A new study coming out of Atlanta finds that your allergies might get a whole lot worse in a warming climate.

According to the Atlanta Journal-Constitution:

“By the end of this century, the city’s pollen season could start as many as 20 days earlier and last 20 days longer, according to the researchers behind a new study published Tuesday in the journal Nature Communications. The study also found that overall pollen production may climb by as much as 28% around Atlanta and 35% across Georgia by the last two decades of the 21st century.”
