Forest Fire
Forest fires can destroy buildings and infrastructure through direct flame, intense radiant heat or ember attack.
Grass fires are also a potential risk but are not currently covered by Climate Valuation's analysis.

Effects of Climate Change on Forest Fire

One of the clearest findings of climate science is that global warming amplifies the intensity, duration and frequency of heat waves, drought, and wildfires.
Increased Heat
Our planet's atmosphere and oceans are heating up ten times faster than anytime in the last 65 million years, leading to more extreme heat days.
Dryer Conditions
A warmer atmosphere draws more water from the soil, increasing the likelihood for drought conditions in some regions which increases the probability of fire ignition.
Stronger Winds
Climate change has an impact on wind speeds. In less than a decade, the global average wind speed has increased from about 7 mph to about 7.4 mph. Stronger winds create conditions for fires to burn hotter and faster.

Contextual Data

The driving parameters of forest fire are temperature, humidity, wind speeds and forest fire-prone land. The forest fire hazard layers in the Climate Risk Engines use satellite data in conjunction with algorithms to account for local conditions.
Tree Density
Tree density impacts the amount of fuel available for forest fires.
Temperature & Humidity
Hotter and dryer conditions lead to higher rates of combustion.
Wind Speed
Wind speed has a significant effect on the spread of fires.

Asset Data

The exposure of a property to a forest fire is defined by the building's construction elements (e.g. roof, walls, floor). Different materials have different combustion thresholds. Therefore properties built from fire resistant materials such as brick or stone will have lower vulnerability to forest fire than those built with timber or plaster.

The Climate Valuation analysis takes into consideration the property's specific design and construction materials, providing more accurate insights into its probability of combustion. Variable information that might impact a property's vulnerability (e.g. how often the gutters of a house in a fire zone are cleaned), may not be practically available or estimable.
