Around 11% of the Earth's land mass is covered by permafrost. But its delicate balance is being threatened by climate change.

What happens? The methane stored will get out and make the climate change even worse because it's way worse than carbon dioxide.

4:04 “There’s estimated to be four times more carbon trapped in permafrost than all of the human-generated CO₂ emissions in modern history. The release into the atmosphere of even a fraction of this as carbon dioxide and methane will have a profound effect on the climate.”

The lede is buried exactly at the midpoint of the video.

This should be taught in high schools!

When I was in Svalbard a couple years ago. One day, it was so insanely hot I had to walk around in a T-shirt! I talked to a man who had lived up there for 40 years. He said it was the hottest day that early in the season he had ever seen in the 40 years he was up there.

It was shocking to see the ice shelf broken up into melting ice. Heartbreaking. (I also had to wear a T-shirt one day in Antarctica) Folks, this is very real.

People will watch this and a week later continue winging about how wind turbines aren't very nice to look at

Jesus Christ, the comments in this video make me root for global warming to wipe us all

Exponential melting. I wonder if we've reached or passed the tipping point yet.

When permafrost thaws, it releases vast amounts of greenhouse gases like carbon dioxide and methane, exacerbating global warming and leading to a feedback loop of further thawing. This process can destabilize ecosystems, infrastructure, and communities in Arctic regions. The critical question is: How can we mitigate the impacts of permafrost thaw and prevent the acceleration of climate change?

Unfortunately the way how the world politics goes there probably will never be any meaningful changes to stop climate change until there are severe effects that is felt by a superpower nation/s

Until the, "it's not my problem, the next generation has to deal with it", mindset is educated nothing will change. And the people with that mindset seem rather proud of their ignorance, so.

Then the north is permafucked, and the coast is permaflooded.

7:00 "is there a way of slowing down, or stopping this!" ... "No, not really"

<3 It's sad to see a way of life & many generations of memories dissipate directly underneath you. Many Canadians & others feel this connection with Northern Territories, peoples, tongues, tribes, & ways of life in one way or another. Truly devastating...
