# IPCC AR6 WGI - Chapter 11 Figures

[![DOI](https://zenodo.org/badge/DOI/10.5281/zenodo.7692016.svg)](https://doi.org/10.5281/zenodo.7692016)

This repository contains data analysis scripts and visualization of many figures of
Chapter 11 of the Sixth Assessment Report (AR6) of Working Group 1 (WGI) of the Intergovernmental Panel on
Climate Change (IPCC). It also includes parts of two figures in the Summary for Policymakers
(SPM), data preparation for one figure of Chapter 12, and of Figure SPM.2 of AR6 Synthesis Report (SYR).

## Figures

The following table shows which figures/ panels for the WGI _SPM_, _Chapter 11_ and _Chapter 12_ in the IPCC AR6 report were created from this repository. It also shows which part (data analysis and visualization) is actually done in the repository.

## Tables

The following shows which tables in Chapter 11 were created from this repository.

| Table    | Notebook | Data Source |
| -------- | -------- | ----------- |
| Table 11.SM.1   | [Table_11.SM.1_GSAT_anom](code/Table_11.SM.1_GSAT_anom.ipynb) | CMIP5 & CMIP6 |
| Table 11.SM.2-8 | [Table_11.SM_cmip_indices_regional](code/Table_11.SM_cmip_indices_regional.ipynb) | CMIP6 |

## Associated data repositories

There are three external data repositories associated with Chapter 11, which provide additional data and data used in the chapter in a computer accessible form.

### Global mean temperature anomalies for CMIP5 and CMIP6

The [cmip_temperatures](https://github.com/mathause/cmip_temperatures) repository provides mean temperature anomalies for different time periods for CMIP5 and CMIP6. It contains the same info as Table 11.SM.1. Note that these temperature anomalies are unassessed.

### Global warming levels for CMIP5 and CMIP6

The [cmip_warming_levels](https://github.com/mathause/cmip_warming_levels) repository documents the year when a certain global warming level was reached in CMIP5 and CMIP6 data. There is no associated table in the IPCC report.

### Multi-model-median regional means at warming levels for selected indices (CMIP6)

The [cmip_indices_regional](https://github.com/mathause/cmip_indices_regional) repository documents multi-model-median regional means at warming levels for selected indices (CMIP6) & contains the same info as Table 11.SM.2 through Table 11.SM.8.

## Regional Factsheets

The map insets for IPCC AR6 WGI [regional fact sheets](https://www.ipcc.ch/report/ar6/wg1/resources/factsheets/) were created in the [RegionalFactSheetsMaps](code/RegionalFactSheetsMaps.ipynb) notebook. These maps were used for the following fact sheets: Introduction, Africa, Asia, Australasia, Central and South America, Europe, North and Central America, and Ocean.

## Data

This repository is provided _without_ data. The data volume (approximately 1 TB) prohibits an efficient distribution. In addition not all data is in the public domain.

There are several ways to obtain some or all the data
- The data can be provided upon reasonable request (either the whole data folder or parts).
- Some of the final data (i.e. exactly what is shown in the figure) is available from [CEDA](https://catalogue.ceda.ac.uk), (e.g. the data for [Figure SPM 5](https://catalogue.ceda.ac.uk/uuid/2787230b963942009e452255a3880609)).
- Some datasets are publicly available, e.g. [HadEX3](https://www.metoffice.gov.uk/hadobs/hadex3/).
