Climate change: Are we up to the challenge? Graeme I Pearman Director, Graeme Pearman Consulting Pty Ltd Adjunct Senior Research Fellow, Monash University Board, The Climate Institute, START International Climate change: Are we up to the challenge? • What is the climate change issue? September 20, 2010 Aust. Inst. Physics/Roy. Aust. Chemical Inst. Climate Change: Spreading the GOOD News The climate change issue Aspirations Energy supply/demand Efficiency Energy demand GDP Choice of technology Climate system Climate impacts Climate change Emissions Human health The climate change issue Aspirations Energy supply/demand Efficiency Energy demand GDP Culture, education, advertising, promotions Climate impacts Climate change Emissions Choice of technology Perceptions, conscious or unconscious of: • Wellbeing • Success Climate system • Vested interests • Natural resources • Ignorance • Market failure Human health • Risk assessment • Beliefs • Ignorance • Sectoral interests What is possible? What we know and don’t know is based on: • Principles of physics and fluid dynamics – Greenhouse gases impact global temperature known for 120 years • Observed change - distant past – We can not take climate stability for granted • Observed change - recent past – Warming has occurred with associated changes to biology, water availability, etc. • Anticipated future climate change – Unless emissions are reduced, warming will continue • Anticipated impacts – On all sectors of the society, but unevenly spread • Uncertainty – Remains and this will always be so Key questions to be addressed • What is climate change? – The change to the long-term weather due to greenhouse gases • Has the Earth’ climate changed in the past? – Yes, “enormously” through geologic times • Has the climate changed recently? – Yes, the atmosphere and oceans have warned globally and in Australia • Are humans the cause? – Our use of energy is increasing greenhouse gases in the atmosphere, and this is very likely the reason for recent warming Key questions to be addressed • What will happen into the future? – Depends on how much more we emit these gases • What are the consequences? – It will have significant impact on society and the environment • How do we deal with the uncertainties of the science? – We weigh the probability of the scientific projections being correct against the impact if they are – But this challenges many who wish perfect anticipation of the future Global surface temperature change relative to 1951-1980 mean Hanson et al.

Climate change: Are we up to the challenge? • What is the climate change issue? • What is it about us that causes this issue? • What is it about us that makes it hard to respond? • Conclusions Messages about sustainability Solutions to the climate change issue depend on: • Acceptance that we will not know all that we would like to know before action is necessary – We have to manage the risk • We need to challenge the largely unconscious drivers of our behaviour, institutions and society – Commercialism – Advertising – Non-strategic social evolution Things to do • Understand your “energy” and “water” footprints –How much you use –From what activities –With what flexibility –It is empowering- you have personal options then • Set targets of reduction –Monitor power, gas and petroleum bills –Assess $ and carbon savings –Reward success •Your kids •Your employees –Be educated/equipped to make better purchases • Tell others –Especially local and regional Governments –Your teacher, parents, boss • Above all, examine what it is that is really important Climate change: A most challenging issue • Diabolical because it is: – – – – – Uncertain in its format and extent Insidious rather than (as yet) confrontational Long-term rather than immediate International as well as national Dangerous in the absence of effective mitigation • It results from the very way we are as individuals and the way our societies have evolved – Our aspirations and energy demands – Concepts of what represents ‘success’ and ‘happiness’ – Institutional frameworks that influence conformity and community-wide values • Solutions depend on changes that potentially threaten those aspirations, belief systems and attitudes
