For years the Wind Industry and the Greens have had the misguided obsession of telling us all to lower harmless carbon dioxide, yet totalling ignoring the higher emissions of harmful and the very real health threatening nitrogen oxide gasses.

Make no mistake for without carbon dioxide there would be no life, as we know it, on our planet - the Continentals know the worth of carbon dioxide by pumping this gas into their greenhouses to enhance plant growth! At last it has all now been exposed by the cheating of VW (of all companies) and readers should recognise that diesel fumes contain a cocktail of more than 40 toxic pollutants from the cancer causing benzene, arsenic and formaldehyde to the tiny sooty particulates and nitrogen oxides – compared to petrol engines, diesels produce 22 times as many particulates, and far more nitrogen oxides. Thus the exposure truly shows the idiocy behind the Kyoto protocol in 1997 and the commitment to reduce emissions of carbon dioxide to combat so-called global warming – where was the commitment to reduce diesel pollution - perhaps we can put the lunatics back into the asylum now?
