The British Guardian reports that a new study in the journal Nature Geoscience for the first time simulates the consequences of extreme climate due to land mass growth, arguing that the formation of a supercontinent would lead to extreme climate change.high temperatureSolar radiation and food growththe supply chainThe collapse, which would trigger a mass extinction that would wipe out all humans and extant mammals within 250 million years.

The research team used supercomputers to simulate the formation process of supercontinents and proposed that due to the continuous drift of the Earth’s land mass, the world’s continents gradually moved closer and merged, ultimately forming Pangea. Ultima) may have evolved over 250 million years. ,

Volcanic activity during the formation of the supercontinent will become more frequent and violent, causing thermal stress, and carbon dioxide emissions into the atmosphere will double from current levels. The aging Sun will emit more radiation, and the desert troposphere will gradually expand into the interior.

Once we enter the Ultimate Pangea period, extremely high temperatures will become more intense, humidity in coastal areas will be higher than it is now, and vast inland deserts may suffer extreme drought. By then, global temperatures will have increased by 15 degrees Celsius compared to pre-industrial times, returning the world to the Permian-Triassic era 260 million years ago, which caused mass extinction of life and the disappearance of more than 90% of species. Gone.

Many life forms cannot tolerate prolonged exposure to temperatures above 40 °C.

In addition to direct impacts, higher temperatures will make it difficult to maintain vegetable crops and indirectly harm the food supply chain. Studies have noted that most plants will experience stress in environments above 40 °C, and will be completely destroyed if exposed to an environment below 60 °C for a long time.
