This allergy season could be worse than those of past years in
the U.S., heavy snow and rain in many places, followed by a
sudden shift to warm weather, have led to a profusion of tree
pollen and mold. A new study in the Proceedings of the National
Academy of Sciences shows a link between warming temperatures
and a longer ragweed pollen season. According to researchers led
by Lewis Ziska of the U.S. Department of Agriculture, the
ragweed season is now 27 days longer in the northernmost areas
of North America, largely because winter starts later and ends
earlier, extending the time for pollen-bearing plants to thrive.
It's not the first piece of research to make the claim that
global warming will worsen allergies, but it's the most detailed
and it's peer-reviewed. In general, allergy seasons have been
getting longer and more challenging, although pollen counts and
allergy attacks vary widely from region to region. Dr. Mercola's
