In the open-source software community, we understand about human error and sloppiness and the tendency to get too caught up in a pet theory. We know that the most effective way way to combat these tendencies is transparency of process — letting the code speak for itself, and opening the sources to skeptical peer review by anyone.
There is only one way to cut through all of the conflicting claims and agendas about the CRU’s research: open-source it all. Publish the primary data sets, publish the programs used to interpret them and create graphs like the well-known global-temperature “hockey stick”, publish everything. Let the code and the data speak for itself; let the facts trump speculation and interpretation.
If the AGW advocates are confident in their position they will disclose their data. When you consider the ramifcations of global warming, including drastic new taxation schemes, there really is no alternative for informed debate and consideration. If they refuse we can reasonably presume they are being less than forthright with their data, analysis, and agenda.
