| Description: |
Permafrost or frozen ground, which contain about 1,700 gigatons of carbon in the form of frozen organic matter, have begun to thaw in response to Arctic warming over the past few decades. Greenhouse gas emissions from thawing Arctic permafrost could result in an additional $43 trillion in economic impacts by the end of the twenty-second century, according to a new study. These extra impacts justify the need for urgent action to reduce emissions from thawing permafrost. [Source: National Snow and Ice Data Center]
