Stenzel, Fabian, et al. (2021): Global scenarios of irrigation water abstractions for bioenergy production: a systematic review

Stenzel, Fabian; Gerten, Dieter; Hanasaki, Naota (2021): Global scenarios of irrigation water abstractions for bioenergy production: a systematic review. In Hydrol. Earth Syst. Sci. 25 (4), pp. 1711–1726. DOI: 10.5194/hess-25-1711-2021.

"This paper reviews existing global assessments of freshwater abstractions for bioenergy production and puts these estimates into the context of scenarios of other water-use sectors."

van Soest, Heleen L.; et al. (2021): Net-zero emission targets for major emitting countries consistent with the Paris Agreement

van Soest, Heleen L.; Elzen, Michel G. J. den; van Vuuren, Detlef P. (2021): Net-zero emission targets for major emitting countries consistent with the Paris Agreement. In Nat Comms 12 (1), p. 2140. DOI: 10.1038/s41467-021-22294-x.

"Here, we look at national-level neutrality-years based on globally cost-effective 1.5 °C and 2 °C scenarios from integrated assessment models. These results indicate that domestic net zero greenhouse gas and CO2 emissions in Brazil and the USA are reached a decade earlier than the global average, and in India and Indonesia later than global average."

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."

Full, Johannes; et al. (2021): A New Perspective for Climate Change Mitigation—Introducing Carbon-Negative Hydrogen Production from Biomass with Carbon Capture and Storage (HyBECCS)

Full, Johannes; Merseburg, Steffen; Miehe, Robert; Sauer, Alexander (2021): A New Perspective for Climate Change Mitigation—Introducing Carbon-Negative Hydrogen Production from Biomass with Carbon Capture and Storage (HyBECCS). In Sustainability 13 (7), p. 4026. DOI: 10.3390/su13074026.

"This paper introduces for the first time a novel concept for the production of hydrogen with net negative emissions. The derived concept combines biohydrogen production using biotechnological or thermochemical processes with carbon dioxide (CO2) capture and storage."

Zarnetske, Phoebe L.; et al. (2021): Potential ecological impacts of climate intervention by reflecting sunlight to cool Earth

Zarnetske, Phoebe L.; Gurevitch, Jessica; Franklin, Janet; Groffman, Peter M.; Harrison, Cheryl S.; Hellmann, Jessica J. et al. (2021): Potential ecological impacts of climate intervention by reflecting sunlight to cool Earth. In PNAS 118 (15), e1921854118. DOI: 10.1073/pnas.1921854118.

"We focus here on stratospheric aerosol intervention (SAI), a well-studied and relatively feasible SRM scheme that is likely to have a large impact on Earth’s surface temperature. We outline current gaps in knowledge about both helpful and harmful predicted effects of SAI on ecological systems."
