Vielstädte, L.; Linke, P.; Schmidt, M.; Sommer, S.; Haeckel, M.; Braack, M.; Wallmann, K. (2019): Footprint and detectability of a well leaking CO2 in the Central North Sea. 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."

"Climate engineering (CE) deployment would alter prevailing relationships between Earth system variables, making indicators and metrics used so far in the climate change assessment context less appropriate to assess CE measures. Achieving a comprehensive CE assessment requires a systematic and transparent reevaluation of the indicator selection process from Earth system variables. Here, we provide a first step towards such a systematic assessment of changes in correlations between Earth system variables following simulated deployment of different CE methods."

"Climate litigation has attracted renewed interest as a governance tool. A key challenge in climate litigation is to assess the factual basis of causation. Extreme weather attribution, specifically the Fraction of Attributable Risk (FAR), has been proposed as a way to tackle this challenge. What remains unclear is how attribution science interacts with the legal admissibility of evidence based on climate models. "
