From Kate at Small Dead Animals: No U-turns allowed
I find it hard to believe that the British Antarctic Survey would permit the deletion of relevant files for two recent publications or that there aren’t any backups for the deleted data on institutional servers. Would you mind inquiring for me? In the mean time, would you please send me the PP format files that you refer to here for the monthly sea ice data for the 20th century models discussed in your GRL article and the 21st century models referred to in your JGR article.

Then in July… “Unprecedented” Data Purge At CRU
On Monday, July 27, 2009, as reported in a prior thread, CRU deleted three files pertaining to station data from their public directory ftp.cru.uea.ac.uk/. The next day, on July 28, Phil Jones deleted data from his public file – see screenshot with timestemp in post here, leaving online a variety of files from the 1990s as shown in the following screenshot taken on July 28, 2009.
The Telegraph, today – Climategate: University of East Anglia U-turn in climate change row ….. Leading British scientists at the University of East Anglia, who were accused of manipulating climate change data – dubbed Climategate – have agreed to publish their figures in full….
Now, here comes the other shoe! Hide the Decline!
SCIENTISTS at the University of East Anglia (UEA) have admitted throwing away much of the raw temperature data on which their predictions of global warming are based.
It means that other academics are not able to check basic calculations said to show a long-term rise in temperature over the past 150 years.
The UEA’s Climatic Research Unit (CRU) was forced to reveal the loss following requests for the data under Freedom of Information legislation.
The data were gathered from weather stations around the world and then adjusted to take account of variables in the way they were collected. The revised figures were kept, but the originals — stored on paper and magnetic tape — were dumped to save space when the CRU moved to a new building.”
In a statement on its website, the CRU said: “We do not hold the original raw data but only the value-added (quality controlled and homogenised) data.”
The CRU is the world’s leading centre for reconstructing past climate and temperatures. Climate change sceptics have long been keen to examine exactly how its data were compiled. That is now impossible.
