  • Exactly.

    In fact the purpose of the paper is to examine the effect of groundwater pumping on sea level. There are two competing hypotheses: (1) pumping decreases sea level by sequestering water, and (2) pumping increases sea level for complex reasons.

    The authors noted that these hypotheses would imply different small changes in axis tilt. They measured axis tilt and found it supports hypothesis 2. The small change in axis tilt is simply a clever way to answer the question, it has no other impact on our life.
