Experts found that sediments, dating back to 90 million years ago, used to be like this in Antarctica!

Antarctica is a very cold area. There are countless glaciers here. The temperature is low all the year round, and few creatures live here. Most scientists can’t stay here for a few days during their exploration. The main reason is that it’s difficult to live in such an extreme climate. Researchers have made an in-depth study of Antarctica and found that 90 million years ago, there was a large-scale temperate rainforest in Antarctica. How can we confirm that?

The main reason is that some people collected sediments near the Songdao glacier in Antarctica, and found that these sediments contain a large number of roots, and the network contains pollen, spores and other residues. Through the identification of these residues, they can be traced back to 90 million years ago. In other words, 90 million years is likely to be covered by vegetation, which sounds strange. If there was a temperate rainforest in Antarctica, it means that the temperature was high at that time. Why is the temperature so low in Antarctica today? Experts found that sediments, dating back to 90 million years ago, used to be like this in Antarctica!

Can the 90 million year old scene of Antarctica be reproduced?

According to relevant scientific reports, in the Middle Cretaceous period, the earth’s surface temperature was very high, especially the sea surface temperature directly reached 35 degrees Celsius. With the flow of ocean currents, the heat would be brought to the north and south polar regions, resulting in higher temperatures in these regions. Many people ask themselves, since temperate rainforests have ever appeared in Antarctica, is there a chance for this kind of scene to reappear? According to relevant signs, the earth’s temperature has increased significantly. If it can’t be alleviated, it means that the earth will become hotter and hotter in the future. There are a lot of melting traces of glaciers in the north and south poles, which may damage the ecosystem.

With the melting of glaciers, many anomalies have emerged. It has been revealed that the appearance of large-scale pink glaciers in the Alps seems to be giving us a dangerous signal and causing a series of problems. Later, scientists found out the reason. It turned out that the rapid propagation of algae was the reason for this scene. The growth of algae will accelerate the melting speed of snow. Generally, the snow is white or light colored. When the sunlight reflects back, the color of the snow will gradually deepen. The melting of these snow will promote the rapid growth of algae, and a scene of blood snow will appear, which will form a vicious circle for a long time.

The Alps are signaling

Scientists are worried about this signal from the Alps. When these glaciers melt, they will bring water to a lot of land and make life more diverse, just like 90 million years ago. For human beings, this is bad news. At present, we should think about how to alleviate these problems. If we can’t find a solution, the future of human beings is worrying.

Climate warming has become an extreme trend, but there is no way to alleviate it. Human beings can solve these problems by planting trees and optimizing the energy structure. Of course, it will take a certain period of time, and it can not be eradicated in the short term. The great change of temperature has already increased the burden of the earth. Everyone can contribute to a better future. How do you feel when you see all kinds of scenes on earth? You can leave a message for interaction.
