This is wrong on so many levels. Fortunately, for those of us who are not fans of Fascism, such prosecution will not survive the First Amendment. For a scientific hypothesis to get politicized to such an extent as to try to muzzle the counter point, even if right, it is against everything a free society stands for and an end to free scientific inquiry.
Did you say the same thing when the tobacco industry was sued for lying about the harm of their products?
You can group the deniers into two camps.
1) fossil fuelled lobbyists paid to spread disinformation
2) anti-science types who soak up this disinformation
Once you start suing those who are paid to spread disinformation and who pay to spread disinformation then the anti-science types, like you, will either have to read the legit science or have to search for ever kookier, crazy wingnut types like Tim Ball (quoted on this site often) to find their 'research'. Then they can join the 9/11 truthers, anti-vaxxers, area 51 searchers and other wacko conspiracy types to their hearts content. What it means is that paid lobbyists won't risk being sued to spread disinformation on the MSM so you'll be stuck with wacko's like Tim Ball as your movement's spokesmen.
Scientists who have disputing theories about climate change will still be able to do their research and publish it, as they are now. People would be free to discuss and argue about the science. Nothing would change on that end, only on those who are being paid to spread disinformation.
From the original article:
Speaking at a press conference on March 29, New York Attorney General Eric Schneiderman said, “The bottom line is simple: Climate change is real.” He went on to say that if companies are committing fraud by “lying” about the dangers of climate change, they will “pursue them to the fullest extent of the law.”
These are the same people that went after Exxon after they were found to have done research that found that anthropogenic climate change is real then went and buried that research and started funding disinformation organizations like the Heartland Institute.
