Plot The new, state-of-the-art nuclear submarine, Seaview, is on diving trials in the Arctic Ocean. Seaview is designed and built by scientist and engineering genius Admiral Harriman Nelson (USN-Ret). Captain Lee Crane is the submarine's Commanding Officer. One of the on-board observers is Dr. Susan Hiller, studying crew-related stress. The mission includes being out of radio contact for 96 hours while under the Arctic ice cap. The polar ice suddenly begins to crack and melt, with boulder-size pieces sinking into the ocean around the submerged submarine (no explanation is given as to why the ice sinks). Surfacing, they discover the sky is on fire. After rescuing scientist Miguel Alvarez and his dog at Ice Floe Delta, Seaview receives a radio message from Mission Director Inspector Bergan at the Bureau of Marine Exploration. He reports that a meteor shower has pierced the Van Allen radiation belt, causing it to catch on fire, resulting in a deadly increase in the global temperature. Nelson's on-board friend and scientist, retired Commodore Lucius Emery, concurs it is possible. The President summons Admiral Nelson to a UN Emergency Scientific meeting. Nelson and Commodore Emery have devised a plan to end the catastrophe. Seaview arrives in New York Harbor two days later. Nelson informs the UN that, according to their calculations, if the increasing temperature is not stopped, it will become irreversible and the Earth will die in about three weeks. The Admiral and the Commander propose extinguishing the fire by launching a nuclear missile at the burning belt from the Mariana Islands. A nuclear explosion should overwhelm and extinguish the flames, "amputating" the belt from the Earth. Seaview has the capability of firing the missile. The chief scientist and head delegate, Vienna's Emilio Zucco rejects the Admiral's plan as too risky. He believes the composition of the belt's gasses will cause the fire to soon burn itself out when reaching 173 degrees. Nelson disagrees with Zucco's theory, claiming that his estimated burn-out point is
