"This post takes an in-depth look at a few Antarctic glacial geoengineering proposals, the problems they present for long-term governance, and how the law of Antarctica would frame oversight of early scientific research."

"From building floating cities and towering sea walls to erecting snow cannons in Antarctica to help replenish melting polar ice, scientists and urban planners have proposed all sorts of schemes to defend against rising seas — one of the most worrisome consequences of climate change."

"With the West Antarctic ice sheet starting to melt, which can lead to a rise in sea levels, a team of researchers has come up with a radical proposal: To artificially create snow to thicken up the ice sheet.

Feldmann, J.; Levermann, A.; Mengel, M. (2019): Stabilizing the West Antarctic Ice Sheet by surface mass deposition. In: Science Advances 5 (7), eaaw4132. DOI: 10.1126/sciadv.aaw4132.

"There is evidence that a self-sustaining ice discharge from the West Antarctic Ice Sheet (WAIS) has started, potentially leading to its disintegration. The associated sea level rise of more than 3m would pose a serious challenge to highly populated areas including metropolises such as Calcutta, Shanghai, New York City, and Tokyo. Here, we show that the WAIS may be stabilized through mass deposition in coastal regions around Pine Island and Thwaites glaciers."
