Corrected entry: After it comes to light that Laura's leg is in a bad state, Sam and friends decide to risk going outside to the ship to find some first aid. A First Aid cabinet is visible during the scene where the library vending machine is smashed. Fair enough Sam and friends may not be aware of this being there, but there are two members of library staff who should know about this. No attempt to bring this to Sam's attention is made while he is creating his snow shoes.
Corrected entry: They need to get on board the ship for medical supplies, but there is a medical supply box in the cafeteria when they break open the vending machines.
Corrected entry: There's a scene when the storm starts freezing the buildings in New York and windows break from the extreme freezing temperature. Later in the end of the film, when the helicopters come to look for survivors, some land on the buildings with all the windows intact.
Corrected entry: When the ship sails into New York city, it is stopped in a matter of feet when the wreck of the city bus is trapped underneath the bulb stern. A ship with that size and speed would have enough momentum to move the city bus much further. However, in that case it wouldn't conveniently stop outside the library.
Corrected entry: A tornado is shown tearing apart a skyscraper in downtown Los Angeles. Most modern day skyscrapers can actually withstand even the most powerful tornadoes.
Corrected entry: Even though many buildings and even the American flag freeze completely solid in some scenes, this fails to happen to any of the main characters, despite the fact that some sleep outside in tents during a snowstorm without a jacket or hat.
Corrected entry: While working in Antarctica, Dennis Quaid and the other scientists have nothing to cover their faces with. It is so cold in Antarctica that if this were to happen, their faces would literally freeze to death. Real scientists will wear two face coverings and goggles to protect them from the wind and cold.
Corrected entry: There are over thirty public libraries in Manhattan. How does Jack know which one to go to? Before his son went under water, he only says he is in the public library.
Corrected entry: New York is flooded with a tidal wave, yet just several hundred miles down the coast, Washington DC, which is not much above sea level, is not flooded at all, as the president is still in his office just before the major snow storm. A major tidal change of that size would equalize: water would flow to lower levels near DC.
Corrected entry: If New York City has lost power, the cell phone towers are inoperable. Therefore, cell phones will not work. This very problem happens all over the country when there is a power failure. There is not always another tower close enough to pick up your signal.
Corrected entry: When the helicopters are flying over Scotland and through the eye of the storm, the temperature is cold enough to freeze fuel in the pipes and tanks. Yet the pilot takes a good five seconds to open the window, and then freezes. Logically, anything cold enough to freeze fuel should not have given him that long. Fuel has a much lower freezing point than the human body. Plus, fuel pipes, even though metal, are usually in an area hotter than the cabin, since the engines are running there, generating heat. Even with the added padding of a coat, a body just could NOT have taken longer than fuel to freeze. The pilot should not even have had time to reach for the window before freezing, let alone to open it and then wait a good five seconds to do so.
Corrected entry: When we see the closeup of Laura's cut leg, the skin around it is nice and smooth. However, any girl can tell you that after spending several days camped out in the library, they would be stubbly at the very least. They can't expect us to believe that she's still been shaving her legs throughout this ordeal.
