Global Warming and CO2 Emissions
Let us begin with some facts we think are established:
1) Carbon dioxide is neither toxic, nor a pollutant. Its emission is an inevitable and necessary result of any combustion with composites of carbon (oil refined, coals, natural gas, etc). It is also an essential gas to life on earth because when they breathe, all living beings inhale a mixture of oxygen and CO2, and then exhale the latter.
2) There is no evidence that CO2 emissions of anthropogenic origin (i.e., man-made, which excludes all other natural emissions of this gas) have any significant effect on global warming. Many scientists consider that the human contribution to global CO2 emissions occurring on the planet is absolutely negligible.
3) Empirical data has shown that the renowned global warming foreseen by computer models used by the Intergovernmental Panel on Climate Change (IPCC) has not been happening since 1998. So, opportunistically, they have changed the expression "global warming" – which no longer corresponded to the factual truth – to the more ambiguous term of "climate change" (which always existed throughout the history of the Earth).
4) Computer models are themselves unreliable. The modelling theory tells us that, to be useful, models should be relatively simple, with a limited number of variables. Trying to apply modelling to the climate is a pathless effort because then the number of variables (and the assumptions that have to be made) is huge. In climatology, little use can be obtained from computer modelling, no matter how powerful the computers may be (although the same does not apply to the weather forecast).
5) It becomes even worse if a bad method such as computer modelling is based on an obsolete theory. This is precisely what is happening with the climatologic models used by IPCC, designed in the early twentieth century (thus, before the existence of Meteorological Satellites). The modern climatologic theory was established by the great French scientist Marcel Leroux (1938-2008), from the Université Jean Moulin in Lyon. Professor Marcel Leroux's opinion about this supposed warming is summarized in his article "A scientific sham ":
6) The IPCC is not an organization of scientists but of bureaucrats appointed by governments and usually well-paid. It is a lie that the IPCC has three thousand scientists specialized in climate, as has been so often proclaimed. And it is also a lie to say that there is a "scientific consensus" in regard to the heating dogma.
7) It would not be bad for mankind if there was some degree of global warming on Earth. Many regions of the world would start having fruitful farming. Greenland, for example – the "Green Earth" as the Vikings called it – had agriculture in the Medieval Warm Period. One might even say that the cradle of Western civilization on Earth was in an extremely warm climates: Mesopotamia (now Iraq) between the Tigris and the Euphrates. The Egyptian and Aztec civilizations flourished in warm climates.
