In Climate Change: Permafrost and Release of Methane and Carbon, discover the science behind permafrost and its crucial role in the global climate system. Permafrost, the frozen ground found primarily in the Arctic, has acted as a natural storage system for carbon and methane gases for thousands of years. These gases, which were once trapped beneath the surface, are released as the permafrost thaws due to rising global temperatures. This video is excerpted from BBC’s Climate Change — The Facts, a documentary that delves into the science of climate change and its far-reaching consequences.
