The terms "climate change" and "global warming" are used like the term "UFO", to shift the ground and misrepresent one position as another.
Flying saucer enthusiasts use the term UFO to mean extraterrestrial vehicles, even though "unidentified flying objects" are by definition not identified as having any particular origin. Then they point to records by government sources referring to UFOs as proof that flying saucers exist, and that governments are deliberately covering them up. Governmental reports of course only refer to sightings of something which could not be identified.
The same shift constantly occurs in the use of the "global warming" terms (now more than one term, soon no doubt to be further varied). Enthusiasts incorporate the "human caused" aspect into the term in their conclusion of the argument, but only argue on the temperature rise in establishing the argument. They don't even realise they are being dishonest, as they move seamlessly from one point to the other without understanding that they are distinct and that the link has not been established, at least for those persons they deride as "deniers".
