I'm going to highlight this paragraph:

It's worth saying, too, as many headlines point out, that meeting our target temperature of +1.5°C means we still lose the Greenland and Antarctic ice sheets. We should hope for this target, even if it's all but impossible, because it's certainly better than the alternative. But, as I've made clear, I don't think it's gonna happen.

A billion people live in areas 40 ft or less above sea level, areas that will be flooded when - not if, WHEN - the Greenland and Antarctic ice sheets go. A billion climate refugees. That's not a "possibility". That's inevitable even in the best case scenario of 1.5 C. The most likely scenario - 3 to 4 C by 2100 - is exponentially worse.

Solarpunk is about radical hope. Plenty of the visions for a solarpunk future are unlikely or improbable. But none of those visions should be impossible.

A future where the seas don't rise? That's impossible.

A future where we slow the rising seas through both individual and collective action, prepare global civilization for the oncoming crisis with love, unity, and respect for every single person's basic humanity, and end capitalism? That's still worth fighting for.
