At the end of the Paleozoic era, one of the largest extinctions in the history of the Earth happened - the Permian. Scientists are trying
Among the main versions, why approximately 252 millionyears ago there was such a mass extinction, called global climate change, namely warming. Previously, scientists suggested that the Permian extinction of species lasted 40 thousand years, and this is very fast in history. It is believed that during this time the average temperature on the planet rose by 10 degrees, and the pH of the water in the ocean fell sharply.
The authors of the new scientific article say that suchThe models contradict the data of geochemistry and paleontology. They point out that environmental changes began to occur long before the extinction event. The analysis showed that the temperature of the water in which the ancient crustaceans swam began to increase 300 thousand years before extinction. During this time, the average temperature rose by 12 degrees.
