It's like they are completely ignorant of the fact that the geologic record is littered with examples of warming and cooling trends that are totally unrelated to CO2 or orbital forcing. Which is why they will act all surprised when the planet experiences a cooling trend that completely disproves their beliefs. Of course given the fact that the planet experiences more frequent and more severe climate fluctuations because of the planet's land mass configuration and proximity to thresholds to extensive continental glaciation, they really shouldn't be surprised at all.
They ignore those facts because they prove beyond doubt that their claims are fraudulent.
