Novopangaea

Novopangaea or Novopangea (Greco-Latin for "New Pangaea") is a possible future supercontinent postulated by Roy Livermore in the late 1990s. It assumes closure of the Pacific,[1] docking of Australia with East Asia and North America, and northward motion of Antarctica.
Alternative scenarios
Research by Masaki Yoshida and Madhava Santosh in August 2011 suggests that due to the presence of relatively hot large low-shear-velocity provinces below Africa and the Pacific preventing convergent plate tectonics, South America might not be able to cross the Pacific as suggested by the Novopangaea model, rather staying close to its current position relative to North America, and Antarctica may not be able to leave the South Pole as suggested. Therefore, they suggest that while Eurasia, Africa, Australia, and North America may merge as suggested, South America and Antarctica will remain separate from the resultant supercontinent by an only partially closed Pacific Ocean.[4][5]
