The burden of proof

Remember who needs to persuade who on climate change

I have just one comment on the Climategate reports and that is this.

People who ask the world to spend $45 trillion on a project are surely under an obligation to show their raw data and their workings. If instead, they

publish only `adjusted data' rather than raw data,

refuse reasonable requests for computer code,

break freedom of information laws,

use `tricks' to `hide' inconvenient data,

base an argument on one tree,

use inappropriate statistical techniques,

break their own rules on sources,

and urge each other to delete rather than release correspondence,

then I don't think they should go to jail or be called frauds.

But I do think their request should be politely turned down.
