The purpose of climate change denial lobbyists is to convince the public that lawmakers shouldn't take any action to address climate change. This is to protect the profits of certain groups, especially the fossil fuel industry which supplies most of the funding for these lobbyists. They have been very successful at this in the past, but there have been signs lately that indicate they are now losing the battle for the public's mind. Take a look at how irrelevant one of these lobbyists, Tom Harris, has become. Now, the lobbyists themselves have been gracious enough to show us they no longer matter.
The Climate Depot has long been one of the most notorious of these denier lobbyists. Marc Morano of that organization has a long track record of making false statements and false arguments. He is also the communications director of the Committee for a Constructive Tomorrow (CFACT), yet another fossil fuel supported organization. He has even gone as far as providing the personal contact information for climate scientists and encouraging people to send them threatening and harassing communications. In the movie Merchants of Doubt he not only admits this but calls it one of his proudest accomplishments and laughs. Now this shining example of humanity has made his own film - Climate Hustle. The purpose of this film is to supposedly show how climate change is all a big hoax and nothing to worry about.
The plan was to premier their new film in Paris during the COP21 conference with the hope they would make a big splash. Oops! They succeeded in making some news, but not the way they were hoping. The premier was a massive dud and they couldn't fill the theater, even with free tickets.
So, what we have is the deniers are spending a huge amount of fossil fuel money on a project that even the deniers won't watch for free. Well, they are right about one thing. Fossil fuel money does create jobs. If nothing else, I'm sure the people who worked on this project appreciate the money they were paid.
But, you have to wonder how much longer this boondoggle will continue when no one is listening to them anymore.
