We've Pumped So Much Groundwater That We've Nudged The Earth's Spin
“Observing changes in Earth’s rotational pole is useful for understanding continent-scale water storage variations,” said Ki-Weon Seo, a geophysicist at Seoul National University who led the study. Seo said. “Polar motion data are available from as early as the late 19th century. So, we can potentially use those data to understand continental water storage variations during the last 100 years. Were there any hydrological regime changes resulting from the warming climate? Polar motion could hold the answer.” “I’m very glad to find the unexplained cause of the rotation pole drift,” Seo said. “On the other hand, as a resident of Earth and a father, I’m concerned and surprised to see that pumping groundwater is another source of sea-level rise.”
