What does climate change have to do with allergies?

​Carbon emissions cause warmer temperatures, creating longer growing seasons.  This creates more pollen over longer periods of time.  Burning fossil fuels also causes air pollution that can make allergy symptoms worse. 

 

According to a 2021 study:

  • Pollen counts have been increasing over the last 20+ years in the United States at least in part due to climate change

  • Pollen season is now 20 days longer on average than it was in 1990

 

Another 2015 study found that in 2000, annual pollen production began on April 14 and peaked on May 1, but that in 2040, pollen levels are predicted to peak as early as April 8.

How can I protect children in worsening allergy seasons?

Here are some steps you can take to reduce children’s exposures to pollen and other allergens:

  • Check the pollen levels nearby using online tools like pollen.com

  • When pollen levels are high, keep children indoors and close windows

  • Optimize allergy medications in anticipation of more intense pollen seasons

  • Change clothes and take off shoes upon entry into the house

  • Shower and shampoo at night before bed

Get Involved!

Plant trees and other vegetation in your neighborhood. Trees provide shade to help cool neighborhoods on hot days and can help improve air quality, especially in urban areas, and can improve mental health.  Check with the American Academy of Allergy, Asthma and Immunology’s guide to plant selection to learn which plants are safer for people with allergies.  Click below for more action items!
