Met Office reviews 150 years of climate

The UK Met Office will ferret back through 150 years of global temperature records to see if it missed anything first time around.

The decision was prompted by the East Anglian University kerfuffle that may have put doubt of the voracity of climate-change data into some feeble minds.

The Met Office assembled its data in ­collaboration with the the hacked Climatic Research Unit (CRU) at the University of East Anglia. Although it expects to find no change in implications of the data, the three-year mission might help re-convince the doubters of the reality of man-made global warming.

Scepticism of the reality of man-made climate change has increased since the clumsily-worded emails from the CRU were hacked and exposed.

"It is important to emphasise that we do not anticipate any substantial changes in the resulting global and continental-scale multi-decadal trends. This effort will ensure that the datasets are completely robust and that all methods are transparent," the Office wrote in the document - a Proposal for a New International Analysis of Land Surface Air Temperature Data - which it delivered to a meeting of the World Meteorological Organisation in Turkey earlier this week.

"To meet future needs to better understand the risks of dangerous climate change and to adapt to the effects of global warming, further development of these datasets is required, in particular to better assess the risks posed by changes in extremes of climate," the report states.
