Fasullo, J.; et al. (2018): Persistent polar ocean warming in a strategically geoengineered climate

Fasullo, J.; Tilmes, S.; Richter, J.; Kravitz, B.; MacMartin, D.; Mills, M.; Simpson, I. (2018): Persistent polar ocean warming in a strategically geoengineered climate. In: Nature Geosci. DOI: 10.1038/s41561-018-0249-7.

"Enhancement of the Earth’s albedo through the injection of sulfate aerosols into the stratosphere has been proposed as an approach to offset some of the adverse effects of climate change. Here we analyse an ensemble of simulations of the twenty-first century climate designed to explore a strategic geoengineering approach. Specifically, stratospheric sulfur injections are imposed at 15° and 30° in both hemispheres with the aim to minimize the changes in surface temperature, both in the global mean and in its gradients between hemispheres and from equator to pole."

YouTube: Stopping the flood – Can we engineer ice sheets and save the homes of a billion people?

"Open lecture of Research Professor John C. Moore from the Arctic Centre on how we could slow sea-level rise by stabilizing the ice sheets. The lecture took place on United Nations Day on 24th October 2018 in Rovaniemi, Finland."

Samoaobserver: Climate engineering is the potential game changer we need to confront

"In his article “Geoengineering worsen climate and hurts Paris Agreement” (October 11, 2018, posted online October 15, 2018), Fiu Mataése Elisara, Executive Director – O.L.S.S.I contends geoengineering  (climate engineering) '…is a deliberate attempt by the rich to distract from the real priorities of fossil fuel emission reductions. A false mitigation solution that will worsen climate change and indeed does nothing but hurts the Paris Agreement.'"

Field, L.; et al. (2018): Increasing Arctic Sea Ice Albedo Using Localized Reversible Geoengineering

Field, L.; Ivanova, D.; Bhattacharyya, S.; Mlaker, V.; Sholtz, A.; Decca, R. et al. (2018): Increasing Arctic Sea Ice Albedo Using Localized Reversible Geoengineering. In Earth's Future. DOI: 10.1029/2018EF000820.

"In this paper, a novel localized surface albedo modification technique is presented that shows promise as a method to increase multi‐year ice using reflective floating materials, chosen so as to have low subsidiary environmental impact. Detailed climate modeling studying the climate impact of such a method reveals more than 1.5 °C cooler temperatures over a large part of the Arctic when simulating global sea ice albedo modification. In a region north of Barents and Kara Seas temperatures have been reduced by 3 °C and in North Canada by almost 1 °C. Additionally, there are notable increases in sea ice thickness (20‐50 cm Arctic wide) and ice concentration (>15‐20% across large parts of central Arctic). These results suggest that the geoengineering technology proposed in this study may be a viable instrument for restoring Arctic ice. "

Care2: Trump Should Build a Wall — to Slow Sea Level Rise

"Yes, you read that correctly: A team of scientists and engineers is calling for a massive seawall to directly slow sea level rise by preventing glaciers from sliding off into the ocean in large chunks."

Eurasia Review: Geoengineering Polar Glaciers To Slow Sea-Level Rise

"Previous discussions of geoengineering have looked at global projects, like seeding the atmosphere with particles to reflect more sunlight. That’s what makes this focused approach more feasible, said Michael Wolovick, a postdoctoral research associate in Atmospheric and Oceanic Sciences at Princeton University and a co-author on the Comment."

Moore, John C.; et al. (2018): Geoengineer polar glaciers to slow sea-level rise

Moore, John C.; Gladstone, Rupert; Zwinger, Thomas; Wolovick, Michael (2018): Geoengineer polar glaciers to slow sea-level rise. In Nature 555 (7696), pp. 303–305. DOI: 10.1038/d41586-018-03036-4.

"Stalling the fastest flows of ice into the oceans would buy us a few centuries to deal with climate change and protect coasts, argue John C. Moore and colleagues."

Buck, Holly Jean (2018): Perspectives on solar geoengineering from Finnish Lapland. Local insights on the global imaginary of Arctic geoengineering

Buck, Holly Jean (2018): Perspectives on solar geoengineering from Finnish Lapland. Local insights on the global imaginary of Arctic geoengineering. In Geoforum 91, pp. 78–86. DOI: 10.1016/j.geoforum.2018.02.020.

"However, this concept has remained a global imaginary, grounded in coarse-resolution climate modeling. How do people actually living in the Arctic imagine themselves experiencing or shaping solar geoengineering? How can the experience of people in particular places inform discussions of solar geoengineering governance? This paper synthesizes perspectives from extended interviews with citizen stakeholders in Finnish Lapland. Rather than approaching solar geoengineering from the perspective of Arctic or local interests, respondents took a global view of its prospects and governance."
