 Abstract: The Climate Change Problem is very fashionable today. A huge amount of publications mask (and very successfully) one simple fact, that we ourselves can hardly conceive
• how the "Biosphera machina" operates, or

• whether our Earth Biosphere is unique or whether any other virtual biospheres exist.

In order to answer these questions, we consider the system "biosphere + climate" as a nonlinear system with multiple equilibria. Note that in considering this problem we shall remain within a framework of the most simple zero-dimension and one-dimension models.

The development and realization of these ideas are presented in the chapters 1-5.
Lovelock & Watson (1983) in their Daisy world scenario formalized the Earth description as self-organized system with equilibrium of flows of energy and matter. This model is usually classified as a geophysiology approach. In the chapter 6, the original Daisy world model is extended in some important aspects and concretized to cover realistic biosphere-climate interaction in its structural and functional behaviour. The structural stability, elasticity, regulation ability, and behaviour of the biosphere-climate system under external perturbations have been studied for zero- and one-dimension models.
