Climate Change Is Increasing the Intensity of Allergy Seasons: Study

Climate change is altering our pollen seasons, leading to more severe allergies for a longer duration. A recent study found that this is the case.

University of Michigan climate scientists used computer simulations of 15 US plant pollens in order to predict how severe the allergy season would be by 2100.

Climate change is believed to have already affected our allergy season. As allergists state that the pollen season in America used to begin around St. Patrick’s Day. But, it now starts around Valentine’s Day. According to CBS.

A new study published in Nature Communications shows that allergy season will begin weeks earlier than usual and last for several days longer as the world warms.

The study’s projection is that the pollen levels could potentially triple in some places, making the seasons both harder and longer for those with seasonal allergies, particularly those with asthma. 

Yingxiao Zhang (University of Michigan Climate Researcher) is the lead author of this new study. According to Zhang’s study, pollen allergies can harm the economy by reducing work days and medical costs.

Bill Anderegg, University of Utah biologist and climate researcher, spoke to CBS. “Overall, this is an incredibly important study.”

“It indicates that we are likely to see the same historical trend of longer and more severe seasons for pollen, driven by climate changes. This will certainly have serious health consequences for Americans with allergies and asthma.
