Art Bell welcomes climate scientist Dr. Roy Spencer for a first-hour discussion on global warming, then opens the phone lines with a playful challenge: what would you do if you could become invisible? Broadcasting from Manila and filling in for George Noory, Art covers a recent earthquake he felt on the 19th floor of his building and addresses a Philippine newspaper that republished an infamous internet hoax letter bearing his name.

Dr. Spencer, principal research scientist at the University of Alabama in Huntsville and a NASA Medal recipient, presents the skeptic position on climate change. While agreeing that warming is real, he questions whether mankind is primarily responsible, pointing to natural cloud variability and ocean heat storage as underexplored factors. The conversation addresses the muzzling of government climate scientists, the limitations of the Kyoto Protocol, and why nuclear power may be the only realistic solution.

During open lines, callers share what they would do with invisibility, ranging from infiltrating Area 51 to visiting the Playboy Mansion. Several listeners describe experiences of making themselves mentally invisible to people standing just feet away. The regular caller J.C. phones in to declare Halloween a satanic ritual and pumpkins an invitation for demonic possession.
