The official history of Earth has a new chapter - and we are in it.

Geologists have classified the last 4,200 years as being a distinct age in
the story of our planet.

They are calling it the Meghalayan Age, the onset of which was marked by a
mega-drought that crushed a number of civilisations worldwide.

The International Chronostratigraphic Chart, the famous diagram depicting
the timeline for Earth's history (seen on many classroom walls) will be
updated.
