“The World’s Source for Global Temperature Record Admits It’s Lost or Destroyed All the Original Data That Would Allow a Third Party to” Model Climate

According to the Register [2]:

The world’s source for global temperature record admits it’s lost or destroyed all the original data that would allow a third party to construct a global temperature record. The destruction (or loss) of the data comes at a convenient time for the Climatic Research Unit (CRU) in East Anglia – permitting it to snub FoIA requests to see the data.

The CRU has refused to release the raw weather station data and its processing methods for inspection – except to hand-picked academics – for several years. Instead, it releases a processed version, in gridded form. NASA maintains its own (GISSTEMP), but the CRU Global Climate Dataset, is the most cited surface temperature record by the UN IPCC. So any errors in CRU cascade around the world, and become part of “the science”.

Professor Phil Jones, the activist-scientist who maintains the data set, has cited various reasons for refusing to release the raw data. Most famously, Jones told an Australian climate scientist in 2004:

Even if WMO agrees, I will still not pass on the data. We have 25 or so years invested in the work. Why should I make the data available to you, when your aim is to try and find something wrong with it.

In 2007, in response to Freedom of Information Act requests, CRU initially said it didn’t have to fulfil the requests because “Information accessible to applicant via other means Some information is publicly available on external websites”.

Now it’s citing confidentiality agreements with Denmark, Spain, Bahrain and our own Mystic Met Office. Others may exist, CRU says in a statement, but it might have lost them because it moved offices. Or they were made verbally, and nobody at CRU wrote them down.

As for the raw station data,

“We are not in a position to supply data for a particular country not covered by the example agreements referred to earlier, as we have never had sufficient resources to keep track of the exact source of each individual monthly value. Since the 1980s, we have merged the data we have received into existing series or begun new ones, so it is impossible to say if all stations within a particular country or if all of an individual record should be freely available. Data storage availability in the 1980s meant that we were not able to keep the multiple sources for some sites, only the station series after adjustment for homogeneity issues. We, therefore, do not hold the original raw data but only the value-added (i.e. quality controlled and homogenized) data.”

Even if the Register is accurately reporting the story, I have no idea whether the motivations of the scientists at CRU are noble or not.

More importantly, I have no idea whether CRU has accurately summarized the original data. A careful and ethical scientist could do so, but a sloppy or unethical scientist might end up with different values than the actual data set.

My views on climate are complex [4]. But the one thing I know for sure is that we need accurate data, because the stakes are high.
