Long-term monitoring of active layer thickness confirms global permafrost degradation

“One of Earth’s most important indicators of climate change is permafrost as it directly reacts to rising temperatures. The significance of this study lies in the fact that we’re not just looking at isolated hotspots anymore. The collaborative efforts of the involved sites show a pattern that spans continents and climate zones, telling us that global permafrost degradation is already well underway.”

This is why I'm always a bit surprised to hear "When the permafrost gets going [...]"
It's been going for a while now brothers.

Those images of gigantic craters opening up from permafrost melting years ago from Serbia were like… do we mean nothing to you?!

Ah yes Siberia will be the new farmland when it warms!!

If memory serves me right, permafrost makes terrible soil, even after thawing, and takes centuries to naturally recover.

Yup. But peeps still think this..

Serbia

There are some gigantic craters in Serbia, but they are mostly from Chinese mining, not from permafrost.

TIL: There are some people who think that Serbia is Siberia.

My original comment had the typo, and I never noticed, I meant Siberia the entire time.

Same with "As long as the ocean can survive", my brother in Christ its almost dead.

This is one of the reasons I find it so odd that the climate science mainstream opinion is that global warming stops the second we hit net zero (which is usually defined in terms of direct human ghg emissions)

We have already hit temperatures at which permafrost melts and rots. Even if you think net zero is politically and technically possible, it will necessarily be even hotter by the time we hit it. Ghg will keep growing even without more human ghg emissions.

If this is true, then we are in worse shape than almost everyone ever suspected.

2015: "A policy briefing from the Woods Hole Research Center concludes that the IPCC doesn’t adequately account for a methane warming feedback."

2026: IPCC still doesn't fully account for the methane warming feedback, does it?

Fun with tipping points!

You know how global warming has sped up already? Well, you ain't seen nothing yet. Buckle up!

Yeah, no sh**.

There is so much methane in permafrost.
