Inhabitant: Risky geoengineering research deemed safe, blocked by US

„Geoengineering is a term used for a collection of technologies to artificially alter the earth’s climate. Other climate engineering technologies include ocean fertilization, carbon dioxide removal, marine cloud brightening, cirrus cloud thinning[nbsp]and ground-based albedo modification. These strategies are incredibly controversial both because of the unprecedented and unknown risks at a global scale, but also for ethical reasons of how humans should intervene in the earth’s climate.“


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.“


Carbon Engineering: Carbon Engineering concludes USD$68 million private investment round and proceeds with commercialization of carbon dioxide removal technology

„Carbon Engineering Ltd. (CE), a Canadian clean energy company, today announced the completion of an equity financing round of USD$68 million, marking the largest private investment made into a Direct Air Capture (DAC) company to date. With multiple investors now on board, this financing highlights the significant commercial interest in DAC, particularly from the global energy and private investment sectors.“
