Well a good start would be to try to predict agriculture outputs with those temperature. Honestly I tried asking this question but got no answer. Cereals might be just fine, and growing food in places where it's not possible to grow food is also a solution. But I'm terribly curious about the impact on food. Heatwaves will probably cause a lot of deaths at first, but once it happens, there are easy things cities can do to mitigate them.
