The Earth is now in a new geological age. The International Union of Geological Sciences said that this age, nicknamed the Meghalayan, began 4,250 years ago when drought hit the planet.

Holocene Epoch

We are currently in the Holocene epoch, which reflects everything that happened 11,700 years ago, since after the last ice age. The epoch itself, however, is subdivided into different periods called stages or ages, and we are now its youngest stage.

In a statement released July 13, the UISG said that this age, the Meghalayan, is one of three The other two are the Greenlanders, which took place 11,700 years ago at 8,326 years after the last Ice Age, and the Nordgrippian, which occurred 8,326 years ago at 4,250 years ago, when the Earth abruptly began. the Holocene is now defined by three stages: the Holocene Greenland lower stage, the Middle Holocene Northgrippian stage, and the upper Holocene Meghalayan stage, "the Holocene is now defined by three stages : The International Commission on IUGS Stratigraphy (ICS) said in a statement. "The lower limit of each 2 is set to a carbon isotope excursion that defines the respective climatic event. "

The Meghalayan era

Meghalayan began with a global drought that had devastating impacts on ancient civilizations in China, Greece, Mesopotamia, Syria, Palestine, the Valley of Africa. Indus, the Yangtze River Valley and Japan The mega-drought, which lasted 200 years, was probably the result of changes in ocean and atmospheric circulation.

The name "Meghalayan" is a blink of an eye. 39; eye to a sample llon of rock that geologists have analyzed since Meghalaya in India. The analysis of stalagmite growth on the soil of Mawmluh Cave revealed that each layer of stalagmites exhibited different levels of oxygen isotopes

"The isotopic shift reflects a decrease in 20 to 30% of monsoon rainfall ". from Wales, United Kingdom. "The two most important changes occur around 4,300 and about 4,100 years before the present, so the midpoint between the two would be 4,200 years before the present, and it's the age that we attribute to the [Meghalayan golden spike]

What makes the Meghalayan Age unique?

IUGS Secretary General Stanley Finney said that the Meghalayan is unique to others geological time scale intervals because its beginning marks a major cultural event associated with global climate events It comes at a time when societies have sought to recover from climate change
