It takes a while for the data to get settled in, and I'm in no particular hurry. According to the National Snow and Ice Data Center September sea ice extent over the arctic pole was 5.36 million square kilometers. That's more ice than last year, but less ice than average. There are many efforts to intepret the data. In my view the skeptics seem more reasonable in light of this data point than they would had sea ice extent declined from the previous year. I remain concerned about the polar bear's habitat, and the possibility of extinction.
