Sir John Beddington's retirement is now only a few weeks away and he is taking the opportunity to warn everyone, just one more time, that the end of the world is nigh. On about three or four dozen different fronts.
In his speech to the Royal Academy of Engineering a few days ago he had this to say.
Sir John warned that low probability, high impact events are becoming increasingly frequent, and highlighted other concerns such as space weather events and unexpected effects from computer trading in financial markets.
Is there any empirical evidence to support this claim? Any at all?
