Climate change is clearly the bandwagon to be on at the moment. The new green-blue Tories (what colour of the political spectrum does that make them - aquamarine?) have muscled their way on board, the media is transmitting the message on all channels, and even celebrities like Thandie Newton are climbing aboard. To my knowledge, we haven't got Jimmy Carr yet but he pops up on everything else so it's only a matter of time.
