Standards for Official Statistics on Climate-Health Interactions (SOSCHI): Methodology: Suicides attributable to extreme heat

Climate change is leading to more frequent and extreme climate-related hazards that influence mental health outcomes. Direct impacts on mental health can arise from increased exposure to extreme temperatures and extreme weather events. Indirect impacts can be due to displacement, malnutrition, conflict, climate-related economic and social losses, along with anxiety and distress associated with worry about climate change.

This topic area aims to quantify the mental health impacts, currently focused on suicides attributable to extreme temperatures.

This is the Methodology document for indicator: suicides attributed to extreme heat.
