Costa, K. M.; et al. (2016): No iron fertilization in the equatorial Pacific Ocean during the last ice age

Costa, K. M.; McManus, J. F.; Anderson, R. F.; Ren, H.; Sigman, D. M.; Winckler, G. et al. (2016): No iron fertilization in the equatorial Pacific Ocean during the last ice age. In Nature 529 (7587), pp. 519–522. DOI 10.1038/nature16453.

"Here we present meridional transects of dust (derived from the 232Th proxy), phytoplankton productivity (using opal, 231Pa/230Th and excess Ba), and the degree of nitrate consumption (using foraminifera-bound δ15N) from six cores in the central equatorial Pacific for the Holocene (0–10,000 years ago) and the LGP (17,000–27,000 years ago). We find that, although dust deposition in the central equatorial Pacific was two to three times greater in the LGP than in the Holocene, productivity was the same or lower, and the degree of nitrate consumption was the same. These biogeochemical findings suggest that the relatively greater ice-age dust fluxes were not large enough to provide substantial iron fertilization to the central equatorial Pacific."

Asia One: Shivers over growing plankton to cool earth

"Fertilising the seas to create a plankton bloom may sound like a bad idea, as these mounds of microalgae have caused mass fish deaths in Singapore and around the world. But some scientists believe it will help reduce carbon dioxide, a greenhouse gas, and combat global warming."

Dotto, Lucas; Pelkey, Bryan (2015): Assessing Scientific Legitimacy. The Case of Marine Geoengineering

Dotto, Lucas; Pelkey, Bryan (2015): Assessing Scientific Legitimacy. The Case of Marine Geoengineering (CIGI Graduate Fellows Policy Brief, 10).

"Gaps in the governance of this scientific research still remain. To remedy these issues, this brief recommends that the International Maritime Organization and parties to the LC-LP develop memorandums of understanding to delineate framework implementation plans, adopt legally binding governance transparency mechanisms to ensure linkages between national and international governance institutions, and create independent assessment panels."

Zhang, Yanzhu; Posch, Alfred (2014): The Wickedness and Complexity of Decision Making in Geoengineering

Zhang, Yanzhu; Posch, Alfred (2014): The Wickedness and Complexity of Decision Making in Geoengineering. In Challenges 5 (2), pp. 390–408. DOI 10.3390/challe5020390.

"The intertwined sociotechnical complexity and conflicting attitudes make geoengineering a wicked and complex issue. This article elaborates the wickedness and complexity from a system perspective, primarily for an interdisciplinary, policy-oriented audience."

Environmental Research Web: ‘Moderate’ geoengineering could help temperature in all areas

Article presenting the study Kravitz, Ben; et al. (2014). "A new study shows that if only moderate solar geoengineering was deployed everyone would gain something, with all regions of the world benefiting from lower temperatures than those predicted for a high-carbon dioxide scenario without such action."
