Abstract The fourth Health Effects of Climate Change in the UK report (HECC) was published by the UK Health Security Agency in 2023. The report brings together 15 independent chapters written by 90 experts from UK and international academic and research institutions and UKHSA. It provides an authoritative summary of the scientific evidence on the health effects of climate change in the UK, potential implications for public health and gaps in evidence. Chapters include a combination of new empirical analyses (using the most updated climate data - UKCP18 projections) and synthesis of new evidence. Topics covered include future UK climate, temperature effects on mortality, flooding, outdoor and indoor air quality, aeroallergens, infectious diseases, vector-borne diseases, food supply, wildfires, drought, human exposure to chemicals, solar radiation, health impacts of net zero and indicators for climate change and public health tracking.
