Storage of water in artificial reservoirs shifted Earth’s rotational poles by 113 cm (44 inches) and caused a 21 mm (0.83 inches) global sea level drop between 1835 and 2011, according to new research published in Geophysical Research Letters on 23 May, 2025.
Rice University geophysicists have determined Earth shifted relative to its spin axis within the past 12 million years, which caused Greenland to move far enough toward the north pole to kick off the ice age that began about 3.2 million years ago. The study is based…
