Raw climate data finally disgorged after lawsuit
Despite the huffing and puffing below I can see no legitimate reason why it was EVER withheld. Is the weather a secret?
It's going to be interesting to see how "raw" the data is. Some comparisons with independent records will be possible and past such comparisons have revealed huge manipulations. The Warmists below are gearing up for that
Anyone can now view for themselves the raw data that was at the centre of last year's "climategate" scandal.
Temperature records going back 150 years from 5113 weather stations around the world were yesterday released to the public by the Climatic Research Unit (CRU) at the University of East Anglia in Norwich, UK. The only records missing are from 19 stations in Poland, which refused to allow them to be made public.
"We released [the dataset] to dispel the myths that the data have been inappropriately manipulated, and that we are being secretive," says Trevor Davies, the university's pro-vice-chancellor for research. "Some sceptics argue we must have something to hide, and we've released the data to pull the rug out from those who say there isn't evidence that the global temperature is increasing."
Hand it over
The university were ordered to release data by the UK Information Commissioner's Office, following a freedom-of-information request for the raw data from researchers Jonathan Jones of the University of Oxford and Don Keiller of Anglia Ruskin University in Cambridge, UK.
Davies says that the university initially refused on the grounds that the data is not owned by the CRU but by the national meteorological organisations that collect the data and share it with the CRU.
When the CRU's refusal was overruled by the information commissioner, the UK Met Office was recruited to act as a go-between and obtain permission to release all the data.
Poland refused, and the information commissioner overruled Trinidad and Tobago's wish for the data it supplied on latitudes between 30 degrees north and 40 degrees south to be withheld, as it had been specifically requested by Jones and Keiller in their FOI request and previously shared with other academics.
The end result is that all the records are there, except for Poland's. Davies's only worry is that the decision to release the Trinidad and Tobago data against its wishes may discourage the open sharing of data in the future. Other research organisations may from now on be reluctant to pool data they wish to be kept private.
Thomas Peterson, chief scientist at the National Climatic Data Center of the US National Oceanographic and Atmospheric Administration (NOAA) and president of the Commission for Climatology at the World Meteorological Organization, agrees there might be a cost to releasing the data.
"I have historic temperature data from automatic weather stations on the Greenland ice sheet that I was able to obtain from Denmark only because I agreed not to release them," he says. "If countries come to expect that sharing of any data with anyone will eventually lead to strong pressure for them to fully release those data, will they be less willing to collaborate in the future?"
Davies is confident that genuine and proper analysis of the raw data will reproduce the same incontrovertible conclusion - that global temperatures are rising. "The conclusion is very robust," he says, explaining that the CRU's dataset of land temperatures tally with those from other independent research groups around the world, including those generated by the NOAA and NASA.
"Should people undertake analyses and come up with different conclusions, the way to present them is through publication in peer-reviewed journals, so we know it's been through scientific quality control," says Davies.
No convincing some people
Other mainstream researchers and defenders of the consensus are not so confident that the release will silence the sceptics. "One can hope this might put an end to the interminable discussion of the CRU temperatures, but the experience of GISTEMP - another database that's been available for years - is that the criticisms will continue because there are some people who are never going to be satisfied," says Gavin Schmidt of Columbia University in New York.
"Sadly, I think this will just lead to a new round of attacks on CRU and the Met Office," says Bob Ward, communications director of the Grantham Research Institute on Climate Change and the Environment at the London School of Economics. "Sceptics will pore through the data looking for ways to criticise the processing methodology in an attempt to persuade the public that there's doubt the world has warmed significantly."
The CRU and its leading scientist, Phil Jones, were at the centre of the so-called "climategate" storm in 2009 when the unit was accused of withholding and manipulating data. It was later cleared of the charge.
