"The Great Global Warming Swindle" is a Swindle

The film's key contention was that the increase in atmospheric temperatures observed since the 1970s was not primarily caused by emissions of greenhouse gases from burning fossil fuels.

First aired by Channel 4 in March 2007, the documentary has since reportedly been sold to 21 countries and distributed on DVD.

Dr Wunsch, from the Massachussetts Institute of Technology, said he believed he was being asked to take part in a programme that would "discuss in a balanced way the complicated elements of understanding of climate change", but "what we now have is an out-and-out propaganda piece, in which there is not even a gesture toward balance".

The Broadcasting Code requires Channel 4 to show "due impartiality" on "matters of major political and industrial controversy and major matters relating to current public policy".

The last segment of the programme, dealing with the politics of climate change, broke this obligation, Ofcom judged, and did not reflect a range of views, as required under the code.

MythBuster: Why Electric Vehicles Beat Gas in 5 Extreme Tests


I'm really big on electric vehicles because the total amount of fuel consumption involved is much less than what gas vehicles consume thanks to the efficiencies involved in a power generating plant. But there's a lot of talk out there that electric vehicles just don't perform as well as their gas counterparts—and, because we want to keep the planet intact, it sounded like a good myth to bust. So we decided to put gas and electric models of compact cars, ATVs, motorcycles and go-karts head-to-head on the track and the road to figure out if electric could hold its own.

Besides almost zero emissions, electric vehicles also have some very distinct advantages: An electric ATV is quiet, healthier to have around crops, and you don’t need it to go 300 miles on a charge. Barefoot’s prototype is running 2.5 hours of average use on a charge and is back to 80 percent charge over a lunch break, which is more than adequate run time on a farm or vineyard. Our highways and neighborhoods will be quieter and cleaner with electric cars and motorcycles on them.

Building an electric go-kart or ATV is not any more difficult than making a radio-control electric car. Sure, we’re using welders instead of pre-made plastic parts, but you’ve got an electric motor, a bank of batteries and a speed controller. Look at your racing RC toys—it’s the same thing. The home-built electric car we tested had serious limitations, but I think I could build one that doesn’t have those problems. I fully intend to make a full-size electric car; I figure it’d take about $28,000 worth of components for a plus-300-mile range. It should take me about a week or two to build—tops.
