Environmental Health News: Reader response: Opponents of geoengineering misunderstand humanity’s choices
“”Without some kind of prompt geoengineering action, climate change will accelerate the damage we are already seeing.””
“”Without some kind of prompt geoengineering action, climate change will accelerate the damage we are already seeing.””
“Canadian climate policy has yet to address solar geoengineering, but the government acknowledges the need to understand the implications of these hypothesized technologies.”
“Research into unproven technofixes isn’t a replacement for eliminating emissions, even if the debate over geoengineering is stuck on that concern.”

In Inorganica Chimica Acta 518, p. 120256. DOI: 10.1016/j.ica.2021.120256.
“The removal of CO2 from the atmosphere (DAC technology) has been accomplished at room temperature and pressure with aqueous solutions of 2-(ethylamino)ethanol (EMEA) and 2-(2-aminoethoxy)ethanol (DGA).”

“This perspective highlights three issues. First, the scale of CDR deployment will determine the level of emission mitigation in the energy system and vice versa. Second, CDR will interact with societal priorities beyond climate. Finally, the location of CDR could have implications for the country-level pledges, and emissions trading.”

“Based on expert elicitation involving over 30 individuals with backgrounds across the domains of the United Nations’ Sustainable Development Goals (SDGs), we identify a broad range of potential implications of solar radiation modification for the SDGs.”
“Pengfei Yu is a co-author in this ground breaking paper titled “Toward practical stratospheric aerosol albedo modification: Solar-powered lofting.””
“Another big direct-air-capture plant is moving ahead, but a new study finds we may need to build many more before the economics start to make sense.”
“Carbon removal discussions often start with a bunch of mind-bending numbers: Curbing warming to 1.5°C relies upon removing 100–1000 billion tons (or gigatons, Gt) from the atmosphere over the course of this century, according to the Intergovernmental Panel on Climate Change.”
