Columbia Climate Center (2016): A 5˚C Arctic in a 2˚C World. Challenges and Recommendations for Immediate Action from the July 21-22, 2016 Workshop

Columbia Climate Center (2016): A 5˚C Arctic in a 2˚C World. Challenges and Recommendations for Immediate Action from the July 21-22, 2016 Workshop. WWF; Arctic 21; Woods Hole Research Center.

Outcomes: "To avert massive environmental impacts beyond the time frame of a few decades, it is critical to immediately scale up implementation of alternative energy production, as well as decarbonization of the energy system. We also should greatly increase efforts in research and development and subsequent deployment of carbon dioxide removal (CDR) on a global scale."

the guardian: Time to listen to the ice scientists about the Arctic death spiral

"The Arctic’s ice is disappearing. We must reduce emissions, fast, or the human castastrophe predicted by ocean scientist Peter Wadhams will become reality. [...] He wants global action to find new ways to remove carbon from the atmosphere, and is not afraid of nuclear power – both of which answers can be swallowed – but he also argues for a colossal, global research programme in geo- engineering."

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."

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."
