The new research shows the impact of human activities on the rising sea levels that caused the shift on the poles since the 1990s for almost three decades. Impact of Human Activities in the Rise of Sea Level Groundwater pumped up flows to the sea and redistributed its weight around the world.ĪLSO READ: A Day Was Shorter Than 24 Hours in 2020 Because of Earth Spinning Faster Researchers noted that melting glaciers are accounted the most for the shift but it has also contributed to the pumping up of groundwater that also influenced polar movements. But the new study dates further dates back to the pole shift that extended the link to before the satellite's launch. Moreover, the gravity data from the Grace satellite that was launched in 2002 have linked glacial melting to the polar drift in 20 after increase losses of sea ice. The team of researchers concluded that the poles have shifted about 4 meters in distance due to the accelerated decline of water stored on land because of glacial melting. Scientists found that polar drift shifted from southward to eastward from 1995 to 2020 and was 17 times faster than from 1981 to 1995. However, the new research adds to the information that the loss of hundreds of billions of tons of ice every year resulted in a climate crisis that led to poles moving in new directions. Climate Change Has Made Earth to Shift On Its Axis Since the 1990s Study Finds What Causes a Pole Shift?Īn article in the Bulletin of Atomic Scientists reported that only natural factors like ocean currents and convection of hot rock in deep Earth were considered as causes of a pole shift in the past.
