Interesting to see how this prediction plays out. More cold and snowy winters to come - Det Internasjonale Polaråret 2007-2008 "Cold and snowy winters will be the rule, rather than the exception," says Dr James Overland of the NOAA/Pacific Marine Environmental Laboratory in the United States. Dr Overland is at the International Polar Year Oslo Science Conference (IPY-OSC) to chair a session on polar climate feedbacks, amplification and teleconnections, including impacts on mid-latitudes. Loss of sea ice causes major climate change Continued rapid loss of sea ice will be an important driver of major change in the world's climate system in the years to come.

"While the emerging impact of greenhouse gases is an important factor in the changing Arctic, what was not fully recognised until now is that a combination of an unusual warm period due to natural variability, loss of sea ice reflectivity, ocean heat storage and changing wind patterns working together has disrupted the memory and stability of the Arctic climate system, resulting in greater ice loss than earlier climate models predicted," says Dr Overland.
