There is not much room for optimization left. Best solar cells get close to 23% efficiency, apparently the current theoretical maximum is a little over 30%.
Well, the most dramatic scenary is that everyone is going to die. So, yes, we will avoid that.
But realistically, I think we wojt do 1,5C, but are going to have more like 2,5-3C. So horrible, but still survivable for at least half of the humans now.
I know this is not a thread where one says a superpower and the other a side effect. But how about: "the pencil which comes out of your finger break very often, and to sharpen it you have to spin your whole body 360 degrees a couple of time" , just like a normal pencil sharpener.
No? And what does that have to do with the conversation?
