Machine unlearning

Someone sent me a paper by John Abbot and Jennifer Marohasy called the application of machine learning for evaluating anthropogenic versus natural climate change. Their conclusion is that most of the observed warming could be natural and that the Equilibrium … Continue reading

Reconciling ECS estimates – again

I’m heading home after giving a public talk, and have a bit of time to write about the recent Armour paper Projection and Prediction: Climate Sensitivity on the rise. It’s basically another attempt to reconcile energy balance estimates for climate … Continue reading

Matt Ridley responds to Tim Palmer

I came across a response, by Matt Ridley, to Tim Palmer’s talk. I’ve posted Matt Ridley’s response below. One interesting aspect of his response is that it is written as if he is someone with the expertise to actually debate … Continue reading

Catastrophe, hoax, or just “Lukewarm”?

I thought I would post this video of a talk given by Tim Palmer. The basic message is that climate change is neither a hoax, going to be catastrophic, or going to be benign (Lukewarm). What climate science can (and … Continue reading

Not even giving physicists a bad name!

When I’m trying to have a bit of a dig at physicists (of which I’m one) who think they somehow know better than climate scientists, I’ll post the cartoon on the right. When I came across this interview with William … Continue reading

Prospects for narrowing ECS bounds

I was just going to briefly mention a new paper by Stevens, Sherwood, Bony and Webb in which they present [p]rospects for narrowing bounds on Earth’s equilibrium climate sensitivity. The basic argument is similar to what has – at times … 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

Model tuning

Came across a very interesting paper on the art and science of climate model tuning. Based on the comments here, it appears that some are interpreting this as confirming their claims that climate models are tuned to give preferred results. … 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

Climate Sensitivity on the Rise

There’s a Nature news & views article by Kyle Armour called Projection and prediction: Climate sensitivity on the rise. It discusses various analyses that indicate that simple energy balance methods tend to under-estimate climate sensitivity. Normally, I would write a … Continue reading
