Allergies are so bad this year mainly due to climate change, which is causing warmer temperatures and milder winters. These changes lead to earlier, longer, and more intense pollen seasons because plants bloom earlier and release pollen for extended periods. Increased carbon dioxide levels also stimulate plants like ragweed to grow faster and produce more pollen. Additionally, urban heat islands and unpredictable weather patterns contribute to higher pollen counts and more allergen exposure. Pollution and mold growth from changing weather further worsen allergy symptoms. Overall, these environmental shifts mean many people experience stronger and longer-lasting allergy symptoms this year compared to previous years.
Key Factors Making Allergies Worse This Year:
- Climate change extends growing seasons and disrupts natural plant cycles, causing earlier and prolonged pollen release.
- Higher carbon dioxide levels promote allergenic plant growth and increase pollen production.
- Milder winters and warmer springs trigger longer allergy seasons.
- Unpredictable weather patterns like sudden rain and wind spread pollen and mold spores.
- Urban environments amplify pollen concentration due to the urban heat island effect and pollution.
- Increased presence of mold spores triggered by warmer and wetter conditions worsens respiratory symptoms.
These combined factors explain why many people are suffering from more severe, longer-lasting allergies during the 2025 allergy season.
