I acknowledge that CO2 contributes to fertilisation. I was refuting the claim about the saharan desert. Your new link doesn't seem to contradict me :
> CO2 fertilization effects explain most of the greening trends in the tropics
- nwah1 8y agoYes, I accept your correction. I accept that the Saharan desert may be greening primarily for other reasons. It seems to have been on a long term trend towards greening irrespective of the Industrial Revolution, and there are other human activities that are greening it. Although, your link does leave open the possibility that rising CO2 explains up to 22% of the greening in the Sahara.
