On the meaning of independence in climate science

At long last jules and I have managed to submit the written version of a talk that I have given (bits of) no fewer than four times over the last few years (at NCAR, UKMO/HC, Schloss Ringberg and EGU). It had to get re-written several times and sit at the back of my mind on…

Oh Vienna redux

It’s April, so it must be EGU time again! No Vienna marathon this time – the race was the same date as Manchester this year, a week too early for our trip – so we went purely for the science. Well, the science and the schnitzel. The plan was to go over on the Friday…

Could the Pliocene constrain the Equilibrium Climate Sensitivity?

The long-awaited prequel to “Can the Last Glacial Maximum constrain climate sensitivity?” is now up on CPD and open for comment. This latest episode is set back in the mid-Pliocene warm period 3-3.3Ma BP (MPWP, sometimes also called mid-Piacenzian by people who care deeply about the conventions for paleoclimate nomenclature). The particular reason for looking…

TANSTAAFL

Otherwise known as, there ain’t no such thing as a free lunch. At least, there isn’t any longer in the Climate Division at NCAR. It feels like a long time ago that we last dropped in to give seminars at NCAR. Well, perhaps that’s not so surprising as it was during our previous careers 🙂…

Evaluation of CMIP5 palaeo-simulations to improve climate projections

Our latest paper has just appeared in Nature Climate Change: “Evaluation of CMIP5 palaeo-simulations to improve climate projections”. It was mainly the brainchild of Sandy Harrison, intended as a response/update to the “preview” paper “Evaluation of climate models using palaeoclimatic data” which promised that the PMIP component of CMIP5 would provide assessments of model performance,…

The EGU review 2015

If it’s April, it must be Austria. So far, our plan to travel less now we are back in the UK seems to be being mostly honoured in the breach. To be fair, we are travelling fewer miles and suffering less jet lag, and both these factors probably help to explain why we are still…

Climate sensitivity workshop at Schloss Ringberg

Last year jules went to Schloss Ringberg in Bavaria, for a workshop on cloud feedback and sensitivity “under the auspices of the World Climate Research Programmes (WCRP) Grand Science Challenge on Clouds, Circulation and Climate Sensitivity and with the support of the Max Planck Institute for Meteorology in Hamburg, Germany.” (oh, the report on that…
