Arctic Ocean could have no September sea ice if global average temperatures increase by 2 degrees

Arctic sea ice could disappear completely through September each summer if average global temperatures increase by as little as 2 degrees, according to a new study by the University of Cincinnati.  The study by an international team of researchers was published in Nature Communications.  "The target is the sensitivity of sea ice to temperature," said Won Chang, a study co-author and UC assistant professor of mathematics.  "What is the minimum global temperature change that eliminates all arctic sea ice in September? What's the tipping point?"  The study predicted that the Arctic Ocean could be completely ice-free in September with as little as 2 degrees Celsius of temperature change.  Read more....
