Wildfire Risk
Definition
Wildfire risk combines the probability of fire ignition and spread with the exposure and vulnerability of people, assets and ecosystems. Fire weather indices such as the Canadian Forest Fire Weather Index integrate temperature, humidity, wind and precipitation to rate danger; longer fire seasons and extreme fire weather are linked to climate change.

Overview
How it is used
Fire agencies issue danger ratings and restrictions; property insurers price and sometimes withdraw coverage in high-risk zones; disclosure frameworks such as TCFD treat wildfire as a physical risk; utilities manage ignition risk through grid hardening and shutoffs.
Why it matters
Wildfires cause direct loss of life and assets, severe air pollution, carbon emissions and ecosystem damage, with costs rising steeply under warming.
