Climate change is transforming the Arctic into an entirely unfamiliar region, scientists say
of the rest of the globe — the downward trend in the minimum ice extent during the past 42 years is 13.4 percent per decade, compared with the 1981-2010 average. The 14 years with the lowest extents in the satellite era have all occurred in the past 14 years, the NSIDC found.
According to Serreze, the ice cover north of Siberia entered the summer melt season in a vulnerable position. This sea ice was thinner than average because of prevailing offshore winds in that region throughout the winter that exported thicker ice floes to the north, across the top of the planet. “These heat waves are getting hotter, and the cold waves are not as cold,” Serreze said in an interview.This melt season featured record-breaking Arctic wildfires in the Siberian Arctic, with concerns raised about melting permafrost, which acts like a greenhouse gas bank by keeping these gases locked away in the frozen soil.
