> what are you still talking about, it's done

It's not. The climate will warm as much as we emit CO2. Sure, the CO2 that we have already emitted won't leave. We've passed 1.5C, that won't come back in our lifetime. But the more we emit, the worse it will get. To keep what we have now, we have to stop emitting entirely, right now.

> We now need to worry about the hundreds of millions of people

We need to worry about the problems that are coming from the CO2 we have already emitted, that's true. But we also need to worry a lot about the fact that we are making it worse every single day. We are not reducing our CO2 emissions, we are increasing them right now.

Are you worried about hundreds of millions of refugees? The way it's going, we'll reach 4C. It means that billions of people will have to move.

I don't think we can still use the concept of "refugee" when its entire countries that need to move because their part of the world has become so hot that humans cannot survive outside without life support (that's what will happen to billions of people with 4C). At this point, it's entire countries moving with their military, it's just global war.

hundreds of millions of people coming to europe (i didn't mention) is still lowballing on purpose. sure it's billions, but not all will go to one place was my thinking here.

you are talking reason, you are in the wrong timeline buddy. i'm talking about what we will chose as a society, i feel we can't help ourselves.

You can convince a person (me certainly) that we should stop immediately (or very very short time frame). But most people have experienced their entire lifetime of propaganda and fallacious arguments that words and reason have lost all meaning.

We are still getting cooked so slowly that people will only see unrelated incidents for a long time. World War(s) 3 is what the survivors will call it.
