The climate instability problem
It is shown, based on the analysis of the physical behaviour of the terrestrial greenhouse effect, that the climate with an extensive liquid hydrosphere like that of Earth is physically unstable with respect to spontaneous transitions to either of the two stable but life-incompatible states, that of complete evaporation of the hydrosphere with global mean surface temperature higher than +400 oC and that of complete glaciation of the planet with temperature lower than −80 oC. The available paleodata testify for a stable maintenance of the values of global mean surface temperatures within the interval 5-25 oC during the last seven hundred million years. In the absence of a physical mechanism that could ensure such a stability, the observed sustainability of the life-compatible values of surface temperature can be only explained by accepting the existence of the biotic regulation of the global cycle of water (the major greenhouse gas on Earth) and surface temperature.
