Caused by Gorbal Walming, at least that what Gov. Moonbeam says.
I think the fires were started intentionally to bring up Glowbull Warming as the cause. But they got out of hand.
I always thought it was Gerbil Warming, in honor of Richard Gere.
The only thing more ignorant then Moonbeam is his followers. I'm from East Tennessee. But I have enough common sense to understand that an area averaging less then 20 inches of rain per year, with a very low humidity, and lots of fuel for fires meaning anything from vegetation to structures, will burn fast if they catch fire. The region is a tinderbox. It always has been. The developers built cities in a semi desert environment.
To make it safer and liveable the state is going to have to re-think fire prevention and fire fighting. That will mean money. It takes water. Why not ocean water piped through a dedicated piping system ran on top of these mountains and staged high capacity storage tanks with high capacity nozzles piped to different locations down hill for coverage to be activated when needed? That is no more an insane idea then the states arcane environmental laws and the money wasted on those policies.
