Climate change worsens allergy seasons

Climate change is directly contributing to longer and more severe pollen seasons across the Northern Hemisphere, exacerbating allergy symptoms for millions. Rising temperatures and increased carbon dioxide levels are causing trees to bloom earlier and produce more pollen, while also extending the growing season for weeds. This trend is leading to more intense allergy symptoms that are becoming harder to manage with traditional treatments. Additionally, climate change-related factors like heat waves, air pollution, and increased humidity are creating favorable conditions for mold growth, further complicating allergy management and increasing risks of respiratory issues.
