“2020 was one of the two warmest years on record, tied only with 2016.
According to the European Union’s Copernicus Climate Change Service, in 2020, average temperatures globally were 2.7 degrees Fahrenheit (1.25 degrees Celsius) warmer than preindustrial levels — the point at which scientists agree that human activity, and particularly the burning of fossil fuels, began to accelerate global warming.
In nearly every way, 2020 was a record year for climate-related disasters.
The impacts of the record heat have been felt both around the globe and in the United States. Historic wildfires burned in California, Colorado, Australia, and the Amazonian rainforest. The Atlantic hurricane season produced a record 30 named storms.
Swarms of crop-destroying locusts invaded East Africa, causing devastation to a region already struggling with food insecurity. The Arctic, the area that is currently warming faster than any other place on the planet, saw record declines in ice cover as well as records for how late in the year the ice actually froze.
Even more troubling, 2020’s high temperatures occurred despite the absence of an El Niño event, which typically has the effect of warming the globe; 2016, the other warmest year on record, had an El Niño.”
