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 19th annual Alaska Forum on the Environment wraps up today after five days of presentations on environmental challenges confronting the state. Dozens of organizers and more than a thousand participants came to the event to find solutions, but many also found themselves dealing with a new challenge stemming from the changed political environment.

The U.S. Arctic Research Commission set off alarms last week when a staffer inadvertently suggested the agency would halt its Twitter feed. The resulting uproar followed similar backlash over real blackouts at other federal agencies, resulting from a Trump administration gag order on their distribution of climate change information.

The National Weather Service says the cold that’s gripped the Interior for the past few weeks will finally give way this week to milder temperatures. The weather service’s long-term forecast calls for normal temperatures and precipitation through the rest of the winter – except, possibly, in western Alaska.

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.
