"Both the Intergovernmental Panel on Climate Change (IPCC) and the International Energy Agency (IEA) point to CCS as a necessary option to reduce global greenhouse gas emissions in line with the climate goals at the lowest possible costs."

"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."

"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."

"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."
