IPCC AR5 WG1 author shake up

So, after all the issues relating to the IPCC in recent months (e.g. the unimaginatively named “Climategate”, “Glaciergate”, the now retracted “Amazongate” and the not-so-heavily-covered-…-I-wonder-why? “SeaLevelGate”) the wheel keeps on turning and we’re looking at another IPCC report in 2013.

How have things changed with the IPCC? Have they made any effort to change after all the negative publicity?

Well, the IPCC issued the list of chapters and authors for the Fifth Assement Repoert (AR5) and I thought I’d have a quick look at what’s new. I’ve only looked at WG1 because that’s what I know and what I find most interesting.

“Clouds and aerosols” get their own chapter and regional climate change is mentioned, which are key areas that need addressing. Irreversibility is also now considered.

The new author list has lots of changes from the AR4. A very quick analysis shows that less than 20% of the Coordinating Lead Authors or Lead Authors from AR4 are Coordinating Lead Authors or Lead Authors in AR5. Notable absences include Phil Jones, Keith Briffa and Michael Mann (although Mann was not an AR4 author either) – whether this is a consequence of “Climategate” is unknown but I expect it will make some people happy.

More nations are now represented in the list of Coordinating Lead Authors or Lead Authors (up to 45 from 34) but American authors now make up a slightly greater proportion (26% vs. 21%).

From this very quick look, it would seem difficult to criticise the AR5 IPCC for being the same old faces, so congratulations to them on that count.

Caveats: I’ve not looked at how these changes compare to the author-tunrover from the Third to the Fourth ARs and old Coordinating Lead Authors or Lead Authors could still turn up as Contributing Authors.

The number crunching for this post was done by Meghan Hughes. Thanks!

    From the various IPCC authors I’ve talked to, I’m impressed that anyone does more than one round… especially if they have to participate in the word-by-word crafting of the SPM.
