New Science: Increasing Climate Change Will Trigger More Intense Allergies



Researchers have announced that they expect pollen allergies will likely intensify with increasing climate change. Additionally, scientists said as pollen counts continue to climb in North America, allergy sufferers will see longer and more intense bouts of sneezing, itching and runny noses.

The finding was presented at the meeting for the American College of Allergy, Asthma and Immunology by Rutgers University Dr. Leonard Bielory. He said that ragweed pollen production is dramatically increasing and it may double by 2040.

"Climate changes will increase pollen production considerably in the near future in different parts of the country,” said Bielory, according to ScienceBlog. “Economic growth, global environment sustainability, temperature and human-induced changes, such as increased levels of carbon dioxide, are all responsible for the influx that will continue to be seen.”

Researchers at Rutgers found that pollen counts, which averaged 8,455 in 2000, will likely reach 18,285 or higher by 2040.

Scientific American said that not only will pollen production increase because of warmer temperatures, but pollen seasons will also start earlier and end later.

Researchers made similar conclusions in an earlier study by the U.S. Department of Agriculture that said frosts were beginning later and finishing earlier than ever, causing an expansion in ragweed.
