Two children refuse to comply with the fascist agenda of global warming austerity and are subsequently detonated by their teacher, covering their classmates in a sea of blood and body parts.

I predicted this morning that No Pressure – Richard Curtis’s spectacularly ill-judged eco-propaganda movie for the 10:10 campaign – would prove a disastrous own goal for the green movement.

But what I could never have imagined was how quickly public disgust – even among greenies – would reach such a pitch that the campaigners would be compelled to withdraw it from the internet.

That, at any rate, is what they keep trying to do – cancelling it whenever it appears on You Tube, pulling it from their campaign website and so on.

Unfortunately their efforts are being frustrated by people on the sceptical side of the climate debate, who keep peskily insisting on reposting the video where everyone can view it. And rightly so. With No Pressure, the environmental movement has revealed the snarling, wicked, homicidal misanthropy beneath its cloak of gentle, bunny-hugging righteousness.
