Global Change Impacts & Adaptation
A Review of the Impact of Climate Variability and Change on Aeroallergens and Their Associated Effects (Final Report)
EPA announced the release of the final report entitled: A Review of the Impact of Climate Variability and Change on Aeroallergens and their Associated Effects.
This report is a survey of the current state of scientific knowledge of the potential impacts of climate change and climate variability on aeroallergens in the United States -- including the impacts of pollens, molds, and indoor allergens -- and their associated effects on allergenic illnesses.
Since 1998, EPA has been assessing the consequences of global change on weather-related morbidity, on vector- and water-borne diseases, and on airborne allergens and ambient pollutants, especially tropospheric ozone and fine particles. With this completed, this report adds to the increasing body of knowledge on potential effects of global climate change on human health.
- Pollen production is likely to increase in many parts of the U.S. with the possible exception of the Southeast;
- Phenologic advance is likely to occur for numerous species of plants, especially trees;
- There will likely be changes in the distribution of pollen producing species, including the possibility of extinction in some cases;
- Intercontinental dispersal is possible, facilitating the introduction of new aeroallergens into the U.S.; and
- Increases in allergen content of some aeroallergens are possible.
