“The long-term objective of the Council’s important new C2G2 Initiative is to encourage policy dialogues on and to contribute to the development of governance framework(s) for climate geoengineering, which is defined as deliberate, intentional planetary-scale interventions in the Earth system to counteract climate change.”

“Christopher Preston, who has previously edited a path-breaking volume on the topic, has now produced another, specifically on justice and geoengineering.”

“This thesis suggests that ‘geoengineering’ will always be performed and expressed through unique ‘surface contents’ and contextually specific meanings. However, interpretative resources described in relation to a range of other geoengineering proposals and through more abstract entry points into thinking about geoengineering also find salience through the study frames. ‘Geoengineering’ in Haida Gwaii connects with wider cultural meanings and literatures that consider the human relationship with nature. Furthermore, the study factors are suggested to have some interpretative
overlap with ideal-typical ‘worldview’ heuristics described in earlier literatures that have sought to describe dominant currents of cultural meaning in contemporary Western society.”
“A simple process to capture carbon dioxide directly from the atmosphere has been discovered accidentally by scientists in the US. Researchers at Oak Ridge National Laboratory (ORNL) were looking at methods to remove environmental contaminations such as sulphates, chromates or phosphates from water. By chance they discovered guanidine, a simple compound, was able to absorb carbon dioxide.”
Interview with Wil Burns. “Welcome to the January edition of “Leaders in Carbon Removal”! This month we sat down to chat with Wil Burns, the Co-Executive Director of the Forum for Climate Engineering Assessment in the School of International Service at American University and a research fellow at the Center for Science, Technology, Medicine and Society at University of California, Berkeley.”
“Carbon mining is a more effective path to climate stability than emission reduction because carbon mining can remove the carbon from the air faster than we add it, providing a rapid path to prevent sea level rise, ocean acidification and loss of biodiversity.[nbsp] Importantly, carbon mining at large scale can also remove the political division caused by demands to shift away from fossil fuels, by enabling fossil fuel energy production to remain compatible with climate stability. “
“Humans have been altering Earth for millennia, but only now are we wise to what we’re doing. How will we use that wisdom?”
“Unwilling to do more to stymie global warming, governments have turned to geoengineering. This covers anything that changes weather patterns, helps to store carbon emissions, and stops the sun’s rays coming through the atmosphere. The activities range from spraying chemicals into the sky to create rain clouds to putting mirrors in the atmosphere to reflect the sun’s rays. One experiment in Canada — a rare case of these being made public — involved dropping iron filings into the ocean to kill plankton so it would sink to the bottom of the ocean and trap carbon dioxide.”

“Here review an unusual hybrid device combining photocatalysis with carbon-free electricity with no-intermittency based on the solar updraft chimney. Then we review experimental evidence regarding photocatalytic transformations of non-CO2 GHGs. We propose to combine TiO2-photocatalysis with solar chimney power plants (SCPPs) to cleanse the atmosphere of non-CO2 GHGs.”

“Power stations, ships and air traffic are among the most potent greenhouse gas emitters and are primarily responsible for global warming. Iron salt aerosols[nbsp](ISAs), composed partly of iron and chloride, exert a cooling effect on climate in several ways. This article aims firstly to examine all direct and indirect natural climate cooling mechanisms driven by ISA tropospheric aerosol particles, showing their cooperation and interaction within the different environmental compartments. Secondly, it looks at a proposal to enhance the cooling effects of ISA in order to reach the optimistic target of the Paris climate agreement to limit the global temperature increase between 1.5[nbsp]and 2 °C.“
