Study tracks links between sea ice and climate | Summit County Citizens Voice via @bberwyn
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.
“It is widely accepted that if we lose the Arctic sea ice cover, we will have responses in the atmospheric circulation system,” he continued. The real basic reason for that is, by warming the arctic as much as we are doing, you change the temperature gradient from the mid-latitudes to the poles. The gradient is what drives the weather patterns,” he said.
