In this episode, Earth is suffering from a gigantic heat wave, due to Global Warming. Nice to know that it didn't kill the planet by the year 3000. Anyway, the Planet Express crew are hired to go to Halley's Comet and retrieve a giant ice block. This is how the planet has been combating Global Warming. They would get a giant cup, attached to a giant drill, the would be used like an ice dispenser. Then they would drop the ice cube into the ocean. But every time, the ice block had to be bigger. When the crew went to do this task, there was no ice on Halley's Comet. It had been completely sucked dry. Eventually, Al Gore holds a Global Warming convention. When there, Professor Farnsworth reluctantly tells the crowd that he sped up the process from the pollution from his robot emissions. Later, President Nixon's Head invites all of the worlds robots to the Galapagoes Islands for a big party. There, he planned to kill all of the robots. Instead, Bender and his robot pals used their emission gases to push them away from the Sun. I'm pretty sure that's one happened. They farted to do something like that.
Overall, I give this episode a 10 out of 10.
