According to a concerning new study.
continues. Changes in temperatures and rain patterns will increase the daily maximum amounts of pollen emissions by about 35% to 40% and annual pollen emissions by about 16% to 40% by the end of the century, according to the paper. Factoring in future carbon dioxide emissions makes the picture look much bleaker, increasing pollen production up to a staggering 200% throughout the U.S.
The researchers made their predictions by using data modeling to simulate how climate change will affect the production of 15 different kinds of pollen in various regions of the U.S. They looked into how climate change is predicted to affect the local weather patterns , as well as the growth cycles and pollen seasons of the local plant life.
Generally speaking, the northern part of the country is expected to see the biggest shifts in pollen season, in accordance with bigger temperature increases. And the precise effects will not be uniform throughout the U.S. Modeling indicates that in the Northeast, for instance, rising temperatures and carbon dioxide emissions mean that tree species that have traditionally produced pollen on a more staggered timeline will increasingly see their pollen seasons overlap with one another .
