$19 Billion USD and almost two decades of cutting carbon emissions were erased in California’s 2020 fire season.

Researchers at UCLA and the University of Chicago estimated that about 127 million metric tons of carbon dioxide equivalent were released by the California fires in 2020, compared with about 65 million metric tons of reductions achieved in the previous 18 years.
The researchers contend that wildfire emissions or “natural emissions” should also be considered as a major contributor to greenhouse gases when planning reduction goals.
