In case you missed it. I meant to write about this a couple of days ago when I first read of it (thanks to the IPCC vice-chair Jean-Pascal van Ypersele and Leo Hickman).
At it's recent meeting the IPCC made five noteworthy decisions, as reported by Roz Pidcock at the Carbon Brief. They are:
1. Major comprehensive reports will continue to be produced every five to seven years.
In between there may be more special reports. For example, there has been a request for a report on oceans.
2. There may be a bit more time allowed between the reports from different working groups
However, the time span between the release of WG1 to WGIII won't be any longer than 18 months.
3. Science writers and graphic designers will contribute to the Summary for Policy Makers.
This is excellent news. I've said before that science communicators ought to be used to translate the science. Scientists will have the overall say and will sign off on reports (as will governments when it comes to the SPM, as always).
4. The IPCC will put more effort into communication activities
Again, excellent news. There is talk of an offer from the Norwegian government, to hold a workshop for scientists to discuss such things. The IPCC hasn't yet made a decision on whether to take up this offer.
5. More participation from developing countries
Again, this is a great move. Developing countries will be hit hardest by climate change. The IPCC is expanding the size of the bureau by two, to include more representatives from Africa and Asia. It's also "exploring the possibility" of holding more meetings in developing countries.
You can read more detail about this at the Carbon Brief.
You might also be interested in an article by Marianne Lavelle at The Daily Climate, which includes a discussion of how to better incorporate social and political sciences and economics into the IPCC reports. This I believe, relates in part to this memo from Carlo Carraro, Charles Kolstad, and Robert Stavins. You may recall Robert Stavins wrote a blog article in April last year, that got a bit of attention.
