Global Warming is a Gas

Share

Years ago, I used to play a joke on friends of mine talking about how dihydrogen monoxide poisoning threatened all of our waterways, estuaries, and aquifers. It was in our cities, in our food, and now that I think about it, it's in the air all around us. Of course, my scientifically minded friends soon realized that dihydrogen monoxide, nefarious though it may sound, is actually water, and then the joke was on them for their concern.

The fact of the matter is that the joke is still on everyone who believes the global warming hype. Like it or not, water's primary responsibility in protecting and preserving life is as a buffer- whether it be temperature, pressure, pH, etc. The water cycle regulates temperature. When the temperature rises, evaporation occurs as water absorbs most of the heat (very few things can absorb as much energy in the form of heat as water) and hydrates the air, eventually leading to precipitation when the atmospheric concentration of water vapor exceeds the loading limit. As water falls from the sky, it cools the earth even further, setting us up for the cycle to repeat itself. In fact, this oscillatory cycle occurs every year in the form of the seasons.

No matter how much carbon dioxide may be in the atmosphere, there is always more water vapor as a total component. Where there is less water in the air per capita the climate borders on being arid; where it is high, we term that tropical. If you run a total dissolved CO2 measurement in those climates, you will see that it's statistically insignificant. Dihydrogen monoxide is the major greenhouse gas. It traps heat under clouds, blocks the sun, absorbs heat, and bears most of the burden of regulating temperature. As opposed to other chemical species, water's rate of transmission of energy from heat is slower, given the activation energies at the points of phase transition. Water, unlike CO2, occurs naturally on earth in every phase- solid, liquid and gas, and it can move between them in this world without help from man.

The world doesn't need our help either. If man really got in the way of upsetting the buffer, the earth would eliminate us as a constraint.
