This cartoon by Morten Morland from The Times shows a man in the street shouting out various conspiracy theories, such as Elvis Lives and The Moon Landing Never Happened. Nobody is taking any notice of him. However, when he claims that 'Man-Made Climate Change is a Hoax', he is quickly surrounded by reporters and TV crews.
The cartoon is a comment on the amount of publicity which is being given by the media to those who believe that anthropogenic (i.e., man-made) global warming is a hoax. In fact, many commentators have seized on the Climategate controversy to cast doubts on the scientific consensus which says that global warming is caused by man (see here and here). The sceptics seem to be gaining ground—according to a new poll, only one in two UK voters accepts man-made climate change.
