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, any solution to climate change that relies on people of good faith coming together across national boundaries to solve our global problems is a bunch of pie-in-the-sky horseshit and most definitely not something to pin the future of humanity on.
The only thing that’s actually going to reduce greenhouse emissions is cost savings; focus on that, build your models around what we can convince people to do with that, then figure out how to save as much of the human race and the natural world as possible in a scenario where we do fuck-all about climate change except when by doing so it makes some rich asshole slightly richer.
