Newton, Robert; et al. (2016): White Arctic vs. Blue Arctic. A case study of diverging stakeholder responses to environmental change

Newton, Robert; Pfirman, Stephanie; Schlosser, Peter; Tremblay, Bruno; Murray, Maribeth; Pomerance, Rafe (2016): White Arctic vs. Blue Arctic. A case study of diverging stakeholder responses to environmental change. In Earth's Future. DOI 10.1002/2016EF000356

"Even if global warming can be reversed, some people will experience ice-free summers before perennial sea ice begins to return. We ask: How will future generations feel about bringing sea ice back where they have not experienced it before? How will conflicted interests in ice-covered vs. ice-free conditions be resolved? What role will science play in these debates?"

Mengis, Nadine; et al. (2016): Assessing climate impacts and risks of ocean albedo modification in the Arctic

Mengis, Nadine; Martin, T.; Keller, David P.; Oschlies, Andreas (2016): Assessing climate impacts and risks of ocean albedo modification in the Arctic. In J. Geophys. Res. Oceans. DOI 10.1002/2015JC011433.

"This study assesses climate impacts and risks of idealized Arctic Ocean albedo modification (AOAM), a proposed climate engineering method, during transient climate change simulations with varying representative concentration pathway (RCP) scenarios. We find no potential for reversing trends in all assessed Arctic climate metrics under increasing atmospheric CO2 concentrations."

National Geographics: Santa's Home Is Melting. Will We Ever Bring It Back?

"Later this century, after the North Pole is open water, we may have the technology to bring back the Arctic ice—if we want to."

The Conversation: Blocking out the sun won’t fix climate change – but it could buy us time

"Could we directly engineer the climate and refreeze the poles? The answer is probably yes, and it could be a cheap thing to achieve – maybe costing only a few billion dollars a year. But doing this – or even just talking about it – is controversial."

Scientific American: Can Geoengineering Save the World's Ice?

"Adding aerosols to the atmosphere to reflect more sunlight might slow the loss of glaciers but not stop it"

Applegate, Patrick J.; Keller, Klaus (2015): How effective is albedo modification (solar radiation management geoengineering) in preventing sea-level rise from the Greenland Ice Sheet?

Applegate, Patrick J.; Keller, Klaus (2015): How effective is albedo modification (solar radiation management geoengineering) in preventing sea-level rise from the Greenland Ice Sheet? In Environ. Res. Lett. 10 (8), p. 84018–84018. DOI 10.1088/1748-9326/10/8/084018

"Here, we assess AM's ability to reduce GIS sea-level contributions over decades to centuries, using a simplified ice sheet model. We drive this model using a business-as-usual base temperature forcing scenario, as well as scenarios that reflect AM-induced temperature stabilization or temperature drawdown."

Haqq-Misra, Jacob (2015): Should we geoengineer larger ice caps? (forthcoming)

Haqq-Misra, Jacob (2015): Should we geoengineer larger ice caps? (forthcoming). In Futures. DOI 10.1016/j.futures.2015.07.002.

"Intentionally extending Earth's glacial coverage will require uninterrupted commitment to this program for millenia but would ultimately reach a cooler equilibrium state where geoengineering is no longer needed. Whether or not this program is ever attempted, this concept illustrates the need to identify preference among potential climate states to ensure the long-term success of civilization."

Washington Post: Climate engineering would cool down the planet — but it may not save West Antarctica

"That’s why a new study recently accepted in Geophysical Research Letters could be so significant. For it calls into question whether geoengineering — at least using sulfate aerosols — can actually save this ice sheet, which is already beginning to be destabilized in our warming world."

The Independent: Artificially manipulating Arctic climate by 'whitening' surface of ocean to reflect sunlight back into space will fail, say scientists

Response to Cvijanovic, Ivana; et al. (2015). "Some have suggested that this radical approach should be considered in a global emergency if the summer sea ice of the Arctic disappears completely"
