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."

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."
