Reconciling climate sensitivity estimates – part III, or IV?

I mentioned in a recent post that there was a new paper that claims to reconciles climate sensitivity estimates. The basic issue is that observationally-based climate sensitivity estimates have a range of about 1.5oC to about 3oC, while climate model … 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

2017: A year in review

I’ve now been writing this blog for almost 5 years and I still don’t quite know what I’m trying to achieve, if anything. Hopefully a blog that presents a reasonable representation of our current understanding of climate science, while also … Continue reading

More about Equilibrium Climate Sensitivity

It’s currently the AGU Fall Meeting and there was a session on Climate sensitivity and feedbacks. It included talks by Kate Marvel and Kyle Armour, and I noticed that the Convener, Andrew Dessler, had tweeted This leads to one of … Continue reading

Combining different ECS estimates

I wanted to briefly highlight a new paper by Nic Lewis and Peter Grünwald called [o]bjectively combining AR5 instrumental period and paleoclimate climate sensitivity evidence. You may want, however, to be cautious of the term objective. As the title indicates, … Continue reading

A bit more about clouds

A few years ago I posted a video by Andrew Dessler that was discussing whether or not Equilibrium Climate Sensitivity could be less than 3oC. The bottom line was that the best estimate for ECS is about 3oC. Given that … Continue reading

More time …. really?

A recent paper about [e]mission budgets and pathways consistent with limiting warming to 1.5 °C essentially argues that it is still possible to follow an emission pathway that will give us a good chance of keeping warming below 1.5oC. More specifically, … Continue reading

Climate sensitivity reconciled?

There’s a really interesting paper by Mark Richardson, Kevin Cowtan, Ed Hawkins, and Martin Stolpe called Reconciled climate response estimates from climate models and the energy budget of Earth. Ed already has post that explains it all very clearly, so … Continue reading

What a surprise …. not

To the surprise of no one, Nic Lewis has found many serious problems with the recently published Marvel et al. paper (also discussed here and here). Even less of a surprise is Andrew Montford lapping up Nic’s claims with glee. … Continue reading

Watt about Roger’s questions?

I haven’t done a Watt about post for quite some time, so thought I would repeat it just this once. Roger Pielke Sr has guest post on Watts Up With That claiming to present seven very inconvenient questions that Gavin … Continue reading
