Before areas become completely uninhabitable, we will see areas become increasingly stressed: heat waves, more extreme weather events, poorer crop yields, depleting aquifers.

Stress increases conflict risk. Fights for essential resources (land, water, food, shelter) will break out long before those essential resources are completely gone.

If we skip past the immense suffering and death part, we will probably end up on a planet where national borders have been redrawn by war and desperation, and a smaller population that lives in more northerly climes.

Our politicians are already thinking about them, which is why they are cracking down on immigration and generating relentless propaganda demonizing refugees and asylum seekers.

It's going to happen, so that's exactly what we should be prepared for.

I'm sad all ocean megafauna are going to be extinct.

Are you sure the whole world won't become completely uninhabitable? It's not like we have a trial earth to test this out on.

Perhaps they are part of the depopulation agenda.
