Understanding Regional Climate Trends and Their Impact on Pollen Seasons in the U.S.

Climate change is significantly impacting pollen seasons across the United States, leading to longer and more intense allergy periods. This phenomenon is primarily driven by warming temperatures, resulting in extended growing seasons and increased pollen production.
How Are Pollen Seasons Changing?
Research indicates that since 1970, the freeze-free growing season has lengthened in 87% of 198 U.S. cities analyzed, with an average increase of 21 days. This extension provides plants with more time to grow and release pollen, leading to earlier and prolonged allergy seasons. (climatecentral.org)
