I live in Colorado and ride my bike up in the mountains every week. As always, there are some patches of dead trees from forest fires, disease, bark beetles etc. I also worked two summers as a wilderness ranger for the USFS thirty years ago, and I don’t see anything alarming going on in the forests. Overall, they are as healthy as they have ever been.
Yet we have this bizarre subculture of “experts” who have convinced themselves that the forests are doomed and falling apart. The only thing I can figure is that they have no sense or awareness of history. Cycles of drought, fire and disease are a normal and essential part of the forest ecosystem. It is called “natural selection.”
Gore says that four million acres of forest has been lost to pine park beetles over the last 15 years. Put in perspective, that much forest was lost to fire during one week in Wisconsin 140 years ago, when CO2 was 290 ppm.
