From Mr Ake Nilson.

Sir, In your editorial "It's time to plan for the next deluge" (July 25) you say that "it is now scientifically incontrovertible that global warming is making heavy rain fall more frequently across the world's temperate latitudes". But less than a year ago, on August 10 2006, you reported: "This year's hot, dry summer will be repeated many times in the future and will become normal in the next 40 to 50 years if climate scientists are correct."
