Nothing to sneeze at: Global warming triggers earlier pollen

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. When Fineman started 40 years ago as an allergist in Atlanta, he told patients they should start taking their medications and prepare for the onslaught of pollen season around St. Patrick’s Day. Now he tells them to start around St. Valentine’s Day.
