An analysis of a casual-consecutive model of processes determining the greenhouse
catastrophe development is presented. The whole geobiophysical system is considered,
which includes atmosphere, hydrosphere, litosphere, biosphere, and noosphere. Estimates of
absolute values and characteristic times of the Earth's temperature changes are given.
Some possible measures to low the rate of the greenhouse catastrophe are considered. It is
concluded that there is a serious danger for the human civilazation.
