Heat summary of Chapter 10

Hotter and drier summers, projected as part of climate change, create ideal conditions for wildfires. A 2°C increase in global temperatures could double the days in the UK with very high fire danger and extend the wildfire season into late summer and autumn. This was evidenced by the unprecedented number of wildfires during the UK’s heatwave in the summer of 2022, particularly in urban areas like London.

Wildfires pose multiple health risks, including injuries, respiratory and cardiovascular effects from smoke exposure, and mental health issues. Smoke from wildfires can degrade air quality significantly, leading to increased air pollution-related mortality.

Wildfires may coincide with other extreme weather events like heatwaves and droughts, creating complex health challenges. These events may increase demands upon health and care services.

The likelihood of larger, more severe wildfires is expected to grow with climate change. This includes not only rural but also urban areas that are not traditionally prone to such events, increasing the risk to public health.

Climate adaptation strategies should consider how to help communities prepare for, respond to and recover from wildfires. This includes considering compound impacts from simultaneous extreme weather events and improving public awareness of the risks associated with wildfires.
