The protest comes on the same day that the IPCC, the world's most respected climate change organisation, announced that global warming is worse than previously thought and 'unequivocally' man-made.

Coal, which contains 50% carbon, produces far more carbon dioxide than either oil or gas and is the largest contributor to global warming.
