Jacobs has interviewed more than a thousand people who claim to have been abducted, using hypnotic regression that apparently allows them to recall their unearthly encounters with aliens. (Mind you, this too is controversial, and Jacobs himself admits that people should be skeptical of these recollections.)
Chi takes the claims at face value, and links the growing number of abductees cataloged by Jacobs to the increase in atmospheric greenhouse gases. He doesn’t imply a cause and effect: The abduction experiment is not responsible for global warming. Rather, it’s a reaction to it. The extraterrestrials are producing hybrids that can better withstand the rigors of a toastier planet. By producing a new model of Homo sapiens, this project would eliminate the need for difficult climate accords or elaborate geoengineering projects. It would also help the aliens themselves — who are said to be living among us — by preserving the part of their DNA that’s carried by the temperature-tolerant hybrids.
