Wildfire risks to people include death and destruction of their homes, respiratory illnesses from smoke , post-fire flooding from areas exposed by vegetation loss and degraded water quality due to increased sediment flow  and the chemical precursors of carcinogenic trihalomethanes when water is later chlorinated for drinking  . Under RCP8.5 and shared socioeconomic pathway SSP3 , the number of people living in fire-prone areas could increase by three-quarters to 720 million in 2100, in a projected global population of 12.4 billion people . Lower emissions under RCP4.5 could reduce the number of people at risk by 70 million. In these projections, human population growth increases human exposure to wildfires more than increases in burned area . A global temperature increase <2°℃ could increase global population exposure to wildfire by ~30% . Increased wildfire under continued climate change increases the probability of human exposure to fire and risks to public health .
