Reconciling climate sensitivity estimates – part III, or IV?

Posted on July 11, 2017 by

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 →

Prospects for narrowing ECS bounds

Posted on November 30, 2016 by

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

Posted on June 26, 2016 by

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

Posted on April 17, 2016 by

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 →
