Montserrat, Francesc; et al. (2017): Olivine Dissolution in Seawater: Implications for CO2 Sequestration through Enhanced Weathering in Coastal Environments

Montserrat, Francesc; Renforth, Phil; Hartmann, Jens; Leermakers, Martine; Knops, Pol; Meysman, Filip J. R. (2017): Olivine Dissolution in Seawater: Implications for CO2 Sequestration through Enhanced Weathering in Coastal Environments. In Environ. Sci. Technol. DOI: 10.1021/acs.est.6b05942.

„Here, we present results from batch reaction experiments, in which forsteritic olivine was subjected to rotational agitation in different seawater media for periods of days to months. Olivine dissolution caused a significant increase in alkalinity of the seawater with a consequent DIC increase due to CO2 invasion, thus confirming viability of the basic concept of enhanced silicate weathering.“

New Blog: OLIVOA (Enhanced Olivine Weathering)

„OLIvOA is a research initiative investigating the use of enhanced weathering of the silicate mineral olivine against Ocean Acidification. Olivine weathering causes the seawater to become less acidic and increases its capacity to take up (more) carbon dioxide (CO2). OLIvOA ‚headquarters‘ is currently located in Brazil, but collaborates with researchers from all over the world. The epicenter of OLIvOA research is (still) in Europe.“

Rockström, Johan; et al. (2017): A roadmap for rapid decarbonization

Rockström, Johan; Gaffney, Owen; Rogelj, Joeri; Meinshausen, Malte; Nakicenovic, Nebojsa; Schellnhuber, Hans Joachim (2017): A roadmap for rapid decarbonization. In Science 355 (6331), pp.[nbsp]1269–1271. DOI: 10.1126/science.aah3443.

Including negative emissions/BECCS. „Complemented by immediately instigated, scalable carbon removal and efforts to ramp down land-use CO2 emissions, this can lead to net-zero emissions around mid-century, a path necessary to limit warming to well below 2°C.“

Visioni, Daniele; et al. (2017): Sulfate geoengineering. A review of the factors controlling the needed injection of sulfur dioxide

Visioni, Daniele; Pitari, Giovanni; Aquila, Valentina (2017): Sulfate geoengineering. A review of the factors controlling the needed injection of sulfur dioxide. In Atmos. Chem. Phys 17 (6), pp.[nbsp]3879–3889. DOI: 10.5194/acp-17-3879-2017.

„A review of previous studies on these effects is presented here, with an outline of the important factors that control the amount of sulfur dioxide to be injected in an eventual realization of the experiment. However, we need to take into account that atmospheric models used for these studies have shown a wide range of climate sensitivity and differences in the response to stratospheric volcanic aerosols. In addition, large uncertainties exist in the estimate of some of these aerosol effects.„

San Diego Union-Tribune: Climate change: Trump’s dramatic move deserves dramatic response

„Another Union-Tribune op-ed by Jane C.S. Long — until recently the associate director for energy and environment at Lawrence Livermore National Laboratory — outlines a plausible approach to taking on global warming that doesn’t require Trump’s approval. Long strongly supports conventional attempts to reduce greenhouse-gas emissions. But she notes that even if all emissions stopped immediately, “mankind has already ‘bought’ a thousand years of climate change.”“
