Missing and underestimated feedbacks in the CMIP5 climate models used for the IPCC carbon budget

25th November 2013: Note for the Parliamentary Office of Science and Technology listing papers on missing or underestimated feedbacks in the CMIP5 climate models used to calculate the carbon budget in the recent IPCC report (AR5).

The papers on missing/underestimated feedbacks.

Postscript 26th November 2013

I am adding this postscript after some thought. Nearly all of the items in the list above reference papers that have been peer reviewed. I think there are occasions when the usually valuable demands of peer review exclude the less knowable and the very recent so there are occasions when points, which are important cannot easily be found in the peer reviewed literature.

Last hours

One feed back mentioned above that I would like to draw attention to concerns dissociating methane hydrates. Thank you for passing on my previous concerns to get an official response to the Last Hours video. This video concerning the longer term should be considered by POST as well.

Neven’s Sea Ice Blog

A good place to find up to the hour information can often be found on Neven’s Sea Ice Blog. Yesterday a new topic was started And the wind cries methane. POST should look at this and read the comments. The piece by Neven ends “Remember, you can track methane yourself on MethaneTracker.org.”
Looking yourself” is somewhat faster than peer review although not as reliable. (cf. Heisenberg)
