Arctic Sea Ice Sees 'Significant Increase' 
in Size Following 'Extreme Cold'
______________________________________


 

15 Feb 08 - Scientists say the extreme cold temperatures across northern Canadaa in the last few weeks has been helping winter sea ice grow across the Arctic, where the ice shrank to record-low levels last year. 

Temperatures have stayed well in the -30s C and -40s C range since late January throughout the North, with the mercury dipping past -50 C in some areas. Satellite images are showing that the cold spell is helping the sea ice expand in coverage by about 2 million square km, compared to the average winter coverage in the previous three years. 

"It's nice to know that the ice is recovering," Josefino Comiso, a senior research scientist with the Cryospheric Sciences Branch of NASA's Goddard Space Flight Centre in Maryland, told CBC News on Thursday. [……] Winter sea ice could keep expanding. The cold is also making the ice thicker in some areas, compared to recorded thicknesses last year, Lagnis added. "The ice is about 10 to 20 centimetres thicker than last year, so that's a significant increase," he said. If temperatures remain cold this winter, Langis said winter sea ice coverage will continue to expand.
