Is climate change causing allergy season?

Allergy seasons have been getting longer for the past few years. Many people wonder if allergy season would now be a year-round season? Experts and allergists believe it is a possibility and the year-long allergy season could be caused by climate change. “Due to climate change we’re seeing warmer temperatures everywhere and, as a result of that, pollen season is starting two, three, four weeks earlier in the spring because of the early thaw,” said Dr. Cliff Bassett, a fellow for the Asthma and Allergy Foundation of America. “In the fall, ragweed season is three to four weeks longer.”
