Climate Change Is Boosting Plant Pollens and Human Seasonal Allergies
Springâs arrival means seasonal allergies for nearly one-third of people in the United States. Climate change is exacerbating the issue, leading to longer and more intense pollen seasons, and a bad time for allergy sufferers. Trees are receiving mixed signals from the warming temperatures, resulting in an earlier onset of allergy seasons.
Pollen is responsible for triggering allergic reactions in individuals. When plants reproduce, pollen carries the male sex cells required for fertilization. Some plants rely on wind for pollination, producing lightweight pollen that can be easily dispersed in the air. When people with allergies inhale this pollen, their immune system reacts, causing symptoms such as sneezing, watery eyes, and itching.
Climate change, characterized by rising temperatures and increased carbon dioxide levels, contributes to higher pollen production. Plants use carbon dioxide for growth, and the abundance of this gas leads to increased pollen production. The combination of higher temperatures and carbon dioxide levels creates optimal conditions for plant growth and reproduction, resulting in more allergens for humans.
Contrary to popular belief, urban areas are not immune to the effects of pollen. In fact, trees planted in cities, including highly allergenic species like birch trees, exacerbate allergy symptoms. These trees produce abundant pollen, which can cling to clothes and surfaces, prolonging exposure even beyond the typical pollen season. Proper urban planning and landscaping, and planting less allergenic tree species, can help reduce the pollen problem in cities.
While the impact of climate change on pollen production is beyond individual control, there are steps individuals can take to minimize the effects of seasonal allergies. This includes getting an allergy test, consulting with a doctor for appropriate medication, monitoring pollen counts, practicing good hygiene to remove trapped pollen, selecting non-allergenic plants for gardens, and planting female trees and shrubs that do not produce pollen.
Climate change is leading to longer and more intense pollen seasons, increasing the misery of allergy sufferers. The rise in temperature and carbon dioxide levels directly impact pollen production, exacerbating allergic reactions. As climate change continues to affect our environment, the impact on public health, including a growth in the number of people with asthma, becomes a growing concern. Taking proactive steps to reduce exposure to pollen and seeking medical advice can help alleviate the symptoms associated with seasonal allergies.
