Climate for humans
Hi foolmeonce,
The authors chose the period 1951-1980 because it was during a time of climate suitable for human life. They said this in the study -- I didn't mention it because when most people talk about mitigating climate change, they mean so that the climate stays acceptable to human life. I chose not to state what I thought was obvious. While the planet can withstand any climate -- one fit for dinosaurs or one fit for us -- we're a bit fussier.
