Allergy Season Lengthens

Poster, source material and preliminary concepts shown above.



  • Climate change contributes to the amount of airborne pollen
  • Plants produce more pollen due to higher carbon levels in the atmosphere
  • A recent study revealed ragweed pollen season has increased by as much as 10-22 days for areas in and around Minnesota
  • Growing evidence shows that pollen is becoming more allergenic & the associated health burden, especially on individuals with preexisting respiratory problems, may be substantial
