Experts say limiting the release of nitrous oxide is crucial for keeping warming below the critical 1.5°C threshold of the Paris Agreement.

Analysts say the country will burn a lot more natural gas in the coming years to meet soaring electricity demand, potentially locking in decades of heat-trapping emissions.

Cornell researchers have discovered a way for ammonia oxidizing archaea (AOA), one of the most abundant types of microorganisms on Earth, to produce nitrous oxide, a potent and long-lasting greenhouse gas.

Joe Murphy and Joe Robertson's play Kyoto – first seen at the RSC in Stratford – is set at the UN Climate Change Conference in 1997, when countries around the world agreed the first international treaty on curbing greenhouse gas emissions.
