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.
Problem is that climate change is political. Worse, it’s geopolitical. It’ll take the will of the people to just tell governments to stop plodding along doing the bare minimum and take some real action for once.
What’s happening right now is terrible, but it’s also a chance to wake up the masses in time. I just hope the impetus isn’t lost to apathy.
