Abstract Investigations of global change require information from different fields of geo-sciences. Since global change is accompanied by mass redistribution in the atmosphere, the hydrosphere, and the cryosphere influences on the Earth's rotation can be expected. Studies of relations between climate change and Earth rotation proved a statistical correlation between the variation of different climate parameters and the length of day. But, a physical proof failed. This fact induced us to use the results of theoretical climate models for estimating possible influences on Earth rotation. Therefore, we studied the excitation of polar motion and the Antarctic ice sheet. A further subject, discussed in the paper, is the influence of climate change on the parameters of the seasonal variations of polar motion.
