UN science chief defends IPCC-UN Intergovernmental Panel on Climate Change's work and welcomes review

AMSTERDAM, Friday 14 May – The head of the U.N. scientific body on climate change defended the work of the thousands of scientists who contribute to its reports, even as he welcomed a review of procedures that produced errors undermining the panel's public credibility.

The chairman of the Intergovernmental Panel on Climate Change, Rajendra Pachauri, cautioned an independent scientific committee reviewing the IPCC's work not to undermine scientists' motivation for contributing to reports on global warming.

Recently its reports have been dismissed (undermined) by climate skeptics who attribute global warming to natural cycles. The skeptics were bolstered by a series of errors in the IPCC's 2007 report.

Pachauri told the committee's first review meeting that the panel's conclusions are valid, even in areas where mistakes were discovered.

Pointing to the most glaring error, a claim that the world's glaciers will melt by 2035, Pachauri said glaciers are indeed melting, though not that fast. Nonetheless, glacial melt accounts for 28 percent of sea level rise, and the panel's assessment on glaciers contains "a lot of facts which we can ignore at our peril."

Pachauri said the panel is comprised of volunteer scientists contributing several years of their own time and who disband after issuing their report. The panel has no mechanism for responding to criticism once the reports are issued, other than the small secretariat.

"We need to develop an ability and a capacity to communicate better with the outside world," he told the 15 top scientists from around the world summoned to sit on the review committee..

He said the panel's procedures already are robust, but he welcomed any suggestion that would improve accuracy.

The review is expected to take several weeks before it issues recommendations on how to tighten the IPCC procedures.

Its up to the individual whom he chooses to believe in these issues.

He can choose between either the largest body of the worlds best and most recognised scientists and experts of all times brought together to study this most important or a relatively small number of specialist sceptics and a large number of lay persons with little or no recognised scientific or engineering training in such vast and complex fields as to the probable outcomes.

I know which group I would choose to place my faith.

Adrian Bejan - Constructal Theory, Fundamental and Philosophical

In order to look at some of the more fundamental and philosophical aspects in materials science and processing I have modified the Phil Trans A link list to "Fundamental and Philosophical" in order to treat subjects such as Thermodynamics: Entropy,Exergy,open and closed systems and here Adrian Bejan's Constructal theory. Two links may be found on the links list:
1.Adrian Bejan's Constructal Theory website.

2. Philosophical Transactions of the Royal Society B - The Constructal Law of Design and Evolution in Nature_PDF

Materials and Environment-Embodied Energy of Materials

I kicked-off this link series Materials and Environment-Embodied Energy, fittingly with reference to the excellent book "Materials and Environment" by MF Ashby, M. F. Ashby, Daniel L. Schodek, Paulo J. S. G. Ferreira to which I added diverse previous blog post references. The list at present has an additional five links for menory:
1. Embodied Energy-Wikipedia-A place to start your search


2. Embodied Energy Materials Coefficients PDF_NZ source

3. Embodied Energy Steel_Australian Source

4. Energy Use & CO2 emissions:Steel Sector-PDF

5. Whole-life costs: Concrete vs steel

Hopefully this list will lengthen with time, rapidly due to the inceasing importance in todays global economy.
