Climate change may be making your allergies much worse. According to researchers, increased temperatures have already led to noticeably longer pollen seasons, with oak, birch, and ragweed dispersing pollen more intensely and for longer stretches. New Jersey, for example, hit record high pollen counts just this February. Reports from the Asthma and Allergy Foundation of America estimate that some 60 million Americans already suffer from an allergy of some kind, costing $21 billion annually in medical expenses. That figure could rise exponentially with pollen counts expected to double by 2040.
