Climate model tuning

Posted on September 5, 2017 by

I wrote a post about model tuning that discussed a paper that argued for more transparency in how climate models are tuned. Gavin Schmidt, and colleagues, have now published a paper that discusses the Practice and philosophy of climate model … Continue reading →

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 →

Engineering the software for understanding climate change

Posted on September 15, 2016 by

Since Judith Curry has a guest post about global climate models and the laws of physics, I thought it would be worth posting this recently released video of a talk about climate modelling (see below). It’s by Steve Easterbrook, who … Continue reading →
