The wrong way to dump data

What is wrong with this statement?

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 order to be processed, the raw data have entered a computer once. If they were stored on paper, they were typed in. If they were stored on tape, they were read in. It is easy to write it all back out on tape. And we are not talking about huge amounts of data. You don’t need much storage room.

Combine that with this attitude:

I’ll delete the file rather than send to anyone

and you can almost perceive a fishy smell.

So, CRU temperature data is no longer trustworthy. Only two temperature data sets are left, NOAA and GISS. Only two, for one of the supposedly most urgent and serious problems of mankind! And when I read this (written by the figurehead of the denialists, admittedly):

The effect of the adjustments since 2000 has been to bring the USHCN history more in line with the CRU version.

I get a sinking feeling in the stomach.

Science, this ain’t.
