Rickels, W.; et al. (2018): Turning the Global Thermostat – Who, When, and How Much?

Rickels, W.; Quaas, M.; Ricke, K.; Quaas, J.; Moreno-Cruz, J.; Smulders, S. (2018): Turning the Global Thermostat – Who, When, and How Much? Hg. v. Kiel Earth Institut. Kiel (Kiel Working Paper, 2110). Online verfügbar unter https://www.ifw-kiel.de/de/experten/ifw-researcher-internal/wilfried-rickels/turning-the-global-thermostat-who-when-and-how-much/.

„Engineering the climate via Solar Radiation Management (SRM) is increasingly considered as a component of future climate policies. We study the strategic incentives for countries to choose the level of SRM at different times in the future, accounting for the regionally uneven effect of SRM on climate variables, heterogeneous preferences of countries for the state of the global climate, and climate change adjusted GDP growth rates.“

GlacierHub: Solar Geoengineering Could Limit Sea-Level Rise from Cryosphere

„Geoengineering, as it relates to climate change, falls into two categories. The first, atmospheric carbon removal, entails physically removing carbon dioxide from the air to reduce greenhouse gas concentrations and limit temperature rise. The second, solar geoengineering, involves injecting sulfur dioxide or another aerosol into the stratosphere to reflect a portion of incoming solar radiation, again limiting temperature rise.“

Santori, G.; et al. (2018): Adsorption artificial tree for atmospheric carbon dioxide capture, purification and compression

Santori, G.; Charalambous, C.; Ferrari, M.; Brandani, S. (2018): Adsorption artificial tree for atmospheric carbon dioxide capture, purification and compression. In: Energy. DOI: 10.1016/j.energy.2018.08.090.

„Many well-established processes can remove carbon dioxide from the atmosphere but the real technological challenge consists of concentrating and compressing carbon dioxide at the conditions for long term geological storage, with efficient use of non-fossil energy sources. A thermally-driven, negative-carbon adsorption process for capture, purification and compression of carbon dioxide from air is proposed. The process is based on a series of batch adsorption compressors of decreasing size to deliver a compressed carbon dioxide stream to a final storage.“

Science News: Faster way to make mineral to remove carbon dioxide from atmosphere

„Scientists have developed an accelerated way to produce magnesite, a mineral which can capture the greenhouse gas carbon dioxide from the atmosphere, at room temperature. Removing carbon dioxide from the atmosphere would slow global warming. This work takes a different approach to existing processes, and may make it economically viable, but it is at an early stage and is not yet an industrial process.“

Phys.org: Scientists find way to make mineral which can remove CO2 from atmosphere

„Scientists have found a rapid way of producing magnesite, a mineral which stores carbon dioxide. If this can be developed to an industrial scale, it opens the door to removing CO2 from the atmosphere for long-term storage.“

Scientists have found a rapid way of producing magnesite, a mineral which stores carbon dioxide. If this can be developed to an industrial scale, it opens the door to removing CO2 from the atmosphere for long-term storage, thus countering the global warming effect of atmospheric CO2. This work is presented at the Goldschmidt conference in Boston.

Pfrommer, T. (2018): Diverging Regional Climate Preferences and the Assessment of Solar Geoengineering

Pfrommer, T. (2018): Diverging Regional Climate Preferences and the Assessment of Solar Geoengineering. Heidelberg (Discussion Paper Series, 0654). DOI: 10.11588/heidok.00025204

„Solar Geoengineering (SG) is a set of potential technologies to counteract climate change. While SG can only imperfectly compensate for temperature changes at the regional level, studies assessing regional SG impacts indicated so far that regional temperature disparities from SG may not be as severe as previously thought. A shortcoming of that literature is its assumption that regions’ temperature preferences correspond to some historic baseline climate. I extend the main framework for examining regional SG impacts by allowing for regions to have temperature preferences diverging from the baseline climate, showing that the impact of these diverging preferences can be split into two components.“
