I love this cartoon from Australia as it harks on to another bugbear of the media hype. The regular depiction of the vapour from cooling towers being photoshopped to show black smoke or photographed in such a way as the light gives that impression. Funnily enough water vapour is our largest greenhouse gas and yet we know little about it. However I would add a footnote to this picture which is something that every commentator should remember.
CO2 is not a Poison, it is not a Pollutant. It is a staple of life itself!
