Another dissenter of AGW: Murry Salby
Professor Murry Salby advances his analysis of climate change and the role of CO2. His conclusion: increase in CO2 is not a cause of global warming because CO2 tracks temperature change, not vice versa; modern high levels of CO2 are not at all unusual or historically unprecedented; human emission of CO2 and methane is not a significant factor in climate change; models currently used for long-time climate prediction are completely inadequate and should not be trusted.

This somewhat monotonous and somber lecture was delivered shortly before Salby was dismissed from his university position. The university canceled his return ticket and held dismissal hearings in his absence.

The Wikipedia page on Salby never mentions the possibility that he could have been dismissed because of his views on climate. The Wikipedia page instead discusses at length the various allegations of misconduct made against Salby at the last two universities where he held academic positions. Salby's views on climate, or their reception by the academic community, are not discussed in any detail in the Wikipedia page.

The science is far from settled. Many scientists dissent - especially scientists who have no political stake in the matter:
