Carbon Dioxide Removal (CDR) Modeling Experiments

CC-BY-4.0, 2020 Shannon A. Fiume

This project models highly speculative Carbon Dioxide Removal to understand its effects and speculate how much carbon may need to be removed to return to a carbon dioxide concentration of 280 ppm. The experiments are performed in MAGICC6.8 and have been run on pymagicc. The repo contains the scenario input files for MAGICC and a notebook that outlines the experiments and results.

The experiments are shown in ONCtests.ipynb which is a jupyter notebook that runs pymagicc, and requires windows or wine when run on a non-windows platform. To run these experiments, download wine, python, pip, pymagicc, this repo, and open the notebook in jupyter.

Install and run the workbook

Download/install wine

Next open a terminal, and add wine to the path.

Then run:

pip install -r requirements.txt
jupyter-notebook ONCtests.ipynb

Install for development

Open a terminal and do something like the following:

which wine
git clone https://github.com/hsbay/cdrmex
git clone https://github.com/openscm/pymagicc
cd pymagicc
make venv
./venv/bin/pip install --editable .
./venv/bin/pip install ipywidgets appmode
./venv/bin/pip install -r requirements.txt
jupyter nbextension enable --py --sys-prefix widgetsnbextension
jupyter nbextension     enable --py --sys-prefix appmode
jupyter serverextension enable --py --sys-prefix appmode
./venv/bin/jupyter-notebook ../cdrmex/ONCtests.ipynb

After the notebook is up, run all the cells, if they haven't already been populated.
