An attempt to do a Bayesian estimate of climate sensitivity
Update (02/04/2019): I’ve updated this in a new post. The updated result suggests a slightly lower climate sensitivity and a narrower range. The main difference is – I think – how I was handling the forcing uncertainty. In this post, … Continue reading

New ocean heat content analysis
Update: (26/09/2019) This paper has now been retracted. The authors says Shortly after publication, arising from comments from Nicholas Lewis, we realized that our reported uncertainties were underestimated owing to our treatment of certain systematic errors as random errors. In … Continue reading

Assessing global warming
A couple of years ago I wrote a joint post with Roger Pielke Sr that discussed assessing anthropogenic global warming. The post basically used changes in ocean heat content to assess anthropogenic global warming. The basic idea (which is not … Continue reading
Full-depth OHC
Since my holiday is now over, I thought I might briefly comment on a recent paper by Cheng et al., called Observed and simulated full-depth ocean heat-content changes for 1970–2005. John Abraham, one of the authors, has already discussed it … Continue reading

World’s oceans
I’m travelling today, so have a bit of time to briefly comment on this recent paper by Glecker et al. which suggests that Industrial-era global ocean heat uptake doubles in recent decades. One of the key results – shown in … Continue reading
Assessing anthropogenic global warming
This post is really a joint post, written by myself and by Roger Pielke Sr. It’s partly a continuation of a post Roger wrote on Judith Curry’s blog, and partly a consequence of my attempt to answer one of Roger’s … Continue reading
The Oceans can save us!
Although I don’t really feel like explicitly debunking what I see on some “skeptic” sites (Sou does enough for all of us 🙂 ) I do sometimes, to my eternal regret, read them. I recently came across a standard argument … Continue reading
An OHC update
I thought I might briefly mention the recent paper on Quantifying underestimates of long-term upper-ocean warming, by Durack et al. (2014). The relevant result is stated in the abstract, which says Using satellite altimetry observations and a large suite of … Continue reading
We’ve all forgotten about the oceans!
I recently wrote a blog post about Roger Pielke Sr’s guest post on Climate etc. in which he was suggesting an alternative metric to assess global warming. Roger was essentially suggesting that we should be using the ocean heat content … Continue reading
Assessing global warming
I haven’t really tackled anything specifically physicsy for a while so I thought I might comment on a recent post on Judith Curry’s blog that was pointed out to me by Very Tall Guy. It’s a guest post by Roger … Continue reading
