Dutch scientist and chemical engineer Dr. Arthur Rörsch has distributed a working paper to Dutch officials in his country to request a comprehensive review of the results and recommendations of the IPCC, especially its upcoming 5th assessment report.H/t: http://www.kaltesonne.de/?p=926:

In his paper Rörsch, former vice-president of the Netherlands Organisation for Applied Research, writes that the IPCC has “deviated from the traditional scientific principles”. On man-made warming from CO2, he writes “that no indisputable scientific proof, or even strong empirical evidence, has been provided for such an effect, which therefore remains a matter of speculation.”

He adds:

These reviews would best be undertaken by senior and established scientists whose reputation rests in the traditional enabling disciplines that underpin climate science, specifically physics, chemistry, geology and meteorology.”

The draft volume for WG1 AR5 is a summary and compilation of papers published in scientific journals up to 2011. Rörsch makes two observations:

– The prevailing hypothesis of the assessment report is that Dangerous Anthropogenic Global Warming (DAGW) is occurring; this hypothesis has been under challenge for many years by numerous independent scientists. These scientists were not invited to participate in the preparation of the AR5 report.

– The scientific literature cited in the draft AR5 is selective towards papers that support the DAGW hypothesis, and even the papers that are included are then selectively analysed towards the same ends. These two underlying biases set the tone of the message that the authors of the AR5 report want to transmit.

Rörsch particularly criticizes the following points:

1. The IPCC assumes that atmospheric CO2 is a dominant forcing agent for global temperature without providing evidence.

2. The report authors are instructed to express their conclusions in terms of a qualitative (i.e. opinion-based) probability scale.

3. The IPCC’s use of “self-appointed experts”.

4. There’s arrogance and intolerance for alternative views displayed by the self-appointed climate experts. These experts should be treated with extreme suspicion.

5. The style of the draft AR5 report marks it as a political rather than a scientific document, for it has been fashioned within the framework of a particular cultural paradigm.

Here’s what Dr. Rörsch concludes:

The IPCC’s draft AR5 report shows insufficient objectivity, and lacks the ‘traditional’ scientific balance necessary for it to be used as the basis for policy making. Regrettably, the report exemplifies some of the worst features of the ‘post-modern’ approach to science…”
