Earth's Rotation Slows, Days Lengthen
Human-driven climate change is dramatically slowing Earth's rotation by melting glaciers and ice sheets, a redistribution of mass that is lengthening days by an unprecedented 1.33 milliseconds per century—a rate not seen in millions of years. This subtle yet significant shift could soon impact critical technologies like GPS and global timekeeping, with projections indicating further acceleration if greenhouse gas emissions continue unchecked.
