And your point? That thousands of the most intelligent scientists on earth are all retarded and gullible and that there is actually no issue with our environment and we should all read Piezoe's 5 line rebuttal to get schooled on HIS "facts"? Are some environmentalist diehards overstating facts? They certainly are. But climate change deniers are the much more ignorant breed for sure.
In the interest of bringing the level of the above post up to nearly that of chit chat, it's necessary to point out that CO2 is not 2%; its 50 times less than that, at 0.04%, according to recent measurements. It varies widely from one place to another near the Earth's surface. The 0.04% figure is thus a mean value, or should be, unless one of the climate alarmists, like that screwball Hansen, cheated by reporting only the figure measured next to an active volcano . Also it won't hurt to mention that CO2 is not "25 meters thick," as though it was the icing on a giant, round birthday cake; rather it is distributed in roughly the same mean percentage (better expressed as 405 ppm) throughout the atmosphere. The gases in the atmosphere comprise a gas solution, i.e., they remain mixed, in the same proportions despite their differences in molecular weight, due to thermal, or kT, energy. The relative proportions of atmospheric gases are the same more or less throughout the atmosphere. Is the atmosphere only "5000 meters thick"? If you say so, however there is still "atmosphere" well above 16,250 feet.
