Right. There is a "too late" to prevent any catastrophic climate change, and we're well beyond that. But there is no "too late" to making it less bad than it will be assuming we don't do something.
The plane is going down. We still have some control, and we can aim for a softer landing, but everyone needs to assume the crash position and stop pretending we didn't cause a crash.
Yes, because those 0.05K might be the difference between certain disasters occurring or not. Certain disasters are so bad that we lose control over temperature because of something feedback loops.
We are already in feedback loop territory. The fact this is missed by so many people used to fill me with dread, but I've since learned to (cope by) accept reality. You can lead a horse to the water, but you can't make it drink.
Well, we can achieve much better than either of those two if there's political will. But given 3.95C or 4C I know which I'd pick, and aren't many western conveniences I wouldn't trade for even that small improvement.
While I believe this is absolutely true, there is also a very real point we have seen in virtually all of our studies where we're fucked pretty much no matter what. It's just a matter of how fucked at a certain point. But I guess that's the sentiment being expressed here, just much more gently.
