Summary
[edit]DescriptionN2O Protoxyde d'azote Nitrous Oxide évolution sur 260 ans selon AEE de 1750 à 2020.png |
Français : Evolution de la teneur en N20 (protoxyde d'azote) dans l'atmosphère sur 260 ans (rappel : le N20 est un gaz à effet de serre, et il détruit la couche d'ozone), d'après les données chiffrées retenues par 'Agence européenne de l'environnement :Unité : ppmv (parties par milliard en volume)
voir aussi sur Commons, une comparaison avec 3 autres gaz à effet de serre, montrant notamment une croissance aussi régulière que celle du CO2. English: Evolution over time (260 years) of the contents of the Earth's atmosphere of N2O, a greenhouse gase ; Nitrous oxide occurs in small amounts in the atmosphere, but recently has been found to be a major scavenger of stratospheric ozone, with an impact comparable to that of CFCs. It is estimated that 30% of the N2O in the atmosphere is the result of human activity, chiefly agriculture. English name of the unit PPB = parts per billons (PPB) |
