This natural phenomenon of the atmosphere are trapping the fraction of solar radiation re-emitted by the Earth is amplified by the excessive release of carbon dioxide, methane (CH4), nitrous oxide (N2O). In the late nineteenth century, the atmosphere contained about 235 Gt of carbon. From 1970, the combustion of fossil fuels is emitted 4.5 Gt of carbon per year, 6 Gt in 1990 and 8 Gt now. Consequently, there is a continued growth in air concentrations of CO2 at the current pace of 1.5 ppm per year.

Measurements at the Mauna Loa Observatory (Hawaii) and the study of air bubbles trapped in polar ice show that the concentration is increased from about 270 ppm in 1850 (beginning of the industrial civilization) to 380 ppm in 2005. Technological civilization has already disrupted the carbon cycle on a global scale. In addition, this increase in atmospheric CO2 is likely to cause significant climate changes. Any increase in the atmospheric concentration automatically induced warming of the lower layers of the troposphere (Encyclopaedia Britannica, 1998). What should disturb the climate system as shown may have multiple “natural” disasters and abnormal weather in recent years around the world.
