Nitrous Greenhouse Threat
A new study finds that emissions of the ozone-eating greenhouse gas nitrous oxide have increased more than expected.
Researchers from the Norwegian Institute for Air Research and other institutions found that the increased use of fertilizers containing nitrogen has been the main driver in the increase.
“We see that the N2O emissions have increased considerably during the past two decades, but especially from 2009 onwards,” said author Rona Thompson.
While fertilizer use has made it possible to grow a lot more food, the researchers say it resulted in destruction of stratospheric ozone and further climate change.
Current Fossil Fuel Plans Will Shatter Paris Climate Limits
The world’s top fossil fuel-producing nations are on track to extract enough oil, gas and coal to send global temperatures soaring past the goals of the Paris climate agreement, according to a United Nations report published Wednesday.
If countries follow through on their current plans, they will produce about 50 percent more fossil fuels by 2030 than would be compatible with the international goal of keeping global warming under 2 degrees Celsius, the report said.
They would blow past the more ambitious target of keeping warming under 1.5°C, the report found, with countries poised to produce twice as much oil, gas and coal by 2030 than would be allowable to meet that goal.
