Canada's arctic climate changing faster than expected

Climate change is transforming the Arctic environment faster than expected and accelerating the disappearance of sea ice, scientists said on Friday in giving their early findings from the biggest-ever study of Canada's changing north.

"(Climate change) is happening much faster than our most pessimistic models expected," said David Barber, a professor at the University of Manitoba and the study's lead investigator, at a news conference in Winnipeg.

Models predicted only a few years ago that the Arctic would be ice-free in summer by the year 2100, but the increasing pace of climate change now suggests it could happen between 2013 and 2030, Barber said.

Scientists link higher Arctic temperatures and melting sea ice to the greenhouse gas emissions blamed for global warming.

The Arctic is considered a type of early-warning system of climate change for the rest of the world.
