Climate and paradigm-shifts

Peter Foster brings up a useful allusion to Kuhn in his contribution to the National Post's "Junk Science Week":

In his classic book The Structure of Scientific Revolutions, Thomas Kuhn noted that scientific groups adopted, and committed to, "paradigms," which then became fundamentally unquestionable. That stance was hardened further when moral values, such as being "socially useful," were involved.

The IPCC came with its moralistic paradigms pre-installed.
