The New Political: OPINION: Democrats Discuss — Geoengineering: Hail Mary or heresy?

"In the absence of action from governments, some scientists and leaders are researching and proposing the route of geoengineering. Geoengineering is not a new subject, but it has become increasingly present in climate and scientific circles."

Lee, Walker Raymond; et al. (2021): High‐latitude stratospheric aerosol geoengineering can be more effective if injection is limited to spring

Lee, Walker Raymond; MacMartin, Douglas G.; Visioni, Daniele; Kravitz, Ben (2021): High‐latitude stratospheric aerosol geoengineering can be more effective if injection is limited to spring. In Geophysical Research Letters. DOI: 10.1029/2021GL092696.

"We demonstrate that spring injection produces approximately twice as much summer AOD as year‐round injection and restores approximately twice as much September sea ice, resulting in less increase in stratospheric sulfur burden, stratospheric heating, and stratospheric ozone depletion per unit of sea ice restored. We also find that differences in AOD between different seasonal injection strategies are small compared to the difference between annual and spring injection."

Wang, Yushan; et al. (2021): Carbon Dioxide Capture by Non-aqueous Blend in Rotating Packed Bed Reactor: Absorption and Desorption Investigation

Wang, Yushan; Dong, Yuning; Zhang, Liangliang; Chu, Guangwen; Zou, Haikui; Sun, Baochang; Zeng, Xiaofei (2021): Carbon Dioxide Capture by Non-aqueous Blend in Rotating Packed Bed Reactor: Absorption and Desorption Investigation. In Separation and Purification Technology, p. 118714. DOI: 10.1016/j.seppur.2021.118714.

"In this work, 2-amino-2-methyl-1-propanol (AMP), 2-(2-aminoethylamino)ethanol (AEEA), N-methyl pyrrolidone (NMP) tri-solvent blend is used as a novel non-aqueous absorbent for CO2 capture process in rotating packed bed (RPB) reactor, which is employed to intensify the mass transfer in both absorption and desorption process."

Paulo, Carlos; et al. (2021): Evaluating feedstocks for carbon dioxide removal by enhanced rock weathering and CO2 mineralization

Paulo, Carlos; Power, Ian M.; Stubbs, Amanda R.; Wang, Baolin; Zeyen, Nina; Wilson, Siobhan A. (2021): Evaluating feedstocks for carbon dioxide removal by enhanced rock weathering and CO2 mineralization. In Applied Geochemistry, p. 104955. DOI: 10.1016/j.apgeochem.2021.104955.

"We have developed a new method to evaluate the reactivity of mineral feedstocks that consists of a batch leach test using CO2 coupled with total inorganic carbon (TIC) analysis to quantify easily extractable Mg and Ca from non-carbonate (desirable) cation sources."

Statesman Journal: Carbon dioxide removal every bit as key

"Oregon has long been a leader in advancing climate policies. But we need to accelerate and expand that work – for our state and the nation. To fight climate change and grow our economy, we should increase federal investments and create stronger incentives for climate solutions like carbon dioxide removal and carbon storage."
