How much methane removal is required to avoid overshooting 1.5°C?
10.5281/zenodo.10601249.
Abstract
This repository reproduces the results from Smith & Mathison, submitted. Code is available from GitHub at https://github.com/chrisroadmap/methane-mitigation. The Zenodo version includes the results directory, which are datasets that are too large for GitHub.
Reproduction steps
Set up conda repository
This assumes that you are using anaconda and python. Currently, fair and fair-calibrate appear to be most stable with python versions 3.8, 3.9, 3.10 and 3.11. Others may work, but these ones are tested.
1. Create your environment:
$ conda env create -f environment.yml2. If you want to make nice version-control friendly notebooks, which will remove all output and data upon committing, run
$ nbstripout --install
Run and reproduce results
1. Fire up jupyter notebook
$ jupyter notebook
2. Inside notebook, navigate to notebooks directory. Run the notebooks in this order: - adaptive-removal-1.4.0.ipynb: this does the data crunching. It will likely take between 6 and 24 hours, depending on your machine. - zec-1.4.0.ipynb: calculate ZEC and carbon cycle metrics - analyse-1.4.0.ipynb: produce the results and plots reported in the paper
3. As a sensitivity case we run 10 MtCH4 removal steps (default 20); the results are almost identical but runtime is slower. These are in the files adaptive-removal-1.4.0-10Mt.ipynb and analyse-1.4.0-10Mt.ipynb.
