Oct. 7 (UPI) — Around the world, nitrous oxide emissions are rising, imperiling the effort to meet the climate goals set by the Paris Agreement.
According to a new study, published Wednesday in the journal Nature, the growing use of nitrogen fertilizers by industrial agriculture has led to a dramatic increase in N2O emissions.
For the study, researchers analyzed major N2O sources and sinks all over the world. The effort was aided by scientists from 48 research institutions in 14 countries.
“This study presents the most comprehensive and detailed picture to date, of N2O emissions and their impact on climate,” lead study author Parvadha Suntharalingam, climate scientist at the University of East Anglia in Britain, said in a news release.
The data showed modern atmospheric nitrous oxide levels are 20 percent higher than preindustrial levels, increasing to 331 parts per billion in 2018 from 270 parts per billion in 1750.
