"I do but the only one that matters is water vapor which is ignored by all the 'Models.'" By the Light of the Silvery Moon Arrhenius, S. (April 1896). On the influence of carbonic acid in the air upon the temperature of the ground. The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science Series 5, 41 (251). 39 pages. In Arrhenius’ 1896 paper we witness the birth of modern climate science. Working with incomplete theoretical basis and a few beams of moonlight, Arrhenius calculated the warming that would result from doubling the CO2 concentration of the atmosphere, a quantity that modern climate scientists call the climate sensitivity. Granted he may have gotten lucky to get what is essentially the right answer, but more importantly his approach was well guided, and brilliantly creative. Along the way, Arrhenius described the water vapor feedback, which about doubles the impact of changing CO2 , and the ice albedo feedback, which is largely responsible for the intensified warming in high latitudes. Although Arrhenius is best known for the Arrhenius equation, which describes the effect of temperature on the rates of chemical reactions, his 1896 paper contribution stands squarely at the foundation of Earth science. untitled (uchicago.edu) -- Steamy Relationships: How Atmospheric Water Vapor Amplifies Earth's Greenhouse Effect – Climate Change: Vital Signs of the Planet (nasa.gov) Some people mistakenly believe water vapor is the main driver of Earth’s current warming. But increased water vapor doesn’t cause global warming. Instead, it’s a consequence of it. Increased water vapor in the atmosphere amplifies the warming caused by other greenhouse gases. It works like this: As greenhouse gases like carbon dioxide and methane increase, Earth’s temperature rises in response. This increases evaporation from both water and land areas. Because warmer air holds more moisture, its concentration of water vapor increases. Specifically, this happens because water vapor does not condense and precipitate out of the atmosphere as easily at higher temperatures. The water vapor then absorbs heat radiated from Earth and prevents it from escaping out to space. This further warms the atmosphere, resulting in even more water vapor in the atmosphere. This is what scientists call a "positive feedback loop." Scientists estimate this effect more than doubles the warming that would happen due to increasing carbon dioxide alone.
