A recent study highlights that climate change is causing longer and more intense pollen seasons, significantly impacting hay fever sufferers. Researchers, including medical student Alisha Pershad, analyzed various studies showing that rising global temperatures have already lengthened the pollen season in North America by 20 days between 1990 and 2018. Predictions indicate even more severe changes, with pollen seasons commencing up to 40 days earlier and persisting up to 19 days longer by the century's end. This trend is contributing to increased rates of allergy symptoms and affecting people's daily lives.
"As global temperatures rise due to climate change, pollen seasons are lengthening, starting earlier and ending later, adversely impacting patients' quality of life."
"The review in The Laryngoscope reveals that pollen season in North America has lengthened by 20 days from 1990 to 2018, with projections showing even longer seasons in the future."
