Climate change 'irreversible' as Arctic sea ice fails to re-form
Sea ice in the Arctic has failed to re-form for the second consecutive winter, raising fears that global warming may have tipped the polar regions in to irreversible climate change far sooner than predicted.
Satellite measurements of the area of the Arctic covered by sea ice show that for every month this winter, the ice failed to return even to its long-term average rate of decline. It is the second consecutive winter that the sea ice has not managed to re-form enough to compensate for the unprecedented melting seen during the past few summers.
Scientists are now convinced that Arctic sea ice is showing signs of both a winter and a summer decline that could indicate a major acceleration in its long-term rate of disappearance. The greatest fear is that an environmental "positive feedback" has kicked in, where global warming melts ice which in itself causes the seas to warm still further as more sunlight is absorbed by a dark ocean rather than being reflected by white ice.
Winter warmest ever on record in Canada
THE ASSOCIATED PRESS
TORONTO -- The winter of 2005-2006 has been Canada's warmest on record and the federal agency Environment Canada said Monday it was investigating whether it's a sign of global warming.
Between December and February, the country was 3.9 degrees above normal - the warmest winter season since temperatures were first recorded in 1948. Environment Canada climatologist Bob Whitewood said it smashed the previous record set in 1987 by 0.9 degrees.
It was especially balmy in Alberta, Saskatchewan and the Northwest Territories, where temperatures were 6 to 8 degrees above normal.
Ottawa, March 7, 2002 - This winter was the warmest on record for Southern Ontario and Southern Quebec, according to Environment Canada weather experts. The rest of Canada also saw unusually mild temperatures this winter, making this the 19th consecutive season above normal since the summer of 1997. Environment Canada records for the months of December, January and February indicate that:
* The winter in Southern Ontario and Southern Quebec was the warmest since national records began in 1948. The average temperature was 4.8 °C above normal, an amazing departure from average conditions.
