negative, almost canceling the pure positive contribution of sea level, Foi, whereas both

V\\ and Vol are close to zero during stage 5,

To illustrate the efficiency of this factor separation method, it can be applied to the results otained by tianopolski ct al. (1998) and discussed in section 8.3, Their simulation using an atmosphere-ocean-vegetation model demonstrates a strong synergism between the climate components. Tables 8.4a and 8.4b show that these interactions arc larger than the pure contribution of any of the components, the importance of the ocean and vegetation subsystems depending on the climatic parameter under consideration. In addition to the synergism, the warming of the boreal w inter, for example, is caused mainly by the ocean, whereas it is caused by the vegetation for the summer and annual means. The warming (up to 3 to 4 C in the northern continental areas in winter and
