At least six people have been hurt by a tornado that hit a street in Kensal Rise in north west London today. This is bizarre and worrying — I don’t remember ever hearing about tornadoes in the UK before. This report in the Guardian Unlimited expresses the concern very succinctly:

Until recently tornados were extremely rare in Britain. But in the last 18 months a number have arrived, prompting warnings that such freak weather events are likely to increase in frequency because of global warming.
