„Most efforts at combating climate change have focused on reducing carbon emissions or trying to eliminate them, but many climate scientists believe we may have already passed the point of no return. That’s why Noah Deich wants to pull carbon out of the air.“
„Spraying billions of dollars worth of diamond particles into the atmosphere could be an effective method of combating global warming, according to an analysis by climate scientists“

„This creativity is always new and always unique, and there is no repetition to it:[nbsp]each society establishes a unique imaginary world and there is no articulation of a society that is given once and for all. However, modern societies have a tendency to think of technê as if it were nature – something that always occures in the same way. This misreading is what leaves modern societies unable to account for creative technê, and insensitive to different articulations of worlds.“

„We present a suite of new climate model experiment designs for the Geoengineering Model Intercomparison Project (GeoMIP). This set of experiments, named GeoMIP6 (to be consistent with the Coupled Model Intercomparison Project Phase 6), builds on the previous GeoMIP project simulations, and has been expanded to address several further important topics, including key uncertainties in extreme events, the use of geoengineering as part of a portfolio of responses to climate change, and the relatively new idea of cirrus cloud thinning to allow more longwave radiation to escape to space.„

„To examine the impact of proposed stratospheric geoengineering schemes on the amplitude and frequency of El Niño/Southern Oscillation (ENSO) variations we examine climate model simulations from the Geoengineering Model Intercomparison Project (GeoMIP) G1–G4 experiments. Here we compare tropical Pacific behavior under anthropogenic global warming (AGW) using several scenarios: an instantaneous quadrupling of the atmosphere’s CO2 concentration, a 1 % annual increase in CO2 concentration, and the representative concentration pathway resulting in 4.5 W m−2 radiative forcing at the end of the 21st century, the Representative Concentration Pathway 4.5 scenario, with that under G1–G4 and under historical model simulations.„
Response to Weisenstein, D. K.; et al. (2015). „Solid particles of diamond or alumina might be safer than sulphate droplets as a way to redirect the Sun’s energy, calculations suggest.“

„We use a two-dimensional (2-D) chemistry–transport–aerosol model to capture the dynamics of interacting solid and liquid aerosols in the stratosphere. […] Our results suggest that appropriately sized alumina, diamond or similar high-index particles may have less severe technology-specific risks than sulfate aerosols do. These results, particularly the ozone response, are subject to large uncertainties due to the limited data on the rate constants of reactions on the dry surfaces.„
„One way to keep global average temperatures from warming beyond a catastrophic 2-degree-celsius tipping point, according to some experts, is to suck massive amounts of CO2 out of the atmosphere.“
„In a Yale Environment 360 interview, Australian scientist and author Tim Flannery explains how the development of technologies that mimic the earth’s natural carbon-removing processes could provide a critical tool for slowing global warming. „

„We estimate that stratospheric sulfate aerosol geoengineering may somewhat ameliorate Atlantic hurricane intensity and frequency, but there will be more “Katrina”-level events than during the past 30 y. Geoengineering would likely be reasonably effective at controlling coastal flood risk relative to the coastal flood risk expected under the Representative Concentration Pathway (RCP) 4.5 greenhouse gas warming, in part, due to its impact on global sea level rise, although flood risk would still be significantly larger than at present.“
