I was really worried until I looked out the window this morning – and then I realised I'd got it completely wrong about global warming. This is quite the best evidence you can get that we are about to fry. All my doubts and uncertainties have vanished.
Mind you, the snow hasn't reached London yet, so it hasn't officially happened. But then, according to the Met Office, this hasn't happened. This is actually rain you are seeing - although the BBC is up to speed.
