Earlier this month, the Los Angeles Times officially confirmed the paper is no longer running letters to the editor that deny the scientific conclusion that climate change is a reality and is caused mainly by human activities.
Prior to this, the magazine Popular Science went even further and completely turned off the comments section for its entire website, stating quite eloquently that, “Everything, from evolution to the origins of climate change, is mistakenly up for grabs again. Scientific certainty is just another thing for two people to 'debate' on television. And because comments sections tend to be a grotesque reflection of the media culture surrounding them, the cynical work of undermining bedrock scientific doctrine is now being done beneath our own stories, within a website devoted to championing science.”
The L.A. Times editor stated the paper's reasoning as, “Letters that have an untrue basis (for example, ones that say there's no sign humans have caused climate change) do not get printed.”
The Sydney Morning Herald has subsequently announced it also won't allow climate deniers to “misrepresent facts” on climate science in letters - an especially powerful case given the terrifying fires ravaging Australia against a backdrop of continuing broken heat records.
As the former Editor of DeSmogBlog, most of the climate deniers and self-proclaimed skeptics I have encountered over the years have been paid by Exxon, the Koch brothers or other such industry interests, making a good living as fake experts for hire. They are manipulators of the truth.
Of course, not all are paid mouthpieces, and some of them just simply believe that climate change isn't happening or it isn't caused by burning fossil fuels.
To those people not being paid by industry to sell doubt, to those who in their heart-of-hearts actually question the realities of climate change, I would say they have every right to submit their opinions as letters to a newspaper.
But just like the guy who sends in a letter each week to the paper insisting he was abducted by aliens, or that 9-11 was a hoax, it is up to the paper to decide what to print and what to throw in the waste basket.
