As the North Pole's ice cap begins to melt at an alarming rate, the Earth's climate rapidly deteriorates, leading to unprecedented natural disasters. Dr. Terry Rapson, a paleoclimatologist, and his colleagues have been tracking the unusual weather patterns, but their warnings fall on deaf ears. Meanwhile, in New York City, Jack Hall, a paleoclimatologist himself, is trying to reconcile with his estranged son, Sam, who has just started at a prestigious university. As the severe weather events intensify, Jack's attempts to connect with Sam are constantly interrupted by the chaos outside. As the day unfolds, catastrophic hurricanes and tornadoes wreak havoc across the globe, causing widespread destruction and loss of life. The National Weather Service, led by Dr. Lucy Woodley, is struggling to predict the next disaster as the climate continues to deteriorate at an exponential rate. In a desperate bid to save his son and thousands of others trapped in the city's central park, Jack Hall makes a perilous journey through the treacherous streets, facing unimaginable challenges along the way. As the temperature plummets and the ice age begins to set in, Jack must use his knowledge of paleoclimatology to outsmart nature and find a way to save those around him. As the clock ticks down, the world is thrown into chaos, with the very survival of humanity hanging in the balance. Will Jack be able to overcome the odds and save his son, or will the devastating consequences of global warming prove too great to overcome?
