You are welcome! The deaths from non-optimal temperature plotted above are supposed to cover all causes of death, including from food shortages (although these might account for a much larger fraction of the deaths from non-optimal temperature for abrupt variations of temperature). There were 1.91 M deaths from non-optimal temperature in 2021, 53.1 (= 1.91*10^6/(36.0*10^3)) times the 36.0 k deaths from environmental heat and cold exposure. From Our World in Data (OWID):
Think about someone dying from extreme temperatures. You probably pictured someone passing out from heat stroke or dying from hypothermia.
But this is not how most people die from “heat”. They die from conditions such as cardiovascular or kidney disease, respiratory infections, or diabetes.
