Bubbles of methane coming from lakes in the Arctic are being measured from space so scientists can better understand their role in emissions of the potent greenhouse gas. A report from NASA Earth ...

In the last couple of years, you must have seen those videos of people skating or playing around on ice with the surrounding ...

The ground is made up of both ice and frozen soil called permafrost. The ground is made up of both ice and frozen soil called permafrost. As the permafrost thaws, the ground sinks and floods. The ice ...

One of the many greenhouse gases contributing to global warming is methane. Methane is emitted in a lot of ways, including from lakes across Alaska. However, studies on how much methane flows up from ...

So as these bubbles come up through the water and then they often will float at the lake surface for a minute and then pop, they’re releasing almost pure methane. It’s often 80, 90% methane into the ...

In the eastern part of Lake Constance, the second largest prealpine lake in Europe, about 500 pockmarks (morphological depressions on the lake floor) were recently discovered. The diameters of these ...

Spring blossoms have started in most parts of the country, but in Alaska the ice is still melting. I’m a climate change scientist and a mother, and the best way I’ve found to talk with my kids about a ...

Across the Arctic, there are lakes where the water appears to boil. Where "drunk" forests crash into the water. Where huge sinkholes appear following mammoth explosions—one witness to such an event ...

A research team has developed a way to use satellite images to determine the amount of methane being released from northern lakes, a technique that could help climate change modelers better account ...

BAYOU CORNE — High water from recent heavy rains revealed small sources of natural gas venting in the Bayou Corne community, a swampland settlement that has been evacuated for more than five months ...
