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."

MacMartin, D.; et al. (2019): Timescale for Detecting the Climate Response to Stratospheric Aerosol Geoengineering

MacMartin, D.; Wang, W.; Kravitz, B.; Tilmes, S.; Richter, J.; Mills, M. (2019): Timescale for Detecting the Climate Response to Stratospheric Aerosol Geoengineering. In: J. Geophys. Res. Atmos. 41 (3), S. 1738. DOI: 10.1029/2018JD028906.

"Stratospheric aerosol geoengineering could be used to maintain global mean temperature despite increased atmospheric greenhouse gas (GHG) concentrations, for example, to meet a 1.5 or 2 °C target. While this might reduce many climate change impacts, the resulting climate would not be the same as one with the same global mean temperature due to lower GHG concentrations. The primary question we consider is how long it would take to detect these differences in a hypothetical deployment. We use a 20‐member ensemble of stratospheric sulfate aerosol geoengineering simulations in which SO2 is injected at four different latitudes to maintain not just the global mean temperature, but also the interhemispheric and equator‐to‐pole gradients."

Svoboda, T.; et al. (2019): The potential for climate engineering with stratospheric sulfate aerosol injections to reduce climate injustice

Svoboda, T.; Irvine, P.; Callies, D.; Sugiyama, M. (2019): The potential for climate engineering with stratospheric sulfate aerosol injections to reduce climate injustice. In: Journal of Global Ethics 15 (16), S. 1–16. DOI: 10.1080/17449626.2018.1552180.

"Climate engineering with stratospheric sulfate aerosol injections (SSAI) has the potential to reduce risks of injustice related to anthropogenic emissions of greenhouse gases. Relying on evidence from modeling studies, this paper makes the case that SSAI could have the potential to reduce many of the key physical risks of climate change identified by the Intergovernmental Panel on Climate Change. Such risks carry potential injustice because they are often imposed on low-emitters who do not benefit from climate change."

The Hill: Geoengineering is one way to fight climate change and cool the planet

"In 2006, James Hansen, noted climate activist and at the time director of the Goddard Institute for Space Studies, made a dire prediction. 'We have at most 10 years, not 10 years to decide upon action, but 10 years to alter fundamentally the trajectory of global greenhouse emissions,' he wrote. If we fail to do so, he added, 'Climate disasters will become unavoidable.'"

SingularityHub: Will These Massive Geoengineering Projects Fix the Earth—Or Break It?

"From planting continent-long forests to inducing rainfall, researchers have begun proposing, testing, and in some cases implementing large-scale geoengineering projects to radically transform the planet. These projects are designed to solve problems such as desertification, drought, or excess carbon dioxide in the atmosphere, all with the ultimate goal of combating climate change."
