<ul><li>Previous studies have shown that the movement of water causes the Earth to rotate slightly differently.</li><li>In the latest study, scientists estimate that humans extracted 2,150 gigatons of water from the Earth's surface between 1993 and 2010, equivalent to a modest 6 mm rise in sea level during that period.</li><li>The new study modeled the observed changes in Earth's polar slip and water movement.</li><li>The researchers found that the location from which the Earth's water was drawn was related to how much the polar position could change.</li></ul>
