A. Johnstone (UK socialist and activist) on system change ot avert climate genocide (2011): “Yet it [terracide] needn't be. An Australian engineering team called Beyond Zero Emissions has released its 5 year study that shows how Australia can have 100% renewable energy by 2020 using renewable technologies of wind power and concentrated solar thermal with molten salts energy storage for 24/7, baseload operation. Professor Mark Jacobson of Stanford University, California, and Mark A. Delucchi of University of California Davis have produced a plan for 100% renewable energy plan for the whole world by 2020. “James Hansen in answer to the question “Is there any real chance of averting the climate crisis?”, has stated: “Absolutely. It is possible – if we give politicians a cold, hard slap in the face. The fraudulence of the Copenhagen approach – 'goals' for emission reductions, 'offsets' that render ironclad goals almost meaningless, the ineffectual 'cap-and-trade' mechanism – must be exposed. We must rebel against such politics as usual.” Capitalism denies - or through resolute inaction effectively denies - the acute problem of man-made climate change. Capitalism – that brought us wars and holocausts – has been unable or unwilling to address man-made climate change and now threatens a climate genocide. It must be system change, not climate change” (A.
