As I sit here dying from a ferocious onslaught of springtime allergens, I have to wonder if increasing global temperatures can be linked to increased allergies.
Well, according to the nonprofit organization American Forests the answer is yes:
Studies suggest that higher levels of carbon dioxide and warmer temperatures may increase pollen production, making allergies worse. Tree planting is one of the best ways to reduce the amount of CO2 in the air.
Apparently there is a scale called OPALS (the Orgen Plant-Allergies Scale) which rates every plant on a 1-10 allergic scale (based on each plant's pollen count and potency level). American Forests will only be planting trees with a rating of 5 or less.
