"In the face of rising global temperatures, deploying technologies to change Earth's climate has gone from thought experiment to reality. We already capture carbon and store it underground. Now some researchers are suggesting we should spray the clouds with particles to reflect sunlight, fertilize the oceans to promote carbon-absorbing plankton growth, or build a gigantic shade that orbits Earth and opens as needed to shield the planet from the sun. Welcome to the Anthropocene — the era of humans engineering the world in unprecedented ways."

" In light of concerns over risks, a newer set of scenarios is desirable, which represents both uncertainties and social choices more fully. Borrowing and extending lessons from recent literature on the new community climate scenario process, we envision a possible scenario-building process that combines interdisciplinary scholarship with the involvement of stakeholders and citizens. The resultant scenarios would better characterize uncertainties of, and policy choices for, solar geoengineering, and foster critical appraisal of its risks and benefits."

"Research into 'solar geo-engineering' plan is now dominated by rich nations. The technique would mimic volcanic eruptions to cool Earth by dimming the sun. But, scholars from developing countries argue that the poor are most vulnerable. They argue developing countries 'must lead on solar geo-engineering research'"

"Scientists in developing nations plan to step up research into dimming sunshine to curb climate change, hoping to judge if a man-made chemical sunshade would be less risky than a harmful rise in global temperatures." (see update)
