Have you noticed that when you go outdoors at night, if there are clouds, it is warmer than when the sky is clear? Clouds and rain are part of heat and air circulation at the Earth’s surface, like a saucepan heated from below, with water evaporating and condensing on the lid, by losing heat into space. The water cycle keeps Earth warm.

Global warming could be caused by moisture and clouds in the atmosphere increasing with time.

The change in the Earth-Sun heat transfer balance has been attributed to the Earth trapping more incoming radiation during daytime. If this is so, would it not reradiate it at night time, as part of the equilibrium? In any case, heat absorbed at the surface is said to be transferred from 0.045% of carbon dioxide gas to warm up 99.96% of the atmosphere by a supposed heat transfer process. The supposed role of carbon dioxide puzzles me.

The anthropomorphic heat gain could plausibly be held back by the insulating effect of moisture and clouds above water storages, combustion exhausts, agricultural evaporation, irrigation and transpiration from crop plants. The numbers in the diagram relate water quantities. The increase could be a small change to Earth’s energy input and output, but enough to be a significant cause of global warming. Other warming could be by anthropomorphic heat pollution. Reducing human water usage, evaporation from dams and combustion of hydrogen-containing fuels could perhaps lower the small heat gain of climate change.
