When Dr. Jordan Fisher is in the helicopter reporting water temperature changes at Lake Mead, he is giving figures over a hundred (indicating degrees Fahrenheit). Scientists, however, generally use the Celsius scale in which water boils at 100 degrees and cannot get hotter and remain liquid except under pressure. Furthermore, the lake surface is shown as already boiling, which, on the Fahrenheit scale, occurs at 212 degrees, not at the 95 - 107 degrees reported in the dialogue. It's wrong in either scale.
