Richard Tol, Hans von Storch and I have an op-ed in Der Spiegel on the troubled IPCC. Here is an excerpt:Please have a look and feel free to come back and discuss.It will take many electoral cycles and all major countries to address the problems associated with climate change. Partisan advice will be unpicked, sloppy research will be exposed. New observations and theory will change aspects of the current understanding. Sustaining a climate policy that is effective, acceptable and durable can only be based on sound and impartial advice from institutions that do their science sustainably over many decades. The IPCC was supposed to provide that advice, but its standards have slipped, its procedures have turned out to be insufficient and its credibility has been questioned.
Climate policy matters, and so too does the IPCC. Its importance means that reform is needed before the reputation of all of climate science is irreparably damaged.
