Discovering the 720,000-year-old ice core could be a

Scientists in Japan recently discovered a 720,000-year-old ice core that could predict the climate situation on Earth.

Specifically, according to scientists from the Polar Research Institute (Japan), "super-aging" ice cores can predict, predict changes such as Earth's temperature, rainfall and wind, the appearance of dust in the dry and windy period through hundreds of thousands of years from the past to the future.

The ice core 720,000 years old has a long shape and has many layers, just like the rings around the tree. Based on these characteristics, scientists analyze ice cores and study environmental conditions, temperature and weather factors that occur when ice layers form.

According to the researchers, the ice core contains full details of Earth's climate change for hundreds of thousands of years. This can help experts make accurate predictions and prophecies about the future climate change situation.

The results of the study found a link between the climate in Antarctica and the Arctic. Data show that when the climate in the Arctic is cool, Antarctica will be hot. The team believes that the inverse relationship between the two poles is caused by a sea current that keeps Europe and North America warm during the winter.

After careful analysis, the team also found that the warming phase in Antarctica corresponds to the climatic changes found in the detached ice core on Greenland - the world's largest island in the Kingdom. Denmark.

The fluctuations begin with a short period of warming and then a long period of frosty temperature reigns.

The team is based on weather simulation models, suggesting that the source of freshwater melting from Greebland ice could slow down the Atlantic meridian convection (AMOC).

It also affects the increase in rainfall, reducing wind power in the Southern hemisphere, leading to a change in the Southern Hemisphere warming and the Northern Hemisphere freezing. AMOC is an extremely important part of the Earth climate model, helping to transport and circulate warm water from the South to the North.

The findings suggest that climate change will melt ice in the Arctic and Greenland, leading to freshwater flow into the ocean. This leads to a disruption of AMOC's balance of freshwater - sea water, causing the Northern Hemisphere to be ice-cold.

According to Ayako Abe-Ouchi, climate scientist at the University of Tokyo and a member of the research team, the problem is that we don't know exactly what AMOC convection can do in the century. next.

Tom Delworth, a geophysicist at Princeton University (USA), commented: "The more we understand what happened to the climate in the past, the more a firm premise for planning and prediction. the future ".

As predicted by Pepijin Bakker, an Earth science at the University of Bremen (Germany) points out that, if the Earth continues to warm up from 4 to 5 degrees in the future, the flow of AMOC convection is actually broken. possible happen in 2030.
