"their suggestion that Jones and others were doing nothing more than “discarding data known to be erroneous” is simply absurd. There was no testimony to the Committee (nor has it ever been suggested) that the tree ring data was measured incorrectly or that the data was “erroneous” – the data is what it is. The tree ring data goes down instead of up – but that doesn’t make it “erroneous”. It only means that the data is a bad proxy – something that was concealed from IPCC readers. It is discouraging to read such bilge."
