The themes being considered are: 1. Uncertainty and risk 2. Regional integration 3. Water 4. Key vulnerabilities (including issues relating to Article 2 of the UNFCCC) 5. Adaptation and mitigation 6. Sustainable development 7. Technology Scoping papers are now being prepared to elaborate how these themes might be used in the assessment. These scoping papers are expected to be from 5 to 20 pages in length and are to be reviewed by a small number of experts before being considered further at the Second Scoping meeting for the AR4 in September. We would be very grateful if you would agree to act as a reviewer for the scoping paper on the Uncertainty and risk theme. The review period will be from the first week of June to June 27th. Given the potential importance these themes to the assessment process we believe it is important that they be subject to careful review. It would be especially helpful if your review would help us to evaluate the likelihood that such a theme would be useful in cutting across Working Group reports, and provide any requirements that you may see for ensuring a sound, scientific basis for such cross-cutting. We believe that you can aid us in carrying out such a careful review and in doing so you would be helping us to improve the quality of the report. Could you please confirm by May 30 whether you are able to assist us with this review.
