(Reuters) – Climate change could push the cost of U.S. allergies and asthma beyond the current $32 billion annual price tag, conservation and health groups reported on Wednesday.
A warming planet makes for longer growing seasons that would produce more allergy-provoking pollen in much of the heavily populated eastern two-thirds of the United States, the National Wildlife Federation and the Asthma and Allergy Foundation of America said in their report.
The cost of coping with allergies and allergen-driven asthma in the United States is at $32 billion in direct medical costs, lost work days and lower productivity, the report said.
“Climate change could allow highly allergenic trees like oaks and hickories to start replacing pines, spruces and firs that generally don’t cause allergies, exposing many more people to springtime allergy triggers,” said Amanda Staudt, a climate scientist at the wildlife federation.
