Harding, A.; et al. (2018): The economics of geoengineering

Harding, A.; Moreno-Cruz, J. (2018): The economics of geoengineering. In: Letcher T. (ed.): MANAGING GLOBAL WARMING. An interface of technology and human issues. [S.l.]: ELSEVIER ACADEMIC PRESS, S. 729–750.

"Geoengineering provides an alternative strategy from abatement to counteract or mask impacts of anthropogenic climate change. Geoengineering strategies can be classified as either solar radiation management (SRM) or carbon dioxide removal (CDR). SRM strategies are cheap, quick, but imperfect. CDR strategies are expensive, slow, but perfect and can generate negative net emissions. High abatement costs and shared global benefits have created a free-rider problem, but properties of geoengineering have the potential to disrupt that impasse. Geoengineering can also introduce new problems through additional risks and uncertainties. Even if the use of geoengineering is found to be optimal, strategic decision making may produce suboptimal outcomes. Over the past decade, research has examined if geoengineering is a serious alternative and when the benefits of using it outweigh the costs."

InTheseTimes: To Block Out the Sun

"But more dramatic approaches have crept into policy discussions, like solar radiation management, known as SRM. First imagined by scientists during the Cold War, SRM promises a comparatively cheap, quick fix: the continuous dispersal of aerosols into the atmosphere to reflect and absorb sunlight, cooling the planet. In effect, SRM means dimming the sun."

Project Syndicate: A Radically Realistic Climate Vision

"The IPCC does not bet on geo-engineering proposals – for example, deep-ocean sequestration of massive amounts of atmospheric carbon dioxide, or “dimming the sun” by spraying the atmosphere with aerosols – to combat global warming. These largely theoretical solutions could have untold consequences for people and ecosystems, worsening not only the climate crisis, but also the other social and ecological crises we face."

arsTECHNICA: Geoengineering could stop warming but comes with side of sea-level rise

"Since we've only made moderate progress in cutting greenhouse gas emissions, climate science has turned to seriously investigating options that have typically been in the “far-fetched” category. That includes something called “solar radiation management”—increasing the reflectivity of the atmosphere to, in essence, shade the planet. That could provide a bit of human-caused cooling to temporarily offset some human-caused warming."

Union of Concerned Scientists: Geoengineering: Scarier than a Zombie Apocalypse? (Podcast)

"Just in time for Halloween, an episode that’ll scare the daylights out of you. Frank Keutsch joins us to explain what geoengineering is, why it isn’t a magic fix for climate change, and why we still need to greatly reduce CO2 emissions."

The Christian Science Monitor: Unintended consequences: Climate-hacking poses big ethical questions

"The idea of blotting out the sun, whether floated by Frédéric Bastiat or Montgomery Burns, has long stood as a metaphor for human arrogance."

Call for Abstracts: Ocean-based negative emission technologies: Feasibility, costs and side-effects (EGU)

Deadline: 10. January 2019

"In this session we want to bring together experts on ONETs to assess and discuss their feasibilities, costs, and side-effects. We explicitly also welcome experts working on interactions between, as well as mutual benefits of, ocean- and land-based NETs."

California Magazine: Reading Roundup: Volcanic Umbrellas, Student Oscars, More

"As climate change increasingly alters our lifestyles and embeds itself into our collective consciousness, geoengineering—in this case, humans playing volcano to replicate this cooling event—became a fascinating idea."
