The Guardian: 10 million snowblowers? Last-ditch ideas to save the Arctic ice

"As the realization sets in that existing emission reductions and renewable energy programs in place won’t be enough to save the Arctic, alternative geoengineering projects have gained traction as scientists look for a last-ditch solution."

Eos: Implications of Sea Ice Management for Arctic Biogeochemistry

"Geoengineering strategies to slow sea ice melting would affect not only Earth’s climate but also the biology and chemistry of the oceans, atmosphere, and ice."

Daniel Bodansky; Hugh Hunt (2020): Arctic Climate Interventions

Daniel Bodansky; Hugh Hunt (2020): Arctic Climate Interventions. In The International Journal of Marine and Coastal Law 35 (3), pp. 596–617. DOI: 10.1163/15718085-BJA10035.

"Even if one believes that global climate interventions, such as injecting aerosols into the stratosphere to scatter sunlight, pose unacceptable risks and should be disqualified from consideration, Arctic interventions differ in important respects. They are closer in kind to conventional mitigation and adaptation and should be evaluated in similar terms. It is unclear whether they are feasible and would be effective in saving the Arctic. But given the importance of the Arctic, they should be investigated fully."

Sierra Club: Could Geoengineering Help Save the World’s Ice?

"Slowing the rate of ice melt there and elsewhere would allow for critical adaptation in at-risk areas, such as islands and coastal cities. Some researchers are looking to geoengineering to accomplish this. Michael Wolovick, a researcher at Beijing Normal University, is one of them. He and his colleague John Moore have studied a number of geoengineering strategies to prevent or slow the collapse of Thwaites Glacier."

Phys.org: Can Arctic 'ice management' combat climate change?

"According to a much-debated geo-engineering approach, both sea-ice retreat and global warming could be slowed by using millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter."

Zampieri, L.; et al. (2019): Sea Ice Targeted Geoengineering Can Delay Arctic Sea Ice Decline but not Global Warming

Zampieri, Lorenzo; Goessling, Helge F. (2019): Sea Ice Targeted Geoengineering Can Delay Arctic Sea Ice Decline but not Global Warming. In Earth's Future 7. DOI: 10.1029/2019EF001230.

"To counteract global warming, a geoengineering approach that aims at intervening in the Arctic ice‐albedo feedback has been proposed. A large number of wind‐driven pumps shall spread seawater on the surface in winter to enhance ice growth, allowing more ice to survive the summer melt. We test this idea with a coupled climate model by modifying the surface exchange processes such that the physical effect of the pumps is simulated."
