More alarmingly warm weather in northern regions unaccustomed to such heat this early in the year.
(CNN)Much of the country will see a dive in temperatures this weekend, but Alaska continues to bake with record highs.
Parts of the state have had their earliest 70-degree readings on record. Klawock, a town in southeastern Alaska, reached 70 F on March 19 -- the earliest any spot in the state has hit that high.
More records are expected to be broken this weekend, with temperatures soaring as much as 50 degrees above normal in
the fastest-warming state.
And of course the thing about thawing permafrost is it’s potential to drive a feedback loop triggering the release of massive amounts of methane into the earth’s atmosphere, making global warming a runaway self sustaining process, with little prospect for human mitigation or intervention.
