IPCC AR5 WG2 report – advance briefing Intergovernmental Panel on Climate Change (IPCC) Fifth Assessment, Working Group 3 report Questions and answers in advance of publication

Currently the political will to make these changes, for example reducing fossil fuel use or reducing inequalities between and within countries, is sorely lacking. Because of current and past failures to reduce carbon pollution it is not surprising that the IPCC has investigated geoengineering options. However, by doing so it potentially normalises these approaches alongside energy efficiency, renewables, etc. The risks of particularly solar radiation management are very high and this will need to be made clear. *What are others likely to say?* It is likely that climate deniers will identify the high costs of mitigation whilst ignoring the considerable benefits which outweigh the costs. It is also possible that right-wing think tanks and the media focus on the potential for geoengineering as a potentially low cost response to climate change, particularly regarding the extremely risky strategy of injection of aerosols into the stratosphere as a form of solar radiation management. Friends of the Earth is opposed to the deployment of solar radiation management. There is also the danger that some commentators also reject all negative emissions technologies in addition to rejecting solar radiation management. This is simplistic and could create opposition to development of necessary technologies to remove carbon pollution from the atmosphere (e.g. air capture of carbon utilising carbon capture and storage). -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
