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.

Combustion, geothermal processes, hydro, solar and wind, all produce heat energy (or electricity), plus water vapour, plus carbon dioxide (some). All the heat energy, including that wasted, ends up eventually in the oceans, land, atmosphere or reradiated into space. Energy taken by hydro, solar and wind technologies and their waste, warm the Earth and are replaced from the Sun. Increase of heat energy, or entropy released, in all these processes, is sufficient to explain the reported global warming. 

Carbon dioxide is a mere 0.0042% of the atmospheric gases insulating the Earth from space. It does not act as a trace catalyst, like chlorofluorocarbon was explained to decompose ozone. Nor does it entrap infrared energy causing significant heating. To slow global warming, unnecessary energy consumption must be reduced. Part reduction replacing  carbon fuels with wind and solar would increase warming.
