When the history of the greatest pseudoscience fraud in history -aka “Climate Change” – comes to be written, no media organisation, not even the Guardian or the New York Times, will deserve greater censure than the steaming cess pit of ecofascist bias that is the BBC. That’s because, of all the numerous MSM outlets which have been acting as the green movement’s useful idiots, the BBC is the only one which is taxpayer funded and which is required by its charter to adopt an ideologically neutral position.
The BBC has held a high-level seminar with some of the best scientific experts, and has come to the view that the weight of evidence no longer justifies equal space being given to the opponents of the consensus. [emphasis added]
