An attempt to do a Bayesian estimate of climate sensitivity

Posted on March 25, 2019 by

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

Posted on November 3, 2018 by

Update: (26/09/2019) This paper has now been retracted.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 →

Lewis and Curry, again

Posted on April 27, 2018 by

I should probably say something about the new Lewis & Curry paper. It’s mostly an update to their earlier paper that I’ve discussed before. Bottom line; there are reasons to be cautious. The basic formalism is that one can use … Continue reading →

A bit more about committed warming

Posted on October 1, 2017 by

On a number of occasions I’ve pointed out that our warming committment is not actually the equilibrium temperature to our current atmospheric concentration because, if we halted all emissions, atmospheric CO2 would drop as the natural sinks took up more … Continue reading →

Beyond equilibrium climate sensitivity

Posted on September 7, 2017 by

Since I’ve written about climate sensitivity before, and since I have a few free moments, I thought I would briefly highlight a new paper by Knutti, Rugenstein, and Hegerl called Beyond Equilibrium Climate Sensitivity. It’s really a review of a … Continue reading →

Non-linear climate sensitivity

Posted on November 15, 2016 by

Rather strangely, the recent Science Advances paper Nonlinear climate sensitivity and its implications for future greenhouse warming, that’s been getting some attention recently, made it into our Journal Club today (and it had nothing to do with me). It’s, consequently, … Continue reading →

Full-depth OHC

Posted on July 28, 2016 by

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 →
