Abrupt ice retreat could produce ice-free arctic summers by 2040

New NCAR research indicates that Arctic sea ice will soon begin to retreat four times more rapidly than at any time since observations began. The Arctic may become nearly devoid of late summertime sea ice by about 2040 because of greenhouse gas emissions.

1. Without its insulating ice cap, Arctic surface waters warm to as much as 5 C above average
   12-12-2007 · EurekAlert!
   Record-breaking amounts of ice-free water have deprived the Arctic of more of its natural "sunscreen" than ever in recent summers. The effect is so pronounced that sea surface temperatures rose to 5 C above average in one place this year, a high never before observed, says the University of Washington oceanographer who has compiled the first-ever look at average sea surface temperatures for the region.

3. Arctic ice retreats into uncharted territory
   09-27-2007 · EurekAlert!
   On Oct. 1, the National Snow and Ice Data Center will issue a report summarizing the 2007 Arctic sea ice season, and NASA will issue a press release on a new sea ice study by NASA/JPL researchers. NASA has created new images in support of these and other reports about the remarkable decrease in sea ice this summer.

4. Older Arctic sea ice replaced by young, thin ice, says CU-Boulder study
   01-10-2008 · EurekAlert!
   A new study by University of Colorado at Boulder researchers indicates older, multiyear sea ice in the Arctic is giving way to younger, thinner ice, making it more susceptible to record summer sea-ice lows like the one that occurred in 2007.

5. Scientists: Polar ice clouds may be climate change symptom
   08-20-2007 · EurekAlert!
   As the late summer sun sets in the Arctic, bands of wispy, luminescent clouds shine against the deep blue of the northern sky. To the casual observer, they may simply be a curiosity, dismissed as the waning light of the midnight sun. But to scientists, these noctilucent ice clouds could be an upper-atmospheric symptom of a changing climate.

6. Hundreds of Antarctic Peninsula glaciers accelerating as climate warms
   06-05-2007 · EurekAlert!
   Hundreds of glaciers on the Antarctic Peninsula are flowing faster, further adding to sea level rise according to new research published this week in the Journal of Geophysical Research. Climate warming that is already causing Antarctic Peninsula increased summer snow melt and ice shelf retreat is the most likely cause.

7. First direct evidence that human activity is linked to Antarctic Ice Shelf collapse
   10-16-2006 · EurekAlert!
   The first direct evidence linking human activity to the collapse of Antarctic ice shelves is published this week in the Journal of Climate. Scientists from the British Antarctic Survey, the Center for Polar Observation and Modeling, University College London and the Katholieke Universiteit Leuven, reveal that stronger westerly winds in the northern Antarctic Peninsula, driven principally by human-induced climate change, are responsible for the marked regional summer warming that led to the retreat and collapse of the northern Larsen Ice Shelf.
