Hi Ugo, you are one of my saints. But even if you would go to net zero at once The warming would go on because of the many feedbacks already in place, (Water vapour, Methane, Wildfires).

And we are not going to net zero any time soon, On the contrary, Everything is accelerating, And as soon as we have lost the Polar ice all hell will break loose. Therefore, although I'm a physician and very prudent with forecasts I would say that we have not some decades, but Rather some years left. The end will not be decline But rapid destruction of the higher biosphere. That's what we should preparing for. Cheers

Yes…

So will the hoped-for generalization of renewable energy will allow us to preserve most our civilization and, more to the point, keep alive the vast population it supported so far ? Or will it not ?

In the end, one way or an other, it is still more a matter of creed than facts. To the point where it will always be possible to argue that it won't happen if not enough people believe in it...

And still, as far as I'm concerned, I'm very doubtful and tend to think along the same ways than your interlocutor.

But or course, that doesn't mean it's the end of human history.

Actually, it's probably the difference between optimism (the idea that we will find a way to fix our problems) and hope (the idea that not everything is lost and one day the situation can/will improve again).
