The two sides of the climate change or global warming debate are:

1. Man-made Global warming theory (MMGWT) Proponents (MPs)
2. MMGWT Denialists (MDs)

Each side is backed up by a “central dogma”. The central dogma is a claim that if debunked discredits the entire movement.

The central dogma of MPs is “that there are greenhouse gases that act to retain heat, which in turn can change climate over time”.

The central dogma of MDs is “that man cannot change climate, no matter what he does”.

Ironically, the MPs’ “central dogma” is NOT a dogma at all, since it can be tested via experiment on actual samples of gases said to be “greenhouse”, which can be peer reviewed and is reproducible by others.

By contrast, the MDs’ central dogma really is a dogma, since there is no way to debunk it. No matter what records you present to show an increase of greenhouse gases like CO2 since the 1950s, no matter what temperature records over the past century or so you present, no matter what records of solar activity you present, MDs will always come up with excuses for rejecting the case of the MPs, including arguing that the records must have been faked. So the position of the MDs is unscientific because it is non-falsifiable.

Well, you cannot fake experimental data. If the “central dogma” of the MPs were indeed false, it would have been debunked many decades ago. Instead, it is so well supported that this “central dogma” is considered as much a fact as anything else in science could be.

So MDs avoid the MPs’ “central dogma” and instead constantly argue around it. They confuse uncertainty about global warming models and projections with reasons to deny them completely. They also note the many natural causes of climate change as if that alone supports their central dogma. Both of these are logical fallacies called  non-sequiturs. They harp about the few remaining scientists who are MDs as if their credentials alone make them credible. But they don’t, because even scientists with PhDs and tenures at universities can be profoundly wrong, especially if they have ideological or financial reasons to corrupt their science.

MPs do not have to attack the central dogma of MDs because, as I showed above, it is unscientific. They just have to point out that it really is a dogma, nothing more.
