Seasonal Allergies Intensify Across the U.S. Due to Climate Change

The warmest winter on record and a 21% increase in pollen since 1990 contribute to longer and more severe allergy seasons.

Climate change is worsening seasonal allergy symptoms, causing earlier and more intense pollen seasons across the U.S.
The warmest winter on record in the continental U.S. has led to plants blooming earlier, contributing to a 21% increase in pollen since 1990.
Cities like Wichita, Kansas, and Virginia Beach, Virginia, are among the most challenging for allergy sufferers due to high pollen counts and limited allergy specialists.
Over-the-counter remedies and reducing exposure to pollen are recommended for managing allergy symptoms.
While some U.S. cities have seen longer allergy seasons, a few, like Ottumwa, Iowa, have experienced shorter seasons due to unclear local impacts of global warming.
