Phys.org: Ocean geoengineering tests violate UN convention: green groups

"Experimental geoengineering schemes to protect areas such as Australia's Great Barrier Reef are "distracting technofixes" that violate an international moratorium on the largely untested tech projects, a coalition of nearly 200 environmental groups said Monday."

Project: Ocean-Climate Trust

"The Ocean-Climate Trust is working to define and mobilize a more comprehensive approach to arresting climate disruption, and to unlock new resources for negative emissions and ecosystem life support elements of the portfolio, with particular focus on the ocean contributions to each."

Chemistry World: Ocean motion turns carbon dioxide into renewable fuel

"Scientists have achieved a first in harvesting energy from water waves to make a carbon-based liquid fuel. By generating static electricity from the undulating motion, they are able to convert carbon dioxide into the hydrogen-carrier formic acid."

Earth & Space News: Anaerobic Activity Is a Big Contributor in Marine “Dead Zones”

"Certain parts of Earth’s oceans are so oxygen depleted that they can hardly sustain life. Climate models predict that these “dead zones” will expand as global warming progresses, affecting ecosystems, fisheries, and the climate itself. Now Lengger et al. provide new evidence that such predictions do not adequately account for the activity of anaerobic microbes that consume inorganic carbon within dead zones."

Liu, Yi; et al. (2020): Multicentury Climate Warming Slows Meridional Overturning Circulation, Sequestering Nutrients in the Deep Ocean and Reducing Uptake of Anthropogenic CO2

Liu, Yi, Jefferson Keith Moore, and Francois W. Primeau (2020): Multicentury Climate Warming Slows Meridional Overturning Circulation, Sequestering Nutrients in the Deep Ocean and Reducing Uptake of Anthropogenic CO2. Earth and Space Science Open Archive. January 4, 2020. https://www.essoar.org/doi/10.1002/essoar.10501562.1.

"This Community Earth System Model (CESM) simulation did not include active ice sheet dynamics, but the strong climate warming simulated would lead to large freshwater discharge from the Antarctic and Greenland ice sheets. This would further stratify the polar regions, potentially leading to complete shutdown of the meridional overturning circulation. The impacts of this would be catastrophic as the hothouse Earth climate conditions could be extended for thousands of years, with widespread ocean anoxia developing, driving a mass extinction event."

Lannoy, Charles-Francois de; et al. (2017): Indirect ocean capture of atmospheric CO2. Part I. Prototype of a negative emissions technology

Lannoy, Charles-Francois de; Eisaman, Matthew D.; Jose, Arun; Karnitz, Stephen D.; DeVaul, Richard W.; Hannun, Kathy; Rivest, Jessy L.B. (2017): Indirect ocean capture of atmospheric CO 2. Part I. Prototype of a negative emissions technology. In International Journal of Greenhouse Gas Control. DOI: 10.1016/j.ijggc.2017.10.007.

"We present the design, construction, characterization, and analysis of a prototype process for a novel electrochemical platform of candidate negative emissions technologies (NETs), termed indirect ocean capture. The IOC technologies remove carbon dioxide gas from the atmosphere by leveraging both air-ocean gas exchange and the pH sensitivity of the ocean’s carbonate buffer system. The system characterized in this paper enables two configurations that capture CO2 either as a pure gas or as a solid mineral."

Russ George Blog: First ever major UN Oceans Conference is underway though it is about oceans in spin only

"The key goal of the ocean conference blatantly leaves out vital ocean restoration.Someone must speak for the oceans that need our help to restore them to historic health and abundance."
