Atmospheric conditions affect the release of anemophilous pollen. Zhang et al. use a pollen emission model together with future climate data to simulate changes in pollen emission. The study shows that climate change driven pollen increase and seasonal changes may increase seasonal allergies

These simulations indicate that increasing pollen and longer seasons will increase the likelihood of seasonal allergies.
