Allergies will worsen and trigger more asthma attacks if climate changes continues, warns a new report by the National Wildlife Federation.
"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," says lead author Amanda Staudt, a National Wildlife Federation climate scientist, in a statement.
The report identifies nine states as hotspots for large increases in allergenic tree pollen if global warming goes unabated: Arkansas, Iowa, Maine, Minnesota, New Hampshire, New York, Pennsylvania, Vermont and West Virginia.
It says seven more states are at risk for moderate increases in such pollen: Connecticut, Illinois, Kentucky, Massachusetts, Mississippi, Tennessee and Wisconsin.
