CRU Admits That They Threw Away The Original Data

CRU Admits That They Threw Away The Original Data

This just gets better and better. From the November 29, 2009 Sunday Times:
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.
Roger Pielke, professor of environmental studies at Colorado University, discovered data had been lost when he asked for original records. “The CRU is basically saying, ‘Trust us’. So much for settling questions and resolving debates with science,” he said.
Look, they have a plausible claim--that they threw away the originals way back when because of limited space, and what was then only an academic interest in temperature data. But if there is no way to recreate how they created their "value-added (quality controlled and homogenised) data," why should anyone believe them? Especially in light of these emails admitting that they were trying to prevent differing points of view from getting published?
