3 AR6 Quantification
IPCC Sixth Assement Report (AR6)
3.1 Report quantification - version 1.0 manual count (work in progress)
Data, full stats, and methods.
A scoping literature review shows no comprehensive AR6 or IPCC Assement Reports quantification.
We believe what has been collected is the first attempt at such measurement.
An automated count will be carried out using TIB Grobi software https://projects.tib.eu/grobi in Q4 2025.
3.2 What is the AR6 report
AR6 is comprised of seven reports:
- the Synthesis Report (referred to as SYR)
- the 3 Working group reports (referred to as WGI, WGII, WGIII)
- the 3 Special reports (referred to as SR1.5, SRCCL, SROCC)
