Climate change isn’t just contributing to drought, super-storms, sea level rise and flooding. It’s also making it harder for many people to breathe, like 13-year-old Estefany Velasquez. Her family faced a tough choice because of her asthma.  

More than 24 million Americans have asthma.

Rising temperatures and changing rainfall patterns can lead to longer growing seasons and higher pollen counts, all of which can worsen asthma symptoms.

“Those are all expected to contribute to increases in some of the signs of airborne allergens that can trigger an asthma attack,” said Kim Knowlton, assistant professor in the climate and health program at Columbia University.

With climate change we’re also seeing more intense wildfires across the west, and in recent years, scientists have correlated those bad smoke days with an increase in emergency room visits for people with respiratory diseases.

Asthma rates are on the rise nationally and health experts and scientists expect to see that trend continue in the coming years as the effects of climate change take hold.
