TechCrunch: At what point do we admit that geoengineering is an option?

"We already know how to cool the planet without reducing carbon. The solution is so simple it’s almost laughable: just make our clouds a little more reflective, so they reflect more of the sun’s light, and thus reduce our heat."

Gattuso, J.; et al. (2018): Ocean Solutions to Address Climate Change and Its Effects on Marine Ecosystems

Gattuso, J.; Magnan, A.; Bopp, L.; Cheung, W.; Duarte, C.; Hinkel, J. et al. (2018): Ocean Solutions to Address Climate Change and Its Effects on Marine Ecosystems. In: Front. Mar. Sci. 5, S. 3. DOI: 10.3389/fmars.2018.00337.

"A comprehensive and systematic assessment of 13 global- and local-scale, ocean-based measures was performed to help steer the development and implementation of technologies and actions toward a sustainable outcome. We show that (1) all measures have tradeoffs and multiple criteria must be used for a comprehensive assessment of their potential, (2) greatest benefit is derived by combining global and local solutions, some of which could be implemented or scaled-up immediately, (3) some measures are too uncertain to be recommended yet, (4) political consistency must be achieved through effective cross-scale governance mechanisms, (5) scientific effort must focus on effectiveness, co-benefits, disbenefits, and costs of poorly tested as well as new and emerging measures."

NextBigFuture: Point of no return for climate action is point when Geoengineering will start

"So-called solar geoengineering aims to cool the planet by deflecting some of the Sun’s incoming rays. Ideas for accomplishing this include the dispersion of light-scattering particles in the upper atmosphere, which would mimic the cooling effect of major volcanic eruptions."

The Conversation: Geoengineering the Great Barrier Reef needs strong rules

"A recent conference showcased new possibilities for enhancing Reef resilience, including boosting coral abundance and geoengineering techniques that would manipulate local conditions to reduce ocean temperatures."

González, Miriam Ferrer; et al. (2018): Enhanced Rates of Regional Warming and Ocean Acidification after Termination of Large-scale Ocean Alkalinization

González, Miriam Ferrer; Ilyina, Tatiana; Sonntag, Sebastian; Schmidt, Hauke (2018): Enhanced Rates of Regional Warming and Ocean Acidification after Termination of Large-scale Ocean Alkalinization. In: Geophys. Res. Lett. DOI: 10.1029/2018GL077847.

"Termination effects of large‐scale Artificial Ocean Alkalinization (AOA) have received little attention because AOA was assumed to pose low environmental risk. With the Max‐Planck‐Institute Earth System Model, we use emission‐driven AOA simulations following the Representative Concentration Pathway 8.5 (RCP8.5). We find that after termination of AOA warming trends in regions of the Northern hemisphere become ∼50% higher than those in RCP8.5 with rates similar to those caused by termination of solar geoengineering over the following three decades after cessation (up to 0.15 K/year)."
