It's basically a year to a year and a half off people's life expectancies, from the heat alone.
Although this is not trivial, the antivaxxer movement will likely chop 10-15 years off life expectancies and greatly reduce quality of life for much of the remainder, same again for the expected massive reduction in air quality that will result from modern political movements, and the absurd puritanical movement in the US will likely chop another 10-15 years off the life expectancies of women.
These are, therefore, substantially more significant, although politically impossible to deal with right now.
I fully expect that, if current trends prevail, by 2040, life expectancies will resemble those of the Neolithic and Bronze Ages.
