Turkaly, Carolyn; et al. (2017): Establishing a Climate Engineering Research Clearinghouse

Turkaly, Carolyn; Nicholson, Simon; Livingston, David; Thompson, Michael (2017): Establishing a Climate Engineering Research Clearinghouse. Carnegie Endowment for International Peace; Forum for Climate Engineering Assessment. Washington, D.C.

"On July 18, 2017, the Forum for Climate Engineering Assessment and the Carnegie Endowment for International Peace convened a meeting of experts in CE science and governance, transparency, and information visualization to discuss designing, implementing, and maintaining a CE clearinghouse. A research registry, database, or clearinghouse is often cited as a necessary transparency mechanism in the governance of CE research. This workshop, building on a 2015 meeting on disclosure mechanisms for solar radiation management convened in Ottawa,1 such a clearinghouse from principle to practice."

Energy Post: The geo-engineering taboo

"A new book by David Hone, Chief Climate Change Adviser at Shell, takes the reader on a journey through the transition in the energy system that must be undertaken to address the climate change issue. The book, Putting the Genie Back: Solving the Climate and Energy Dilemma, deals with a wide range of topics, including carbon pricing, electric cars and solar power, and even ventures into areas such as the somewhat taboo subject of geo-engineering. What follows is an excerpt from the book where Hone discusses the geo-engineering solution."

Schrickel, Isabell; Engemann, Christoph (2017): Dealing with Climate Change. A Conversation with Paul N. Edwards and Oliver Geden

Schrickel, Isabell; Engemann, Christoph (2017): Dealing with Climate Change. A Conversation with Paul N. Edwards and Oliver Geden. In: Ber. Wissenschaftsgesch. 40 (2), S. 175–185. DOI: 10.1002/bewi.201701848

Discussion on climate policy, research and CE. "Paul N. Edwards is a historian of science and technology who has worked at the intersection of politics, computers and knowledge infrastructures. In his recent book, A Vast Machine (2010), he has described the emergence of the global knowledge infrastructures of climate science in the historical context. He is actively involved in the debates on the Anthropocene – as an educator as well as a writer. Oliver Geden has a background in anthropology and is head of the European Union research division of the German Institute for International and Security Affairs (Stiftung für Wissenschaft und Politik, SWP), one of Europe's largest foreign policy think tanks."

Brink: Time for a Global Discussion on Climate Geoengineering

By Janos Pasztor. "Imagine a scenario where, after insufficient action by world governments, global temperatures have continued to rise; impacts of climate change have become substantial and frequent; and the world heads to a warming of 3-4 degrees Celsius above preindustrial levels. As a result, a handful of small countries, or a group of large coastal cities whose survival is threatened with sea level rise, in alliance with a billionaire philanthropist, decide unilaterally to save the world by spraying chemicals into the stratosphere to begin cooling the Earth."

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."
