Glaciers melting in the North Pole cause redirected oceanic currents that lead to extreme flooding in North America along the oceans and Great Lakes. The rapid erosion loosens faults, causing earthquakes and extreme tsunamis, as well as more flooding along the Mississippi and Colorado Rivers. America is now sinking, and scientists must work across the U.S. to carefully form sinkholes to balance out the water and return freezing temperatures to the North Pole.
