Chinese researchers revealed that melting glaciers due to climate change caused shifts in the Earth's mass in the mid-nineties, and they say that this change in mass caused the magnetic poles to rotate and accelerate eastward, as the new study claimed that global temperatures rise Induced by humans are responsible for the shifts in the Earth's magnetic field.
The magnetic north and south pole of the earth are constantly moving, a phenomenon is known as polar wandering, unlike the geographic north and south poles, which remain in a fixed position, and given that the magnetic north and south poles of the earth are turbulent and thrown In different directions due to differences in mass, scientists have to constantly track their location.
Scientists are tracking differences because they can wreak havoc on flight and navigation systems, including smartphone apps that use Global Positioning System (GPS), which rely on accurate magnetic field readings.
Previous research has identified recent movements of the Arctic away from Canada and towards Russia, due to factors such as molten iron in the Earth's outer core, it is known that the Earth's magnetic field is created by the movement of liquid iron in the Earth's outer core, about 1,800 miles under our feet.
The researchers in this study focused particularly on a clear phase of the polar fugue that occurred in the mid-1990s, as the research calculates the total water loss on Earth in the 1990s before the start of NASA's GRACE mission in 2002.
GRACE (Gravity Recovery and Climate Experiment) was a joint mission between NASA and the German Space Center to take detailed measurements of anomalies in the Earth's gravitational field, using a pair of satellites.
Researchers have now found a way to direct the analysis of modern pole tracking back in time to find out why this drift is occurring. Contributions of water loss from polar regions are a major driver of polar erosion, with contributions from water loss in non-polar regions, and all this water loss together explain the change. Eastward in polar drift.
