As you likely know, the pollution that comes out of tailpipes and smokestacks contributes to climate change, which increases the probability of extreme flooding, intense storms, and heat waves. Dr. Perera’s article points to such a heat wave in California in 2006, where 2,500 children were admitted to emergency rooms. And, as a study recently reported, the number of record-breaking heat events is roughly 5 times higher than expected in a climate with no long-term warming. Even the recent Zika virus epidemic may be linked to climate change, where warmer temperatures increase the rate at which mosquitoes bite and increase the geographical range o mosquito habitat.
