A few weeks ago I attended an IPCC1 Fifth Assessment Working Group expert review meeting for the upcoming Fifth Assessment Report (AR5) (WG III – Mitigation: the ‘first order draft’ is now being reviewed with the final report to be published in 2014). This meeting was a typical collection of about 100 climate researchers from around the world, this time, conveniently in Washington, DC. The overall Assessment Report process involves about 30 to 40 such meetings around the world per year. Part of their function is for the Assessment Reports to feed into the UNFCCC negotiation process.
Despite its challenges, complexities and occasional politicization, the IPCC is a wonderful idea. Credible researchers, no-matter where they live or work, are asked to contribute to a body of science larger than any one country, company or agency. Any city should feel proud to have an employee participating in an IPCC review.
