Water vapor absorbs way more wavelengths of the spectrum than CO2 which limits the affect of the trace gas. CO2 is NOT a driver of climate!
It is true that water vapor is a powerful greenhouse gas. It is also true that CO2 is the driver of our climate....It not only increases temperature, but that increased warming allows the atmosphere to retain more water vapor...A well known feed back cycle.
From the page I linked to...You should try reading it...
People sometimes ask me why carbon dioxide is important for climate, given that water vapor absorbs more infrared radiation and the two gases absorb at several of the same wavelengths.
The reason is that Earth's upper atmosphere controls the radiation that escapes to space. The upper atmosphere is much less dense and contains much less water vapor than near the ground, which means that adding more carbon dioxide significantly influences how much infrared radiation escapes to space.

CO2 doesn't drive climate? Take a trip to Venus (96% CO2) and report back with what you find out.
Water vapor is a greenhouse gas but it cannot warm the planet because if water vapor increases, precipitation increases, causing a reduction in water vapor pressure. Water vapor therefore is self-correcting and cannot by itself start a feedback loop. CO2 cannot precipitate (well, it can, but it never gets cold enough here for that to happen) so once it is injected into the air most of it stays there forever. As CO2 rises and temperatures rise, then the water vapor pressure rises, so the air can hold more water, causing increased high precipitation events, as we have already seen. Warming also increases evaporation so droughts will increase, as we have already seen.
Normal people don't fear a vital gas CO2 as a pollutant, especially @ 0.04%!
The percentage is meaningless. Go breath cyanide gas at 0.00025%. You will be dead within a minute.
But of course no one ever said CO2 at .04% is directly harmful to a person. Anyone who doesn't understand that has no business commenting on a public forum regarding climate change.

Venus is closer to the Sun; revolves very slowly in retrograde, and all CO2 that was sequestered in its crust is now in its atmosphere. Apples to anvils in comparison to the Earth! CO2 is an indicator of climate here, not a driver.

This is true, and also consider that the levels of CO2 in the atmosphere have nearly doubled since the beginning of the industrial age. Water vapor is relatively constant. If water vapor levels increased that much you can be sure they would drive climate change as well.
An Antarctic base recorded a temperature of 64.9 degrees F. If confirmed, it's a record high.
The World Meteorological Organization says the Antarctic Peninsula, on the continent’s northwest tip near South America, is among the fastest warming regions on Earth. https://www.nbcnews.com/science/scie...m_npd_ms_tw_ma

By doing what? No doubt what drives most of the opposition against doing anything about global warming is because it would require raising taxes and more restrictive environmental regulations. So they quite passionately insist it's all based on pure falsehoods. The opposition would rather be short sighted by paying higher costs through higher insurance rates and other higher prices brought on by more intense storms.
But the study only covers historical temps in the USA. What about world wide?
