This weekend, when you go see the movie, keep in mind 2 things:
1. If all the ice in the polar ice caps melted, and all the water in the atmosphere fell to the ground as rain, and all the glaciers and mountaintop snow melted, and it all went into the ocean...the level of the ocean would rise less than 150 feet.
2. In order to crash an aircraft carrier into the White House using a tidal wave, you would need to either drive the tidal wave in from the Atlantic, which is over 165 miles away, or drive a tidal wave up and over the Delaware Peninsula, an overland trip of nearly 35 miles. For this to happen, the earthquake would shake apart the planet.
For reference, the second strongest earthquake recorded in human history happened in the Indian Ocean in 2005, and sent a wall of water 33 feet high as far inland as 1.24 miles. So basically we would need an earthquake around 10.3 on the Richter scale to achieve ten times the power of the Indian Ocean quake. The strongest earthquake ever recorded was a 9.5 on the Richter scale.
And that is just the beginning. By the end of the movie, tsunamis are rushing up the sides of the Himalayan mountains. The earthquakes required to do this would imply the Earth is splitting into pieces, and the cracks in the crust would be so large that all water on Earth would evaporate in the heat of the escaping molten core material.
But enjoy the movie.
