Maps using data on ozone pollution, ragweed and “extreme heat days” in the United States show California to be an especially vulnerable place.

The number of unhealthy days in Los Angeles, in particular, is expected to rise in the coming years due to a combination of rising temperatures from climate change, droughts, flooding and pollution.

Research shows that rising temperatures can worsen the negative health impacts of pollution and ragweed on respiratory illnesses such as asthma.

 

Los Angeles has smog and ragweed pollen problems and is at risk for at least one unhealthy air quality day per summer, meaning the air does not meet the U.S. Environmental Protection Agency’s standard for ground-level ozone. Smog intermixed with pollen poses a dual threat to the health of people with allergies and asthma.
