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.
Dude - I’m really sorry, an escape hatch for the rich people who can pay to be onboard isn’t a solution. We’ve been living unsustainably - this, by definition, can’t be sustained. We need to change now so we can make that change as comfortable and human as possible; otherwise we’re going to be stuck reactively responding to each successive disaster, or crop failure, or ecosystem collapse, or climate migration wave etc.
We need to get ahead, now.
Human expansion into space is anything but that and the idea that it is is just meaningless capitalist propaganda. Human expansion into space consists of:
Building space solar power stations (SSPSes) to beam power down to the Earth 24/7 to replace the coal plants
Mining calcium and magnesium from the Moon and near-Earth asteroids (NEAs) to bind with the excess CO2 in th oceans to stop and reverse ocean acidification
Mining rare-Earth elements from NEAs to mass-produce electric cars and batteries down here ln Earth to replace gas vehicles
Build O’Neill cylinders to preserve and rebuild ecosystems in safe places where poachers will never be able to reach
Among other things.
