Met office to publish warming data
The Met Office will this week publish some of the data which it uses to analyse global warming.
Information collected by more than 1,000 weather stations from across the world will be released, a spokesman said.
The publication follows this week's claims from climate change sceptics that researchers have manipulated evidence to support a theory of man-made global warming.
The claims are based on emails and other material, stolen from servers at the University of East Anglia's Climatic Research Unit and posted online, in a row which has been dubbed "Climategate".
Dr Rajendra Pachauri, chairman of the UN's Intergovernmental Panel on Climate Change (IPCC), told BBC Radio 4's The Report programme that the claims were serious and would be looked at "in detail".
The Met Office's database is a main source of analysis for the panel.
A Met Office spokesman said: "The Met Office does intend to release data from more than 1,000 weather stations.
"It will be available on our website."
He said the Met Office had "every confidence" in the data which would show that global temperatures had warmed up over the last 150 years.
Further information may be released at a later date after the Met Office wrote to 188 countries for permission to publish the remainder of the historic data.
