Gertler, Charles G., Paul A. O’Gorman, Ben Kravitz, John C. Moore, Steven J. Phipps, and Shingo Watanabe. 2020: “Weakening of the Extratropical Storm Tracks in Solar Geoengineering Scenarios.” Geophysical Research Letters. https://doi.org/10.1029/2020gl087348.

‌"Here, we first analyze climate model simulations from experiment G1 of the Geoengineering Model Intercomparison Project (GeoMIP), in which a reduction in incoming solar radiation balances a quadrupling of CO₂. The Northern Hemisphere extratropical storm track weakens by a comparable amount in G1 as it does for increased CO₂ only. The Southern Hemisphere storm track also weakens in G1, in contrast to a strengthening and poleward shift for increased CO₂."

"The feasibility of large-scale biological CO₂ removal to achieve stringent climate targets remains unclear. Direct Air Carbon Capture and Storage (DACCS) offers an alternative negative emissions technology (NET) option. Here we conduct the first inter-model comparison on the role of DACCS in 1.5 and 2 °C scenarios, under a variety of techno-economic assumptions."

Implications from a field experiment and numerical modelling. In: International Journal of Greenhouse Gas Control 84, S. 190–203. DOI: 10.1016/j.ijggc.2019.03.012.

"Existing wells pose a risk for the loss of carbon dioxide (CO₂) from storage sites, which might compromise the suitability of carbon dioxide removal (CDR) and carbon capture and storage (CCS) technologies as climate change mitigation options. Here, we show results of a controlled CO₂ release experiment at the Sleipner CO₂ storage site and numerical simulations that evaluate the detectability and environmental consequences of a well leaking CO₂ into the Central North Sea (CNS)."

"Coastal wetlands (mangrove, tidal marsh and seagrass) sustain the highest rates of carbon sequestration per unit area of all natural systems, primarily because of their comparatively high productivity and preservation of organic carbon within sedimentary substrates. [...] Our results suggest that coastal wetlands characteristic of tectonically stable coastlines have lower carbon storage owing to a lack of accommodation space and that carbon sequestration increases according to the vertical and lateral accommodation space created by RSLR. Such wetlands will provide long-term mitigating feedback effects that are relevant to global climate–carbon modelling."
