00:00Allergy seasons are getting longer in many major U.S. cities due to climate change.
00:04A recent study by Climate Central found that the freeze-free period,
00:08which is the number of consecutive days with temperatures above freezing,
00:11has grown by an average of 20 days in nearly 90% of the 198 cities they analyzed since 1970.
00:19This means plants can grow longer and release more pollen,
00:23causing allergies to last longer and be more intense.
00:26Cities like Reno, Nevada, Myrtle Beach, South Carolina, and Toledo, Ohio,
00:30have seen some of the biggest increases in freeze-free days, reports Axios.
00:34With more CO2 in the air, pollen production could keep rising,
00:38making allergy seasons worse nationwide.
00:41So it looks like we might be reaching for that allergy spray a lot more in the future.
