The supporters of man made climate change have had to endure a blizzard of bad public relations in the last few months of 2009. Examples include the furore over the Climate Research Unit data breach, sometimes referred to as Climategate, and the lack of a meaningful agreement at the UN Climate Summit at Copenhagen. The end of '09 and the start of the new decade is not being any kinder. The coldest December in 14 years with the ensuing chaos on road, rail, sea and air makes selling the idea of global warming just that little bit more difficult.
