Climate change has already extended the duration and severity of allergy season and will increase pollen emissions by as much as 40 percent in the United States over the coming decades, a new study concludes.⁠

As global temperatures continue to rise because of excess greenhouse gases in the atmosphere, plants are producing more pollen, the study conducted by researchers at the University of Michigan and published ⁠Tuesday in Nature Communications concludes.⁠

“Temperature impacts the number of winter chill hours and spring frost-free days and is strongly associated with the timing of pollen seasons, including the start date, peak emission date, end date, and duration,” the study states.⁠

By the year 2100, the start-of-spring pollen emissions will begin 10-40 days earlier, while the growing season for summer and fall weeds and grasses will extend five-to-15 days later, according to the study.⁠
Unless human beings set about curbing air pollution, limiting greenhouse gas emissions and slowing the rise in global temperatures, the annual increase in pollen emissions worldwide could top 250 percent by the end of the century, the study concludes.⁠

While the latest calculations put a fine point on how bad allergy season could become due to climate change, the link between the two is long established. On its website the Centers for Disease Control and Prevention notes that allergies represent a serious public health threat.⁠
