Respecfully, why is the greatest scientific communicator in the world wasting his time on religion, instead of awakening people to the danger of climate change? We must hope the sceptics are right, but the unwelcome fact is that most of the scientists don’t think they are. Unless we act firmly and decisively now it is at least possible that starvation will get far worse and our children inherit a terrible future in a devastated world. The sceptics are winning the climate debate. The scientists have been comprehensively defeated by the journalists. Why is this great and wonderful writer not coming to the aid of his fellows?
