IT'S COLD UP THERE : CLIMATE CRISIS FACESEXISTENTIAL THREAT FROM POLAR CONTINENTAL DRIFT

In 2014 Kerri Smith told  Scientific American that in 50 million to 200 million years' time, all of Earth's current continents will be pushed together into a single landmass around the North Pole. 

That is the conclusion of an effort detailed in  Nature  to model the slow movements of the continents over the next tens of millions of years. 

CAN CLIMATE ACTIVISTS STOP THE DRIFT BY GLUING
  THEMSELVES ACROSS THE SAN ANDREAS FAULT?

A supercontinent last formed 300 million years ago, when all the land masses grouped together on the equator as Pangaea, centered about where West Africa is now. After looking at the geology of mountain ranges around the world, geologists had assumed that the next supercontinent would form either in the same place as Pangaea, closing the Atlantic Ocean like an accordion, or on the other side of the world, in the middle of the current Pacific Ocean.

But Ross Mitchell, a geologist at Yale University in New Haven, Conn., and his colleagues have a new idea. They analyzed the magnetism of ancient rocks to work out their locations on the globe over time, and measured how the material under Earth's crust, the mantle, moves the continents that float on its surface.

They found that instead of staying near the equator, the next supercontinent--dubbed Amasia--should form 90 degrees away from Pangaea, over the Arctic.

THE BEAUTY OF MITCHELL'S HYPOTHESIS IS THAT
