When you survey the trail of wreckage left by the climate emails crisis, three things become clear. The first is the tendency of those who claim to be the champions of climate science to minimise their importance. Those who have most to lose if the science is wrong have perversely sought to justify the secretive and chummy ethos that some of the emails reveal. If science is not transparent and accountable, it's not science.
I believe that all supporting data, codes and programmes should be made available as soon as an article is published in a peer-reviewed journal. That anyone should have to lodge a freedom of information request to obtain them is wrong. That the request should be turned down is worse. That a scientist suggests deleting material that might be covered by that request is unjustifiable. Everyone who values the scientific process should demand complete transparency, across all branches of science.
The second observation is the tendency of those who don't give a fig about science to maximise their importance. The denial industry, which has no interest in establishing the truth about global warming, insists that these emails, which concern three or four scientists and just one or two lines of evidence, destroy the entire canon of climate science.
Even if you were to exclude every line of evidence that could possibly be disputed – the proxy records, the computer models, the complex science of clouds and ocean currents – the evidence for man-made global warming would still be unequivocal. You can see it in the measured temperature record, which goes back to 1850; in the shrinkage of glaciers and the thinning of sea ice; in the responses of wild animals and plants and the rapidly changing crop zones.
