Jakarta, CNBC Indonesia – Scientists are studying how the Earth’s rotation affects changes in Earth’s climate and natural conditions. For billions of years, the Earth rotated in the same direction as the sun and scientists modeled versions of the Earth that rotated in the opposite direction.
Quoted from Live Science, Florian Ziemen, co-creator of the simulation and researcher from the Max Planck Institute for Meteorology in Germany said if the rotation occurs in reverse it maintains all the main topographic characteristics such as the size, shape and position of the continents and oceans, while creating the same set of conditions. , it will create a different interaction between circulation and topography.
If the Earth rotated counterclockwise it would be like resetting ocean currents and winds and interacting with the continents in a different way. This is also generating entirely new climatic conditions around the world, according to the researchers in the project review.
The researchers also simulated what would happen if the Earth rotated backwards or in the opposite direction. Overall, the researchers found that the Earth that rotates backwards is the greener Earth.
Global desert coverage has shrunk from about 16 million square miles or 42 million square kilometers to about 12 million square miles or 31 million square km. Grass grows in more than half of the former desert area, and woody plants appear to cover the other half.
This version of Earth’s vegetation also stores more carbon than our spinning Earth, the researchers found. However, deserts emerge where they have never been before, such as in the southeastern United States, southern Brazil and Argentina, and northern China.
Rotational changes also reverse global wind patterns, bringing temperature changes to the subtropics and middle latitudes; the western zone of the continent cools as the eastern boundary warms, and winters become significantly colder in northwestern Europe. Ocean currents also change direction, warming the northeastern boundary and cooling the western boundary.
In the simulation, the AMOC—the ocean current responsible for transporting heat around the world—disappeared from the Atlantic Ocean, but a similar and slightly stronger current appeared in the Pacific, carrying heat to eastern Russia. According to Ziemen, this result is unusual and previously in simulations of the reverse rotation of the Earth this change has never been seen.
“But because AMOC is the result of many complex interactions in the climate system, there could be many reasons for this difference,” he said.
But for Ziemen, the greening of the Sahara is the most exciting change that appears in the most recent reverse rotation model of the Earth.
“Seeing a green Sahara in our model made me think about the reasons why we have desert in the Sahara. It’s thinking about this most basic question that fascinated me about this project,” says Ziemen.
The planet rotates backwards on Venus. On this planet, dubbed the Morning Star or Evening Star, the sun rises from the west and sets in the east.
On Earth, the Sun, Moon, planets and stars all rise in the east and set in the west. The reason is that the earth rotates towards the east, as quoted from the official NASA website.
