something is not right at the highest latitudes of the globe

WINTER HAS EXTENDED ITS GRIP on the Arctic, drop­ping a cur­tain of dark­ness on the top of the world. But at least one part of the Arctic is re­sisting its grasp. In what’s be­coming an un­for­tu­nately common story, sea ice growth is stalling out in one of the gateway seas leading to the heart of the Arctic Ocean. The Chukchi Sea cur­rently has a sea ice ex­tent more rem­i­nis­cent of summer than early winter, a sign that some­thing is not right in the wa­ters at the highest lat­i­tudes of the globe.

The Chukchi Sea sits be­tween northern Alaska and Russia. That makes it a cru­cial bridge to the Bering Sea, a place for the sea to latch on and spread its icy ten­drils to the south. But this winter so far has seen ice suffer. After bot­toming out in Sep­tember, the ice in the Chukchi Sea has failed to re­bound.

Usu­ally, the dip in tem­per­a­tures cou­pled with the lack of sun­light causes ice to build back up quickly. This year, though, growth has been much slower. Sea ice data shows that ice ex­tent is the lowest on record for this time of year by a long shot.

The para­graphs above were taken from “Some Arctic Sea Ice Is Acting Like It’s Mid-Summer” by Brian Kahn for Giz­modo (No­vember 15, 2019).
