Climate modelling in Excel...

You can download the implementation of the FaIRv2.0 model in Excel described in this post here.

This is a brief post that introduces an Excel version of the FaIRv2.0 model¹ that I’ve created. I go through some of the key features, suggest some experiments that you can do, and provide recipes for how to carry out a few different types of analyses with the model.

How long left?

A recent CarbonBrief analysis estimated when two key global temperature targets (1.5 and 2.0 °C) would be exceeded using an ensemble of climate models from CMIP6. Inspired by this, I thought I’d try and carry out something similar, but using a large probabilistic simple climate model ensemble rather than the complex CMIP6 model ensemble in the original article.
