NEW YORK, May 28 (UPI) -- U.S. health researchers say projected global warming will result in more children with respiratory ills.
In one scenario, researchers Mount Sinai School of Medicine in New York City project respiratory hospitalizations for children under age 2 will rise between 4 percent and 7 percent by 2020 because of increased air pollution.
The researchers used two scenarios that differed by the amount of projected ozone precursor emissions -- chemicals that are converted to ozone by light and heat. In both scenarios, ozone levels rise by 2020. The study estimates are likely to be conservative, the researchers say, because population was held constant, a single dose response function was used for the entire area and most counties were not weighted by race and ethnicity.
"These significant changes in children's hospitalizations from respiratory illnesses would be a direct result of projected climate-change effects on ground-level ozone concentrations," lead study author Dr. Perry Elizabeth Sheffield says in a statement.
The findings were presented at the Pediatric Academic Societies Annual Meeting in Baltimore.
