A climate change advocate, believed to be a Greenpeace activist and Guardian contributor, has called for the beheading of so-called “climate change deniers”, arguing the world would be a better place without them. The comments are merely the latest in a long history of warmists advocating the killing of people who question global warming dogma.

On January 21st, in it’s ‘Climate Consensus – the 97%’ section, the Guardian published an article entitled “Matt Ridley wants to gamble the Earth’s future because he won’t learn from the past”, which was illustrated with a fake, but nonetheless rather gruesome image of a severed head.

The article drew hundreds of comments, including one from ‘Bluecloud’ on the day the article was posted, reading “Should that not be Ridley’s severed head in the photo?”

Further down he added “We would actually solve a great deal of the world’s problems by chopping off everyone’s heads.

“Why are you deniers so touchy? Mere calls for a beheading evolve [sic] such a strong response in you people.

“Ask yourself a simple question: Would the world be a better place without Matt Ridley?

“Need I answer that question?”

The comment has since been removed by moderators, allowing ‘Bluecloud’ to attempt to deny that he had called for violence. On Sunday morning he commented “Oh dear, it didn’t take much for the denial industry to start claiming environmentalists are out to chop off people’s heads.

“It’s clear that when they have no argument to make, they stoop to misquoting deleted posts”

Others also tried to deflect blame, with commentor ‘ianhassall’ writing “Bluecloud’s moderated comment is causing quite a stir, isn’t it.

“If warmists can’t get their point across with the settled science I’ve got no doubt they’d resort to the sort of violence he’s suggesting.”

To which Bluecloud replied: “And what violence would that be? Making false claims is easy in the absence of evidence.”

Unfortunately for Bluecloud, the evidence is easy to come by on Twitter. Climateologist Richard Tol has tweeted a screenshot of his original comment in full:

Furthermore, the Bishop Hill blog is reporting that others commenting on the Guardian article revealed Bluecloud to be Gary Evans, a Greenpeace funded “Sustainability Consultant”, according to his Linked In profile, who has written for the Guardian in the past.

The comment fingering Evans was apparently deleted by the Guardian moderators far in advance of Evan’s comment being deleted.

Bluecloud’s comment comes a week after a Professor Emeritus of Physics at Princeton University called climate change activism a “jihad against atmospheric carbon” in a new paper for the Global Policy Warming Foundation.

However, this is not the first time that global warming advocates have threatened violence against those who question the theory of anthropogenic global warming. In 2010 Greenpeace’s Gene Hasmi wrote: “Pressuring politicians on climate change is not working. We saw that in Copenhagen. Three months later, we also know why. Which is why the global climate movement now must do course-correction. We need to shift targets and go after the real termites that hollowed out and imploded Copenhagen.

“Emerging battle-bruised from the disaster zone of Copenhagen, but ever-hopeful, a rider on horseback brought news of darkness and light: “The politicians have failed. Now it’s up to us. We must break the law to make the laws we need: laws that are supposed to protect society, and protect our future. Until our laws do that, screw being climate lobbyists. Screw being climate activists. It’s not working. We need an army of climate outlaws.”

“The proper channels have failed. It’s time for mass civil disobedience to cut off the financial oxygen from denial and skepticism.

“If you’re one of those who have spent their lives undermining progressive climate legislation, bankrolling junk science, fueling spurious debates around false solutions, and cattle-prodding democratically-elected governments into submission, then hear this:

“We know who you are. We know where you live. We know where you work.

“And we be many, but you be few.”

2010 also saw the release of the 10:10 Campaign’s supposedly comedic ‘No Pressure’ video, penned by Richard Curtis, in which children and office workers who don’t want to do their bit to prevent climate change are blown up by hitting a big red button.
