Est-ce que ce que tu me dis est que la vapeur d'eau est la principale responsable du réchauffement climatique ?
Comme le dit Berslak c'est le plus gros gaz a effet de serre (a cause de son immense volume) c'est la raison que la Terre est tempéré, tu peux pratiquement le ressentir l'hiver la nuit nuageuse sont plus clémente que les ciels éclairci il me semble. Je ne sais pas si les changements en quantité de vapeur d'eau est la principale cause de l'augmentation de la température cependant, peut-être bien.
L'augmentation de la vapeur d'eau est un problème et un problème accélérant, plus la température augmente plus l'eau s'évapore, plus les glaciers fonde, plus l'air peut contenir plus d'eau avant de saturer et ainsi de suite.
https://phys.org/news/2008-11-vapor-major-player-climate.htmlWater vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change.

Specifically, the team found that if Earth warms 1.8 degrees Fahrenheit, the associated increase in water vapor will trap an extra 2 Watts of energy per square meter (about 11 square feet).
"That number may not sound like much, but add up all of that energy over the entire Earth surface and you find that water vapor is trapping a lot of energy," Dessler said. "We now think the water vapor feedback is extraordinarily strong, capable of doubling the warming due to carbon dioxide alone."
https://www.esrl.noaa.gov/gmd/ozwv/wvap/Most relevant to our study is water vapor’s effects on the Earth’s energy budget, influencing both the incoming solar radiation and outgoing heat (IR). Variations in the amounts of water vapor in the atmosphere are natural and normal, but changes in its vertical distribution, especially in the upper troposphere and lower stratosphere, may be indicative of changes in the Earth’s climate. For this reason there is great interest in long-term measurement records of water vapor vertical distributions in the UTLS as they may reveal changes in atmospheric dynamics resulting from climate change.
