That's a fair point. I did start digging into the climate-change impacts literature to qualify this some bit more, but frankly it became a bit overwhelming, both in the number of articles which you need to try and summarise, and the emotional strain reading the impacts places on you. I think an interesting article would be looking at what might survive 4-5 degrees of warming. But in this article I wanted to avoid turning people off reading by simply listing all the bad things that may happen, and allow a focus on the psychology.
