Simon, Balint (2021): Material flows and Embodied Energy of Direct Air Capture

Simon, Balint (2021): Material flows and Embodied Energy of Direct Air Capture. In: Chemical Engineering and Industrial Chemistry. DOI: 10.33774/chemrxiv-2021-bpg5d.

"Direct air capture (DAC) is an essential nexus of CO2 chemistry and climate mitigation. Life cycle assessment (LCA) is often deployed to validate the environmental potentials of such future emerging technologies [...] the present paper analyses three selected DAC technologies to create an inventory for LCAs. Amine-based adsorption and -absorption, as well as, alkali-based absorption was modelled."

McAfee, Kathleen (2021): Shall the American Association of Geographers Endorse Carbon Offsets? Absolutely Not!

McAfee, Kathleen (2021): Shall the American Association of Geographers Endorse Carbon Offsets? Absolutely Not! In The Professional Geographer, pp. 1–7. DOI: 10.1080/00330124.2021.1934879.

"The American Association of Geographers should not contribute to this illusion by endorsing offsetting. Instead we should take steps to reduce our own emissions and speak out clearly when our work has bearing on policy decisions and public perceptions about the climate crisis."

Woodhouse, Elliott (2021): Cooling the Planet Without Hot Takes

Woodhouse, Elliott (2021): Cooling the Planet Without Hot Takes. In Capitalism Nature Socialism, pp. 1–3. DOI: 10.1080/10455752.2021.1959857.

"Has it Come to This? tries to take a step back from all the hot takes. It showcases perspectives from scholars who begin by saying that as strange as it may look on the surface, geoengineering is something we know and that we can understand with the tools we already have."

Young, John; et al. (2021): The impact of binary water–CO2 isotherm models on the optimal performance of sorbent-based direct air capture processes

Young, John; García-Díez, Enrique; Garcia, Susana; van der Spek, Mijndert (2021): The impact of binary water–CO 2 isotherm models on the optimal performance of sorbent-based direct air capture processes. In Energy & Environmental Science. DOI: 10.1039/D1EE01272J.

"We present two novel mechanistic co-adsorption isotherm models to describe water's effect on CO2 adsorption and find a good fit to original experimental co-adsorption data. We also show the considerable improvement in predictions of these models when compared to an empirical co-adsorption isotherm model from literature."

Renforth, P.; Campbell, J. S. (2021): The role of soils in the regulation of ocean acidification

Renforth, P.; Campbell, J. S. (2021): The role of soils in the regulation of ocean acidification. In Philosophical transactions of the Royal Society of London. Series B, Biological sciences 376 (1834), p. 20200174. DOI: 10.1098/rstb.2020.0174.

"Increasing the alkalinity levels in the ocean through enhanced weathering could help to ameliorate the effects of ocean acidification in two ways. First, enhanced weathering would slightly elevate the pH of drainage waters, and the receiving coastal waters. The elevated pH would result in an increase in carbonate mineral saturation states, and a partial reversal in the effects of elevated CO2. Second, the increase in alkalinity would help to replenish the ocean's buffering capacity by maintaining the ‘Revelle Factor’, making the oceans more resilient to further CO2 emissions. However, there is limited research on the downstream and oceanic impacts of enhanced weathering on which to base deployment decisions."

Fleming, James Rodger (2021): Excuse Us, While We Fix the Sky: WEIRD Supermen and Climate Intervention

Fleming, J.R. (2021): Excuse Us, While We Fix the Sky: WEIRD Supermen and Climate Intervention. In: Pulé P.M., Hultman M. (eds) Men, Masculinities, and Earth. Palgrave Studies in the History of Science and Technology. Palgrave Macmillan, Cham. https://doi.org/10.1007/978-3-030-54486-7_24

"As alarm over global warming spreads, a radical idea is taking hold. An emerging breed of so-called climate engineers is promoting invasive techniques to cool the planet through albedo modification and so-called “negative carbon emissions” will be necessary. While these proposals seem edgy and exciting, they often test the limits of scientific, technological, and institutional possibility and overlook the political, ethical, and social consequences of managing the world’s climate. Advocates of climate engineering, with vanishingly few exceptions, are Western, Educated, Industrialized, Rich, and Democratic (WEIRD) males with superman complexes. Their views are short-sighted, dangerous, and “barking mad.” This chapter provides historical perspectives, social context, and a gendered analysis of these dangerous proposals."

Yue, Chao; et al. (2021): Vatnajökull mass loss under solar geoengineering due to the North Atlantic meridional overturning circulation

Yue, Chao; Schmidt, Louise Steffensen; Zhao, Liyun; Wolovick, Michael; Moore, John C. (2021): Vatnajökull mass loss under solar geoengineering due to the North Atlantic meridional overturning circulation. In Earth’s Future. DOI: 10.1029/2021EF002052.

"The objective of solar geoengineering by stratospheric aerosol injection (SAI) is to lower global temperatures, but it may also have adverse side-effects. Iceland is situated close to the overturning regions of the Atlantic Meridional Overturning Circulation (AMOC) that warms the North Atlantic area. Hence this may be one region where reduced irradiance by SAI may not be successful in reducing impacts from greenhouse gas warming. We examine this proposition by estimating how the Icelandic Vatnajökull ice cap (VIC) surface mass balance (SMB) and surface runoff changes in response to greenhouse gas and solar geoengineering scenarios over the period 1982-2089."

Miller, Leonard A.; Orton, Philip M. (2021): Achieving negative emissions through oceanic sequestration of vegetation carbon as Black Pellets

Miller, Leonard A.; Orton, Philip M. (2021): Achieving negative emissions through oceanic sequestration of vegetation carbon as Black Pellets. In Climatic Change 167 (3-4), pp. 1–23. DOI: 10.1007/s10584-021-03170-5.

"If confirmed by research, OSB would be an addition to the sparse toolbox of negative emission technologies (NETs) which would give humankind more flexibility in meeting the goals of the Paris Agreement."

Lee, Kaylin Soo Bin; et al. (2021): Fair distributions of carbon dioxide removal obligations and implications for effective national net-zero targets

Lee, Kaylin Soo Bin; Fyson, Claire; Schleussner, Carl-Friedrich (2021): Fair distributions of carbon dioxide removal obligations and implications for effective national net-zero targets. In Environ. Res. Lett. DOI: 10.1088/1748-9326/ac1970.

"Here we show that, depending on the normative assumptions underlying a CDR burden-sharing system, the adjusted net-zero date for big emitting countries could shift forward by up to 15 years (EU, based on per capita GDP) to 35 years (Russia, based on cumulative per capita emissions) compared with what is modeled domestically in global least-cost scenarios."
