A study showed that mammals have 250 million years left to live. This is because solar energy is becoming more powerful and carbon dioxide in the atmosphere is also increasing. It is predicted that it will become difficult for mammals to survive if the global temperature rises to a maximum of 70 degrees Celsius, creating a ‘hot environment’.
Professor Alexander Farnsworth’s team at the University of Bristol in the UK predicted the survival period of mammals based on data on continental movements and changes in the chemical composition of the atmosphere. The research paper was published in the international academic journal ‘Nature Geoscience’ on the 25th. The research team predicted that the climate would change significantly due to three factors: stronger solar energy, changes in continental topography, and increased carbon dioxide. Professor Farnsworth described it as “a triple whammy that makes survival of mammals impossible.”
During a star’s life cycle, the sun gets hotter and hotter, eventually running out of hydrogen and exploding. Previously, scientists had published research results showing that this period was about 7.6 billion years later. According to Professor Farnsworth’s calculations, the energy emitted by the sun is increasing by 1% every 110 million years.
The researchers estimated that mammals would have disappeared much earlier. The simulation results showed that a supercontinent would be formed 250 million years later, with the land uniting around the equator. The combined land becomes larger and thicker. More heat accumulates in the mantle beneath the earth. This can cause the surface temperature to heat up more quickly.
The research team predicted the supercontinent environment through computer modeling and found that volcanic activity increased, carbon dioxide levels increased by about twice the current level, and solar energy increased by 2.5%. Moreover, the researchers explain that since humanity currently emits more than 40 billion tons
When all of these conditions are combined, the global temperature rises to 40 to 70 degrees Celsius, making it an inhospitable environment for mammals. Professor Farnsworth explained: “Mammals may survive in some areas around the North and South, but the dominant species on Earth could be cold-blooded reptiles that can withstand the heat.”
