The International Geochronological Commission identified the last 4200 years of the development of the Earth in a separate period of history. According to the BBC, scientists have called this megahala era, whose countdown begins with a mega drought that has destroyed several civilizations.
Geologists have divided the Earth's 4.6 billion years of existence into several periods: destruction of continents, global climate change, the emergence or extinction of 39, animal and plant species. Now, humanity lives in the era of the Galocene, which began 11700 years ago – with the end of the last ice age. However, Halocene can also be divided into several periods.
Thus, the period that began 4200 years ago and continues to be called Megalachian era. In addition, on the geochronological scale will also appear the North African period, which began 8300 years ago and lasted until the beginning of the Megalakhae era, it is marked by the period of global cooling.

However, some representatives of the scientific community are worried about such a decision and are not convinced that climate change, taken as a separator of the three new periods, actually has a global impact on the development of the planet. 19659005] Read also: Geologists have discovered the oldest source of oxygen on Earth
