Pollen season has grown longer, more severe over past 30 years
ORLANDO, Fla. – Central Florida’s pollen season has kicked into high gear this year, with the return of spring-like temperatures. This then would mean temperatures strongly influence not only the length of pollen season, but also its intensity. Studying their 60 pollen reporting stations across the country, the pollen season has become 20 days longer compared to what it was 1990. Because pollen concentrations are highly sensitive to temperature and carbon dioxide, this study found that human-caused climate change was responsible for at least half of the additional days of pollen season. These findings concern doctors, as these drastic changes to our pollen season across the country could impact many who suffer from asthma and allergies.
