Earth's wobble on its axis
WebSep 25, 2024 · Over the past century, that wobble has largely drifted west at a pace of 10.5 centimetres (4 inches) a year, changing its location by about 10 metres. But the path it takes isn't a neat one. Around the turn of the millennium, the drifting spin axis dog-legged back unexpectedly at a pace of about 17 (7 inches) centimetres a year. WebApr 28, 2024 · Earth's axis has shifted since the 1990s, thanks to climate change. As glaciers melt, water mass redistributes, causing shifts in the planet's axis. (Image credit: NASA/JPL-Caltech)
