Answer:
We can break "climate hazard" down into two distinct words.
Climate: the prevailing weather conditions of a region, as temperature, air pressure, humidity, etc. throughout the year, averaged over a series of years.
Hazard: A source of danger.
A climate hazard is a physical climate-induced event that can put people, animals, and natural resources at risk.
Examples range from rain, to tornadoes, to climate change.
