That new ocean heat content estimate

From Resplandy et al (conveniently already up on sci-hub): Our result — which relies on high-precision O2 measurements dating back to 1991 — suggests that ocean warming is at the high end of previous estimates, with implications for policy- relevant measurements of the Earth response to climate change, such as climate sensitivity to greenhouse gases…

Cox et al part 3

As promised some more on this. The first thing I thought, on seeing this paper – a feeling that others apparently shared – was, why had no-one else already thought of this? Had we all just behaved like the fabled economist who, when their companion points out a £10 note lying on the pavement, ignores it,…

The AGU review 2016

We’d rather enjoyed our last trip to the AGU and had always hoped to go back some time but it’s a long and expensive trip from the UK especially without having access to JAMSTEC’s generous travel budget. Back in February, PEN had decided to propose a session at the AGU this year, and there was…

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…
