A new study shows that our human pumping and relocating of groundwater has slightly shifted Earth’s mass – thereby slightly changing Earth’s spin – and causing Earth’s rotational axis to increase its rate of wandering. Groundwater withdrawal for agriculture, mining, or household use, for example, has caused a slight-but-noticeable shift of Earth’s mass. That, in turn, has caused the Earth’s rotational pole to wander nearly a meter (approximately a yard) over the last two decades.
