In the Arctic, a major variable for future climate change lives in the ground, invisible. Microbes in the layers of soil just above the frozen permafrost metabolize carbon, turning it into carbon ...

Deep beneath the Arctic permafrost and ocean sediments, a massive reservoir of methane, often referred to as a “time bomb,” poses a significant threat to our climate. This potential for rapid release ...

Methane hydrates, ice-like solids that trap methane within a crystalline structure, typically form under low-temperature, high-pressure conditions known as stability zones, typically found beneath ...

The structure of the plant communities that grow on the thawing permafrost in the Arctic is changing, with grasses displacing slower-growing shrubs. Although these grasses bind more carbon dioxide ...
