Garnaut climate change review: interim report

"Developments in mainstream scientific opinion on the relationship between emissions
accumulations and climate outcomes, and the Review’s own work on future “business as
usual” global emissions, suggest that the world is moving towards high risks of
dangerous climate change more rapidly than has generally been understood. This makes mitigation more urgent and more costly. At the same time, it makes the probable
effects of unmitigated climate change more costly, for Australia and for the world".
