Yes, OP and his post are talking about the death toll and extinction, I replied in kind.

Changes in the climate might decrease yields, however CO2 concentration directly increases them. This should recover 60 to 110% (net gain for wheat) of the losses due to climate change depending on the crop from 2000-2080 according to NASA.
