☆ Human activities are changing Earth's spin so much that it might affect how we keep time

Polar ice melt driven by climate change is affecting Earth's rotation, according to new research. A human-driven change in the Earth's rotation has never been seen before, and may affect computing. DrPixel/Getty ImagesDon't worry — this change in Earth's rotation won't be catastrophic. Denis Tangney Jr./Getty ImagesAs a result, scientists predict that we would need the first-ever negative leap second by 2026. iStock / Getty Images PlusThere are three main mechanisms that control the Earth's spin:One is tidal friction, or the interaction between moving ocean water and the ocean floor, which slows Earth's rotation.

☆ A Faster Spinning Earth May Cause Timekeepers to Subtract a Second From World Clocks

Clocks may have to skip a second — called a “negative leap second” — around 2029, a study in the journal Nature said Wednesday. “We are headed toward a negative leap second," said Dennis McCarthy, retired director of time for the U.S. Without the effect of melting ice, Earth would need that negative leap second in 2026 instead of 2029, Agnew calculated. In 2012, some computer systems mishandled the leap second, causing problems for Reddit, Linux, Qantas Airlines and others, experts said. Then add in the “weird” effect of subtracting, not adding a leap second, Agnew said.

☆ Polar ice is melting and changing Earth’s rotation. It’s messing with time itself
  + stars: | 2024-03-27 | by ( Laura Paddison | Rachel Ramirez | ) edition.cnn.com   time to read: +5 min
Exactly when that will happen is being influenced by humans, according to a new study, as melting polar ice alters the Earth’s rotation and changes time itself. The hours and minutes that dictate our days are determined by Earth’s rotation. But after a long trend of slowing, the Earth’s rotation is now speeding up. Melting polar ice is slowing the impact on Earth’s rotation and has delayed the date by three years, pushing it from 2026 to 2029, the report found. Changes in Earth’s rotation over the long term have been dominated by the friction of the tides on the ocean floor — which has slowed down its rotation.
