Drastic emission cuts can save Arctic: Study

WASHINGTON: Cutting greenhouse gases by 70 percent this century would spare the planet the most traumatic effects of climate change, including the massive loss of Arctic sea ice, a study said on Tuesday.

Warming in the Arctic would be almost halved, helping preserve fisheries, as well as sea birds and Arctic mammals like polar bears in some regions, according to scientists at the National Center for Atmospheric Research (NCAR).

But the massive cuts of greenhouse gas emissions advocated by the researchers would only "stabilize the threat of climate change and avoid catastrophe," said NCAR scientist Warren Washington, the study's lead author.
