In this undated photo provided by Atlanta Allergy & Asthma, Dr. Stanley Fineman looks through a microscope at Atlanta Allergy & Asthma Center in Atlanta to examine the pollen.
Just look at cherry blossoms opening several days earlier in Japan and Washington, D.C., he said.
The South and southern Midwest are getting pollen season about 1.3 days earlier each year, while it’s coming about 1.1 days earlier in the West, he said.
The northern Midwest is getting allergy season about 0.65 days earlier per year, and it’s coming 0.33 days earlier a year in the Southeast.
But since the 2000s, about 65% of earlier pollen seasons can be blamed on warming, he said.
