2020's global average temperature tied 2016 as the warmest year on record.
With the temperature being 1.02 degrees Celsius above the 1951-80 baseline, these findings demonstrate a continuation of the Earth's long-term warming trend. Data from @NASA .
Wildfires in the Arctic Circle emitted a record 244 megatons of carbon dioxide last summer.
As more of the Arctic's carbon-rich soils thaw or burn, more carbon is released, creating a positive feedback loop that further warms the atmosphere. Data from @nature.
