Alchemy and science

Last night the BBC ran a news item that stated that scientists had ‘proved’ that warming in the polar regions was due to man. Well, considering that scientists have not yet proved anthropogenic global warming to be real, this would prove to be a very interesting find indeed. The findings are published in Nature Geoscience as a letter, Attribution of polar warming to human influence.

Today, the news media are saturated with the hype, from which one would think that something really significant had been discovered. I found over 150 news articles being run from all over the world.

New study another ‘nail’ in debate over warming
Done. Proven. Humans are making the Arctic and Antarctica warm up. Case closed, says an influential group of climate scientists. – Ottawa Citizen

Climate change at the poles IS man-made
Scientists refute sceptics by proving that human activity has left its mark on the Arctic and Antarctic. – The Independent

‘Mankind is responsible for the warming up of the Antarctic, not just mother nature’ scientists say
The first hard evidence that mankind is responsible for the heating up of the Antarctic has been uncovered by Met office scientists. – Daily Mail

It’s Official: People Are Warming the Poles
The verdict is in. Warming near the poles is caused by human activity, according to new research. – Discovery Channel

Man is to blame for Antarctic temperature rise
Scientists say they now have conclusive proof that warming is due to man’s influence mainly through greenhouse gases and ozone depletion. – Daily Telegraph

Humans to blame for polar warming
Evidence has emerged that human activity, not natural phenomena, is directly responsible for heating up the polar ice caps. – New Scientist

Scientific proof that humans are causing polar warming
A new research has provided conclusive proof that human activity is responsible for significant warming in both polar regions. – Indian Express

Humans Guilty Of Melting Ice Caps
It’s official – humans are to blame for melting the ice caps as natural forces are not powerful enough to do it alone, a new experiment has revealed. – Sky News

So what is this amazing ‘conclusive proof’ from this ‘new experiment’? We find that there is no genuine evidence or proof at all. Quite simply, a computer model has had various ‘forcings’ tweaked – certain input variables adjusted – and when selected variabilities of a selected set of natural variations (e.g. in the sun and volcanoes) were entered, the output did not match the observed temperature, but when selected agents such as carbon dioxide, ozone and sulphate aerosols were added at selected amounts (all variations claimed to be due to man – but this is itself disputable), the model gave the ‘correct’ results. Well, what do you know! If you construct a model that is insensitive to natural variations and highly sensitive to man-made variations, it’s no surprise that the man-made variations create the most significant effect, and practically any effect can be said to be anthropogenic (man made). The authors declare:

We compare observed temperatures with simulations from four CMIP3-coupled climate models…To objectively test for the presence of an anthropogenic or natural response in observations of polar temperature, we use a detection and attribution analysis to compare simulated and observed changes. Such methods, first developed to detect anthropogenic influence on global temperature, have more recently been used to detect anthropogenic influence on temperature on continental scales.

But this is junk science. No climate model has in the past been anywhere close to predicting (i.e. arguing from causes to effects) what will happen to temperature as the variables are adjusted, so climate models are, to date, proven to be completely useless as models of reality. And analysis methods might very well have been ‘developed to detect anthropogenic influence on global temperature’, but they have spectacularly failed to be of any use in that for which they were developed used in conjunction with computer models. Therefore, arguing backwards via a flawed model and/or analysis from effect to cause is insanity, and any claim based on climate models that a certain observed phenomenon is caused by a certain ‘forcing’ (in this case man-made) is certainly spurious – be sure of it.

The Tyranny of the Scientific Consensus

Professor Paul Reiter, in his submission to the House of Lords Select Committee on Economic Affairs, declared

In the age of information, popular knowledge of scientific issues – particularly issues of health and environment – is awash in a tide of misinformation, much of it presented in the “big talk” of professional scientists. Alarmist activists operating in well-funded advocacy groups have a lead role in creating this misinformation. In many cases, they manipulate public perceptions with emotive and fiercely judgmental “scientific” pronouncements, adding a tone of danger and urgency to attract media coverage. Their skill in promoting notions of scientific “fact” sidesteps the complexities of the issues involved, and is a potent influence in education, public opinion and the political process.

In his testimony to the United States Senate he stated

A galling aspect of the debate is that this spurious ‘science’ is endorsed in the public forum by influential panels of ‘experts.’ I refer particularly to the Intergovernmental Panel on Climate Change (IPCC)… [which] publishes a ‘consensus of the world’s top scientists’ on all aspects of climate change…such consensus is the stuff of politics, not of science…A public that is unaware of this is vulnerable to abuse.

The so-called ‘scientific consensus’ is being used to ram through huge measures of political control. We are told that there is a scientific consensus on this or that, when there is no consensus at all. To question the consensus, or whether such a consensus exists, is to be a ‘denier’ or a modern-day heretic, who must be silenced, or at the very least humiliated. Scientists who challenge the ‘consensus’ are being increasingly marginalized, especially in areas where the big money is flowing to support a particular political line – for example, in the climate change area. Those who present evidence contrary to the so-called consensus are called ‘traitors’ ,

…and we need to start treating them like traitors

says Robert F. Kennedy Jr, so there are calls for them to be tried for treason, ‘crimes against humanity’ and genocide. As The Daily Telegraph reported last month of James Hanson, director of the NASA Goddard Institute for Space Studies:

Hansen has been for 20 years the world’s leading scientific advocate of global warming (and Al Gore’s closest ally). But in the past year a number of expert US scientists have been conducting a public investigation, through scientific blogs, which raises large question marks over the methods used to arrive at his figures…

Hansen himself is notoriously impatient of any criticism of his methods: earlier this month he appealed to Congress that the leaders of those who question global warming should be put on trial.
