Using paradigm shifts to discredit current climate science, both disavowing the current computer shift and suggesting a new (old) shift.

Precisely. Though the comments on the video were better than expected.

He takes a long time to establish this idea of "plausible fables" in order to make it seem as though his ideas are on the cutting edge of a future paradigm shift. I find it interesting how many cranks do this. First they make the argument that people used to believe things that weren't true, and the obvious next step is that we currently believe things that aren't true (almost certainly correct in many areas) and then they apply it to their own pet idea, whether it is global warming, HIV denial or whatever... but they miss a step in the process where all these previous "paradigms " were overturned due to a superior explanation, not just because people were poking holes in what was up till then the best explanation people had come up with. And certainly not just because some crank insisted that it was about time for a paradigm shift!

Also, astrology? Enough said.
