Is Climate Change Really Man Made?

Carbon dioxide and the so-called 'greenhouse effect'

There exists in reality no such phenomenon as 'greenhouse effect' caused by carbon dioxide, methane or other so-called ‘greenhouse gases’.

- What are the arguments?

1. If such effect existed, say some scientists, it would violate the second law of thermodynamics. It says: ‘No process is possible whose sole result is the transfer of heat from a body of lower temperature to a body of higher temperature.”, which means, that such a body (in this case a warmer, lower part of the atmosphere) cannot warm itself, because it is surrounded by a cooler environment of upper part of the atmosphere and the outer space.
There are of course other scientists, who say the second law of thermodynamics has nothing to do with the greenhouse effect, because this law does not apply to individual photons, but to the net flow of energy in the entire system. So far so good, but even if the second law of thermodynamics could not be applied to the exchange of energy on a molecule level, there is another argument:

2. Molecules of CO2 can absorb heat radiation only in particular ranges, i.e. 2.7, 4.3 and 15 µm. These ranges constitute only 4% of the whole black body radiation emitted back into space. The absorption happens only when the radiation reaches a molecule of CO2. How much CO2 do we have in the atmosphere? About 0.385%!! In other words 99.615% of the heat radiation goes back into space. This means also that the increase of carbon dioxide in the Earth's atmosphere of 100% (doubling) would cause the rise of mean temperature on the Earth of at most 0.00154%, from say 15.0 Celsius  to 15.0002 degrees Celsius. Such change is barely measurable. Additionally, you would have to divide this value by 2, because ca. 50% of the Earth's surface at the same time is not receiving sun energy during the night, which lowers the black body radiation proportionally. And last of all, you would have to divide it by 2 again, because each molecule of CO2 would reemit the radiation in every direction, not only in the direction of the Eart's surface. Up to 50% would disappear in outer space.

3. Most of the rise in CO2 comes from natural sources. Man currently causes about 8 gigatons of carbon dioxide to be injected into atmosphere, which is about 4% of the natural anual flux. Burning fossil fuels is not increasing atmospheric CO2. It is temperature that drives CO2 release, not the other way round. Just as it always has been.
It is ten times as likely that atmospheric CO2 is coming from natural sources, namely the warming ocean surface, as it is likely that it is coming from anthropogenic sources. The changes in CO2 track ocean surface temperature, not global carbon emissions. Burning fossil fuels is not increasing atmospheric CO2. Recovery from the Little Ice Age, driven by the sun, is causing the oceans to release CO2. It is temperature driving CO2 release, not the other way around. Just as it has always been. - See more at:

4. Nobody and nothing can stop the cooling processes of the Earth. The cooling of the Earth's surface occurs not only through thermal radiation, but also through thermal conduction and, what is especially important for weather conditions, through thermal convection. Convection belongs to heat transfer through mass transfer and leads sometimes to very turbulent mixing of the atmosphere. Warm air moves up and, in compensation, cold air flows down.
The Earth constantly gives off heat into space through long wave electromagnetic thermal radiation, namely with light velocity. Therefore our planet is so much dependent on the compensive thermal radiation from the sun. A body can warm itself up only, when in a certain time interval, it is receiving more energy than it is giving off (positive balance). During a day this balance is mainly positive and the Earth's surface warms up. At night the balance is negative and the surface cools down.
According to the German meteorologist and physicist dr Wolfgang Thüne, the assumptions and calculation of the so-called 'natural greenhouse effect' , are completely wrong. The starting point for this theory is the solar constant of 1,368 W/sqm. About 30% thereof (about 404 W/sqm) is reflected back by the upper part of the atmosphere. The rest (960 W/sqm) reaches the Earth's surface. The Earth, however, is not a disc, so this value is divided by 4 (because area ratio of a circle to sphere is 1:4). And so we get 960/4 = 240 W/sqm. According to greenhouse effect theory this amount of energy corresponds to -18º C. However, the real mean temperature of the Earth is  +14º C, not -18º. The difference is 33º C. The mechanism that produces this difference between the actual surface temperature and the effective temperature is due to the atmosphere and is known as the greenhouse effect.
 According to dr Thüne, this calculatuion is wrong. The Earth is a rotating sphere, or in other words a half-sphere, which area is twice as big as  a circle and twice smaller as of a sphere. Therefore the energy of 960 W/sqm reaching the Earth's surface, should be devided not by 4, but by 2. As a result we get then the value of 480 W/sqm which corresponds to about +30º C and not -18º C. According to this calculation, no 'natural greenhouse effect' is needed to reach the actual average temperature of +14º C. What we have instead is a natural cooling effect of ca. 15-16º C (+30º C -> +14º C)!

5. There is no evidence, that CO2 levels and the global mean temperatures are correlated in short time and there is absolute no evidence at all, that rising CO2 concentration is causing this temperature to rise. Just look at this picture:


5. In long term, changes in CO2 levels follow changes in temperature. This means that CO2 rise is caused by the growth of temperature, not the other way round.

6. There is no correlation between fossil fuel emissions and CO2 observed concentration. Look at those 2 graphs:


The growth of CO2 is linear over the whole period. The growth of fossil fuel emissions is not linear (since ca. 2002 it has doubled or even tripled). This is not reflected at all in CO2 levels.

7. Most of CO2 emissions are of natural origin controlled mainly by oceans. The details and this article:

8. CO2 has no influence on the temperature, because it absorbes radiation in ranges corresponding to very low temperatures of ca. minus 60-70 degrees Centigrade. Read what the IR expert Mike Sanicola has to say about it:  read more
