Climate Change and Allergies 

The impact of climate change has become a dangerous cycle. Rising global temperatures lead to more extreme weather. Weather changes – such as heat waves and droughts – can lead to a lack of air flow. When the air doesn’t move, pollutants react together in the heat and sun. This increases ground-level ozone.1 

Ground-level ozone is a major part of urban smog. More air pollution and smog cause higher levels of carbon dioxide (CO­­2). This results in warmer temperatures. And the cycle continues. 

This cycle results in increased pollen. This can trigger asthma and allergy symptoms. Rising CO2 levels lead to longer growing seasons that change flowering time and increase pollen. The length of the growing season refers to the number of days when plant growth takes place. Warmer, longer seasons increase exposure to allergens that trigger asthma and other respiratory and allergic responses.2 

Climate change is also impacting the health of people who live in urban centers. Warmer temperatures and extreme heat waves are made worse in urban areas due to an effect called an “urban heat island” (UHI). A UHI has higher temperatures than surrounding rural areas due to more buildings, roads, population, and lack of green space. Extreme heat made worse by UHIs can increase air pollution and allergic sensitivity.3 Climate change will make these UHIs worse. Black and Hispanic Americans − who already have higher rates of asthma and allergies − will be affected the most by worsening UHIs due to a long history of discrimination in U.S. housing policies.
