Turvey, C.; Wilson, S.; Hamilton, J.; Tait, A.; McCutcheon, J.; Beinlich, A. et al. (2018): Hydrotalcites and hydrated Mg-carbonates as carbon sinks in serpentinite mineral wastes from the Woodsreef chrysotile mine, New South Wales, Australia. Controls on carbonate mineralogy and efficiency of CO2 air capture in mine tailings. In: International Journal of Greenhouse Gas Control 79, S. 38–60. DOI: 10.1016/j.ijggc.2018.09.015.

"Carbon mineralisation of ultramafic mine tailings can reduce net emissions of anthropogenic carbon dioxide by reacting Mg-silicate and hydroxide minerals with atmospheric CO₂ to produce carbonate minerals. We investigate the controls on carbonate mineral formation at the derelict Woodsreef chrysotile mine (New South Wales, Australia). Quantitative XRD was used to understand how mineralogy changes with depth into the tailings pile, and shows that hydromagnesite [Mg₅(CO₃)₄(OH)₂·4H₂O], is present in shallow tailings material (<40 cm), while coalingite [Mg₁₀Fe³⁺₂(CO₃)(OH)₂₄·2H₂O] and pyroaurite [Mg₆Fe³⁺₂(CO₃)(OH)₁₆·4H₂O] are forming deeper in the tailings material."

"Technologies for Solar Radiation Management (SRM) could limit global warming by manipulating the Earth’s radiation balance. A major objection to SRM is the termination problem: the catastrophic consequences that are likely to result from its sudden discontinuation. The termination problem limits the reversibility of policy choices and poses the risk of inadvertent or enforced program collapse."

"Here we investigate impacts of shipping emissions on Arctic climate using a fully coupled Earth system model (CESM 1.2.2) and a suite of newly developed projections of 21st‐century trans‐Arctic shipping emissions. We find that trans‐Arctic shipping will reduce Arctic warming by nearly 1 °C by 2099, due to sulfate‐driven liquid water cloud formation. Cloud fraction and liquid water path exhibit significant positive trends, cooling the lower atmosphere and surface."

"Global-scale solar geoengineering raises critical ethical questions, including questions of distributive, procedural, and intergenerational justice. Although geoengineering is sometimes framed as a response to injustice, insofar as it might benefit those most vulnerable to climate-related harms, geoengineering also has the potential to exacerbate climate injustice, especially if control of research, governance, and potential plans for deployment remains concentrated in the hands of a few. The scope and scale of solar geoengineering, the diverse concerns it raises, and the lack of consensus surrounding it pose particular challenges for justice."
