• Climate change and increased carbon emissions are causing allergy seasons to start earlier, last longer, and produce more pollen.
• Pollen concentrations have increased significantly over the last three decades, impacting a substantial portion of the population.
• Experts recommend a combination of avoidance strategies, over-the-counter medications, and consulting with allergists for effective allergy management.

Allergy seasons are intensifying, impacting millions of individuals in the United States and the UK. Multiple sources attribute this trend to climate change, which leads to longer growing seasons for plants, increased pollen production, and wider dispersal of allergens. The longer seasons and higher pollen concentrations are causing more severe symptoms and affecting a larger portion of the population. Experts recommend a multifaceted approach to managing allergies, including preventive measures, over-the-counter treatments, and professional medical advice.

• What: Allergy seasons are starting earlier, lasting longer, and producing more pollen due to climate change and increased carbon emissions.
• Who: Individuals with seasonal allergies, allergists, researchers, and organizations like the Allergy and Asthma Foundation of America, USA National Phenology Network, UK Health Security Agency (UKHSA), and Mayo Clinic.
• When: Allergy season typically begins in spring (around March) and ends in fall (as late as November), but research suggests it is expanding. Spring sees tree pollen, summer brings grass pollen, and fall is dominated by weed pollens.
• Where: The trend is observed across North America and the UK. Specific locations mentioned include the Northeast region of the US and the UK.

The lengthening and intensification of allergy seasons pose a significant public health concern. The consensus across multiple sources is that climate change is a primary driver, leading to increased pollen production and longer growing seasons. This, coupled with higher carbon emissions, exacerbates the problem. Effective management requires a combination of individual actions, such as monitoring pollen counts and using air filters, and broader efforts to address climate change. Consulting with allergists is crucial for personalized treatment plans and long-term solutions.

Research has definitely shown that the seasons are indeed expanding. We're seeing longer pollinating seasons. We're seeing higher levels of pollen.

Allergies are essentially your immune system overreacting to things that you're exposed to in your environment.

Allergy season is getting longer -- in fact it is an average of 13 days longer compared with 20 years ago.

You don't have to suffer. Allergists have the expertise and tools to get you feeling better quickly.

The intensifying trend of worsening allergy seasons is driven by climate change and elevated carbon dioxide levels, resulting in longer and more severe pollen seasons. These environmental shifts not only extend the duration of pollen exposure but also increase pollen production and allergen potency, exacerbating allergic rhinitis and asthma symptoms. Management strategies should include personalized treatment plans from allergists, preventative measures, and addressing underlying environmental factors. Furthermore, actions to reduce personal carbon emissions, planting appropriate trees, and supporting policies to reduce air pollution can also help to mitigate the impact on public health.
