  Global Warming 'Will Spark More Hurricanes'

  The violence and frequency of hurricanes will increase with global warming, the Government's chief scientific adviser warned today.

  Sir David King issued his warning as Hurricane Rita menaced America's Gulf Coast and the heart of the US oil-refining industry, hard on the heels of Hurricane Katrina, which devastated the city of New Orleans and surrounding areas.

  Interviewed on BBC Radio 4's Today programme, Sir David also cautioned that the current spate of high-powered hurricanes is likely to continue into next month.

  Sir David said: "There is no question that intensity of hurricanes is dependent on surface sea temperature.

  "What we have seen in the Gulf of Mexico this year in August, surface sea temperatures were two to three degrees centigrade warmer than usual.

  "This means this is potentially an extreme event in terms of hurricane generation, so in that sense it is no surprise that we are seeing these intense hurricanes.

  "Across the central Atlantic sea temperatures will probably continue to be about one degree centigrade above normal right through to the end of this month, into October, which means that we can also anticipate that hurricanes will continue over that period at this intensity.

  "The point is that there is nobody arguing that(higher)sea temperature does not create more intense hurricanes. And as we then move forward in time, and the planet continues to warm up, we have therefore got to anticipate... that hurricane intensity, the baseline intensity of hurricanes will increase."

  Sir David added: "If in 50 years' time the average temperatures are a further one degree centigrade up, the conclusion is inescapable that there should be more of this kind of activity."
