I'm in the United States. Conservatives are currently pivoting to their new "climate change is inevitable, and therefore we must seal our borders to protect America from climate migrants and give more subsidies to big corporations and fossil fuel companies whose technology will maintain our standard of living" talking point.

The more people panic about climate change, the more persuasive that argument becomes.

Human rights are one of the first things to vanish in disasters. When people are scared, they agree to give up their rights. When people are scared, they close their eyes as the government violates other people's rights.

And the more frightened people are about climate change, the more they'll turn to authoritarian demagogues who promise them safety.

Hope is vital. Because once people give up hope of saving the planet, all that's left is an ever more vicious scramble for ever fewer resources. And once you decide that's an inevitability, the only logical thing to do is get vicious as fast as possible.
