skeptical inquiry

Cold Spots (a.k.a. Chills): An environmental anomaly marked by a sudden and focused drop in temperature is commonly referred to as a "cold spot," but warm spots are also recorded. Paranormal enthusiasts theorize that "spirits" draw energy from the environment in order to manifest themselves, and that a drop in temperature is the "footprint" of a spirit trying to manifest. Consequently, investigators use thermocouples (thermometers) and thermal images to track the movement and, in some cases, the shape of these thermal anomalies in hopes that they are monitoring an entity.
