climate-assessment - Assessing the climate outcomes of future emissions scenarios

.. image:: https://zenodo.org/badge/501176611.svg :target: https://zenodo.org/badge/latestdoi/501176611

Please note that climate-assessment is still in early developmental stages, thus all interfaces are subject to change.

The package climate-assessment provides the possibility to reproduce the climate variable data for the working group III (WGIII or WG3) contribution to the IPCC Sixth Assessment (AR6) report, using climate emulators that were used in the working group I (WGI or WG1) contribution to AR6. It also allows for assessing new emissions pathways in a way that is fully consistent with AR6.

Installation

Note: the package's requirements are currently extremely strict. This is done to make it more likely that installation will result in a valid environment. If you want a fully specified environment, please use the poetry.lock or requirements.txt file provided in this repository. We hope to make the package more libary-like, with looser requirements, in future.

Using pip

`pip`_ is Python's default package management system.

.. attention:: Due to the better dependency resolution installing with ``pip>=22`` is recommended.

If you install Anaconda, then ``pip`` is also usable.
``pip`` can also be used when Python is installed directly, *without* using Anaconda.

1. Ensure ``pip`` is installed—with Anaconda, or according to the pip documentation.

2. Open a command prompt and run::

    $ pip install climate-assessment

From source

(Optional) If you intend to contribute changes to climate-assessment, installing directly from source <https://github.com/iiasa/climate-assessment>_ is the way to go.

Detailed instructions on how to do this can be found in the documentation under https://climate-assessment.readthedocs.io/en/latest/install.html.

Development

Raising an issue

If you have a suggestion for development, or find a bug, please report this under: https://github.com/iiasa/climate-assessment/issues.

Running the tests

The tests can be run with pytest. On a Linux system, you should run something like MAGICC_PROBABILISTIC_FILE=path/to/probabilistic-file pytest tests. Note that for the tests to work properly, you must set up your .env file (see "Environment" section above). On Windows, the environment variables (like MAGICC_PROBABILISTIC_FILE=path/to/probabilistic-file) should be set system-wide, and the command reads pytest tests.

Formatting code

Before committing or merging code, the following lines should be run to ensure that the formatting is consistent with what is expected by the Continuous Integration setup (for users with ``make`` installed, ``make checks`` will run these for you):

.. code:: bash

    black src scripts tests setup.py
    isort src scripts tests setup.py
    flake8 src scripts tests setup.py
