Met Office model is sunk by its own data

Christopher Booker, Telegraph
We are familiar with how consistently the Met Office has, in recent years, been getting its seasonal and medium-term weather forecasts so spectacularly wrong. We recall that soaking “barbecue summer” of 2009; their “warmer than average” December 2010, which turned out to be the coldest on record; last year’s “drier than average winter”, which led to the wettest January ever; and many more....... 
One reason this is significant, as I noted last year, is that it yet again confirms how seriously the Hadley Centre’s forecasting strategy has been skewed – by the way its computer models are programmed to assume that a steady rise in CO2 levels must inevitably lead to rising temperatures. This is the core reason why it has been getting all those forecasts of “hotter summers” and “drier winters” so dismally wrong.
A second point of concern is that the same unquestioned assumption has been allowed damagingly to reshape the energy policy of so many governments, above all our own. Yet, such is the power of group-think, not one of our leading politicians, from Barack (“the science is settled”) Obama down, has had the independence of mind to question that flawed assumption.
A third lesson that might emerge from this is that we should recognise that the Met Office’s blind acceptance of this scientific error has – in view of the disastrous influence it exerts on public policy – become a national scandal. In that popular buzz-phrase, the Met Office, for which we pay £200 million a year, has shown itself to be “not fit for purpose”. Yet never, by politicians or even the media, has there been any proper attempt to call it to account."
