Blueskies tour of the USA

The possibility of visiting NCAR has been at the back of our minds for some time, so when the rare honour of invitations to speak at the AGU Fall Meeting in San Francisco plopped into both of our inboxes around June, we swung into action. A couple of months at NCAR rounded off with an…

Fame at last

This is…..big: And impeccably sourced 🙂 It’s not beyond criticism, actually – the timeline doesn’t resolve possible rapid changes in temperature, so the comparison of smoothed paleo reconstruction with modern observations could be considered a bit misleading (see tweets here for example). But this is a relatively minor quibble on what is really a very…

Assessing Paleoclimate Uncertainty

This was the title of a recent workshop held by the Past Earth Network (PEN) in Cambridge. PEN is one of 4 EPSRC-funded networks aiming to bring together mathematicians/statisticians and environmental scientists to help address problems in environmental change. While I wasn’t part of the PEN bid, I am acting as one of the co-leaders…

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…

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,…

Ten years of GENIE

British trains may be slow and prone to delay, but they are the main reason that British people are so ingenious. Harry Potter was famously dreamed up by JK Rowling on a train. And similarly, it was on a train that the idea of the earth system model we now called GENIE came into the  mind…

Blue skies at the UKMO Hadley Centre

I’ve just had a very enjoyable visit to the UKMO Hadley Centre, courtesy of Richard Betts. My talk was similar to the one I recently gave in Japan, which had been a bit clunky and unrehearsed in parts, so in the intervening weeks I revised it a bit which I think/hope made it a bit…

From the sublime to the ridiculous…and back again

Just had two weeks in Japan, mostly visiting our friends and colleagues in AORI and NIES. These institutes are both some way outside Tokyo but on the same train line out of Tokyo, so we stayed in Asakusa, close by the famous Senso-ji temple and very convenient for seeing various other friends and enjoying all…

The future of climate science

I recently had the pleasure of a trip to Brussels, courtesy of this workshop, organised by Michel Crucifix, Valerio Lucarini and StĂ©phane Vannitsem. Titled “Advances in Climate Theory”, it was a chance to discuss ideas related to…advances in climate theory, surprisingly enough. In practice, that included lots about the dynamics of the wiggles that are…
