„Despite the cleverness of geoengineering, one frequently encountered counterargument is that geoengineering alone is not a sustainable solution in the long term, as it does nothing to reduce the amount of greenhouse gases pumped into the atmosphere and can often have negative side effects on the environment.“

„Artificial fertilisation of the ocean has been proposed as a possible geoengineering method for removing carbon dioxide from the atmosphere. The associated increase in marine primary productivity may lead to an increase in emissions of dimethyl sulphide (DMS), the primary source of sulphate aerosol over remote ocean regions, potentially causing direct and cloud-related indirect aerosol effects on climate.“
„So from the cruel fantasy of Plan C we are obliged to return to Plan A, and do all we can to slow the geological clock that has ticked over into the Anthropocene. If, on this Earthen beast provoked, a return to the halcyon days of an undisturbed climate is no longer possible, at least we can resolve to calm the agitations of “the wakened giant” and so make this new and unwanted epoch one in which humans can survive.“
„Finding a technology to shift carbon dioxide (CO2 ), the most abundant anthropogenic greenhouse gas, from a climate change problem to a valuable commodity has long been a dream of many scientists and government officials. Now, a team of chemists says they have developed a technology to economically convert atmospheric CO2 directly into highly valued carbon nanofibers for industrial and consumer products.“
Media response to Applegate, Patrick J.; Keller, Klaus (2015). „Albedo modification, an emerging technology with the potential to offset some aspects of climate change, shouldn’t be counted on as a short-term solution to stop rising global sea levels, according to a new study from Penn State geoscientists.“

„Here, we assess AM’s ability to reduce GIS sea-level contributions over decades to centuries, using a simplified ice sheet model. We drive this model using a business-as-usual base temperature forcing scenario, as well as scenarios that reflect AM-induced temperature stabilization or temperature drawdown.“

„However, some side effects of large-scale biochar application need to be investigated. In particular a massive use of a low-reflecting material on large cropland areas may impact the climate via changes in surface albedo. Twelve years of MODIS-derived albedo data were analysed for three pairs of selected agricultural sites in central Italy.“
CfP for the International Sociological Association Conference. „This session addresses many of the questions that are left out of the discussion, such as: What is the relationship between capitalism and climate geoengineering? Is geoengineering a necessary consequence of capitalism or can it be avoided in an ecologically modernized regime of ‘green’ capitalism?“

„Here, using state-of-the-art carbon–climate models, we quantify the trade-off between these two options in RCP2.6: an Intergovernmental Panel on Climate Change scenario likely to limit global warming below 2 °C. In our best-case illustrative assumption of conventional mitigation, negative emissions of 0.5–3 Gt C (gigatonnes of carbon) per year and storage capacity of 50–250 Gt C are required. In our worst case, those requirements are 7–11 Gt C per year and 1,000–1,600 Gt C, respectively.“
