The North Pole can move up to 90 feet – it can cause destruction for satellite navigation, scientists warned
It is the reference point for navigation systems all over the world and one of the most famous places in the world.
However, scientists say that the Geographical North Pole is in motion and can slide about 90 feet (27 meters (27 meters) until 2100.
As the polar ice layers melt faster in the heated climate, the mass of the Earth is redistributed and slightly changes the rotation axis of our planet.
Although these changes are small on the planetary scale, scientists warn that they can cause destruction for satellite navigation.
As it opens the world axis, the changes in the oceans, in the atmosphere and molten mantle cause the planet to shake like a rotating hill.
Although most of the planet’s shakes are regular and predictable, scientists from Eth Zurich have found that human -based changes will soon be more outbreak than natural changes.
Since satellites and deep space telescopes solve their position by referring to the world’s rotation axis, any changes in the North Pole may cause serious problems.
Chief writer Dr Mostafa Kiani Shahvandi, now at the University of Vienna, said Mailonline could cause mistakes to cause a few meters to a hundred meters’.
According to scientists, the world’s north pole is in motion and it can vary up to 27 meters by 2100
Like anything that rotates on the axis, it causes the Earth to slip on the axis of large changes in the mass distribution.
Often, this is a normal and predictable process caused by factors such as regular loops of ocean currents.
However, as the planet’s ice layers and glaciers melt, this causes scientists to be redistributed faster than they have observed in the past, which causes the pole to change.
Dr. Shahvandi and his joint writer measured the movement of the poles between 1908 and 2000, and compared this with ice -melting projections to see how much they could move in the future.
In the worst scenario, where greenhouse gas emissions are not reduced, the dramatic melting of the ice sheets will have moved the poles between 89 feet between 1900-2100.
In a more optimistic scenario where greenhouse gas emissions are reduced, the North Pole will still move up to 12 meters.
For now, human -induced effects do not move the poles as much as natural causes.
The biggest source of the polar change is now from the earth that returns from the last ice age.
As the ice caps melt in the heated climate, the weight of the Earth is redistributed around the planet. Like a rotating top, this change changes the axis in which the world has returned and moves the Geographical North Pole.
In the worst scenario (red) climate change can trigger the polar to move 89 feet between 1900-2100. In a more optimistic scenario (green) where greenhouse gas emissions are reduced, the North Pole will still move 12 meters (12 meters)
During the ice age, the Earth’s bark sank under the weight of the glaciers and rose since they were melted and redistributed the weight of the planet.
Although the last ice age has ended 10,000 years ago, the effects of rebounds can still be seen in the natural shift of the North Pole.
In the near future, however, scientists say that human -induced climate change will make the greatest contribution to the ice age Ribunda.
Dr. Shahvandi says: ‘Currently, the natural processes are dominated by the polar movement, but if the climate change continues and the ice layers are increasingly melting, human -based climate change will certainly dominate in the last decade of the 21st century.’
Recently, scientists warned that the world’s sea ice – frozen ocean water on the north and south poles has fallen to a record level.
Last month, the Arctic Sea Ice reached its lowest level for March in a 47 -year satellite record.
The Arctic covered a smaller area from the average sea ice and marked the fourth month in a row when the width of the sea ice was recorded as record -breaking miscarriages.
Similarly, Antarctica Sea Ice reached the lowest fourth month level for March and stood 24 percent lower than the average.
The biggest contributions to the shift were Antarctica Ice layer and Greenland Ice layer (in the picture) melting at the ratio of acceleration
This graph shows that the melting of the Greenland ice layer can replace the pole on X (top) and y (lower) axes up to 2100. The red line shows the worst scenario where emissions are not reduced and the blue line shows the more optimistic scenario.
This can cause serious problems for space -based telescopes such as James Webb Space Telescope (Picture), which uses satellite navigation and the world’s axis as a reference point for navigation. This may cause errors on a mileage scale
Researchers have discovered that the biggest sources of the polar shift were the melting of Greenland ice layer and Antarctica ice layer.
If this change persists, it may probably cause problems for sensitive navigation systems of satellites and space telescopes such as James Webb space telescope.
In his articles published in the journal Geophysical Research Letters, researchers write: ‘Since the foresight of the polar movement is very important for applications such as the orientation of deep space telescopes, the prediction of the polar movement under climate change may affect the operational sensitivity of such practices.’
It would be bad for navigation systems on earth, but it would be even more dangerous for the spacecraft, because it will be difficult to solve their full position.
Dr Shahvandi said that this could create ‘mileage’ errors that investigate distant planets for the increase in spacecraft.
