Abstract: Water vapour is itself too strong a greenhouse gas (GHG). However the greenhouse effect will decrease at presence of the clusters formation in water vapour instead of to amplify. As a whole it is possible to consider clusterization as the process resulting from the easing of radiating activity of the atmosphere and the lowering of global temperature. The essence of this anti-greenhouse effect is that the number of centers absorbing and dissipating energy of thermal radiation at the formation of clusters is sharply reduced. Also that the efficiency of absorption of IR radiation is not increased with the growth of cluster size. Additional easing of radiating activity of the atmosphere occurs as a result of absorption of greenhouse gases‘ molecules such as CO2, CH4, and N2O by water clusters. Water clusters that absorbed these molecules, as a rule, reduce the efficiency of Earth radiation absorption and strengthen the power of IR emission radiation. The increase of the water vapour content in atmosphere at the present condition of an atmosphere results in amplification of a greenhouse effect, but not in direct ratio to quantity added vapour. Now clusters are formed and they reduce a greenhouse effect. However there can come the moment of such warming in atmosphere, that clusters will not be formed. It will result to significant jump of global temperature and its further very fast growth, i.e. to catastrophe. The autoregulation of the atmosphere composition is due to the formation of water clusters and their subsequent capture of greenhouse gas molecules is, as a rule, ignored in the estimation of the Earth's radiation balance.
