IASS Blog: Stop shaming geo-engineering researchers!

"Environmentalists are often critical of technological fixes problems caused by technology. But when it comes to geo-engineering, a clear distinction needs to be made between the message and the messenger."

Honegger, Matthias; et al. (2017): Climate change, negative emissions and solar radiation management: It is time for an open societal conversation

Honegger, Matthias; Münch, Steffen; Hirsch, Annette; Beuttler, Christoph; Peter, Thomas; Burns, Wil et al. (2017): Climate change, negative emissions and solar radiation management: It is time for an open societal conversation. Risk-Dialogue Foundation St.Gallen; Swiss Federal Office for the Environment (White Paper).

"An open societal conversation needs to address the emerging topic of climate engineering. The possibility of novel approaches to limit climate risk is increasingly discussed among researchers and carries important social, environmental, and ethical implications and risks. Tough questions on governance, protection against misuse, costs, benefits and risks of both climate change and climate engineering demand an open conversation in order to build a robust basis for reasoned and democratic decisions in Switzerland and indeed the whole world."

Lenferna, Alex; et al. (2017): Relevant Climate Response Tests for Stratospheric Aerosol Injection. A Combined Ethical and Scientific Analysis

Lenferna, Alex; Russotto, Rick; Tan, Amanda; Gardiner, Stephen; Ackerman, Thomas (2017): Relevant Climate Response Tests for Stratospheric Aerosol Injection. A Combined Ethical and Scientific Analysis. In Earth's Future. DOI: 10.1002/2016EF000504.

"In this paper, we focus on stratospheric sulfate injection as a geoengineering scheme, and provide a combined scientific and ethical analysis of climate response tests, which are a subset of outdoor tests that would seek to impose detectable and attributable changes to climate variables on global or regional scales. We assess the current state of scientific understanding on the plausibility and scalability of climate response tests. Then we delineate a minimal baseline against which to consider whether certain climate response tests would be relevant for a deployment scenario. Our analysis shows that some climate response tests, such as those attempting to detect changes in regional climate impacts, may not be deployable in time periods relevant to realistic geoengineering scenarios. This might pose significant challenges for justifying SSI deployment overall."

Project: NERC with £8.6 million UK research programme on greenhouse gas removal

"To help answer these questions, the £8·6 million Greenhouse Gas Removal Research Programme will evaluate the potential and wider implications of a variety of options. For example, researchers will investigate the potential for increasing carbon storage in agricultural soil and forests, and new ways to remove methane gas from the air on a local scale. Other researchers will look into using waste materials from mining as a greenhouse gas removal technique, and explore how bioenergy crops could be used in power stations in combination with carbon capture and storage methods. Recognising that the UK alone cannot solve these problems, the research will address the political, socio-economic, technological and environmental issues concerning the potential for greenhouse gas removal on a global scale."

Harvard Crimson: Harvard Researchers Launch Solar Geoengineering Moonshot

"Launched this weekend, Harvard’s Solar Geoengineering Research Program will investigate the safety of geoengineering as well as its environmental and political implications. Scientists specifically look into a technique of injecting specific particles into Earth’s upper atmosphere to create a barrier that reflects more sunlight away from the atmosphere."

MIT Technology Review: The Growing Case for Geoengineering

"As climate change accelerates, a handful of scientists are eager to move ahead with experiments testing ways to counteract warming artificially. Their reasoning: we just might get desperate enough to use this technology one day."

BBC: Do We Need A Plan B For Climate Change?

Fuss, Sabine; et al. (2016): Research priorities for negative emissions

Fuss, Sabine; Jones, Chris D.; Kraxner, Florian; Peters, Glen P.; Smith, P.; Tavoni, Massimo et al. (2016): Research priorities for negative emissions. In Environ. Res. Lett. 11 (11), p. 115007. DOI: 10.1088/1748-9326/11/11/115007.

"While there are few pathways to 2 °C that do not rely on negative emissions, 1.5 °C scenarios are barely conceivable without them. Building on previous assessments of NETs, we identify some urgent research needs to provide a more complete picture for reaching ambitious climate targets, and the role that NETs can play in reaching them."
