Noah McQueen; et al. (2020): Ambient weathering of magnesium oxide for CO 2 removal from air

Noah McQueen; Peter Kelemen; Greg Dipple; Phil Renforth; Jennifer Wilcox (2020): Ambient weathering of magnesium oxide for CO 2 removal from air. In Nat Commun 11. DOI: 10.1038/s41467-020-16510-3.

"Here we detail a land-based enhanced weathering cycle utilizing magnesite (MgCO3) feedstock to repeatedly capture CO2 from the atmosphere. In this process, MgCO3 is calcined, producing caustic magnesia (MgO) and high-purity CO2."

Union of Concerned Scientists (2020): Strengthening Public Input on Solar Geoengineering Research

Union of Concerned Scientists (2020): Strengthening Public Input on Solar Geoengineering Research. What’s needed for decisionmaking on atmospheric experiments. Report.

"Although solar geoengineering would have many uncertain impacts and comes with risks, given the growing severity of climate impacts, they merit closer consideration. And as researchers are beginning to design atmospheric experiments to assess how effective and risky these methods are, informed public debate is needed over whether and how such research should proceed."

Science Daily: Arctic plants may not provide predicted carbon sequestration potential

"The new research considered the impact of a shrubbier Arctic on soil carbon stocks and the overall carbon sequestration potential of these ecosystems. Significantly, it found that some tall shrub communities stimulate recycling of carbon in soils, releasing it back into the atmosphere as carbon dioxide -- meaning that more productive shrubs might not always result in greater carbon sequestration."

Daily Mail: Scheme backed by Dominic Cummings to ‘suck’ excess carbon dioxide from the air and bury it underground gets £100m from the Treasury

"However, a roll out of the technology would be expensive and demand massive amounts of energy - which in itself could be a huge source of CO2 emissions."

Video: Clive Elsworth: Iron Salt Aerosol Presentation

"The presentation will briefly:

  • make the urgent case for Negative Emission Technologies,
  • explain how methane removal is the low hanging fruit,
  • explain how a very diffuse ISA application over a wide area of iron-poor ocean would additionally safely induce a continuous, climate-relevant absorption of CO2."

Barben, Daniel; Matzner, Nils (2020): Anticipatory Governance of Climate Engineering

Barben, Daniel; Matzner, Nils (2020): Anticipatory Governance of Climate Engineering. In Oxford Research Encyclopedias: Geoengineering. DOI: 10.1093/acrefore/9780190228620.013.69.

"This article will discuss notions of anticipatory governance as developed in various institutional contexts concerned with assessing, funding, regulating, or conducting research and innovation. It will explore how notions of anticipatory governance have been transferred to the field of CE, in attempts at either shaping the course of CE-related research and innovation or at critically observing various CE-related governance endeavors by evaluating their capacities in anticipatorily governing research and technology development."
