Overview

The notebooks included in this repository implement the categorisation of scenarios by climate impact and generate figures, tables, summary statistics, and assessment indicators used in the IPCC Special Report on Global Warming of 1.5°C (SR15).

See assessment/README for an overview of notebooks and the cross-references to figures, tables and assessment in the SR15.

A rendered version of this repository and the notebooks are available at data.ene.iiasa.ac.at/sr15scenarioanalysis.

Data release notes

We are using this repository to track data issues identified in the scenario ensemble. Please check the related issues labeled 'iamc15 data issue' and the data release notes in this repository.

Scenario ensemble download

The scenario ensemble used for this assessment and the metadata table of scenario categorisation and quantitative indicators are available for download via the IAMC 1.5°C Scenario Explorer.

The scenario data is released under a custom license. If appropriate reference is made to the data source, it is permitted to use the data for scientific research and science communication. However, redistribution of substantial portions of the data is restricted.

Please read the guidelines and legal code at data.ene.iiasa.ac.at/iamc-1.5c-explorer/#/license before redistributing this data or adapted material.

When using the scenario data for any analysis, figures or tables, please clearly state the release version of the scenario ensemble.
