We estimate that around 700 annual heat-related deaths during 1961–1980 were masked by the cooling effects of aerosols. There was a sharp increase in heat-deaths between 1980 and 2020 due to the combined effects of greenhouse gas increases and large aerosol reductions.

We found a growing evidence base describing the use of implementation science in health system responses to pandemics (n=54 studies), but a dearth of similar evidence for climate change (n=2 studies).
