Explained in 90 Seconds: Permafrost

Glaciers. They really are the pinup geological formation for climate change. But spare a thought for permafrost. Perma-what? Answer: The gigantic carbon-rich Arctic landmass, that—until recently—has locked away its greenhouse gases in a deep freeze for millennia. That is, until man-made climate change has begun to unlock its CO2 stores, only then to be devoured by methane-spewing organisms. This microbial feast is accelerating climate change. The problem: It’s a feedback loop. The hotter it gets, the more the permafrost melts, the more CO2 is emitted. And around and around we go, in a devastating roundabout for Arctic communities and the entire globe. Continuing our “Explained in 90 Seconds” series, here’s a primer on permafrost.

THE BIG PICTURE

You expect the big picture, and it's our job at Mother Jones to give it to you. And right now, so many of the troubles we face are the making not of a virus, but of the quest for profit, political or economic (and not just from the man in the White House who could have offered leadership and comfort but instead gave us bleach).

In "News Is Just Like Waste Management," we unpack what the coronavirus crisis has meant for journalism, including Mother Jones’, and how we can rise to the challenge. If you're able to, this is a critical moment to support our nonprofit journalism with a donation: We've scoured our budget and made the cuts we can without impairing our mission, and we hope to raise $400,000 from our community of online readers to help keep our big reporting projects going because this extraordinary pandemic-plus-election year is no time to pull back.
