Roughly every two years, someone is allowed on to the BBC Radio Today Programme to question climate change hysteria, for about two or three minutes. Previously it’s been Nigel Lawson, whose appearance was followed by howls of outrage from the climate mafia and a grovelling apology from the BBC.

At this time of year the Today Programme has guest editors, and this morning it was the turn of Charles Moore, the ex-editor of the Telegraph, sandwiched between four lefties (it’s Greta on Monday).

So today we heard from Matt Ridley. He made a number of good points in the limited time available. He talked about the diesel fiasco, in which polluting diesel cars were promoted by the green lobby because they produce slightly less carbon dioxide. He called out the extremist wing of climate science, mentioning Kevin Anderson and his exaggerated claims of warming. Roger “Friends of the Earth says” Harrabin also got a mention for his biased activism, as recently highlighted on this blog.

Ridley was followed by David King, who stubbornly denied the diesel issue, falsely claimed that Arctic ice was decreasing faster than any climate scientists thought, and made the untrue statement that we were on course for 1-2m of sea level rise this century.
