Research by Elma from Rice Earth University has reinforced evidence from previous research that the drought is behind the Mayan disappearance.
After studying the “blue hole” and surrounding waters, scientists found changes in the rates of aluminum and titanium during the 9th and 10th centuries, the same period that saw the decline of the Mayan civilization in the Yuktan Peninsula, and the decline of the latter material means a decrease in rainfall.
The rate of substances decreased further between 800 and 1000 AD. By 900, most cities had been abandoned by civilization, which had spread to countries now Guatemala, El Salvador, Honduras and southern Mexico.
The Maya civilization has a scientific and astnomical legacy, especially with regard to the Gregorian calendar, which was interrupted on December 21, 2012, leading many to believe that it was the date of the end of the world.
The theory of drought and drought behind the extinction of the Mayans is not new, as scientific research conducted in 2012 concluded that the region suffered from drought in the other half of the first millennium AD.
