This report examines the global response to climate change and considers how the world is heading toward reducing emissions of greenhouse gases and meeting the goal of avoiding the most damaging effects of climate change. It is clear that around the world most countries are now acting on climate change. In fact, some countries have been acting for more than 20 years. The Climate Commission set out the clear scientific evidence that humans are the main cause of climate change in The Critical Decade: Climate science, risks and responses. It pointed out how the risks from a changing climate multiply if emissions of greenhouse gases continue to grow beyond 2020. We are already seeing the social, economic and environmental impacts of a changing climate including rising sea levels and increasing frequency and intensity of extreme weather such as heat-waves and bushfires (IPCC, 2011).
