Why do the Met Office get their forecasts so wrong?

I have explained before why this might be the case, adherence to dogma outweighing science, but here is Christopher Booker. Do read the whole article but here's an extract:

'The reason why the Met Office gets its forecasts so hopelessly wrong is that they are based on those same computer models on which the IPCC itself relies to predict the world’s climate in 100 years time. They are programmed on the assumption that, as CO2 rises, so temperatures must inexorably follow. For 17 years this seemed plausible, because the world did appear to be getting warmer. We all became familiar with those warmer winters and earlier springs, which the warmists were quick to exploit to promote their message – as when Dr David Viner of the CRU famously predicted to The Independent in 2000 that “within a few years winter snowfall will be a very rare and exciting event”. (Last week, that article from 10 years ago was the most viewed item on The Independent’s website.)

But in 2007, the computer models got caught out, failing to predict a temporary plunge in global temperatures of 0.7C, more than the net warming of the 20th century. Much of the northern hemisphere suffered what was called in North America “the winter from hell”. Even though temperatures did rise again, in the winter of 2008/9 this happened again, only worse.

The Met Office simply went into denial. Its senior climate change official, Peter Stott, said in March 2009 that the trend towards milder winters was likely to continue. There would not be another winter like 1962/3 “for 1,000 years or more”. Last winter was colder still. And now we have another even more savage “random event”, for which we are even less prepared. (The Taxpayers’ Alliance revealed last week that councils have actually ordered less salt this winter than last.)

The consequences of all this are profound. Those who rule over our lives have been carried off into a cloud-cuckoo-land for which no one was more responsible than the zealots at the Met Office, subordinating all it does to their dotty belief system. Significantly, its chairman, Robert Napier, is not a weatherman but a “climate activist”, previously head of WWF-UK, one of our leading warmist campaigning groups.'
