Who do you turn to when you want to blow wide open the conspiracy that is global warming? That's right. Jesse "The Body" Ventura — the man who has variously been a special forces operative, motorcycle gang member, WWF wrestler and governor of Minnesota, and who now promotes himself as a seeker of the "truth" in a new TV show called Conspiracy Theory with Jesse Ventura.

Having completed the job of exposing the 9/11 conspiracy in the previous episode of the series for the US cable network truTV (slogan: "Not Reality. Actuality"), last week Ventura set his investigative sights on global warming. In just 60 minutes, he proved once and for all that we've all been duped by a small cabal of profiteers obsessed with creating a new world order. The whole scam, according to Ventura and his team of investigators who interview a smorgasbord of expert witnesses, can be pinned on just two men — Sir Maurice Strong , a former UN bigwig, and Edmond de Rothschild , the late billionaire banker. They, the programme alleges, dreamt up the whole thing and duped the world into believing that carbon emissions are driving up global temperatures just so they could profit from carbon trading.

Quite a bold claim, so you would expect the programme to be positively dripping in hard evidence of such skulduggery. Ah, that's where things begin to unravel a little for Ventura. The programme is, in fact, little more than an unchallenged airing for a veritable Who's Who of climate scepticism. This is probably the most blatantly one-sided "documentary" on climate change since filmmaker Martin Durkin's now-notorious Great Global Warming Swindle first aired in 2007. That Martin Durkin himself appears in Ventura's investigation as an expert witness speaks volumes.

But joining Durkin in this hit job are MIT's sceptic-in-chief Richard Lindzen , Newsbuster's Noel Shepard (although he's just described as an "investigative reporter"), right-wing shock jock and PrisonPlanet.com editor Alex Jones , and, of course, Viscount Monckton of Brenchley, who boldly testifies that there has been collusion between government officials, scientists and businessmen to develop the theory of global warming simply in order to make money. Little, if any, room is given throughout the programme to airing any defence of the accused. Instead, the programme takes on the veneer of an undercover cop show, with frankly hilarious scenes in which Ventura and his investigators are seen meeting shadowy characters in car parks and warehouses to receive tip-offs about who to chase down.

One scene in particular will divert the attention of any British viewer. In a mystifying bit of casting, June Sarpong is hired as one of Ventura's investigators to interview a scientist who is living incognito in the "wilderness" for fear of his life because he holds the view that the sun, not carbon emissions, is driving global temperatures up. To the uninitiated, Sarpong is best known in the UK as a former presenter of a youth entertainment programme called T4 , who has interviewed, among others, Tony Blair and Al Gore (who, unsurprisingly, is one of the targets in Ventura's programme).

In 2007, she was awarded an MBE for "services to broadcasting and charity". What's more, she co-hosted the UK leg of Live Earth from Wembley Stadium in 2007 and her website says that her production company Lipgloss Productions has a TV series about climate change "in the pipeline". All of which begs the question: what on earth led her to get involved in this transparent piece of unsubstantiated propaganda?
