climate change


It’s been a chilly winter here in the Interior and elsewhere around the state. But for the Arctic Ocean, it’s been one long warm spell. That’s led to another record-low year for formation of Arctic winter sea-ice cover.


It’s been a relatively cool and snowy winter here in the Interior, compared with the past couple of winters. But climate experts say the Arctic has been warmer than average. They say that’s why it appears this year’s maximum Arctic sea-ice cover, measured near the end of winter, is likely to set another record for the smallest maximum on record.

The U.S. Arctic Research Commission set off alarms last week when a staffer inadvertently suggested the agency would halt its Twitter feed.

National Weather Service

The weather service’s long-term forecast calls for normal temperatures and precipitation through the rest of the winter – except, possibly, in western Alaska.

A record-warm year in the Arctic, partly due to climate change …


Twenty-sixteen was the warmest year in Alaska since the National Weather Service began keeping records in the state more than a hundred years ago. Two weather-service climate specialists say that’s mainly because of extraordinarily warm ocean water, which in turn helped generate above-normal precipitation – especially in the Interior.
