Weather Records are a STATE SECRET

The United Nations' Intergovernmental Panel on Climate Change (IPCC) computer models have proved just as wrong in predicting global temperatures as the Met Office has been in forecasting those mild winters and heatwave summers, says Christopher Booker of The Telegraph.

Everyone has enjoyed the discomfiture of the Met Office, caught out over its April forecast that we were in for a "barbecue summer" – not least because this is the third year running that our weathermen have got their predictions for both summer and winter hopelessly wrong. In 2007 and 2008 they forecast that summers would be warmer and drier, and winters milder than average – just before temperatures plunged and the heavens opened, deluging us with abnormal rain or snow according to season.

"When Mr McIntyre made Freedom of Information requests to see the data used to construct the HadCrut record (as he has chronicled on his ClimateAudit blog) he was given an almighty brush-off, the Met Office saying that this information was strictly confidential and that to release it would damage Britain's "international relations" with all the countries that supplied it."

One cause of the blunders that have made the Met Office a laughing stock is less widely appreciated, however. It is that the multi-million pound computer it uses to assist its short-term forecasting for Britain is also one of the four main official sources of data used by the UN's Intergovernmental Panel on Climate Change (IPCC) to predict global warming. In this respect the IPCC's computer models have proved just as wrong in predicting global temperatures as the Met Office has been in forecasting those mild winters and heatwave summers.
