  The variations of water density and thermal conductivity of the oceans cold
region waters according to their salinity lead to suggest an hypothesis of an
oscillating climate between two extreme positions: a maximum of hot
temperatures and a minimum of cold ones. It will be shown that the distance
separating the surface hot streams from the depth cold ones oscillate between
two limit values linked to the optimal melting and regeneration glaciers. The
melting and regeneration glaciers cycle leads to the Great Saison Climatic
Oscillations phenomenon necessary to the regeneration of fresh water resources
of our planet.
