The melting of polar ice due to climate change is slowing down the Earth's rotation on its axis. Scientists report that this process is lengthening the day by 1.33 milliseconds per century, reaching a level not seen in the last 3.6 million years.
According to researchers at the University of Vienna and ETH Zurich, the magnitude of the change in Earth's rotational energy is equivalent to the impact of a magnitude 9 earthquake. Experts emphasize that this situation shows the growing impact of human activity on the planet's systems.
Forecasts suggest that by the end of the century, climate change will become the primary factor influencing the lengthening of the day, potentially even surpassing the gravitational influence of the Moon. This could pose certain risks for high-precision systems like GPS.
Previous studies have shown that melting glaciers are also changing the shape of the Earth. Scientists believe these processes could have a more significant impact on the planet's dynamics in the future.
