Abstract: Weathering and subsequent precipitation of Ca- and Mg-carbonates are the main processes that control the CO2-concentration in the atmosphere. It seems logical, therefore, to use enhanced weathering as a tool to reduce rising CO2-levels. This can be applied as a technology, by reacting captured CO2 with olivine or calcium-silicates in autoclaves. It can also be applied extensively, by spreading fine-powdered olivine on farmland or forestland. Measures to control the CO2-levels of the atmosphere will be adopted more readily if they also serve some broader economic goals. An effective strategy for CO2 control will require many parallel approaches simultaneously.

The Intergenerational Transfer of Solar Radiation Management Capabilities and Atmospheric Carbon Stocks
TL;DR: In this paper, the authors identify three conjectures that constitute potentially rational courses of action for current society, including a ban on the development of solar radiation management (SRM) technologies, and also allow for a novel possibility: if the development is sufficiently cheap, the current generation may for reasons of intergenerational strategy decide not just to develop SRM technologies, but also to abate more than in the absence of SRM.

CHAPTER 3:The Global Potential for Carbon Dioxide Removal
Timothy M. Lenton
- 08 May 2014
TL;DR: In this paper, the global physical potential of different methods of carbon dioxide removal (CDR) from the atmosphere is reviewed and a new categorisation into plant-based, algal-based and alkalinity-based approaches to CDR is proposed.

Ideas and perspectives: Synergies from co-deployment of negative emission technologies
Thorben Amann,Jens Hartmann +1 more
TL;DR: To derive more reliable estimates of negative emission potentials and to evaluate common effects on global carbon pools, it is now necessary to intensively study interrelated effects ofnegative emission technology deployment while minimizing negative side effects.

On the history of humans as geomorphic agents
TL;DR: The human population has been increasing exponentially. as discussed by the authors states that the ability and motivation to modify the landscape by moving earth in construction and mining activities has also increased dramatically, and we have now become arguably the premier geomorphic agent sculpting the landscape, and the rate at which we are moving earth is increasing exponentially, and this constitutes an unintended additional human impact on the landscape.
Sequestration of carbon by soil
TL;DR: In this article, the potential of soil carbon to sequester carbon in the atmosphere is discussed. And the potentials of different types of soil can be reliably predicted based on the characteristics of the soil organic matter and its ability to resist microbial degradation.

Carbonate chemistry for sequestering fossil carbon
TL;DR: Carbon dioxide can be formed from carbon dioxide and metal oxides in reactions that are thermodynamically favored and exothermic, which result in materials that can be safely and permanently kept out of the active carbon stocks in the environment as discussed by the authors.

Experimental determination of the effect of dissolved CO2 on the dissolution kinetics of Mg and Ca silicates at 25 °C
TL;DR: In this paper, the authors measured dissolution rates of diopside, forsterite (Fo100 and Fo92), wollastonite, and hornblende in NaCl solutions as a function of pH (1≤pH≤12), pCO2 (0 and 1 atm) and activity of HCO3− and CO32− (10−5≤∑CO2≤0.1 M).
