Arctic sea ice appears likely to reach a record minimum extent this year; as Greg Laden says, “It is almost like the Earth is warming up or something.” The lowest extent of Arctic sea ice on record (since observations began in 1979) occurred in 2012, the second-lowest in 2007, and the third-lowest in 2015. On Stoat, William M. Connolley says it’s currently at an “all-time low for the time of year, but only just, which is better than its been for the last few months.” While the fate of the entire human race may hinge on the effects of global warming, Connolley also has $10,000 on the line. Will the extent of sea ice drop below 3.1 million square kilometers this September? And will we experience ice-free Arctic summers in the near future?
