In Guadalajara, 125 miles east and 5,200 feet up from here, the morning temperatures are always lower than here on the shore of the Pacific. That's because the atmosphere is thinner at 5,200 feet. Hence there is less water vapor in the atmosphere, and more of the earth's infrared radiation escapes at night.
On the Sahara Desert, when the sun goes down, the temperature drops to below freezing in an hour – because without atmospheric water vapor, the earth's infrared radiation beams straight out into space.
So since it is water vapor that keeps the surface of the earth warm at night, it's obvious that the evaporation of human sweat is causing the planet to get warmer!
Yeah, I know. That's stupid. But it's one level of common sense above the stupidity of saying that human generated carbon dioxide is heating up the planet, because water vapor actually does have the concentration to cause such an effect.
Oh, but there's one thing I forgot to mention. The daytime temperatures are higher in Guadalajara than in Puerto Vallarta – and they are way higher on the Sahara desert. That's because the atmospheric water vapor in Puerto Vallarta absorbs some of the sun's infrared radiation and re-radiates it back into space, thus keeping the daytime temperatures far lower than they would be without that infrared shield of water vapor.
So even if carbon dioxide did exist in our atmosphere at a significant concentration, it would only keep the earth warmer at night and cooler during the day, just as water vapor does. And incidentally, if carbon dioxide currently existed at a concentration capable of having any effect at all on our temperature, daytime temperatures in the Sahara Desert would be dropping and nighttime temperatures would be rising.
They are not.
The truth is that, at a pitiful concentration of 0.04 %, carbon dioxide doesn't have the chance of an ice cube in a hot toddy of swamping the effect of the 2 % water vapor in our atmosphere. And if it did, it would only assist water vapor in its amelioration of the violent temperature swings caused by the difference in solar radiation between noonday and midnight.
Furthermore, carbon dioxide is a vital component in the ecology of the planet. Humans, along with all the other animals on earth, are green plant parasites, and the green plants need carbon dioxide to manufacture carbohydrates, the only food animals are capable of metabolizing.
And the more carbon dioxide available, the more prolific the vegetation. And the more lush the vegetation, the more carbon dioxide is converted to carbohydrates. So even if we could reduce atmospheric carbon dioxide, it would be a dumb thing to do.
But the raw truth is we are simply incapable of significantly reducing atmospheric carbon dioxide. 97 % of all carbon dioxide that enters the atmosphere comes from natural sources – from rotting vegetation to fish flatulence. If the entire human race were to disappear from the planet tomorrow, the reduction in carbon dioxide would be only 3 %!
And for this Obama wants to spike our utility rates and impoverish millions of Kentucky, West Virginia, and Pennsylvania coal miners.
Talk about stupidity!
