We draw attention to the length of day (LOD) and amplitude of the Chandler wobble changes, which show 70-year modulations similar to what can be observed in the mean Earth temperature and sea level. We analyze Chandler wobble phase and amplitude changes, as well as LOD, and their excitation sources, trying to bridge this traditional subject of geodesy with contemporary climatological observations over ocean, atmosphere, and land mass transport. We believe, our epoch of precise observations of the Earth system is already providing an evidence of interconnection between climate processes and Earth rotation changes.
