The mountains of British Columbia cradle glaciers in west Canada are in
rapid retreat, which has become a major climate change issue, a media
report said Sunday, citing an American state-of-the union report on
climate change.
"Most glaciers in Alaska and British Columbia are
shrinking substantially," Xinhua quoted The Canadian Press as citing the
US National Climate Assessment. Glaciers in British Colombia and
America's northern state of Alaska are losing 20 to 30 percent of what
is melting annually from the Greenland Ice Sheet, the report said. That
amounts to about 40 to 70 gigatons per year, or about 10 percent of the
annual discharge of the Mississippi River, it added.
"The global
decline in glacial and ice-sheet volume is predicted to be one of the
largest contributors to global sea- level rise during this century," the
report said.Brian Menounos, a geography professor at the University
of Northern British Columbia and one of the scientists involved in
cross-border, multi-agency research into glacial loss, said he was
concerned about the melting speed of the glaciers.
"We've seen an
acceleration of the melt from the glaciers," he said, adding, "When we
start to look at some of these individual mountain ranges, we're seeing
some rates that are truly exceptional."There are 200,000 glaciers on Earth, 17,000 of them in British Columbia, according to the report.
