Forum for Climate Enigneering Assessment: When essential research might be a bad thing. The carbon removal research dilemma. (Blogpost)

"The UK recently adopted a legislative 2050 target for ‘net-zero’ climate-changing emissions. Other countries are also moving towards similar goals. Such targets are hugely welcome in the face of growing climate change impacts. Yet delivering ‘net-zero’ depends not only on accelerated mitigation, but also critically on the development and deployment of carbon removal techniques. This creates something of a dilemma."

C2G2: Should solar geoengineering research proceed?

"While solar geoengineering could limit some harmful climate impacts, these approaches could also have adverse impacts and would not address the root cause of climate change: rising emissions of heat-trapping gases from burning fossil fuels – or some of the resulting impacts, such as ocean acidification. We also know very little about how it could impact regional weather patterns, global politics, and efforts to curb global warming emissions."

Harvard's Solar Geoengineering Research Program: Might research on solar geoengineering resemble its broader “free-driver” dynamics?

"It’s called “re-search” for a reason. You search, you search, and you search again. It also means that researchers will naturally tackle the low-hanging fruits first. Unearthing the harder bits just takes time. That’s the natural flow of things, and solar geoengineering research is unlikely to be different."

Axios: We asked five experts about engineering the climate

"In the face of rising global temperatures, deploying technologies to change Earth's climate has gone from thought experiment to reality. We already capture carbon and store it underground. Now some researchers are suggesting we should spray the clouds with particles to reflect sunlight, fertilize the oceans to promote carbon-absorbing plankton growth, or build a gigantic shade that orbits Earth and opens as needed to shield the planet from the sun. Welcome to the Anthropocene — the era of humans engineering the world in unprecedented ways."

Kreuter, Judith (2018): Climate engineering & political decision-making. The polarity in academic debate

Kreuter, Judith (2018): Climate engineering & political decision-making. The polarity in academic debate. Innovations in Climate Governance (INOGROV Policy Brief, 4).

"This INOGOV policy brief analyses the importance of polarity in academic debate surrounding climate engineering. It discusses the fact that while climate engineering approaches cannot yet be considered ‘physically tangible technological objects’ because they have not been implemented on a large scale; there is currently a unique opportunity to actively and critically shape the way in which we consider these approaches in the political debate."

Sugiyama, Masahiro; et al. (2017): Next steps in geoengineering scenario research. Limited deployment scenarios and beyond

Sugiyama, Masahiro; Arino, Yosuke; Kosugi, Takanobu; Kurosawa, Atsushi; Watanabe, Shingo (2017): Next steps in geoengineering scenario research. Limited deployment scenarios and beyond. In Climate Policy 18 (6), pp. 681–689. DOI: 10.1080/14693062.2017.1323721.

" In light of concerns over risks, a newer set of scenarios is desirable, which represents both uncertainties and social choices more fully. Borrowing and extending lessons from recent literature on the new community climate scenario process, we envision a possible scenario-building process that combines interdisciplinary scholarship with the involvement of stakeholders and citizens. The resultant scenarios would better characterize uncertainties of, and policy choices for, solar geoengineering, and foster critical appraisal of its risks and benefits."

Quartz: A bipartisan US group introduced another bill to support a controversial climate technology

"The support it adds for direct air capture is perhaps just as essential, because that’s a technology nearly every climate model says we’ll need to scale up in the next few decades to avoid cataclysmic climate change. Direct air capture, when powered by carbon-neutral sources, is a negative-emissions machine. And the longer we take to cut global emissions, the greater our need for a negative-emissions technology will be."

Daily Mail: Could a man-made chemical sunshade ease global warming? Scientists in developing nations reveal 'crazy' research to dim the sun

"Research into 'solar geo-engineering' plan is now dominated by rich nations. The technique would mimic volcanic eruptions to cool Earth by dimming the sun. But, scholars from developing countries argue that the poor are most vulnerable. They argue developing countries 'must lead on solar geo-engineering research'"
