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."

C2G: Policy Brief: Climate-Altering Technologies and the Arctic. Carnegie Climate Governance Initiative

‘C2G (2019). C2G Policy Brief: Climate-Altering Technologies and the Arctic. Carnegie Climate Governance Initiative (C2G). New York. 2019’ Version 20191004

"In response to the risks posed by climate change, some are considering the viability of developing and deploying climate-altering technologies in the Arctic such as Solar Radiation Modification (SRM) and large-scale Carbon Dioxide Removal (CDR)."

C2G: Arctic Circle Assembly

10. October 2019, Reykjavík / Iceland

"The Arctic plays a key role in the global climate system. This makes the region an area of special interest for those considering the viability of climate-altering technologies, including Solar Radiation Modification and large-scale Carbon Dioxide Removal. In addition, others are considering interventions to engineer or protect ice in order to slow or reverse ice melt. But is there adequate governance in place to protect people and ecosystems should these climate-altering technologies be tested or used?"

Drollette, D. (2019): What if the Arctic melts, and we lose the great white shield? Interview with environmental policy expert Durwood Zaelke

Drollette, Dan (2019): What if the Arctic melts, and we lose the great white shield? Interview with environmental policy expert Durwood Zaelke. In Bulletin of the Atomic Scientists 75 (5), pp. 239–246. DOI: 10.1080/00963402.2019.1654269.

"In this interview, Durwood Zaelke, president of the Institute for Governance & Sustainable Development, outlines the climate change problem in the Arctic, tells of the increasing speed with which the ice is melting, and outlines some possible solutions, ranging from relatively benign approaches to methods that call for increasingly more intrusive tinkering with the planet."
