A climate hazard is a potentially damaging physical event such as flooding, extreme heat, wind, drought, or wildfire that could negatively affect people, infrastructure, or ecosystems.
An infrastructure operator assessing climate risk for a railway line needs to understand exposure to multiple hazards including flood depth, wildfire likelihood, and high-wind events. Each hazard is modelled separately in EarthScan.
Hazards are one of the three pillars of climate risk, alongside exposure and vulnerability. Understanding which hazards are most relevant, and where they occur, is essential for planning and reporting.
