Scientists warn of new impact of climate change on Earth

antiquities Global warmingAlthough they often appear Extreme weather eventsIt also manifests itself in less obvious but equally important ways. Scientists warn of something new and disturbing impact climate change It could change the functioning of the planet and its systems in ways not yet understood. Modern Studying The follower ETH Zurich Swiss University He revealed how Global warming is Cause Gradual shift in the Earth’s axis of rotationa phenomenon known as Polar motion, a fundamental phenomenon that regulates many natural processes.

Melting glaciers at the poles not only raise sea levels, but also redistribute Earth’s mass toward the equator. This global shift has a direct impact on the planet’s rotation. According to the research, The movement of water from the poles toward the tropics changes the shape and distribution of the Earth’s weight, slowing its rotation.

This slowdown, although minimal, It is enough to extend the length of days by a few milliseconds. Redistribute the mass also. It causes the Earth to become thicker at the equator, making it more “massive” in that region.

Benedict SogaProfessor of Spatial Geodesy at ETH ZurichHe explained that these changes are similar to the movements of a skater who changes his speed by changing the position of his arms. These disturbances not only affect rotation, but can also have unexpected consequences for the global environment.

To better understand this phenomenon, the Swiss university team used Advanced AI Modelsknown as Physics-Informed Neural NetworksThese models have allowed researchers to create a more accurate and detailed representation of polar motion, taking into account not only changes on the surface, such as melting ice, but also the planet’s internal dynamics, such as movements in the core and mantle. This innovative approach has provided a more complete view of how these different factors interact and contribute to the shift in Earth’s axis of rotation, providing more accurate predictions of how this phenomenon will evolve in the future.

For billions of years, moon The main force affecting rotation was land And in the length of our days. The tidal effect, caused by the moon’s gravitational pull, has been gradually and steadily lengthening the length of the day. However, climate change caused by human activity is beginning to compete with this natural force. Scientists have discovered that melting polar caps, caused by global warming, are pushing meltwater toward the Earth’s equator. landchange your balance.

Benedict Soga, Professor of Space Geodesy at ETH Zurich Express to Interesting engineering:Climate change is causing the Earth’s axis of rotation to shift.Conservation of angular momentum feedback also appears to change the dynamics of the Earth’s interior. This phenomenon can change our environment in ways that are still not well understood but may be important.

The increasing length of the day is another annoying consequence of the Earth’s changing rotation.According to a report by a pot“From 2000 to 2018, the rate of increase in day length due to ice and groundwater movement was 1.33 milliseconds per century—faster than any period in the past 100 years.” Although this increase is imperceptible to humans, it is a tangible indicator of how human activities are affecting the physical behavior of the planet.

There are many measures to mitigate the rise in global temperatures. Using or investing in renewable energy is an excellent way to contribute to the change. a pot He pointed out that “Global warming is caused by dirty energies like coal and oil.” It causes a gradual shift in the Earth’s axis of rotation, a phenomenon known as Polar movementReducing the use of these energy sources could reduce their impact on global temperatures.

Another vital initiative is to educate yourself about circular economies and how to reduce waste and contribute less to industrial production and shipping. Companies such as Trashi It rewards those who participate in these practices, and promotes a more sustainable economy.

Global warming poses many challenges, both visible and hidden, that require immediate attention and collective action. Staying informed and adopting sustainable practices is essential to combat this phenomenon and ensure a safer future for the planet.
