Arctic Melting, Worst Summer Ever, Science News, Sept. 14
Researchers from the University of Bremen announced that this year’s annual amount of Arctic sea ice reached an all time low of 4.240 million square kilometers, breaking the 2007 record of 4.267 million square kilometers. Using a different algorithm of estimation, the Japan Aerospace Exploration Agency center found that this year’s ice level was only near its record low: 4.34 million square kilometers, compared with 4.17 million square kilometers observed in 2007. Whether the true figure is near or less than that of the historic low in 2007, climate scientists worry that there will be a continual trend of thinning ice.
