The body of prehistoric pilose rhinoceros was found, and the largest iceberg in Antarctica disintegrated. What happened to the earth?

In recent decades, global warming has become a topic of concern to all mankind, and with the intensification of global warming, Antarctica and Antarctic continent seem to become fragile.

Prehistoric creatures found in Siberian permafrost. Let's talk about frozen soil first.

Frozen soil is a special landform that appears near the cold secondary area. Only rocks and soil containing ice below 0 degrees Celsius can be called frozen soil.

Siberia, Russia is one of the coldest plains in the world, especially in the northeast of Siberia. The monthly average temperature from June 65438+February to February of the following year is below -45℃, and the lowest temperature exceeds -73℃, so Siberia has the thickest frozen soil in the world, and it is reported that the thickest place reaches1377.3m..

The direct change brought about by global warming is the rise of temperature, which leads to the highest temperature ever recorded in the Siberian Arctic, and more and more ice age creatures have been discovered.

According to Russian Siberian media reports on June 5438+February 30, 2020, in August 2020, researchers excavated a biological remains in the melting permafrost along the Tirekhtyakh River in Yakutia Abiski District, which was covered with short and thick brown hair. After analysis, it was found that this is an extinct long-haired rhinoceros.

Hairy rhinoceros is a large animal in Pleistocene, living 20,000 to 50,000 years ago. It has thick hair. The most striking feature is that it has two horns on its head and a huge hump on its shoulders, which can store fat (hump can protect them from surviving in the extremely cold Arctic).

An adult hairy rhinoceros is usually 3-3.8 meters long and weighs between 1.8-2.7 tons. However, this newly discovered pilose rhinoceros is bigger. Preliminary research found that it was still young when it died, probably in infancy, aged between 3 and 4 years old, and its gender was still unclear. Probably drowned.

It is reported that the corpse of this pilose rhinoceros is the most complete pilose rhinoceros remains found so far, and about 80% of the remains are well preserved, including complete internal organs and teeth. It is worth noting that the last meal was found in its stomach.

The discovery of the dead hairy rhinoceros surprised scientists, because the remains of prehistoric creatures can make scientists re-study the evolutionary history of biology, but at the same time they are worried. After all, the melting of glaciers led to the frequent appearance of prehistoric creatures, and the fusion of glaciers was not a good thing. ...

The disintegration of the largest iceberg in Antarctica (A68) The world's largest iceberg A68 actually fell off the Antarctic in 20 17, with an area of 6,000 square kilometers, equivalent to the size of China and Shanghai.

Iceberg A68 has hardly moved since it was separated from Larsen -C ice shelf for more than a year. According to the satellite images of NASA, it was not until 20 19 that the iceberg A68 left and gradually drifted away from the Antarctic continent under the action of airflow and ocean currents, but it still moved in the Antarctic circle, so the area changed little.

However, it seems that the A68 iceberg no longer belongs to Antarctica. It has gradually accelerated from slow movement, and now it has moved to the edge of Antarctica and split into four icebergs. The largest ship, A68-A, is now heading for South Georgia, where there are habitats for seals, birds and penguins. If they collide, it will be a tragedy. ...

It is no exaggeration to say that with the gradual melting of the A68 iceberg, it will cause local ocean salinity anomalies, destroy ecosystems, and lead to global sea level rise, with disastrous consequences.

The appearance of these ancient creatures and the fusion of glaciers seem to sound an alarm for human beings, and they have to worry about their future development.

The most intuitive manifestation of global warming is the rising temperature, which will not only affect the North and South poles, but also affect the whole earth. For example, problems caused by rising temperatures, such as melting glaciers, rising sea levels and rising global temperatures, will eventually affect the biosphere and even ourselves.

Each of us is a member of the earth, and the situation of the earth is not optimistic now, so each of us should contribute our own strength, start from ourselves and jointly protect our only earth, paying special attention to the changes in the natural environment.
