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.
Yeah, I don’t see what he’s getting at. There has absolutely been alarmist rhetoric surrounding climate change, and I see it all the time. Hell, I’ve seen people who think we’re already too late, even if we were to stop releasing CO2 today itself.
Part of me wonders how much the other side has benefitted from the sense of apathy this could create. After all, there’s real value in making stupid people give up entirely, in some ‘we’re doomed’ scenario.
