You're right!
It's that old "send me money and I'll make your life better" scheme!
Almost as if it were some grand plan, this water vapor, when solar influx is at its most intense, is wafted aloft to form highly reflective cloud tops, which put a quick cap on further warming. Quite ingenious! I'll bet Al Gore wishes he had invented that!
The Global Warming alarmists and Gaia worshippers, intent on promoting this scam before the truth can catch up with it, want to have laws passed, and United Nations Committees instituted. After which it will be too late to dislodge them.
The real inconvenient truth is that the Earth warms and cools based mainly on its orbital eccentricity, axial tilt, and the precession, or wobble of Earth's rotation which follows a twenty-three thousand year cycle, one of the Milankovitch Cycles, and the shortest one.
The preliminary evidence available from our short study of climatic variation is that Carbon Dioxide variability has almost nothing to with global temperatures. If anything at all has been changing, it is the amount of sunlight coming to us, and to Mars as well.
One further point that I like to make is that global warming is actually a good thing, promoting the growth of food in longer growing seasons, and an extension of the latitudes suitable for crops to be grown.
I would be even more in favor of it if it didn't take thousands of years to melt all that pesky ice left over from the last ice age. We've been warming for eighteen thousand years, and there's still a lot of ice to deal with!
