Cosmos: 6 ways geoengineering could fight climate change
„Some researchers think massive engineering projects might help slow global warming. Other scientists aren’t so sure. Stephen Fleischfresser surveys the top six proposals.“

„More broadly, the controversy illustrated long‐standing arguments about the desirability and feasibility of ocean fertilisation as a geoengineering response to the threat of anthropogenic climate change. Using the HSRC case, this paper reports a novel situated study of public perceptions of geoengineering that combines ethnographic engagement with Q‐methodology.“

„New research suggests an old idea of geoengineering has more merit than long suspected“

„The authors first divide the techniques under consideration between solar radiation management (aerosols in the stratosphere, or greater white surfaces below) and carbon dioxide removal (ocean iron fertilization (OIF) and other forms of carbon capture and sequestration). They detail the analysis required for an environmental impact statement (EIS) under the National Environmental Policy Act (NEPA), the California Environmental Quality Act (CEQA), and a variety of other U.S. statutes and common-law doctrines. „

„In this chapter an overview is given of the proposed climate engineering methods that involve the direct manipulation of marine systems. This includes methods that enhance the ocean’s natural physical, chemical, and biological CO2 sequestration pathways, as well as purely technical ones that either use the ocean as a carbon storage reservoir or alter it’s properties to affect the Earth’s radiation budget.“

„The world’s oceans could play an important role in meeting international climate change targets. ‘Marine geoengineering’ is being proposed to enhance the oceans capacity to sequester emissions and enhance the Earth’s albedo. This article draws on discussions at a recent Marine Geoengineering Symposium held at the University of Tasmania to highlight prominent marine geoengineering proposals and raise questions about the readiness of the international law system to govern further research and implementation of these ideas.“

„This paper describes an opportunistic case study of the 2012 Haida Salmon Restoration Corporation’s ocean fertilization project. Anchored in notions of place and identity, the Haida Salmon Restoration Corporation marks a novel entry point into social research on geoengineering, which enables a more situated engagement with ocean fertilization, in keeping with geographical traditions.“

Harrison, Daniel P. (2017): Global negative emissions capacity of ocean macronutrient fertilization. In Environ. Res. Lett. 12 (3), p.[nbsp]35001. DOI: 10.1088/1748-9326/aa5ef5.
„Utilizing global datasets of oceanographic field measurements, and output from a high resolution global circulation model, the current study provides the first comprehensive assessment of the global potential for carbon sequestration from ocean macronutrient fertilization (OMF). Sufficient excess phosphate exists outside the iron limited surface ocean to support once-off sequestration of up to 3.6 Pg C by fertilization with nitrogen. Ongoing maximum capacity of nitrogen only fertilization is estimated at 0.7 ± 0.4 Pg C yr−1.“

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.“
