Last week, an international group of researchers released their best estimates for Arctic sea ice extent over the summer melt season. The scientists are compiling their estimates so that they can better predict changes in Arctic sea ice. Credit: SEARCH Sea Ice Outlook
Average Arctic sea ice extent this May was the third lowest in the satellite record. Does that mean that ice extent will reach a new record low this summer? Or will it recover somewhat over recent years?
Last week sea ice scientists from around the world shared their best answers to those questions, in the June report of the Sea Ice Outlook. For the report, the researchers used a variety of methods to predict how sea ice will behave this summer, such as statistical methods or computer models. Continue reading
Scientists expect the Arctic to lose most of its summer ice cover by the end of this century, and are working to determine when this might happen. Here, open water in Fram Strait, in the Canadian Arctic, is interspersed with chunks of sea ice. Credit: Angelika Renner
If you have been following the topic of Arctic sea ice, you have probably seen a few headlines warning that the Arctic is about to lose its summer ice cover. Although scientists agree that Arctic sea ice is declining, they have published several different estimates of when the last of the sea ice will melt in summer, leaving more ocean surface open to absorb heat and add to global warming. What is behind all these different predictions? Continue reading
