In Hot Water – Preparing for Climate Change Not to decide to win is to decide to fail! Greg Bourne, CEO WWF-Australia gbourne@wwf.org.au 21st April 2008

Based on the premise of stabilisation at ≤2˚C, optimism! A crisis period before a New Dynamic Equilibrium or Climate Runaway?

Not to decide to win..is to decide to fail! BAU defaults to societal, economic and environmental breakdown. A severe procrastination penalty But with Runaway Climate Change Societal, economic and environmental breakdown At least - 20% GDP loss New Sustainability Paradigm -1 to 2% GDP loss But possibly a gain in world GDP Keep on as Business As Usual (BAU) Work for Global Climate Treaty to stay below a 2 o C rise Deliberately IGNORE the climate challenge and try to “ACHIEVE ADVANTAGE” in a breakdown world

A Common Goal for Climate and Energy Policy Meet projected global growth in demand Avoid dangerous impacts of climate change Use only socially and environmentally benign energy sources
8
Six Solutions 1.Breaking the Link between Energy Services and Primary Energy Production 2.Stopping Forest Loss 3.Concurrent growth of Low-Emissions Technologies 4.Developing Flexible Fuels, Energy Storage and New Infrastructure 5.Displacing High-Carbon Coal with Low-Carbon Gas 6.Carbon Capture and Storage
9
Conclusions The report's conclusion is that the technologies and sustainable energy resources known or available today are sufficient to meet this challenge, and there is still sufficient time to build up and deploy them, but only if the necessary decisions are made in the next two years. Yet it is clear that the economic policies and governmental interventions needed to propel this transition are not now in place, or even in prospect in most cases. This is a matter to which the world needs to give urgent attention.
10
Three Imperatives 1.Urgency. Delays will make the transition to a low-carbon economy increasingly expensive and difficult, with much greater the risks of failure. The case for early, decisive action is overwhelming. 2.A global effort. Every country has a role to play, in response to the scale and the type of challenges arising in its territory. 3.Leadership. Action is needed by governments of the world to agree targets, to collaborate in effective strategies, and to influence and co-ordinate the investment of the many trillions of dollars which will be spent on energy developments in the coming decades in any event, so that future needs are met safely and sustainably.
