Lauderdale, Jonathan Maitland; et al. (2020): Microbial feedbacks optimize ocean iron availability

Lauderdale, Jonathan Maitland; Braakman, Rogier; Forget, Gaël; Dutkiewicz, Stephanie; Follows, Michael J. (2020): Microbial feedbacks optimize ocean iron availability. In Proceedings of the National Academy of Sciences of the United States of America. DOI: 10.1073/pnas.1917277117.

"Dissolved iron is quickly lost from the ocean, but its availability to marine microbes may be enhanced by binding with organic molecules which, in turn, are produced by microbes. We hypothesize this forms a reinforcing cycle between biological activity and iron cycling that locally matches the availability of iron and other nutrients, leading to global-scale resource colimitation between macronutrients and micronutrients, and maximizing biological productivity."

European Scientist: Fertilising the ocean with iron might not work, a new study suggests

"The benefits of adding more iron to the oceans — known as iron fertilisation — would be limited, at least on a global scale, according to a new study published in the 18 February 2020 issue of the Proceedings of the National Academy of Sciences (1). In other words, there is ‘just enough’ iron in the ocean."

Ocean Carbon Dioxide Removal Knowledge Hub

"This forthcoming Knowledge Hub aims to bring together stakeholders from science, policy, and the private sector to identify and close knowledge gaps, share questions and insights, form new partnerships, and create a common understanding of viable pathways by which the ocean can help solve the climate crisis.

This Knowledge Hub will include a searchable discussion forum, a curated document database, and broad networking functionalities."

Expert Group of the International Military Council on Climate and Security: The World Climate and Security Report 2020

“The World Climate and Security Report 2020.” Product of the Expert Group of the International Military Council on Climate and Security. Authors: Steve Brock (CCS), Bastien Alex (IRIS), Oliver-Leighton Barrett (CCS), Francesco Femia (CCS), Shiloh Fetzek (CCS), Sherri Goodman (CCS), Deborah Loomis (CCS), Tom Middendorp (Clingendael), Michel Rademaker (HCSS), Louise van Schaik (Clingendael), Julia Tasse (IRIS), Caitlin Werrell (CCS). Edited by Francesco Femia & Caitlin Werrell. Published by the Center for Climate and Security, an institute of the Council on Strategic Risks. Feb 2020.

"Climate mitigation, adaptation  and resilience efforts are increasingly urgent to avert the significant security consequences of climate change, yet some proposed solutions such as geoengineering could present  negative second-order effects to global security, if not implemented carefully."

The Breakthrough Institute: Building Bridges to Negative Emissions

"Natural carbon sequestration, including large-scale reforestation, is a more promising option, but it would only replace the carbon released when those forests were first cut down — it won't be enough to substantially reduce future warming."
