I don't see how you can make the claim that the "climate change case actually got better". Are you familiar with the busting of the hockey stick, for example? A lot of AGW models are utterly dependent on that piece of fiction. Yet despite it being revealed to be a fabrication based on a tiny subset of cherry picked data, nobody in the AGW community seems to care, nor have they spent the time to reformulate their models that were dependent on that data.
