Within the upcoming century, people can expect to see a spike in their exposure to grass pollen and allergens. Researchers from the University of Massachusetts Amherst estimated that exposure over the next 100 years can increase by up to 202 percent, which can lead to increases in carbon dioxide (CO2) and ozone (O3). These changes could have a huge impact on human health.

"This is the first evidence that pollen production is significantly stimulated by elevated carbon dioxide in a grass species and has worldwide implications due to the ubiquitous presence of grasses in all biomes and high prevalence of grass pollen allergy. These results are similar to our other stud...
