Sea floor sediments of the Arctic Ocean can reveal how permafrost responds to climate warming. Researchers have found evidence of past permafrost thawing during climate warming events at the end of the last ice age. Their findings caution about what could happen in the near future: Arctic warming by only a few degrees Celsius may trigger massive permafrost thawing, coastal erosion, and the release of greenhouse gases. https://www.sciencedaily.com/releases/2020/10/201016143056.htm
