#Has shifted earth axis driver
The team found that the "contributions of water loss from the polar regions is the main driver of polar drift, with contributions from water loss in non polar regions." glaciers, changed, according to SciTechDaily. To check their theory, the scientists in the study calculated how water stored on land, i.e. "The second scenario assumes that it changed from observed glacier ice melting."Īccording to the study, only the second scenario, along with the atmosphere, oceans, and solid Earth, "agrees with the polar motion during the period of 1981-2020." This new finding, which posits that "the accelerated terrestrial water storage decline resulting from the glacial ice melting is thus the main driver of the rapid polar drift toward the east after the 1990s," indicates that a close relationship between the movement of Earth's poles and climate change exists.Īccording to SciTechDaily, the direction of polar drift shifted from southbound to eastbound in 1995, and from 1995 to 2020, the average speed of the polar drift, "increased about 17 times the average speed recorded from 1981 to 1995." "One scenario assumes that the terrestrial water storage change throughout the entire study period (1981-2020) is similar to that observed recently (2002-2020)," the study reads. The study was published in the peer-reviewed journal Geophysical Research Letters, a publication of the American Geophysical Union.To determine how this might have happened, scientists observed two possible theories and their outcomes in relation to the Earth's axis. Humphrey told the Guardian that this "tells you how strong this mass change is – it's so big that it can change the axis of the Earth."īut the movement of the Earth’s axis is not large enough to affect daily life, he said: It could change the length of a day, but only by milliseconds. The same thing happens to the Earth as weight is shifted from one area to the other. If the weight of a top shifts, the spinning top would lean and wobble as its rotational axis changes. In the past, only natural factors such as ocean currents and the convection of hot rock deep in the planet contributed to the pole drift, the Guardian said.Ĭlimate scientist Vincent Humphrey of the University of Zurich, Switzerland, who was not involved in the new research, said the Earth spins around its axis like a top. The massive melting of glaciers as a result of global heating has caused marked shifts in the Earth’s axis of rotation since the 1990s, research has. Nevertheless, NASA claims that the shift is an occurrence that had taken place over tens of thousands of years. In addition to melting glaciers, the pumping of groundwater has contributed to the shift in Earth's axis, the study said. The Earth's axis has been proven to be shifted Will there be global warming or what is happening to nature The channel lists natural disasters such as: 1) Emergency geological situations. Inuit elders says the Earths axis has shifted The International Business Times reiterates NASA’s claim that this phenomenon is due to global warming. Since 1980, each pole has moved roughly 13 feet. More Earth science: Scientists say Earth is spinning faster than it has in decades “The faster ice melting under global warming was the most likely cause of the directional change of the polar drift in the 1990s,” study co-author Shanshan Deng of the Institute of Geographic Sciences and Natural Resources Research at the Chinese Academy of Sciences said in a statement.
