• Pollen allergies affect over 30% of the global population, making them a significant public health and economic issue as people feel ill and miss work.
• Our research shows that, as greenhouse gases warm the planet, their effects are driving longer and more intense pollen seasons.
• To help allergy sufferers manage their symptoms in our changing climate, we’re building better pollen forecasts for the future.

Why pollen is increasing

• Pollen – the dustlike grains produced by grasses and plants – contains the male genetic material for a plant’s reproduction.
• Rising global temperatures will boost plant growth in many areas, and that, in turn, will affect pollen production.
• Carbon dioxide fuels photosynthesis, leading to increased growth and the potential for more pollen production.

Pollen changes will vary by region

• We looked at 15 different pollen types, rather than treating all pollen the same as many past studies have.
• Our study found that the amount of pollen increase in a specific region depends on the types of vegetation.
• The Pacific Northwest is likely to see peak pollen season a month earlier because of the early pollen season of alder.
• A study in 2021 found that the overall pollen season was already about 20 days longer in North America than it was in 1990 and pollen concentrations were up about 21%.

Silver lining: We can improve pollen forecasting

• Most pollen forecasts right now provide a very broad estimate of where and when pollen counts will be high.
• Part of the problem is that there aren’t many observing stations for pollen counts.
• It’s a very labor-intensive process to measure different types of pollen.
• Our model, if integrated into a forecasting framework, could provide more targeted pollen forecasts across the country.
• We also know how temperature influences when pollen comes out – what scientists call the phenology of the pollen.
