The Great Season Climatic Oscillation and the Global Warming
  The present earth warming up is often explained by the atmosphere gas greenhouse effect. This explanation is in contradiction with the thermodynamics second law. The warming up by greenhouse effect is quite improbable. It is cloud reflection that gives to the earth s ground its 15 degres C mean temperature. Since the reflection of the radiation by gases is negligible, the role of the atmosphere greenhouse gases in the earth warming up by earth radiation reflection loses its importance. We think that natural climatic oscillations contribute more to earth climatic disturbances. The oscillation that we hypothesize to exist has a long period (800 to 1000 years). The glacier melting and regeneration cycles lead to variations in the cold region ocean water density and thermal conductibility according to their salinity. These variations lead one to think about a macro climate oscillating between maximum hot and minimum cold temperatures. This oscillation is materialized by the passages of the planet through hot, mild, and cold eras, leading to the great season climatic oscillation phenomenon (GSCO). Thus, our planet lives four great seasons a great spring, a great summer, a great winter and a great autumn/fall, making a great year embracing our four small classical yearly seasons. The probabilistic character of the parameters that are at the origin of this climatic oscillation makes the long-term prediction less precise but the deterministic tendencies and the resonance phenomena give precious information on our planet climatic future. The present warming up is well interpreted in the frame of the great season climatic oscillation theory.
