Human exhalations are contributing to the ongoing increase in atmospheric carbon dioxide levels that are driving climate change, according to a new study released today from the University of Northwest Florida (UNWF).
The four-year-long study by atmospheric scientist Lawrence Meany concluded that human respiration and conversation could be responsible for up to 12 percent of the greenhouse gases entering the atmosphere every year. And, Meany discovered, that percentage appears to be growing.
“At current global population growth levels — about 77 million people per year — the contribution of human exhalations to carbon dioxide concentrations could reach 15 percent by 2025,” Meany said. “Such rising impacts from basic human physical activity suggest the IPCC (Intergovernmental Panel on Climate Change) might have vastly underestimated future projections of greenhouse gas levels.”
Ironically, Meany further noted, the IPCC’s continued efforts to negotiate a global successor to the Kyoto Protocol are actually themselve contributing to rising amounts of atmospheric carbon dioxide.
“It’s always been a cliche that politicians, and sometimes scientists too, are full of hot air,” Meany said. “Unfortunately, my findings indicate this is, in fact, literally true.”
Oh, and by the way … April Fool’s!
