at the climate and ecosystem of the Arctic Ocean
Large areas of the Arctic sea-ice are only one metre thick this year, equating to an approximate 50 percent thinning as compared to the year 2001. view more (2007-09-14)
Unexplored Arctic region to be mapped
A scientific expedition this fall will map the unexplored Arctic seafloor where the U.S. and Canada may have sovereign rights over natural resources such as oil and gas and control over activities such as mining. view more (2008-09-03)
Arctic climate under greenhouse conditions in the Late Cretaceous
New evidence for ice-free summers with intermittent winter sea ice in the Arctic Ocean during the Late Cretaceous - a period of greenhouse conditions - gives a glimpse of how the Arctic is likely to respond to future global warming. view more (2009-07-09)
Study: Greenland ice sheet larger contributor to sea-level rise
The Greenland ice sheet is melting faster than expected according to a new study led by a University of Alaska Fairbanks researcher and published in the journal Hydrological Processes. view more (2009-06-12)
Arctic land and seas account for up to 25 percent of world's carbon sink
In a new study in the journal Ecological Monographs, ecologists estimate that Arctic lands and oceans are responsible for up to 25 percent of the global net sink of atmospheric carbon dioxide. view more (2009-10-15)
Arctic Coring Expedition Continues to Yield New Clues About Climate Change
For the second time in as many months, the IODP Arctic Coring Expedition (ACEX) is making news with new analysis of ocean-floor sediments. view more (2006-08-10)
Will lemmings fall off climate change cliff?
Contrary to popular belief, lemmings do not commit mass suicide by leaping off of cliffs into the sea. In fact, they are quite fond of staying alive. view more (2007-04-23)
Radar opens new window into the ice for Antarctic scientists
Scientists are getting their first glimpse into the inner secrets of an ice shelf, thanks to the innovative application of a new radar technique developed by British Antarctic Survey (BAS). view more (2006-10-17)
NOAA Aircraft to Probe Arctic Pollution
NOAA scientists are now flying through springtime Arctic pollution to find out why the region is warming - and summertime sea ice is melting - faster than predicted. Some 35 NOAA researchers are gathering with government and university colleagues in Fairbanks, Alaska, to conduct the study through April 23. view more (2008-04-08)
ODP scientists say no large Northern Hemisphere ice sheets 41 million years ago
New research to test global ice volume approximately 41.6 million years ago shows that ice caps at this time, if they existed at all, would have been small and easily accommodated on Antarctica. view more (2007-08-23)
Research around the North Pole
The German research vessel Polarstern has returned today to Bremerhaven from the Arctic Sea. It has cruised as the first research vessel ever both the Northeast and the Northwest Passages and thereby circled the North Pole. view more (2008-10-21)
Climate History Rewritten: Arctic Ice an Early Arrival
For the first time, scientists have pulled up prehistoric geologic records from the frigid vault of the Arctic Ocean. One of the findings, evidence of glacial Arctic ice from 45 million years ago, recasts a critical chapter of global climate history. view more (2006-06-01)
Satellites and submarines give the skinny on sea ice thickness
This summer, a group of scientists and students - as well as a Canadian senator, a writer, and a filmmaker - set out from Resolute Bay, Canada, on the icebreaker Louis S. St-Laurent. view more (2009-09-02)
Scientists head to warming Alaska on ice core expedition
The state of Alaska has the dubious distinction of leading the lower 48 in the effects of a warming climate. Small villages are slipping into the sea due to coastal erosion, soggy permafrost is cracking buildings and trapping trucks. view more (2008-04-30)
Climate scientists spotlight Arctic warming, plight of polar bears
A climate scientist at the University of Chicago and 30 of her colleagues from across North America and Europe are urging the U.S. Fish and Wildlife Service to list the polar bear as a threatened species because global warming is melting its sea-ice habitat. view more (2006-06-19)
Icy calculations on a hot topic
University of Utah mathematicians have arrived at a new understanding of how salt-saturated ocean water flows through sea ice - a discovery that promises to improve forecasts of how global warming will affect polar icepacks. view more (2007-09-11)
Man-made soot contributed to warming in Greenland in the early 20th century
New research shows that industrial development in North America between 1850 and 1950 greatly increased the amount of black carbon--commonly known as soot-- that fell on Greenland's glaciers and ice sheets. view more (2007-08-10)
