The study linked below used scientific analysis to examine the fallacies in arguments denying human-caused climate change.

It found that the arguments climate change are often self-contradictory and that dissent is used by stakeholders to undermine the authority of science in order to postpone inconvenient political action: 

"Climate science denial is therefore perhaps best understood as a rational activity that replaces a coherent body of science with an incoherent and conspiracist body of pseudo-science for political reasons and with considerable political coherence and effectiveness."

In other words, whereas the deniers complain loudly about a conspiracy against them, the evidence points to a dcoordinated conspiracy to ward off political action addressing global warning because they think it will be to expensive and hurt their short-term profits.
