As climatologist named Jack Hall was in Antartica, he discovers that a huge ice sheet has been sheared off. But what he did not know is that this event would trigger a massive climate shift that would effect the world population. Meanwhile, his son, Sam was with friends in New York to attend an event. There they discover that it has been raining non-stop for the past 3 weeks, and after a series of weather related disasters that occurred over the world. Everybody soon realizes that the world is going to enter a new ice age, as the rest of the world population tries to evacuate to the warm climates of the south. Jack makes a daring attempt to rescue his son and his friends who are stuck in New York, who have to survive not only a massive wave, but freezing cold temperatures that could possibly kill them.

A look at what the world would look like if the greenhouse effect and global warming continued. At the center of the story is a paleoclimatologist (a scientist who studies the ways weather patterns changed in the past), Professor Jack Hall, who tries to save the world from the effects of global warming while also trying to get to his son, Sam, who was in New York City as part of a scholastic competition, when the city was overwhelmed by the chilling beginnings of the new Ice Age. In addition to all of the other challenges Dr. Hall faces, he's also going against the flow as humanity races south to warmer climes, and he's nearly the only one going north.

 

When global warming causes world wide disasters and leads to an ice age, a climatologist named Jack Hall tries to rescue his son Sam who is trapped in New York. Jack must go from Washington D.C. to New York, but on the way some things happen. Can Jack rescue his son?

Professor Jack Hall, discovers that due to global warming, the polar ice caps are melting, which is lowering ocean temperatures. This triggers a massive climate shift which causes many natural disasters and eventually a new ice age. Too late everyone realizes this, and as they try to evacuate to the warmer south, for half of the northern USA, and Canada, it's already too cold to go outside. Meanwhile, Jack's son, Sam, is in Manhattan on a trip with some friends. Jack heads north to try and rescue his son, but the cold is a powerful adversary so he couldn’t help his son.
