A study of long-term pollen data from 60 North American stations from 1990 to 2018 finds that pollen seasons have lengthened by 20 days and pollen concentrations have increased by 21% over that time-period, and that anthropogenic climate change is likely the dominant driver of pollen season lengthening and a significant driver of pollen concentration increase.
