What happens to those who dare to inject truth and common sense into the climate conversation

In one atmospheric physicist's case, you pay your own way home from the conference:

 American atmospheric physicist Murry Salby, has produced a serious analysis that undermines key assumptions underpinning the AGW worldview. His work and its reception illustrate just how unsettled climate science remains—and how determined AGW proponents are to enforce consensus on one of the great questions of our age.

In April 2013, concluding a European tour to present his research, Salby arrived at Charles de Gaulle Airport in Paris for a flight back to Australia, where he was a professor of climate science at Macquarie University. He discovered, to his dismay, that the university had canceled the return leg of his nonrefundable ticket. With Salby stranded, Macquarie then undertook misconduct proceedings against him that swiftly culminated in his dismissal. The university claimed that it did not sack Salby for his climate views but rather because he failed to “fulfill his academic obligations, including the obligation to teach” and because he violated “University policies in relation to travel and use of University resources.”

Salby and his supporters find it hard to believe the school’s claims. Salby’s detractors point to reports of his investigation by the National Science Foundation (NSF) for alleged ethical improprieties, claims surrounding which surfaced on an anti-climate-skeptic blog, along with court papers relating to his divorce. Salby has indeed been embroiled in conflicts with the NSF—the organization debarred him from receiving research grants for three years, even though, teaching in Australia, he wasn’t eligible, anyway—and with the University of Colorado, where he taught previously and was involved in a decade-long dispute with another academic. At one point, the NSF investigated the disappearance of $100,000 in Salby’s research funds, which, in the wake of the investigation, was returned to Salby’s group. However, all these matters have involved bureaucratic rights and wrongs. They have no bearing on his science . . . 

Freedom-Haters are relentless, which is why we must be as well.
