We have too much “bad fire.” Not only destructive wildfires, but the combustion that powers our automobiles and provides our electricity has generated a worrying rise in atmospheric carbon dioxide. And that is driving climate change which is adding to the frequency of megafires. Now we’re seeing those effects in “fire-clouds,” pyrocumulonimbus events. But there’s such a thing as “good fire.” Indigenous peoples managed the land with controlled fires, reaped the benefits of doing so, and they’re bringing them back. So after millions of years of controlling fire, is it time for us to revisit our attitudes and policies, not just with regard to combustion, but how we manage our wildfires?
