dryriver quotes a report from CNN: For what appears to be the first time since scientists began keeping track, sea ice in the Arctic and the Antarctic are at record lows this time of year. “It looks like, since the beginning of October, that for the first time we are seeing both the Arctic and Antarctic sea ice running at record low levels,” said Walt Meier, a research scientist with the Cryospheric Sciences Laboratory at NASA’s Goddard Space Flight Center, who has tracked sea ice data going back to 1979. While it is too early to know if the recent, rapid decline in Antarctic sea ice is going to be a regular occurrence like in the Arctic, it “certainly puts the kibosh on everyone saying that Antarctica’s ice is just going up and up,” Meier said. The decline of sea ice has been a key indicator that climate change is happening, but its loss, especially in the Arctic, can mean major changes for your weather, too. The report notes that air temperatures in the Arctic have been exceeding 35 degrees Fahrenheit (20 degrees Celsius) above average, while “sea ice in the northern latitudes is at a lower level than ever observed for this time of the year.” October and November is when the Arctic region typically gains ice. This year, air temperatures are staying much warmer and closer to the freezing mark of 32 degrees Fahrenheit. What’s more is that water temperatures in the Arctic Ocean are several degrees above average, as a result of having less sea ice.
