And no of course not. Gases don't ionise as readily in the atmosphere as they do in water. Or in another sense C02 in water doesn't matter (so much) while C02 in the atmosphere does. If there are any Chemists (not the drugs variety) that want to chip in, then I would be very happy to concede my knowledge is limited. Is that you Xfool?
I do keep chipping in, yet I keep getting the same snide responses from Xfool, who is obviously not a Chemist.
https://www.climate.gov/news-features/u ... on-dioxide tells me that in 2019 the level of CO2 in the atmosphere was 409.8ppm. You can compare this with saturated air at 20°C, which contains water vapour at 23,000ppm (SWVP=17.5mmHg or 2.30%). Obviously water vapour is not always saturated, and is at a much lower partial pressure higher in the atmosphere, but its main effect is, as we know, in the Troposphere, and it often occurs as clouds formed of either water droplets or ice crystals. Clouds have a much greater effect that water vapour itself, which is why it is cooler on a cloudy day.
Increased temperature reduces the solubility of CO2 in water and increases humidity, so the question arises, does increased CO2 lead to increased temperature or vice versa? The obsession with CO2 is irrational.
Well thanks for chipping in TJK. Yes water vapour is the number one green-house gas but that's partly because it's so prevalent. I think CO2 is a more powerful green-house gas in the sense that 1ppm of CO2 has more of a greenhouse effect than 1ppm of water. The table in https://en.wikipedia.org/wiki/Greenhouse_gas shows greenhouse effect contributions of various gases.
Yet more generally I agree the water cycle has a more powerful effect. Most climate scientists seem to think that clouds are a net warming contributor, a finding I am very suspicious of. Where clouds block sunlight they have a cooling effect yet they insulate at night more?. In the tropics storms have a huge cooling effect, In the open ocean (not the Australian Coral sea) Sea Surface Temperatures seem to be limited to approximately 32 degrees centigrade. If it goes higher a storm develops which cools the air and sea surface.
It seems as if the water cycle is capable of negative feedback to increased CO2 emissions and heat.
