The flames left the redwood trees charred, but still mostly alive. The rest of

the life that usually animates the forest was gone. You can hear it in the silence. There's always

been a fire season in California in the late summer and fall, but recently it's gotten longer,

and worse, much worse.

There's no denying climate change here.

2022 has been another year of drought for the American West, and that means that until the winter rains come in force, there's still a risk for fire.

California forests burned frequently until about 100 years ago when across the west a new

approach to fire emerged in the name of conservation, suppression, as in fire was bad, a destructive

force to be avoided at all costs. But research into thousands of years of climate history has shown that fire has always been a part
