Yuan, Peng; Liu, Dong (2021): Proposing a potential strategy concerning Mineral-enhanced Biological Pump (MeBP) for improving Ocean Iron Fertilization (OIF)

Yuan, Peng; Liu, Dong (2021): Proposing a potential strategy concerning Mineral-enhanced Biological Pump (MeBP) for improving Ocean Iron Fertilization (OIF). In Applied Clay Science 207, p. 106096. DOI: 10.1016/j.clay.2021.106096.

"To address the low efficiency of the vertical C export of OIF, a potential strategy for enhancing oceanic biological pump using clay minerals, so-called mineral-enhanced biological pump (MeBP), is proposed herein."

Ming, Tingzhen; et al. (2021): A nature-based negative emissions technology able to remove atmospheric methane and other greenhouse gases

Ming, Tingzhen; Richter, Renaud de; Dietrich Oeste, Franz; Tulip, Robert; Caillol, Sylvain (2021): A nature-based negative emissions technology able to remove atmospheric methane and other greenhouse gases. In Atmospheric Pollution Research. DOI: 10.1016/j.apr.2021.02.017.

"As some anthropogenic emissions cannot be zero, to compensate them it will be necessary to remove GHGs from the atmosphere. Among possible methods, the Iron Salt Aerosol (ISA) offers new possibilities, including removal of methane and several other GHGs, as well as carbon dioxide."

Rohr, T. (2019): Southern Ocean Iron Fertilization: An Argument Against Commercialization but for Continued Research Amidst Lingering Uncertainty

Rohr, Tyler (2019): "Southern Ocean Iron Fertilization: An Argument Against Commercialization but for Continued Research Amidst Lingering Uncertainty". Journal of Science Policy & Governance, Vol. 15, October 2019.

"I make that case that absent the appropriate oversight OIF activity on voluntary offset markets motivated by a reasonable market opportunity, the relative ease of deployment, and the perception of an ethical imperative, can, and will continue to, emerge. In turn, I argue that continued research is necessary to help constrain the public perception that voluntary markets depend on by further clarifying the risks, elaborating the challenges, and delegitimizing the promise of an iron bullet."

Gambardella, S. (2019): The Stormy Emergence of Geoengineering in the International Law of the Sea

Gambardella, S. 2019. “The Stormy Emergence of Geoengineering in the International Law of the Sea.” Carbon & Climate Law Review 13 (2): 122–29. https://doi.org/10.21552/cclr/2019/2/7.

‌"This study aims to look at the role that international environmental law could or should play in the development of geoengineering. The discussions that have taken place on geoengineering in international fora are rich in lessons about these rights themselves and with regard to their effectiveness and efficiency. Thus, questions of ‘good governance’ emerge. It is therefore a question of presenting the various possibilities offered by international law to frame - even forbid - these new practices."

Fiekowsky, Peter; et al. (2019): Climate Restoration: Solutions to the Greatest Threat Facing Humanity and Nature Today. The Foundation for Climate Restoration, September 2019. White Paper.

Fiekowsky, Peter; Douglis, Carole; Lee, Susan (2019): Climate Restoration: Solutions to the Greatest Threat Facing Humanity and Nature Today. The Foundation for Climate Restoration, September 2019. White Paper. Available online at https://foundationforclimaterestoration.org/wp-content/uploads/2019/09/20190916b_f4cr4_white-paper.pdf.

"The purpose of this paper is to show that we do not in fact need to leave dangerous, unprecedented conditions to our progeny. We have the technology and the financing, now, to reclaim the climate of over a century ago. What we need is the commitment to do so."

Pan, YiWen; et al. (2019): A sea trial of air-lift concept artificial upwelling in the East China Sea

Pan, YiWen; Li, Yifan; Fan, Wei; Zhang, DaHai; Qiang, Yongfa; Jiang, ZongPei; Chen, Ying (2019): A sea trial of air-lift concept artificial upwelling in the East China Sea. In: Journal of Atmospheric and Oceanic Technology. DOI: 10.1175/JTECH-D-18-0238.1.

"In this work, a sea-trial of an air-lift concept AU system driven by self-powered energy was carried out in the East China Sea (ECS) (30°8′14″N, 122°44′59″E) to assess the logistics of at-sea deployment and the durability of the equipment under extremely complex hydrodynamic condition from Sep 3rd to 7th, 2014."

Anthropocene: While we debate geoengineering the ocean, it seems we’re already doing it

"Researchers in the United States analyzed iron in air samples collected on a research cruise in the North Atlantic Ocean. They used stable isotopes—forms of the same chemical element with different atomic weights—to discern the signature of different sources of iron."
