ROANOKE, Va. – Though our current cold snap provides temporary relief from the sneezing, coughing and itching that comes with allergy season, the growing season as a whole is growing.
This is due, in part, to the warming trend on a local, statewide and national level. In Roanoke City alone, three of the top five warmest years have come within the last decade.
“On any average year, it’s a couple weeks longer than it was about 50 years ago.”
What that means is that pollen can show up earlier and last longer into the year. For those with more severe allergies, “This can trigger asthma attacks and can lead to more hospitalizations.”
Sublette tells us that’s already been seen in larger urban centers in the Northeast. The main driver to a warming planet is the increased emission in carbon dioxide. A 2014 study in Massachusetts shows that with more carbon dioxide comes an increase in pollen.
