Eco: This is Not a Drill: Geoengineering is on the Rise

"ECO recalls that in addition to ethical concerns about manipulating the Earth’s thermostat, SRM does not reduce GHG emissions, air pollution, or marine acidification; and it could undermine sustainable development goals. Furthermore, if SRM deployment were to begin on a significant scale it would be hard to stop, since its postulated effects of cooling are not permanent and it could trigger resurgent global warming if greenhouse gas concentrations continue to rise or remain at historically high levels."

Science Daily: Huge carbon sink in soil minerals: New avenue for offsetting rising greenhouse gases

"Soil holds more than three times the carbon found in the atmosphere, yet its potential in reducing atmospheric carbon-dioxide levels and mitigating global warming is barely understood. A researcher has discovered that vast amounts of carbon can be stored by soil minerals more than a foot below the surface. The finding could help offset the rising greenhouse-gas emissions helping warm the Earth's climate. "

Warren Centre: Geoengineering surfaces in climate technology debate

"Geoengineering was raised last week in US Congressional hearings in Washington and at a technical conference in Boston.  Academics earnestly developing solar reflection technologies warn that their progress may be overstated by US politicians and traditional energy companies seeking to avoid disturbing the US fossil fuel industry.  Harvard solar geoengineer Prof David Keith warned that “the very idea of this technology will be exploited by those who wish to block emissions cuts as a way to sow confusion.”"

Science Daily: Green roofs to reduce the effects of climate change

On Herrera-Gomez, Sergio S.; et al. (2017). "It would be necessary to have between 207 and 740 hectares of green roofs in a city like Seville (Spain), depending on the scenario that is contemplated, to reduce the effects of climate change in relation to the maximum temperature rises of between 1.5 and 6 ºC that are estimated by the end of the century. This would require between 11 and 40 percent of the buildings in the city. "
