This paper examines the temperature-mortality relationship over the course of the 20th century US both for its own interest and to identify potentially useful adaptations for coming decades. There are three primary findings. First, the mortality impact of days with mean temperature exceeding 80° F declined by 75%. Almost the entire decline occurred after 1960. Second, the diffusion of residential air conditioning (AC) explains essentially the entire decline in hot day related fatalities. Third, using Dubin-McFadden’s discrete-continuous model, the present value of US consumer surplus from the introduction of residential AC is estimated to be $85 to $188 billion ($2012).
