No smoking gun — yet
By Bob Berwyn
FRISCO — There’s no doubt that the continuing decline of Arctic sea ice is going to affect climate and weather across the northern hemisphere, but researchers are still trying to pinpoint exactly what the impacts will be.
In one recent study, scientists with the Cooperative Institute for Research in Environmental Science found that as sea ice disappeared, the areas of relatively warm open water began to strongly influence the atmosphere, increasing surface temperatures in the region, and shifting low- and high-pressure zones around most markedly in the fall and winter.
“The way I see it, it’s one of the wild cards out there,” said Mark Serreze, director of the National Snow and Ice Data Center. “The issue is just what those changes are going to look like. That’s what we’re really still grappling with, we don’t have a handle on this … Is there a smoking gun? No, not yet,” Serreze said, discussing the findings of the new study. Continue reading
