" How did they get ice to melt, the tropopause to rise, sea level to rise, water vapor to increase...all without a temperature increase?" 

They used a giant blowtorch that they borrowed from the aliens in Area 51 to melt part of the ice wall at the edge of the ocean. They were trying to get through, but the Illuminati saw what they were doing tried to kill them by warming the atmosphere around them with a doomsday laser. The scientists just jumped into the hole they made in the ice to escape the heat, so this is still going on. Global warming is caused by this doomsday laser and the talk of pollution and carbon are just a cover up by the Illuminati. Once they finish the job and kill the scientists, they'll turn off the laser and the ice wall will immediately cool the earth back down to where it should be.
