A Decade of California Wildfires

A bar graph displaying the number of acres burned each year in California from 2011 through 2021 (as of 10/13/2021). The graph shows a clear increasing trend in number of acres burned since 2011, with 2020 being the highest year, more than doubling any previous year's number.

Acres burned in California wildfires have shown an increasing trend over the past decade. 2020 had double the acres burned of any previous year over the past decade. 2021 is already over halfway to equaling 2020’s numbers, and it’s only mid-September.
