The Met Office today released temperature records from more than 1,500 climate monitoring stations around the world in the latest efforts to debunk claims by sceptics that global warming data was manipulated by scientists.
The raw data comes from a network of individual stations which have been used by the World Meteorological Organisation to monitor global surface temperatures.
According to the Met Office, the records from the 1,500 sites show that temperatures have risen over the past 150 years.
The results from the monitoring centres released today is very similar to the complete set of data records from around 5,000 stations which the Met Office's Hadley Centre and the University of East Anglia's Climatic Research Unit (CRU) use to measure global land temperatures in the "HadCrut" record.
The data released today, a subset of the total from the 5,000 sites, is not a new global temperature record and does not replace the HadCrut record or other analyses from Nasa or the National Climatic Data Centre in the US.
The Met Office said it would release the data from the remaining station records when it had permission from those centres to do so.
And scientists said they would publish "as soon as possible" the specific computer code that aggregates the individual station temperatures into the global record. …
