[...]Saying no to Copenhagen and cap and tax are first steps in “restoring science to its rightful place.”
Un ex-CRU, Mike Hulme dice
"One thing the episode has made clear is that it has become difficult to disentangle political arguments about climate policies from scientific arguments about the evidence for man-made climate change and the confidence placed in predictions of future change. The quality of both political debate and scientific practice suffers as a consequence."
Esa frase de Sarah Palin es un magnífico ejemplo de esa confusión.
Por cierto, como ejemplo de radicalismo, propaganda, prepotencia, sesgo y manipulaciónn las palabras de Hulme
Science never writes closed textbooks. It does not offer us a holy scripture, infallible and complete. This is especially the case with the science of climate, a complex system of enormous scale, at every turn influenced by human contingencies. Yes, science has clearly revealed that humans are influencing global climate and will continue to do so, but we don't know the full scale of the risks involved, nor how rapidly they will evolve, nor indeed—with clear insight—the relative roles of all the forcing agents involved at different scales.
Similarly, we endow analyses about the economics of climate change with too much scientific authority. Yes, we know there is a cascade of costs involved in mitigating, adapting to or ignoring climate change, but many of these costs are heavily influenced by ethical judgements about how we value things, now and in the future. These are judgments that science cannot prescribe.
The central battlegrounds on which we need to fight out the policy implications of climate change concern matters of risk management, of valuation, and political ideology. We must move the locus of public argumentation here not because the science has somehow been "done" or "is settled"; science will never be either of these things, although it can offer powerful forms of knowledge not available in other ways. It is a false hope to expect science to dispel the fog of uncertainty so that it finally becomes clear exactly what the future holds and what role humans have in causing it. This is one reason why British columnist George Monbiot wrote about climategate, "I have seldom felt so alone." By staking his position on "the science," he feels alone and betrayed when some aspect of the science is undermined.
If climategate leads to greater openness and transparency in climate science, and makes it less partisan, it will have done a good thing. It will enable science to function in the effective way it must do in public policy deliberations: Not as the place where we import all of our legitimate disagreements, but one powerful way of offering insight about how the world works and the potential consequences of different policy choices. The important arguments about political beliefs and ethical values can then take place in open and free democracies, in those public spaces we have created for political argumentation.
