The Science Times: Solar Geoengineering To Stop Global Warming

"Harvard scientists believe that the only way to put a curb on the effects of global warming is to keep the sun's heat from entering the Earth. How do you do this? The process of solar geotechnics, as well as solar geoengineering, will help keep the Earth cooler as scientists look for more ways to help save it."

Earther: The U.S. Wants to Keep the UN in the Dark About Geoengineering Efforts

"In the pantheon of climate change solutions, some are more fraught than others. Reducing carbon emissions? Not so risky. Blocking the sun or banking on sucking carbon out of the air? Pretty dicey."

Viglizzo, E. F.; et al. (2019): Reassessing the role of grazing lands in carbon-balance estimations. Meta-analysis and review

Viglizzo, E. F.; Ricard, M. F.; Taboada, M. A.; Vázquez-Amábile, G. (2019): Reassessing the role of grazing lands in carbon-balance estimations. Meta-analysis and review. In: The Science of the Total Environment 661, S. 531–542. DOI: 10.1016/j.scitotenv.2019.01.130.

"Assuming a steady state between carbon (C) gains and losses, greenhouse gases (GHG) inventories that follow a widely used simplified procedure (IPCC Tier 1) tend to underestimate the capacity of soils in grazing-land to sequester C. In this study we compared the C balance reported by (i) national inventories that followed the simplified method (Tier 1) of IPCC (1996/2006), with (ii) an alternative estimation derived from the meta-analysis of science-based, peer-reviewed data."

Axios: Carbon removal tech is having a moment

"Silicon Valley startup accelerator Y Combinator has thrust carbon removal startups into the spotlight, amid growing concerns over climate change. Why it matters: Venture capital's natural appetite for funding moonshots could make it a positive force — if it overcome disappointments from last decade's failed cleantech investments."

Fasihi, M.; et al. (2019): Techno-economic assessment of CO2 direct air capture plants

Fasihi, M.; Efimova, O.; Breyer, C. (2019): Techno-economic assessment of CO2 direct air capture plants. In: Journal of Cleaner Production. DOI: 10.1016/j.jclepro.2019.03.086.

"CO2 direct air capture (DAC) has been increasingly discussed as a climate change mitigation option. Despite technical advances in the past decade, there are still misconceptions about DAC's current and long-term costs as well as energy, water and area demands. This could undermine DAC's anticipated role in a neutral or negative greenhouse gas emission energy system, and influence policy makers. In this study, a literature review and techno-economic analyses of state-of-the-art DAC technologies are performed, wherein, DAC technologies are categorised as high temperature aqueous solutions (HT DAC) and low temperature solid sorbent (LT DAC) systems, from an energy system perspective."

Call for Abstracts: CLIMATE LAW SPECIAL ISSUE WITH ASSOCIATED WORKSHOP

Deadline: 30. April 2019

"A special issue of the journal Climate Law on the role of international and domestic law in research and potential deployment of carbon dioxide removal (CDR) options is planned for late 2020. Original papers will be considered, not limited to the following topics pertinent to carbon dioxide removal approaches: The role of the Paris Agreement; The relevance of customary international law; The potential role of human rights regimes; Regulation of marine-based CDR options; The relevance of international procedural regimes, including the Espoo and Aarhus Conventions; Potentially pertinent domestic regulatory frameworks, especially those with comparative law relevance;"
