Grieger, Khara D.; et al. (2019): Emerging risk governance for stratospheric aerosol injection as a climate management technology

Grieger, Khara D.; Felgenhauer, Tyler; Renn, Ortwin; Wiener, Jonathan; Borsuk, Mark (2019): Emerging risk governance for stratospheric aerosol injection as a climate management technology. In Environ Syst Decis 103 (46), pp. 1–12. DOI: 10.1007/s10669-019-09730-6.

"Robust governance strategies are needed to manage the many potential benefits, risks, and uncertainties related to SAI. This perspective reviews the International Risk Governance Council (IRGC)’s guidelines for emerging risk governance (ERG) as an approach for responsible consideration of SAI, given the IRGC’s experience in governing other more conventional risks. We examine how the five steps of the IRGC’s ERG guidelines would address the complex, uncertain, and ambiguous risks presented by SAI."

Digital Trends: Geoengineering is risky and unproven, but soon it might be necessary

"Imagine the azure blue skies of summer fading to a hazy white as light-scattering aerosols are injected into Earth’s upper atmosphere. Imagine a planet covered with giant artificial chemical sponges leeching gases out of the air that we breathe. Imagine filling the Earth’s oceans with millions of pounds of calcium bicarbonate to alter the levels of acidification."

Wired: The Side Effects of Solar Geoengineering Could Be Minimal

"It sounds like a drastic course of action: inject stuff high into Earth’s atmosphere to reflect a little sunlight and help counteract global warming. Then again, injecting a bunch of greenhouse gas into the atmosphere and warming the planet was pretty drastic, too."

The Guardian: US and Saudi Arabia blocking regulation of geoengineering, sources say

"The United States and Saudi Arabia have hamstrung global efforts to scrutinise climate geoengineering in order to benefit their fossil fuel industries, according to multiple sources at the United Nations environment assembly, taking place this week in Nairobi."

Geoengineerin Monitor: Why is Geoengineering being discussed at UNEA, and how should civil society respond?

"It has been almost a decade after the landmark moratorium on all climate-related geoengineering was passed by the Convention on Biological Diversity (CBD) in 2010 and several years since the decision of parties to the London Protocol of the London Convention on marine dumping prohibiting ocean fertilization and potentially other marine geoengineering proposals. Today, geoengineering is on the agenda of another UN body: the UN Environment Assembly."

SDG.IISD: Geoengineering at UNEA-4: Why the SDGs Require a Governance Debate Based on Precaution, Rights and Fairness

"Geoengineering – large-scale intentional manipulation of the Earth’s natural systems such as oceans, lands, atmosphere and carbon cycles – is increasingly being presented as a strategy to counteract, dilute or delay climate change and its effects. The UN Environment Assembly (UNEA) is expected to address the issue at its fourth session, convening in Nairobi, Kenya, from 11-15 March 2019, and should do so with caution."

Chatham House: Cool idea or hi-tech madness?

"As the threat from climate change looms ever larger, growing attention is being paid to proposals that sound as if they come straight from a sci-fi novel. One idea is to spray the stratosphere with particulates to reflect sunlight, thus reducing the temperature of planet Earth."

Legal Planet: Does the Fossil Fuel Industry Support Geoengineering?

"Geoengineering is controversial in the climate change community, and understandably so. Proposed interventions like negative emissions technologies (a.k.a. carbon dioxide removal) and solar geoengineering (a.k.a. solar radiation management or SRM) involve large-scale intervention in the climate system that could have adverse physical or social impacts. At the same time, some geoengineering methods could substantially reduce climate change."

Project Syndicate: Geoengineering is a Dangerous Distraction

"A growing number of people are now considering the once-unthinkable strategy of geoengineering our way out of the climate crisis. Proposed approaches vary widely, but all share a few key features: they are technologically uncertain, environmentally risky, and more likely to accelerate the climate crisis than to reverse it."

E&E News: Here's the research to watch in 2019

"Amid concern about the Paris Agreement's rapidly approaching global climate targets, geoengineering is a growing area of focus. One widely discussed, but highly controversial, hypothetical proposal involves spraying reflective aerosols into the atmosphere to beam sunlight away and cool the planet. It's called solar radiation management, or solar geoengineering."
