Measuring the Melting Arctic Sea Ice | Miller-McCune Online

While the world’s eyes focus on the catastrophe in the Gulf, climatologists are tracking a decades-old cataclysm at the top of the world — dwindling Arctic sea ice.

This year is projected to surpass 2007’s summer sea ice minimum, when sailboats were seen navigating their way through large cracks in polar ice floes.

“Where Arctic ice used to be 3- to 5-meters thick in most places, now it’s tough to find ice that’s over 3-meters thick,” explained Ignatius Rigor, a climatologist at the University of Washington in Seattle. “Most of the Arctic is covered by 2-year-old ice. It used to be covered by ice that was 30 years old [why only 30?].”

Projections call for the Arctic Ocean to become open water, at least in summer, as early as 2040. The last three decades of loss — in both the volume and extent of summer sea ice and in more permanent multi-year Arctic sea ice packs — are climatologically unprecedented [how, specifically, would we know this?] during the last few thousand years. And such loss can’t be explained by any known natural variability.
