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

What does the Vostok ice core tell us?

Euan Mearns, who runs a blog called Energy Matters, had a post in 2014 about The Vostok ice core: Temperature CO2 and CH4. This post has apparently had 8000 reads, is probably one of the most read texts on the … 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

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

Planetary Energy Imbalance

I’m on a train heading to a meeting, and so, to move on from the whole Brexit saga, I thought I would briefly highlight this recent paper that provides an [Improved] estimate of Earth’s energy imbalance. It uses ocean heat … Continue reading

Time dependent feedbacks

There’s a very interesting new paper by Gregory and Andrews called Variation in climate sensitivity and feedback parameters during the historical period. The motivation seems to be to try and reconcile why estimates of the effective climate sensitivity using recent … Continue reading

ECS > 2K again

I’ve been away at a meeting where there talks from 9am till about 6pm and then various evening activities. I then came back to work and spent yesterday marking undergraduate research presentations. So, I haven’t had a chance to post … Continue reading
