Catching Fire

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?

100 Seconds to Midnight

On the famous clock-face of the Bulletin of Atomic Scientists, the time now is 100 seconds before midnight. Meaning: humankind is closer to nuclear doomsday than it’s ever been. But it’s worse than that: those educated alarmists at the Bulletin advanced the second-hand on their clock before Russia’s invasion of Ukraine in February. It’s a fiasco now, in mid-May: we can see a Russian autocrat with a taste for cruel and crushing force, facing humiliation and huge losses, but holding an arsenal of 4,500 nuclear warheads, which he says he could use. Stranger still: one in three Americans favor US military action in support of Ukraine, “even if it risks a nuclear conflict with Russia.” Are we scared yet? What if we’re not scared half enough?
