> The fact that 2 °C is probably enough to render the space of potentially billions of people uninhabitable is completely outside of the experienced reality in Western countries, we cannot relate from our lived reality to theirs.

Surely they'll reconsider once potentially billions of climate refugees flood countries up north.

Also I think the impact of weather extremes is underestimated. You can reinforce buildings against stronger winds. You can move people into climate-controlled buildings. Desalinate seawater when the rains stop.

But that's impossible for the bulk of agriculture. Now imagine extreme winds, droughts and/or wildfires decimate 1 or more staple crops - worldwide, in a single season. Economic chaos, wars & famine will ensue.

Compound effects are a thing. And there's an ever-growing list of candidates.

>3°C global warming is nuclear-WW3 level.
