Climate Change and Allergy

Climate change, hurricanes, extreme temperature variations seem to be the new norm. The effect of the weather on plant life leads to more allergy symptoms because greenhouse gases increase temperature and rainfall and the higher carbon dioxide promotes photosynthesis.

What does this means for the allergic patient? If you’re allergic to:
Trees–warmer winters could mean earlier flowering, delayed or even decreased flowering.
Ragweed–pollen season is already getting longer because ragweed distribution is increasing northward
Fungi–Alternaria, a major cause of asthma in the fall depends on plants for its own survival. If plants life is altered by global warming, this fungus will thrive. Furthermore, thunderstorms may lead to sudden surges in the levels of this fungus.
