Overview: This publication from the Australian Academy of Science aims to address confusion created by contradictory information in the public domain. It sets out to explain the current situation in climate science, including where there is consensus in the scientific community and where uncertainties exist. The document is structured around nine questions:
- What is climate change?
- How has climate changed?
- Are human activities causing climate change?
- How do we expect climate to evolve in the future?
- How are extreme events changing?
- How are sea levels changing?
- What are the impacts of climate change?
- What are the uncertainties and their implications?
- What does science say about options to address climate change?
‘The science of climate change: Questions and answers’ was prepared by a working group of nine members co-chaired by Dr Ian Allison and Professor Mike Raupach FAA FTSE. The document was also reviewed by an oversight committee of eight members chaired by Professor John Zillman AO FAA FTSE. This publication is an update of the Academy’s 2010 booklet of the same name.
