Carbon Dioxide Removal (CDR) Modeling Experiments

CC-BY-4.0, 2020-2024 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 300 ppm by mid-century and essentially 0ºC by 2100. 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.

For best-effort scientific findings from a citizen scientist, see my
preprint and AGU'23 poster.

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.
