Runny noses and itchy eyes – a sure sign of spring in Wyoming for those with seasonal allergies. Tree pollen counts have been in the "high" category in areas below the snow line for the last couple of weeks. Maples, poplars and junipers are the main culprits. Dr. Amanda Staudt, climate scientist with the National Wildlife Federation, says the mild winter means spring allergies will play out longer than usual.
Staudt says the changing climate is setting up conditions in which more allergy-causing trees could take root.
Staudt predicts the situation could be even worse for those with fall allergies. She says the conditions are ripe for a record crop of ragweed, a common allergen, later in the year.
