Humans may be fueling global warming by breathing: new study
Humans may be fueling global warming by breathing, a new study suggests.
“Exhaled human breath can contain small, elevated concentrations of methane (CH4) and nitrous oxide (N2O), both of which contribute to global warming,” according to research released last week in the UK journal PLOS.
The methane and nitrous oxide exhaled by humans make up about 0.1 of the UK’s greenhouse gas emissions, the writeup said.
The gases are in addition to the carbon dioxide that humans exhale.
The study, led by Dr. Nicholas Cowan from the UK Center for Ecology and Hydrology, involved 104 adult volunteers and found that nitrous oxide was breathed out by every one of them, while 31 percent exhaled methane.
Those who did not exhale methane in their breath still probably released the gas “ion flatus,” the study said, referring to burping and flatulence.
