“Climate Reality Check is a critically important report.  Yet again the Breakthrough team have forensically assessed the latest climate science from an outsiders perspective, and highlighted key risks which confront humanity.  Some may regard their conclusions as a worst case scenario. Unfortunately, over the  last three decades, bad-to-worst cases have often become climate reality — just think of the Australian bushfire inferno less than a year ago. So their conclusion — that “The short term is crucial; what we do now and before 2030 matters, not aspirations about 2050” — must be taken seriously.”

— Professor Hans Joachim Schellnhuber
Founder, Potsdam Institute for Climate Impact Research


“I fully support this excellent paper.  Of course scientific knowledge will never be perfect, but we already know enough for it to be crystal clear that we must now initiate emergency climate action.  The Cambridge Centre for Climate Repair is working to that end, and we look forward to co-operating with Breakthrough and like-minded organisations in Australia.”

Climate Reality Check

20 critical understandings, observations & insights


“Climate Reality Check is devastatingly accurate. After reading it, when the shock subsided, I felt enormous gratitude to the authors for giving us an explicit and unambiguous statement about the condition our planet is in. I would dearly wish every thinking person to read it, think some more, then do everything they possibly can to help us get through the titanic upheaval that lies ahead.”

— Professor Charlie Veron, PhD, DSc
Former chief scientist of the Australian Institute of Marine Science


“The Australian Breakthrough group focus relentlessly on interpreting the risk implications of climate change, risks that are badly under-estimated by governments, business and financiers.  Whilst I do not agree with all of their arguments, there is no doubt about their central conclusion, the urgency to reach net zero emissions long before 2050, ideally by 2030.”

— Professor Michael E. Mann
Distinguished Professor, Director, Earth System Science Center, The Pennsylvania State University


“Ten years ago, this Climate Reality Check report would have been seen as alarmist. The fact that it would now be seen as a reasonable statement of the current situation should be a wake up call for all the Nero’s watching as Rome burns. The Climate Reality Check brings together multiple lines of evidence that together point at a Climate Emergency. A significant part of an appropriate response to this emergency is to reach net zero emissions as soon as possible, not as soon as convenient”.

Director of the ARC Centre of Excellence for Climate Extremes, The University of New South Wales, Sydney
