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."

E&E News: Can we refreeze the Arctic? Scientists are beginning to ask

"The Rhône is one of many glaciers around the world that have noticeably shrunk in recent decades. The blankets are a simple fix, but they seem to help — Swiss glaciologist David Volken has previously suggested to Agence France-Presse that they may reduce melting by up to 70 percent."
