What in the world is powerful enough to alter the Earth's rotation? You guessed it - WATER!

Earth’s rotation rate is changing after 3.6 million years due to melting polar ice sheets and glaciers that are redistributing huge amounts of water around the planet.

As a result, days are getting longer by ~ 1.33 milliseconds per century, and this is important b/c GPS satellites, spacecraft, and scientific instruments all rely on extremely accurate measurements of Earth’s rotation. https://tech.supercarblondie.com/earth-rotation-rate-changing-affect-gps/ #Earth #EarthRotation #ClimateChange #PolarIceSheets #Gaciers #Cceans #SeaLevelRising #Water #Space #Satellites #Navigation #AirTravel #SpaceCraft #SpaceFlight
