Independent: Snow cannons could be used to repair melting ice sheets and prevent sea level rise, scientists suggest

"Vast snow cannons could be used to repair the West Antarctic ice sheet and prevent catastrophic sea level rise, leading climate scientists have suggested."

Call for Sessions: Securing sustainable futures. Designing, planning, and making decisions on policies, practices, and infrastructures under deep uncertainty

Deadline: 1. April 2019

"We are now inviting proposals for sessions related to the theme of ‘Securing sustainable futures’. Session proposals can focus on specific methods or approaches and how these are or could be used across different application domains, or instead focus on the treatment of deep uncertainty within a specific domain or context."

arsTECHNICA: Geoengineering could stop warming but comes with side of sea-level rise

"Since we've only made moderate progress in cutting greenhouse gas emissions, climate science has turned to seriously investigating options that have typically been in the “far-fetched” category. That includes something called “solar radiation management”—increasing the reflectivity of the atmosphere to, in essence, shade the planet. That could provide a bit of human-caused cooling to temporarily offset some human-caused warming."

EGU: Glacial engineering could limit sea-level rise, if we get our emissions under control

"Targeted engineering projects to hold off glacier melting could slow down the collapse of ice sheets and limit sea-level rise, according to a new study published in the European Geosciences Union journal The Cryosphere. While an intervention similar in size to existing large civil engineering projects could only have a 30% chance of success, a larger project would have better odds of holding off ice-sheet collapse. But study authors Michael Wolovick and John Moore caution that reducing emissions still remains key to stopping climate change and its dramatic effects."

GlacierHub: Solar Geoengineering Could Limit Sea-Level Rise from Cryosphere

"Geoengineering, as it relates to climate change, falls into two categories. The first, atmospheric carbon removal, entails physically removing carbon dioxide from the air to reduce greenhouse gas concentrations and limit temperature rise. The second, solar geoengineering, involves injecting sulfur dioxide or another aerosol into the stratosphere to reflect a portion of incoming solar radiation, again limiting temperature rise."

Forbes: How Much Sea Level Rise Is Actually Locked in?

"Under the lowest of the IPCC’s four scenarios, RCP2.6, peak temperature rise of 2 degrees C will be reached before 2100, and sea level rise will be less than about a half meter. However, due to lag effects in ocean warming and ice melt, sea level will continue to rise for centuries. Rise can theoretically be reduced by negative carbon emissions or geoengineering."

Irvine, Peter J.; et al. (2018): Brief communication. Understanding solar geoengineering's potential to limit sea level rise requires attention from cryosphere experts

Irvine, Peter J.; Keith, David W.; Moore, John (2018): Brief communication. Understanding solar geoengineering's potential to limit sea level rise requires attention from cryosphere experts. In: The Cryosphere 12 (7), S. 2501–2513. DOI: 10.5194/tc-12-2501-2018.

"Here we review the literature on solar geoengineering and the cryosphere and identify the key uncertainties that research could address. Solar geoengineering may be more effective at reducing surface melt than a reduction in greenhouse forcing that produces the same global-average temperature response. Studies of natural analogues and model simulations support this conclusion."

Wolovick, Michael J.; et al. (2018): Stopping the Flood. Could We Use Targeted Geoengineering to Mitigate Sea Level Rise?

Wolovick, Michael J.; Moore, John C. (2018): Stopping the Flood. Could We Use Targeted Geoengineering to Mitigate Sea Level Rise? In: The Cryosphere Discuss., S. 1–20. DOI: 10.5194/tc-2018-95.

"Here, we use a suite of coupled ice–ocean flowband simulations to explore whether targeted geoengineering using an artificial sill or artificial ice rises could counter a collapse. Successful interventions occur when the floating ice shelf regrounds on the pinning points, increasing buttressing and reducing ice flux across the grounding line. Regrounding is more likely with a continuous sill that is able to block warm water transport to the grounding line."
