The Sun Drift
The General Conference on Weights and Measures opens on Tuesday, October 13. The setting is the Palais des Congrès de Versailles, a short walk from the palace that Louis XIV built under the emblem of the sun. Delegates from the states party to the Metre Convention will spend three days on the business of measurement. Near the close of the meeting, at the twenty-fifth item of the agenda, they will vote on a paper called Draft Resolution C. The paper proposes that on May 20, 2027, the world's civil clock stop answering to the sky. Resolutions reach this conference after years of committee negotiation, and they are usually adopted as drafted. If this one carries, a deference that began on June 30, 1972, with the first leap second, comes to an end. […]#earthrotation — Public Fediverse posts

Coriolis Effect ✍️
It explains why objects moving across a rotating world seem to curve from their straight path, even when no visible force pushes them sideways. Imagine throwing a ball straight across a spinning merry-go-round. To someone standing still outside, the ball travels in a straight line. But to someone riding the spinning platform, the ball appears to bend away from its path.
The same thing happens on Earth because our planet is constantly rotating beneath everything that moves. Air currents, ocean flows, and even long-range projectiles travel over a surface that is turning while they move. This creates the illusion of a sideways force, known as the Coriolis effect.
In the Northern Hemisphere, moving objects appear to bend to the right, while in the Southern Hemisphere they bend to the left. The effect grows stronger over larger distances and faster motions, but becomes almost unnoticeable in small, everyday movements.
Scientists use this effect to understand the spinning of hurricanes, the paths of trade winds, and the circulation of oceans. It reveals that motion is not always as simple as it seems when the ground beneath us is constantly in motion itself.

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

Human-driven climate change is slowing Earth’s rotation at a rate not seen in 3.6 million years. As melting ice shifts mass toward the equator, the planet's spin is dragging enough to lengthen our days by 1.33ms per century, potentially outpacing the Moon's influence.

China's Three Gorges Dam, the world's largest hydroelectric power project, is more than just an engineering marvel—it's so massive that it has even affected Earth's rotation. Built on the Yangtze River, this colossal structure stands as one of the most remarkable human-made feats, showcasing the incredible scale of modern engineering.

27 mars #EarthRotation — Le réchauffement climatique ralentit la rotation de la Terre. La masse des calottes glaciaires de plusieurs kilomètres d’épaisseur qui recouvrent le Groenland et l’Antarctique exerce une forte attraction gravitationnelle sur les océans. À mesure que les calottes glaciaires fondent, toute cette masse s’éloigne des pôles et se dirige vers l’équateur, réduisant ainsi cette attraction et provoquant également un ralentissement de la rotation de la Terre.
