The report, entitled Climate Change 2014: Mitigation of Climate Change, is the third of three Working Group reports, which, along with a Synthesis Report due in October 2014, constitute the IPCC’s Fifth Assessment Report on climate change. “Climate policies in line with the two degrees Celsius goal need to aim for substantial emission reductions,” Edenhofer said. “There is a clear message from science: To avoid dangerous interference with the climate system, we need to move away from business as usual.” Scenarios show that to have a likely chance of limiting the increase in global mean temperature to two degrees Celsius, means lowering global greenhouse gas emissions by 40 to 70 percent compared with 2010 by mid-century, and to near-zero by the end of this century. Ambitious mitigation may even require removing carbon dioxide from the atmosphere. Scientific literature confirms that even less ambitious temperature goals would still require similar emissions reductions. For the report, about 1200 scenarios from scientific literature have been analyzed. These scenarios were generated by 31 modelling teams around the world to explore the economic, technological and institutional prerequisites and implications of mitigation pathways with different degrees of ambition. ipcc.ch/pdf/ar5/pr_wg3/20140413_pr_pc_wg3_en.pdf bit.ly/Q31rgz
