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 ;-)

There are actually several “greenhouse” gasses..../Yep, I've been pointing this out for years.

Thanks for the feed back.
