Grist: Carbon capture ‘moonshot’ moves closer as billions of dollars pour in

"In an eye-catching recent deal, a consortium including Amazon and Microsoft invested in CarbonCure Technologies, a Canadian firm seeking to slash the carbon dioxide emissions of concrete. Producing cement, the key ingredient in concrete, creates so much CO2 that if the industry were a country, only China and the United States would emit more over the course of a year."

The Millbrook Independent: The Futility of Soil Carbon Sequestration

"For a long time, farmers have realized that soil organic matter improves the quality of soils, by improving water-hold capacity, friability, and nutrient content. But, however we do it—fertilization, irrigation, manuring, reduced tillage, and planting cover crops—increasing soil organic matter doesn’t look like such a good idea to mitigate climate change. The chemistry of humus substances includes a substantial amount of nitrogen and phosphorus that will limit our efforts."

CarbonBrief: Influential academics reveal how China can achieve its ‘carbon neutrality’ goal

"China’s electricity system would need to reach net-zero CO2 emissions by 2050 if the country is to meet its recently announced target of “carbon neutrality” before 2060."

C2G Guest Post: Solar Geoengineering, Compensation, and Parametric Insurance: Insights from the Pacific

"Compensation is a central issue in considering the possible future deployment of solar geoengineering [1] for two reasons. First and most obvious, corrective justice would require compensating those who are harmed. Second, without a credible compensation mechanism, many states would likely oppose deployment by imposing high short-term costs such as trade or financial sanctions on would-be deployers."

Strassburg, Bernardo B. N.; et al. (2020): Global priority areas for ecosystem restoration

Strassburg, Bernardo B. N.; Iribarrem, Alvaro; Beyer, Hawthorne L.; Cordeiro, Carlos Leandro; Crouzeilles, Renato; Jakovac, Catarina C. et al. (2020): Global priority areas for ecosystem restoration. In Nature. DOI: 10.1038/s41586-020-2784-9.

"Here we develop and apply a multicriteria optimization approach that identifies priority areas for restoration across all terrestrial biomes, and estimates their benefits and costs. We find that restoring 15% of converted lands in priority areas could avoid 60% of expected extinctions while sequestering 299 gigatonnes of CO2—30% of the total CO2 increase in the atmosphere since the Industrial Revolution."

Horton, Joshua B.; et al. (2020): Parametric Insurance for Solar Geoengineering: Insights from the Pacific Catastrophe Risk Assessment and Financing Initiative

Horton, Joshua B.; Lefale, Penehuro; Keith, David (2020): Parametric Insurance for Solar Geoengineering: Insights from the Pacific Catastrophe Risk Assessment and Financing Initiative. In Global Policy. DOI: 10.1111/1758-5899.12864.

"Parametric insurance, which delivers payouts when specific physical indices (such as wind speed) cross predefined thresholds, was recently proposed by two of us as a compensation mechanism for SG with the potential to ease disagreements about the technology and to facilitate cooperative deployment; we refer to this proposal as reduced‐rate climate risk insurance for solar geoengineering, or ‘RCG’. Here we probe the plausibility of RCG by exploring the Pacific Catastrophe Risk Assessment and Financing Initiative (PCRAFI), a sovereign risk pool providing parametric insurance coverage against tropical cyclones and earthquakes/tsunamis to Pacific island countries since 2013."

Manley, Kyle; et al. (2020): Modeling the Dynamic Landscape Evolution of a Volcanic Coastal Environment Under Future Climate Trajectories

Manley, Kyle; Salles, T.; Müller, R. D. (2020): Modeling the Dynamic Landscape Evolution of a Volcanic Coastal Environment Under Future Climate Trajectories. In Front. Earth Sci. 8, p. 437. DOI: 10.3389/feart.2020.550312.

"Olivine weathering is a natural process that sequesters carbon out of the atmosphere, but is now being proposed as a strategy that can be artificially implemented to assist in the mitigation of anthropogenic carbon emissions. We use the landscape evolution model Badlands to identify a region (Tweed Caldera catchment in Eastern Australia) that has the potential for naturally enhanced supply of mafic sediments, known to be a carbon sink, into coastal environments."
