New Study: Heatwave-Related Deaths Have Been Declining In Recent Decades
By Kenneth Richard on 4. August 2025
Human ingenuity outpaces modern warming.
A comprehensive new data analysis (Walkowiak et al., 2025) involving European countries finds it takes less than 18 years for humans to adapt to a 1°C increase in mean annual temperature. Consequently, exposure to excessive heat has become less and less deadly.
Supporting this conclusion, a 2018 study involving 305 locations across 10 countries (1985-2012) affirmed “a decrease in heat-mortality impacts over the past decades,” as “heat-related mortality [fractions, AFs] decreased in all countries.”
Many heatwave or excess heat mortality studies fail to account for the human capacity to adapt to extremely hot temperatures via the expansion of access to air conditioning, heat-shielding structures and building materials, etc.
This (intentional?) failure artificially inflates modern heat exposure risks so as to make it appear heat wave mortality has become more and more of a problem.
The real risk is cold exposure. Since the 1980s humans have been 20 times more likely to die from exposure to excessively cold temperatures than to excessive heat.
