By then, most likely, a new supercontinent will be formed – Pangea Ultima (the first Pangea existed about 175 million years ago). This will lead to the extinction of our animal world.

Mammals on Earth will disappear: when and why will this happen

Researchers created an estimate using climate model, This takes into account changes in the temperature of the earth’s surface in the new supercontinent, as well as an increase in the intensity of solar radiation and the content of carbon dioxide in the atmosphere. The study was published September 25 in Nature Geoscience.

Supercontinents create conditions that more easily lead to mass extinctions. The formation of supercontinents coincided with 4 of the last 5 mass extinctions in geological history.
– said the study’s first author, climate scientist Alexander Farnsworth from the University of Bristol in Britain.

The foundation of the Earth is far from static and consists of solid slices of rock that lie above the mantle, which in turn float on a turbulent ocean of magma. Over the past 2 billion years, magmatic convection currents have repeatedly stretched these plates, forming oceans and continents, and then reassembling them into supercontinents. This occurs in approximately cycles every 600 million years.

Scientists expect the next supercontinent to form in 250 million years, when the masses of the Earth (most likely at the equator) will come together to form Pangea Ultima. (Pangaea Ultima).

• This is the new continent will be hot: Much of its territory would lack the cooling effect provided by oceans and would also absorb more radiation from an older, more active Sun. Due to volcanic activity, the air will be saturated with much greater amounts of carbon dioxide.
• This would clearly doom mammals to death. Yes, sweat glands and the heat-removing circulatory system cope with high temperatures quite well. And if the temperature exceeds 40 degrees Celsius, these Regulators are broken.
• To find out how habitable Earth will be in the future, scientists turned to a supercomputer climate model that predicts the temperature and humidity at Pangea Ultima. Modeling showed that only 8% of the land It will be suitable for the life of mammals. They will also have little time to adapt to the rapid increase in temperature.

Today, there are very special mammals that can live in regions such as the Sahara. However, it is not yet known whether their descendants will reach Pangea Ultima and dominate it. Maybe reptiles are more suitable? Or is it something completely different?
Farnsworth says.

There is also the possibility of Pangea Ultima. will bring about the end of all living things especially if the temperature gets so high that plants can no longer photosynthesize. However, the adaptation of plants to temperature and the resilience of future marine ecosystems require further research.
