The map above, based on a new analysis from the Climate Impact Lab, shows how 95-degree days (35 degrees Celsius) are expected to multiply this century if countries take moderate climate action. In this scenario, countries would take some measures, but not drastic ones, to curb emissions — roughly the trajectory of the current pledges under the Paris climate agreement.
The resulting global warming would still cause significant shifts for many cities. In Washington, from 1986 to 2005, an average of seven days each year had temperatures of at least 95 degrees. By the end of the century, the city can expect 29 of these extremely hot days per year, on average. (The likely range is 14 to 46 hot days per year.)

Good analysis on what the impacts of the hotter days coming are going to be. 95 F is as reasonable an arbitrary measuring point as anything else, we’re approaching body temperature there. The article looks at the world under the Paris agreement, as well as without it. The differences are striking.
Interestingly, commercial crop yields (specifically corn and soybeans) start to drop after 84 F. I hadn’t realized that, but it makes sense. That’s how hotter days, even without drought, have negative impacts on our food supply.
