While the film is a classic action movie featuring hugely exaggerated events
(total shutdown takes place over a few days rather than decades, tidal waves
in New York flood the city and then turn into a massive ice block within
hours), it does present some genuine scientific information about ocean
circulation, ice core sampling and past climate shifts. The film has been
broadly welcomed by scientists as a way to raise awareness about the
importance of climate change issues.
"Two Days Before the Day After Tomorrow" also parodies the film The Day After Tomorrow, and general responses to global warming. For instance, Stan calls his father on the phone while the water level rises is a reference to a similar scene in The Day After Tomorrow where Sam calls his father while trying to outlast the fatal coldness.
