New research has found that nitrous oxide from agriculture and other sources is accumulating in the atmosphere so quickly it puts Earth on track for a dangerous 3℃ warming this century.
greenhouse gas emissions
COVID-19 has affected global emissions in six economic sectors, with a significant decline in daily global emissions. Total daily emissions in early April were similar to those observed in 2006.
Nitrous oxide (N₂O) is the third-most-important greenhouse gas after carbon dioxide and methane. Human-driven N₂O emissions have been growing unabated for many decades, but we may have been seriously underestimating by just how much. In a paper published today in Nature Climate Change, we found global emissions are higher and growing faster than are being reported.
