Welcome to the Climate Knowledge Graph

What is the Climate Knowledge Graph CKG

Logo

Climate Knowledge Graph is an R&D project with the goal of making climate change knowledge held in the IPCC Sixth Assessment Report more accessible using open science methods and FAIR data principles. At the core of the project is the creation of a knowledge graph which will support search and publishing, data analysis, and AI LLM use. The aim of the project is to service expert and citizen science communities, support multilingualism, and enable global access.

What is the IPCC

Logo

The IPCC provides regular assessments of the scientific basis of climate change, its impacts and future risks, and options for adaptation and mitigation.

Created in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP), the objective of the IPCC is to provide governments at all levels with scientific information that they can use to develop climate policies. IPCC reports are also a key input into international climate change negotiations. The IPCC is an organization of governments that are members of the United Nations or WMO.

IPCC reports

The IPCC prepares comprehensive Assessment Reports about the state of scientific, technical and socio-economic knowledge on climate change, its impacts and future risks, and options for reducing the rate at which climate change is taking place. The IPCC also produces Special Reports on specific topics agreed by its member governments, as well as Methodology Reports that provide practical guidelines for the preparation of greenhouse gas inventories. The Synthesis Report integrates the Assessment Report and any Special Reports prepared during an assessment cycle. A report consists of a number of chapters. It may also include a Technical Summary, prepared by the authors. Assessment Reports, Special Reports and the Synthesis Report include a Summary for Policymakers that is prepared by the authors and approved line by line by a Plenary Session of the IPCC with the delegates in dialogue with the authors.

IPCC assessment cycles

Comprehensive scientific assessment reports are published every 5 to 7 years. The IPCC is currently in its seventh assessment cycle.

Assessment cycle 6

IPCC Sixth Assessment Report (AR6)

The Sixth Assessment Report (AR6) comprises three Working Group contributions: Working Group I (the physical science basis), Working Group II (impacts, adaptation and vulnerability) and Working Group III (mitigation) and a Synthesis Report.

The Synthesis Report integrates the three Working Group reports as well as the findings from the three cross-Working Group Special Reports prepared during this assessment cycle: Special Report on Global Warming of 1.5ºC (SR15, October 2018), Special Report on Climate Change and Land (SRCCL, August 2019) and Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC, September 2019).

During the AR6 cycle the IPCC also updated its methodologies with the 2019 Refinement to the 2006 Guidelines on National Greenhouse Gas Inventories (May 2019).
