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.
While I understand the intention here is to reassure people that not all is lost and there’s still time for action, a take like this is going to be paraphrased into “climate change is overblown and isn’t something to worry about” by Big Oil and other major polluters.
I have not seen a single piece of evidence that we’re going to do anything about climate change unless we come up with some magical solution that somehow: doesn’t upset the status quo and also makes existing rich people even more rich.
The status quo is the problem, so it would have to be some basic logic defying magic.
