Ice Age is the period when the entire earth is covered with ice. Even in the hot areas of the equator, ice sheets can be seen. In such a situation, the question becomes interesting that what would be the temperature during that period!
Our scientists consider ice ages to be very important events on Earth. They also believe that the last ice age had a huge impact on the Earth’s climate and other things. Even the mysteries of today’s climate change and its effects can be traced back to the events of the Ice Age. But during the Ice Age, how cold the Earth was, how much the temperature here had dropped. This has also been detected.
The last ice age occurred about 20 thousand years ago. Scientists give special importance to the temperature at that time. It is called the Last Glacial Maximum. To calculate this, researchers at the University of Arizona used fossils of small organisms in the oceans and climate models.
During that period, areas of Europe, Asia and both the American continents were covered with snow. The situation became such that the snow did not melt even in summer. During the Ice Age, some areas were much colder than today. The average temperature in the Arctic was 14 degrees below average.
Researchers came to know about that era from the fat of fossils of small creatures living in water. Such organisms are sensitive to changes in water temperature. It was only with the help of this information in climate model simulation that the temperature of the ice age could be determined.
This period has been being researched for a long time and many types of studies are being done. Researchers say that although a lot of information has been received about the Ice Age, it was not an easy task to know how cold the Ice Age actually was and what kind of temperature was there then.
The average global temperature at that time is called the last glacial maximum. Scientists from Arizona University have calculated this temperature. The temperature used to be around 7 degrees Celsius between 22 to 19 thousand years ago and it is only about 8 degrees Celsius less than the average temperature of today’s era.
The last ice age that existed lasted about 11 thousand years ago. In this, many changes were seen in large mammals. He had adapted himself to the changes. This was the same time when ancient humans entered North America from Siberia via Alaska.
The study published in Nature Journal also states that this kind of information about the Ice Age can tell about the effects and changes of climate change during that period. From this we can know about today’s climate change.
The Ice Age is seen as an important document about the changes on Earth and its impact on life. The current climate changes may also become the basis for another ice age for the Earth in the future. But it may take thousands of years for this to happen.
