Al Gore takes the high road during interview

He's too kind to them. At least those others were driven by actual belief, these fearmongers are driven by corporate brainwashing.

I know math is probably way over your head but here's a link anyway.

I'm gonna post the text too.

Crunching the Numbers

There's no Mechanism for Carbon Dioxide Causing Global Warming

Links to references are found on "Global Warming Main Page".

Carbon dioxide cannot trap significant energy near the surface of the earth.

claimed heat due to atmosphere --- 33°C

95-99% due to various things --- 31.4°C

1-5% due to infrared radiation from earth's surface --- 1.65°C

8% of infrared bandwidth available to CO2 --- 0.13°C

3% of CO2 produced by humans --- 0.0039°C

5% of absorption "unsaturated" for global warming --- 0.0002°C

claimed global warming --- 0.6°C


Atmospheric Heat

Scientists have been saying, with no disagreement, that the atmosphere is responsible for heating the globe by 33°C. Propagandists (promoters of supposed consensus view that humans are the cause of global warming) try to create the impression for the public that all 33 degrees is caused by "greenhouse gasses". It's not true.

Infrared radiation is 1-5% of heat leaving the earth's surface

The atmosphere acquires heat in a variety of ways, and very little through radiation. Here's how it works:

The atmosphere is transparent to most of the sun's radiation. This means that much of the radiant energy from the sun goes through the atmosphere without heating it, and then it is absorbed by the earth's surface, where it is converted into heat. There are various exceptions which are not relevant to global warming from carbon dioxide. For example, water in the air absorbs some of the solar energy, and ozone absorbs a little.

The important point is that radiation from the sun is too high of a frequency to be absorbed by carbon dioxide, which only absorbs infrared radiation. Something as hot as the sun cannot emit low frequency radiation.

Most of the heat leaves the earth's surface through conduction, convection and evaporation (about 95-99%), while very little leaves as infrared radiation (about 1-5%).

Nowdays there is a good indication that very little radiation is given of by the earth's surface or the atmosphere, and it is night vision equipment. At 80°F, or 27°C, (typical temperatures) there is very little radiation picked up by night vision equipment.

I therefore estimate that 95-99% of the heat on the earth's surface enters the atmosphere through conduction, convection or evaporation, while about 1-5% gets there by radiation emitted from the earth's surface.

This means, of the 33°C which the atmosphere is said to add to the globe's temperature, about 1.65°C is due to radiation which can be absorbed by the "greenhouse gasses".

Promoters of global warming hype try to balloon infrared radiation out of proportions, sometimes claiming that it may be as much or more than the sun's energy. That claim is incredibly absurd. Night vision equipment shows that matter at normal temperatures gives off very little infrared radiation.

The NASA web site says 41% of the energy which leaves the earth's surface is in the form of radiation, which is absurd. The IPCC probably uses the same number. The rationalizers pick numbers with no relationship to reality. If that number is used, the breakdown is this:

claimed heat due to atmosphere --- 33°C
59% due to various things --- 19.5°C
41% due to infrared radiation from earth's surface --- 13.5°C
8% of infrared bandwidth available to CO2 --- 01.1°C

This is the maximum heat carbon dioxide can add to the atmosphere— 1.1°C. It means if the CO2 could be doubled, it would only increase the atmospheric temperature by 1.1°C. Even if humans are responsible for 30% of it, which is absurd, the "anthropogenic global warming" would be 0.33°C, which is not what they are claiming.

Also, they claim 49% of the heat gets into the atmosphere directly from the sun's energy being absorbed by such things as water vapor and ozone, which is absurd; but if true, the 1.65°C would need to be reduced by another 51% to 0.84°C. In other words, they can't get numbers which add up even after ballooning them out of proportions. Computer models take care of the discrepancies.

Carbon Dioxide Absorbs only 8% of Radiation

When radiation is emitted from the earth's surface, it is picked up by gasses in the atmosphere. Carbon dioxide has three narrow bands of absorption, and water vapor has several bands.

Measurements show that 8% of the radiation will strike carbon dioxide due to its narrow absorption bands. The other 92% of the radiation goes around the CO2 bands and strikes the water vapor, methane or other substances in the air.

This means, of the 1.65°C that radiation heats the atmosphere, at most 0.13°C could be attributed to CO2.

Humans put 3% of the CO2 in the Air
External Reference

Humans are said to put 3% of the CO2 in the air, while the rest of the CO2 is due mostly to biological decay and respiration. The hypothetical problem is that humans might double their production of CO2. Doubling would mean adding 3% to whatever CO2 does. A 3% increase in what CO2 does would mean increasing the 0.13°C by another 0.0039°C. This is the maximum amount of heating of the atmosphere humans would do by doubling their production of CO2—0.0039°C—until taking into account the next factor.

(The claim that humans caused a 30% increase in CO2 over the past 150 years is phonier than a three dollar bill. The actual increase was due to warmer oceans releasing more; but it was less increase than claimed, because numbers for earlier times are based on ice core measurements, which are dubious and not comparable to present measurements in the air. Oceans regulate the amount of CO2 in the air. If not, nothing would control the amount of CO2 in the air, and there would be so much, life would be impossible. claiming that the 3% which humans add multiplies to 30%, while the 97% which nature adds does not multiply is unscientific.)

Saturation Pertains to about 5% of the Absorption Peaks

Supposedly, the all-important effect occurs high in the atmosphere where the absorption peaks are not saturated. In the thinner atmosphere, the shoulders on the peaks shrink and do not overlap with the peaks for water vapor. The shoulders on the absorption peaks are very small—at most 5% of the absorption. This means the quantities above need to be multiplied by 5%. Then the effects of saturation result in, at most, 5% times 0.0039°C, which is 0.0002°C.

Apparently, not all climatologists are aware of this effect, where shoulder absorption is used to salvage the hype. If not, they are ignoring the fact that more CO2 only shortens the distance without adding more heat.

There is no Mechanism

These are hard numbers which can be estimated without much error. So propagandists need some way to explain how the heat is being produced. They claim the earth has already been heated 0.6°C by carbon dioxide, and 1-6°C more heating is expected in the future.

To salvage the global warming hype, "consensus" scientists pretend that there is an esoteric mechanism farther up in the atmosphere doing some vague thing to produce the heat. But they can't explain a mechanism. There's no such mechanism.

After the heat enters the atmosphere, the same dynamics of distribution exist: Convectional currents stir the air for about a month, while small amounts of radiation compete with convection for moving heat around. And then near the outer edges of the atmosphere, the energy escapes into space through radiation. Before it escapes, it doesn't matter whether the energy is in contact with CO2, water vapor or nitrogen.

These miniscule numbers show that there is no real mechanism for carbon dioxide creating global warming. There isn't something else that happens somewhere creating some other mechanism for CO2 causing global warming.

A Global warming raise of 1 C, which is a scientific fact, is pretty signifigant, and it's the only true variable out of all mentioned. And the only one that is growing.
