Technical Report

The Technical Report is intended to provide detailed information for researchers and decision makers.

It is a comprehensive report outlining the key climate change projection messages for Australia across a range of variables. The report underpins all information found in other products, including this website. It contains an extensive set of figures and descriptions on recent Australian climate trends, global climate change science, climate model evaluation processes, modelling methodologies and downscaling approaches. The report includes a chapter describing how to use climate change data in impact assessment and adaptation planning.

You can download the full report or individual chapters as PDF files.

Cluster Reports

Cluster Reports are intended to provide regional detail for planners and decision makers

The Cluster Reports, for eight regions of Australia , are to assist regional decision makers in understanding the important messages deduced from climate change projection modelling. The Cluster Reports present a range of emissions scenarios across multiple variables and years. They also include relevant sub-cluster level information in cases where distinct messages are evident in the projections.
