Yet it is only two years since the Met Office was boasting of the £33 million supercomputer, the most powerful in Britain, that it had installed in Exeter. This, as Prof Slingo confirmed to the parliamentary inquiry into Climategate, is what provides the Met Office both with its weather forecasting and its projections of what the world’s climate will be like in 100 years (relied on, in turn, by the UN’s Intergovernmental Panel on Climate Change). Prof Slingo fails to recognise that the fatal flaw of her computer models is that they assume that the main forcing factor determining climate is the rise in CO2 levels. So giving her yet more money would only compound the errors her computers come up with.
