The International Commission on Stratigraphy has put forward a proposal to change the system of geological and historical eras, taking into account the newly discovered data. Formally, we live in the era of the Anthropocene, when most of the events on the planet occur under the influence of man. But it does not and cannot have clear boundaries - instead, it is proposed to designate the current era as "Megalaya", which started 4200 years ago.
According to the classical scheme, the era of the Cenozoic is now on Earth, its last, Quaternary period. It is divided into the Pleistocene, when almost everything was covered with glaciers, and the Holocene - the ice left, wild people began to master agriculture, construction, crafts, etc. But if from the standpoint of global geology the Holocene is almost the same throughout its entire length, then for humanity there have been many real fateful events that clearly divided history into "before and after".
The main separator is unanimously called the Great Drought, which began in 2300 BC. and lasted for about 100 years. Ancient Egyptian civilization, the Kingdom of Liangzhu, the Akkadian Empire, the Indus Valley Civilization - all these proto-state formations fell into extreme decline. There are traces of a grand drought in stalagmites in India, which show the levels of monsoons. The emerging prosperity of people almost gave way to total extinction, but our ancestors adapted and survived. And now we call this new era the Meghalayan Age.
Alas, not everything is so simple. If earlier the boundaries between eras were determined by significant geological events, then Megalaya was started by both a natural and a cultural-historical incident. Given that Megalaya entirely lies within the boundaries of the artificial Anthropocene, which is within the natural Holocene. What criterion, natural or man-made phenomenon, should now dominate in defining the boundaries of eras? For example, if tomorrow there is a Third World War with an exchange of nuclear strikes and the fate of mankind again takes a sharp turn due to a radical change in habitat, will this be the beginning of a new era? Scientists' disputes continue.
