Arctic sea ice this summer shrank to its second lowest level since scientists started to monitor it by satellite, with scientists saying it is another ominous signal of global warming. The National Snow and Ice Data Center in Colorado said the sea ice reached its summer low point on Saturday, extending 4.14m sq km (1.6m sq miles). It was an unusual year for sea ice in the Arctic, Serreze said. Those storms normally keep the Arctic cloudy and cooler, but that didn’t keep the sea ice from melting this year, he said. “What happens in the Arctic doesn’t stay in the Arctic,” Pennsylvania State University climate scientist Michael Mann said.
