BMKG experts explain the axis of the earth and climate change



Jakarta, CNN Indonesia –

Recent research shows that climate change is making a difference Earth as, 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 redistribution of water has changed the location of the North and South Poles since the mid-1990s.

Researchers say that the Earth’s axis began to shift drastically in 1995, so the direction of the pole shift changed and became very fast. Melting ice changes the way the earth’s weight is distributed.




By the mid-1990s, satellite data showed that the poles were slowly moving south. But then it turns left and starts accelerating to the east at a faster pace, moving about a tenth of an inch per year.

Meteorology, Climatology and Geophysics (BMKG)’s Climatology Deputies Herizal stated that the shift in the Earth’s axis is actually causing climate change.

He said that the angle of the earth as to the true north is said to affect the amount of radiation received by places on the earth’s surface, known as the eccentricity and obligatory effects.

Herizal explained that a major change in eccentricity as commitments will significantly affect the budget energy balance on the earth’s surface, which in turn will affect the climate system.

“This commitment variability is known as a 33-year cycle,” Herizal said CNNIndonesia.com, Friday (30/4).

On the other hand, Herizal also explains the direct relationship between melting glaciers and the increasingly tilted ones of the Earth. He said that if the Earth’s climate system changes, it will change all the components of the Earth’s climate system that include 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, increasing the world sea level by 0.4 inches. The rate of payment has increased sevenfold, from 36 billion tonnes per year in the 1990s to 280 billion tonnes per year in the last decades.

The melting of Antarctic glaciers also accelerated in the 1980s. Antarctica loses 40 billion tons of ice every year. In recent decades, this figure has risen to an average of 252 billion tons per year.

The axis of rotation of the Earth is not straight up and down like the axes of Mercury or Jupiter. Conversely, the earth’s axis is tilted at an angle of 23.5 degrees.

Therefore, the northern and southern hemispheres receive different amounts of sunlight at different times of the year, which is also why the earth has seasons.

Recent changes in the Earth’s axis would not affect the daily life of man, but it could change the time of day a bit.

It takes the Earth less than 24 hours to complete one rotation. But a pivot change can add milliseconds to that lap time, making a day a little longer.
