Human-caused climate change to blame for increase in California’s wildfires

In the quarter century between 1996 and 2020, wildfires in California consumed five times more area than they did from 1971 to 1995. Researchers at the University of California and other international institutions have concluded that nearly all of the increase in scorched terrain can be blamed on human-caused climate change.

Greenhouse gas and aerosol emissions are lengthening and intensifying droughts

Irvine, Calif., May 17, 2021 — Greenhouse gases and aerosol pollution emitted by human activities are responsible for increases in the frequency, intensity and duration of droughts around the world, according to researchers at the University of California, Irvine. In a study published recently in Nature Communications, scientists in UCI’s Department of Civil & Environmental Engineering showed that over the past century, the likelihood of stronger and more long-lasting dry spells grew in the Americas, the Mediterranean, western and southern Africa and eastern Asia.
