California (U.S.), Nov 25 (Canadian-Media): According to the latest research predictions at the University of California's Center for Climate Science, the Arctic could be "functionally ice-free" by September 2044, and no later than 2067, assuming no changes to global carbon emissions, according to research published in the journal Nature Climate Change, media reports said.
September is when the effect of summer's heat shows up in the ice pack making the Arctic sea ice pack is at its thinnest.
Ice free means there would be fewer than one million square kilometres of Arctic sea ice -- mostly representing thick, multi-year ice close to coastal areas of Greenland and in the Arctic archipelago, compared with the current minimum six million square kilometres of Arctic sea ice.
With declining sea ice, Arctic's ability to absorb 90 percent of incoming solar energy (heat) which would mean it would quicken global warming.
On the other hand sea ice which absorbs just 20 percent of that energy and reflects away the rest of heat energy which helps regulate climate. It's absence encourages warming.
