I also think we keep going which is the only thing anyone can do when there is no way to stop. I mean we can't just say this or that won't work so let's just forget the whole thing and stop trying.
On the other hand let's remember that projections are based on us remaining just as stupid as we are now for another couple of decades without getting smarter! I think though that as time goes on we will continue to smarten up.
People know about climate change now. Innovations and new technologies are being created. 20 years from now we may have invented an effective carbon scrubbing technology that may reduce atmospheric carbon.
The first and most critical step has been successfully reached. The climate change deniers LOST. The world knows it is real. Now we all can focus on fixing the problem. 10 years ago most people were skeptical or denying climate change but that foolishness has ended.
Have some hope ...human beings are messy but we are survivors.
I have less hope for Earth's biological diversity.
We were fools more foolish than any fools have ever been to have lost so much for so little reason.
