This site hosts tools to create or view synthetic illustrations of climate change risks:

Climate Risks Embers Explorer ▶ Start here

"Burning embers" are an illustration of how climate change risks and impacts on humans and ecosystems increase with global warming. The aim of this app is to present burning ember diagrams from all IPCC reports so far (until AR6 included) in an homogenous and accessible way, with a view to link the diagrams with information describing what they represent.

The current version is 1.4.0: climrisk.org/cree. It is multilingual, supporting English, French, Dutch and Spanish (more languages may come if this proves useful). All generated figures can be downloaded in a variety of formats, and there is an option to show IPCC AR6 climate projections 'on top' of risk levels. Some may like the new 'dark' mode - although it may make your blood run cold.
Help with the translations (as well as further ember descriptions) would be most welcome!

EmberFactory ▶ Start here

The purpose of this application is to (re)produce burning ember diagrams of the style used in IPCC reports. The Ember Factory takes standardised Excel sheets describing color transitions as input. It produces quality figures in PDF format, editable with vector-drawing software if needed. [More...]

The current version is 2.1.0: climrisk.org/emberfactory
In the unlikely event of problems with the current version, you may try a previous one (1.6): climrisk.org/emberfactory-old.
This app was updated on 3 August 2024. Improvements are listed here. When there are known issues, they are listed here.

Ember Elicitation Desk (beta) ▶ Start here

The Ember Elicitation Desk is a tool to facilitate structured expert elicitation to illustrate climate change risks through "burning embers" diagrams. This version is still a pre-release (beta), but it reproduces a diagram from a past expert elicitation process and we hope that it is useful in its current form. [More...]

The current version is 0.5 (April 2024): climrisk.org/emberelicitation
An entirely new version is in development. News expected in the last months of 2025. Feedback would be very appreciated and could help guide future development

Maintenance

No major server update is planned in the near term (July 2025).

EmberMaker library

The "ember drawing" part of the EmberFactory is now available as a separate library/API: EmberMaker, available as python package on PyPI with examples including how it can be used within R provided on FramaGit. Version 2.2 is planned for the summer of 2025. It will facilitate translations and the publications on websites in 'dark mode'.
