Jakarta, CNBC Indonesia – A study reveals that extreme climate change has shifted the Earth’s axis. In the latest research, climate change has increased the melting of glaciers in arctic regions for decades.
Research published in the journal Geophysical Research Letters states that the large amount of water redistribution causes the location of the north and south poles to shift to the east since the mid-1990s.
Researchers say that the earth’s axis began to shift drastically in 1995 so that the direction of the pole shift changed and became very fast. Melting ice changes how Earth’s weight is distributed.
Prior to the mid-1990s, satellite data showed the poles were moving slowly south. But then it turns left and starts shifting east at an accelerating rate, moving about a tenth of an inch per year.
Deputy for Climatology of the Meteorology, Climatology and Geophysics Agency (BMKG), Herizal, conveyed that the shift in the earth’s axis was actually causing climate change.
He said the angle of the earth’s axis to true north is said to have an influence on the amount of radiation received by places on the earth’s surface, known as the eccentricity and obliguity effects.
Herizal explained that a significant change in eccentricity or obliguity will significantly affect the budged energy balance on the earth’s surface which in turn affects the climate system.
“Obliguity variability is known as a 33 year cycle,” said Herizal.
On the other hand, Herizal also explains the direct relationship between melting glaciers and the increasingly tilted axis of the earth. He said that when the Earth’s climate system changes, it will change all components of the Earth’s climate system which consists of the atmosphere, hydrosphere (including oceans), cryosphere (including glaciers), and biosphere (land).
According to Business Insider, Greenland has lost more than 4.2 trillion tonnes of ice since 1992, which raised global sea levels by 0.4 inches. The rate of disbursement has increased sevenfold, from 36 billion tonnes per year in the 1990s to 280 billion tonnes per year in the last decade.
Antarctic glacier melting is also said to have accelerated in the 1980s. Antarctica loses 40 billion tonnes of ice every year. In the past decade, this figure has soared to an average of 252 billion tonnes per year.
