This application is written in Python, with the help of the ReportLab library (the web part is powered by the flask framework). The code is open-source and is available here: framagit.org. The ability of this application to reproduce several figures published by the IPCC was carefully tested (however, the IPCC bears no responsibility for this software).
We are sorry to hear that you have encountered a problem. We will do everything we can to help. Please have a look at 'It did not work! Why?' in the tutorial. Do not hesitate to provide feedback.
The 'ember drawing' code is available as a python package which can be accessed from code written in python or R. The package and some examples are available from the standard python package index: PyPI - EmberMaker.
Although the web application and layout details were improved over time, there is no change affecting the translation of the risk levels provided as input to colours in the burning embers. The changes are recorded on framagit.org (see Changelog). A short summary is provided below (from recent to old).
When an update is planned, it might be announced on climrisk.org.
The update provides support for complex descriptions of transitions, which may involve one or both of the following:
In addition, the update simplifies the documentation by referring to the former "basic (file) format"
as the standard format. The former "full-flex" is kept for legacy file(s).
(version 1.7.1)
Allowed 'overlapping transitions', i.e. embers with 'uncertainty ranges' that
span across each other (e.g. it might be that risk is above or below 'high' at a given level).
Optional secondary axis (on the right, typically with a different scale), along with other new layout
options.
(version 1.6)
An optional median, or 'midpoint' between the start and end of each transition, is added in the 'Basic format'.
File format download options (PDF/PNG/JPEG) are added. All parameters are documented in a way
that is fully consistent with how they work (the same file provides online documentation and default
values).
(version 1.4)
This software was created by Philippe Marbaix at the end of 2019
(based on an earlier 'AR5-related' back-of-the-envelope version).
The first objective was to produce figure 3 of Zommers et al. (2020;
Burning Embers: Towards more transparent and robust climate change risk assessments.
Nature Reviews Earth & Environment. doi.org/10/gg985p).
Help is welcome to further improve the application. All contributions will be recognised :-). For more information, please e-mail philippe.marbaix@uclouvain.be.
