Another CMIP6 climate sensitivity constraint

I thought I would follow up yesterday’s post with one that highlights another paper that looks at CMIP6 climate sensitivity. It’s a paper by Femke Nijsse, and colleagues, and considers [a]n emergent constraint on Transient Climate Response from simulated historical … Continue reading

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Update: (26/09/2019) This paper has now been retracted.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

Lewis and Curry, again

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

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

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

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
