The reason the Earth goes through the Ice Age after every 100,000 years

The amount of carbon dioxide absorbed by the ocean plays an important role in making the Ice Age on Earth happen every 100,000 years.

The ocean may be the cause of the Ice Age in the 100,000 year cycle , according to research results published in October 2016 Geology magazine of scientists at Cardiff University, England.

The Earth has experienced many Ice ages in the past 2.6 million years. The last Ice Age ended about 11,500 years ago. Before the "transition between the Renewal" period about a million years ago, the Ice Age on Earth occurred in a cycle of 40,000 years. But then around this time, the cycle increased to 100,000 years, according to the International Business Times.

The team analyzed data from the Deep Sea Drilling Project (DSDP), an international scientific program for drilling and fossil ocean sampling in the ocean floor to study their chemical composition.

They found that a lot of carbon dioxide (CO2) is stored in deep sea during the Ice Age, at intervals of 100,000 years. The ocean may have absorbed a lot of CO ₂ from the atmosphere, causing the Earth's surface temperature to drop because CO ₂ is a greenhouse gas. Meanwhile, the ice sheets on the sea become bigger and the survival time is longer.

However, scientists have not found the exact cause of the ocean absorbing more CO ₂ after every 100,000 years instead of 40,000 years.

"We need to understand all the complex processes of the climate system before giving an accurate answer to the cause of the Ice Age change," said Carrie Lear, lead author of the study. save, said.
