So it’s not CO2, it’s H2O?

From what I've read CO2 isn't even a green house gas. If it goes up it lags behind temp increases. Increased water vapor on the other hand has a vastly greater effect on temp increases and can be considered a green house gas. If I'm off on this I stand to be corrected.
Suffice it to say that when the earth decides to "do something" ain't nothun we can do about it.

CO2 is plant food so it is a greenhouse gas. Greenhouse growers actually BUY the stuff and run it in their greenhouses.

Yep, I've been pointing this out for years.

There are actually several “greenhouse” gasses. such as water VAPOR (not clouds) CO2, methane for example. Water VAPOR is BY FAR the largest contributor to a warm atmosphere.

CO2 is only about 0.04% of the atmosphere. Water vapor varies, but can be approximated at 4% of the atmosphere. So it’s TWO ORDERS OF MAGNITUDE more prevalent that C02 *and* it’s a more powerful greenhouse gas.

Water vapor, by the way, is a natural combustion byproduct of hydrogen. So ... anything that burns hydrogen is FAR from green by definition ;-)

I am wondering if the 10% excess moisture above us is one reason we are having so many major flood/rain events this past year?
