The National Oceanic and Atmospheric Administration warns in a stark new report that greenhouse gas emissions have radically transformed the Arctic in just the last 15 years. The 2020 Arctic Report Card warns of dwindling sea ice, accelerating Arctic wildfires, summertime temperatures topping 100 degrees Fahrenheit, and rapidly melting permafrost that’s releasing vast quantities of heat-trapping methane gas. On the whole, the Arctic is warming three times faster than the rest of the globe.
