Climate change is making allergy season more miserable- study
A bee collects pollen from a flower. If you’ve experienced extended seasonal allergies lately, you’re not alone. The pollen season in North America is starting earlier and lasting longer than it did four decades ago, a study led by the University of Utah School of Biological Sciences found.
The findings, which were published in the Proceedings of the National Academy of Sciences (PNAS), show that pollen season starts 20 days earlier, is 10 days longer, and features 21% more pollen than in 1990. Climate change is responsible for nearly half of these changes, the study says.
“The strong link between warmer weather and pollen seasons provides a crystal-clear example of how climate change is already affecting people’s health across the US,” said lead researcher William Anderegg.
Airborne pollen allergies can cause more than just sneezing and a runny nose for many each spring. Allergies are tied to respiratory health, with a connection to viral infections. More pollen, hanging around for a longer season, makes the season even more miserable for those with allergies.
Researchers gathered measurements between 1990 and 2018 from 60 pollen count stations across the US and Canada, maintained by the National Allergy Bureau. A bee collects pollen from cherry blossom […]
