The more people get pollen allergy due to rising global temperatures and carbon dioxide concentrations in US August 03 2022, 16 Comments
There are three main types of pollen allergy: tree pollen allergy, grass pollen allergy, and weed pollen allergy. Tree pollen is the first pollen to appear each year in the United States. It is responsible for most spring pollen allergy symptoms. It also often overlaps with grass pollen in the spring and summer.
Across the country, pollen season is starting earlier and intensifying because of rising global temperatures and carbon dioxide concentrations. Previous research showed that pollen season lengthened by 20 days over the past three decades across North America, while pollen concentrations increased by 21 percent.
