Scientific American: Geoengineering May Be Our Best Chance to Save Sea Ice
„Is there a geoengineering technique that would cool the entire planet? Is there a way to cool only the Arctic in summer, to keep sea ice from disappearing?“

„But the implications of such grandiose engineering projects[nbsp]are far from clear. So, as well as considering the statutory regulation of geoengineering research,[nbsp]policymakers[nbsp]should think over the ethics of investing in such strategies — given their uncertainty, would the money be better spent elsewhere?„
„According to news accounts, the draft summary recognizes the possible necessity of CDR in the future, noting that if the world breaches the 2C threshold, governments will probably need to „deploy CDR technologies to an extent that net global carbon dioxide emissions become negative“ this century.“
Keith-Hamilton-debate as audio and transcript. „David Keith from Harvard University and Clive Hamilton of Charles Sturt University in Australia debate the case for each side with host Steve Curwood.“
Response to Ferraro, Angus J.; et al. (2014). „We did have a fall-back position, which was to counter the warming by geo-engineering—but now the leading technique for geo-engineering also looks like it will not work.“
„Some of the technologies cited in the latest draft report by United Nations climate experts face significant obstacles before they can be widely put in effect to limit the impact of climate change.“
„In other words, SRM may be one way in which global temperatures could be artificially stabilized. But a new study in the Journal of Geophysical Research: Atmospheres, finds that while SRM-style geoengineering may succeed in cooling the Earth, it would also disrupt precipitation patterns around the world.“
„Geoengineering may be necessary for 2C world, says IPCC draft“
