Judith Curry confuses laypeople about climate models

Judith Curry has written a report for the Global Warming Policy Foundation called Climate Models for the layman. As you can imagine, the key conclusions is that climate models are not fit for the purpose of justifying political policies to … Continue reading

Engineering the software for understanding climate change

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

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

Guest post: Some thoughts on Climate Modeling

This is guest post by Michael Tobis, partly motivated by some discussions we’ve had about modelling. In particular, the difference between modelling in the physical sciences, and modelling in other research areas. My personal – and not entirely ill-informed – … Continue reading

Models don’t over-estimate warming?

I thought I might write about the new paper by Jochem Marotzke and Piers Forster called Forcing, feedback and internal variability in global temperature trends. It’s already been discussed in a Carbon Brief post called claims that climate models overestimate … Continue reading

Nonlinear feedbacks

I’ve written a number of posts about the energy balance models (EBMs) used by Nic Lewis and thought I might write one more (sorry SB 🙂 ). In a previous post, Victor asked what I thought the reasons were for … Continue reading

What else can you do with a GCM?

Since I’m tired/bored of the climate “debate” I thought I might write a quick post about something that’s related to climate change, but probably not particularly controversial. I came across a paper recently by Shields et al. (2014) called Spectrum-driven … Continue reading
