Scientists have calculated Earth’s ICE AGE Temperature: will you survive?

Introduction:

The global temperature which was calculated on average during the last period that was known as the Glacial maximum. This period was around 23000 to 19000 years ago. The temperature calculated during this time was 46 degrees Fahrenheit. It was about 13 degrees Fahrenheit cooler than the temperature of 2019.
A very well known period among the scientists was the Ice Age. This period spanned from about 115,000 to 11,000 years ago. The Earth saw the age of very large mammals such as the woolly rhinos, mammoths, saber-toothed cats, and mastodons.

With the help of fossils and models of the climate, the scientists have found exactly how cool the Earth used to get during the Ice Age. The time when huge ice sheets were covered over Europe and North and South Americas.

Research Results:

The average temperature was about 46 degrees Fahrenheit. However, certain places were cooler than the average global.
The researchers reached this result by studying the chemical measurements on very tiny fossils and the preserved fats structure of the creatures present during that time.

These research results were termed as “temperature proxy”. During the Ice Age, the large mammals that lived on the surface of Earth were adapted to the chilly conditions on the Earth.
Humans first entered the land of North America during the Ice Age only. They crossed the tiny land bridge that was present between Siberia and Alaska during that time. There used to be an icy bridge at the place of Bering Strait. And the central region of Alaska was not very cold during that time. Hence, making it a nice place to live.

The scientists were guided by the plankton fossils and the climate models for their research. The polar region was as usual very cold during that time too.

Conclusion:

The mass extinction of the species around the globe had one of its causes due to the mass hunting of humans. The effect of the Ice Age was certainly different across the different places on Earth.
About 14000 years ago, the Earth again saw the growth of plants and the increase in temperature. This resulted in more dense and versatile levels of biodiversity on this planet.
