59% Chance of Record Low Arctic Sea Ice in 2008
New calculations by CIRES affiliate Jim Maslanik and CU's Sheldon Drobot indicate the record low minimum extent of sea ice across the Arctic last September has a three-in-five chance of being shattered again in 2008 because of continued warming temperatures and a preponderance of younger, thinner ice. In January 2008, a team led by Maslanik and involving CIRES and NSIDC's Julienne Stroeve concluded there had been a nearly complete loss of the oldest, thickest Arctic sea ice. The team calculated that 58 percent of the remaining Arctic sea ice was thin and more vulnerable to melt. [ source: News & Events ]

Ozone Hole Recovery Will Reshape Climate Change
A full recovery of the stratospheric ozone hole could strongly modify climate change in the Southern Hemisphere and possibly amplify warming of the Antarctic continent, reports a new CU, NOAA, and NASA study led by CIRES' Judith Perlwitz. According to the study, which appears this week in Geophysical Research Letters, ozone depletion -- by affecting atmospheric circulation -- has played an important role in keeping Antarctica's interior cool. A full ozone recovery is expected to reverse these trends. [ source: News & Events ]
