Extended Allergy Seasons Linked to Climate Change
Research indicates that allergy seasons are becoming longer, resulting in increased exposure for those who suffer from allergies. A significant factor contributing to this trend is the rise in atmospheric carbon dioxide, which promotes greater pollen production from plants. Studies show that from 1990 to 2018, the pollen season in North America has lengthened by over 20 days, largely due to higher temperatures and overlapping pollen emissions from different plants. This relationship between climate change and seasonal allergies highlights how environmental changes are affecting public health.
