The work of IPCC: a comment

The Dutch Planbureau voor de Leefomgeving has been charged with the evaluation of 'Climate Change 2007: Impacts, Adaptation and Vulnerability'. Outsiders have been invited to submit their comment to: . my comment did not comply with the 'rules'. Instead of helping to improve the 2007 report, it is rather a plea for a broader, critical assessment of the work of IPCC. Note that IPCC's auto-assessment is scheduled for 2013 and 2014.
By the way, 40 emails have been received about mistakes in the 2007 report.

The work of IPCC deviates from basic methodological rules. There are three major flaws:

1. Focusing on the global scale does not suffice: a multi-level analysis of environmental problems is called for on macro, meso and micro levels, but - in especial at the meso level of cities and regions.

2. Man-made CO2-induced global warming is basically a one-factor theory which tends to invite simple correlations a la Al Gore.

3. IPCC's handling of uncertainties leaves much to be desired.
