Shifting water weight is changing the way Earth’s poles move around, a new study indicates. While Earth’s axis periodically shifts by itself, the effect is being exacerbated by human activity’s effect on climate, researchers found. Melting glaciers and changes in land-based groundwater storage have skewed it even further, the American Geophysical Union reported in a study published last week in its journal Geophysical Research Letters.
