Mayan civilization may have been destroyed by drought

On February 23, scientists said the collapse of the Mayan civilization seems to have occurred due to the relatively mild droughts, similar to the dry weather control over the past few years because of gas changes. post.

Previously, scholars believed that a serious drought could have killed the ancient Maya culture that was famous for mastering language, mathematics and astronomy.

However, researchers at the Yucatan Science Research Center in Mexico and the University of Southampton in the UK have shown that their analysis shows that drought only reduces 25-40% of annual rainfall. But less rain also means that the water sources in the ponds and lakes quickly evaporate.

Co-author Eelco Rohling of the University of Southampton said: "The data shows that the main cause is the decline in tropical storm activity in the summer ."

This is the first study to accurately assess how much rainfall has decreased since 800-950 AD when the Mayan civilization began to decline.

Scientists calculated using data models based on information about changes in precipitation and the situation of lake water reduction in the area that used to happen. The results showed that a very small drought could cause severe water shortages in an area without rivers and there were no other sources of water other than rainwater like Yucatan.

Rohling said: "Summer is the main season for growing and supplementing the Mayan clean water, the lowlands Yucatan has no rivers. Social disturbances and people's abandonment of cities seem to be The consequences of serious water shortage, especially when the drought seems to have been going on for years ".

International experts also forecast similar deadlines in the upcoming Yucatan region because of climate change.

The main researcher, Martin Medina-Elizalde of Mexico's Yucatan Scientific Research Center, said that while modern society is better equipped to deal with drought, there is still a great risk.

Mr. Elizalde said: "Our studies show that there is only a small decrease in precipitation between different times, when the Mayan civilization is prosperous and when it collapses, perhaps from 800 -950 AD The decline of only about 25-40% of the annual rainfall falls, but it has also caused serious problems and long-lasting consequences, these problems not only appear on sale. Yucatan island but also occurs in many areas with similar weather conditions, where water evaporates strongly ".
