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."

GreenBiz: Could this geoengineering venture help save the ice caps?

"Leslie Field, founder and CEO of Ice911, a Silicon Valley nonprofit research corporation, has been doing just that. Field — a micro-electro-mechanical systems and nanotechnology consultant, Stanford consulting professor and inventor — has been collaborating with other scientists and engineers to "restore the earth's refrigerator by slowing down the melt of polar ice," as she explained to me recently. Now, the organization is seeking ways to scale its idea."

Nalam, Aditya; et al. (2017): Effects of Arctic geoengineering on precipitation in the tropical monsoon regions

Nalam, Aditya; Bala, Govindasamy; Modak, Angshuman (2017): Effects of Arctic geoengineering on precipitation in the tropical monsoon regions. In Clim Dyn 41 (1), p. 1738. DOI: 10.1007/s00382-017-3810-y.

"In this study, we investigate and quantify the implications of this ITCZ shift due to Arctic geoengineering for the global monsoon regions using the Community Atmosphere Model version 4 coupled to a slab ocean model. A doubling of CO2 from pre-industrial levels leads to a warming of ~6 K in the Arctic region and precipitation in the monsoon regions increases by up to ~15%. In our Arctic geoengineering simulation which illustrates a plausible latitudinal distribution of the reduction in sunlight, an addition of sulfate aerosols (11 Mt) in the Arctic stratosphere nearly offsets the Arctic warming due to CO2 doubling but this shifts the ITCZ southward by ~1.5° relative to the pre-industrial climate."
