Scientists link allergy spike to climate change

If you're feeling as if allergy season is year round, you're not alone.

Scientists say the rise in temperatures associated with climate change might have an unexpected consequence: more allergies among more people.

Italian researchers say higher temperatures are lengthening the pollen season for some plants and trees, increasing the pollen load they produce. That's causing a rise in the number of people who are developing allergies to certain pollens. They add the increase in global radiation determines an advance of pollen season and an increased period of exposure to the pollens.

Their findings were presented to the annual meeting of the American Academy of Allergy, Asthma and Immunology.
