Unsolved: Climate Change Problem

The Zero-dimensional Energy Balance Model is introduced to calculate courses of global mean temperature increases for the stationary higher limit values of 1.5 0 C, 2.0 0 C and 3.0 0 C compared to the pre-industrial time. In particular, mean stationary temperatures for sea surface, land surface and entire surface of the earth are calculated and compared, also with temperature anomalies. The problem of the Carbon budget will be discussed. Its solution is a real challenge for mankind.
