In short, we aren’t on track to an apocalyptic extinction, and the new head is concerned that rhetoric that we are is making people apathetic and paralyzes them from making beneficial actions.
He makes it clear too that this doesn’t mean things are perfectly fine. The world is becoming and will be more dangerous with respect to climate. We’re going to still have serious problems to deal with. The problems just aren’t insurmountable and extinction level.
If there is one fire that set the entire Amazon on fire, that wouldn’t be a big deal because it’s only one fire?
The whole point is the severity of fires due to climate change has made it so we’re fucked. As you’ve said, the same number of fires are occurring, they are just significantly worse. I would argue that 3 small fires in a fairly wet forest that goes out relatively quickly is favorable to 3 enormous fires that burn a significant percentage of a forest over several weeks due to that forest being dried out (caused by climate change). Your position seems to be “well, it’s the same amount of fires, so it’s not climate change.” It doesn’t make any sense.
