Science Kids Arctic Tundra Biome V1-0001 Permafrost is a layer of permanently frozen soil, rock, or sediment found in the Arctic tundra and other cold regions. It plays a crucial role in regulating the Earth's climate by storing vast amounts of carbon and methane. As permafrost thaws due to climate change, it releases these greenhouse gases into the atmosphere, contributing to global warming and further accelerating climate change.
