Nitrous Oxide: Most important Ozone Depletion Emission

Nitrous oxide is a powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning.
Drawing Down N2O to Protect Climate and the Ozone Layer, a new report by the UN Environment Programme (UNEP), warns that nitrous oxide is now the most important ozone-depleting emission and the third most potent greenhouse gas released into the atmosphere.
"Although not as prevalent in the atmosphere as CO2 in terms of mass, N2O - commonly known to many as 'laughing gas' - is far from a laughing matter in respect to climate and ozone damage as it has a disproportionate impact on global warming because of its radiative properties and long lifetime in the atmosphere, which is 120 years on average. Action on these emissions offer yet another opportunity to keep the world under a 2 degree C temperature rise,"
Desert lands, especially the zones where cultivation practices like irrigation and usage of organic fertilizers produces N2O and has tendencies of contributing to regional and local green house effects.

Warmer sea surface temperatures could intensify tropical storm wind speeds, potentially delivering more damage if they make landfall. Based on sophisticated computer modeling, scientists expect a 2-11 percent increase in average maximum wind speed, with more occurrences of the most intense storms. Warmer seas also mean more precipitation. Rainfall rates during these storms are projected to increase by about 20 percent and, as Hurricane Harvey showed in 2017, this can sometimes be the more destructive impact. These stronger storms can increase damage to human structures when they make landfall. They can also harm marine ecosystems like coral reefs and kelp forests. And an increase in storm frequency means less time for these sensitive habitats to recover. The only way to reduce ocean temperatures is to dramatically reign in our emission of greenhouse gases. https://www.nationalgeographic.com/environment/oceans/critical-issues-sea-temperature-rise/ https://www.c2es.org/cont...

Scientific evidence for warming of the climate system is unequivocal.

The current warming trend is of particular significance because most of it is extremely likely (greater than 95 percent probability) to be the result of human activity since the mid-20th century and proceeding at a rate that is unprecedented over decades to millennia. Earth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. This body of data, collected over many years, reveals the signals of a changing climate. The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century. Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. There is no question that increased levels of greenhouse gases must cause the Earth to warm in response. Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show t...
