Melting Permafrost in Siberia is Creating Explosive Craters

Imagine this: you’re walking across the frozen tundra in Siberia and—whoa—there’s a giant hole in the ground, big enough to swallow a house. No, it’s not a scene from a sci-fi movie. These craters are real, and scientists have been finding more of them over the past decade. The big question: what’s going on?

What’s Hiding Under the Ice?

Siberia is covered in permafrost, soil that usually stays frozen solid all year long. But, as the planet heats up, permafrost is thawing faster than ever. That’s already causing big problems you can see—like sinkholes opening up, telephone poles leaning, roads and runways cracking, and forests where trees just topple over.

But the bigger mystery is what’s hidden inside the thawing ground. Scientists, like Dr. Kimberly Miner, worry that as permafrost melts, it could release things that have been trapped for thousands—or even millions—of years. That includes dangerous chemicals, like DDT, and ancient microbes we know almost nothing about.

Exploding Craters

Here’s where it gets interesting (and a little scary): under the permafrost, there are pockets of super salty water called cryopegs, plus frozen cage-like structures of methane gas known as methane hydrates.

When surface ice melts, water trickles down and mixes with these layers. That mix—along with warming temperatures—causes pressure to build. At the same time, methane hydrates start breaking apart, releasing gas.

And then? The ground above just can’t take it anymore. Kaboom! The land explodes like a shaken soda can, shooting methane into the air and leaving behind a massive crater.

Why This Matters for Everyone

What happens in the Arctic doesn’t stay in the Arctic. These craters might be thousands of miles away, but they’re part of a global story. Methane is a supercharged greenhouse gas—more than 25 times stronger than carbon dioxide at trapping heat. So when it escapes into the air, it makes climate change even worse.

It’s a feedback loop: warming melts permafrost → melting releases methane → methane causes more warming. Yikes.

Scientists believe we’ll see more of these craters as the Arctic keeps heating up. Think of them as Earth’s warning flares—giant holes in the ground saying, “Hey! This is what out-of-control warming looks like.”

What Can We Do?

Here’s the thing: we actually have a say in this. Every step we take to cut greenhouse gas emissions helps break this dangerous cycle. That means more clean energy, fewer fossil fuels, and smarter choices in our daily lives—whether that’s driving less, eating more plant-based meals, or supporting climate-friendly policies and renewable energy.

The tundra may be exploding, but our future doesn’t have to.
