Global Citizen: To Slow Climate Change, Why Don't We Just Block the Sun?

"Imagine a capsule is launched 70,000 feet into the sky above Arizona and begins to release 100 grams of sulfur, calcium carbonate, or some other substance into the atmosphere. The device then floats back and forth through the ensuing cloud for the next several hours before it disperses, measuring chemical reactions and seeing how much sunlight is being blocked."

FCEA Blog: Whose Voice Matters in Climate Geoengineering?

"When I got seriously interested in climate engineering, about 2011, there was little consideration of the diversity of effects it might have on different groups and their interests. Today it has become almost commonplace to acknowledge the importance of hearing voices from a range of countries, thanks in no small measure to the pioneering efforts of the SRMGI. The importance of hearing from publics rather than merely experts is also increasingly embedded in the discourse, although rich deliberation – revealing not only how thoughtful publics can be, but how the different circumstances of deliberation can shape outcomes – has been largely limited to one or two countries in the WEIRD world (White, Educated, Industrial, Rich, Democratic)."

Call for Papers: Towards a 1.5°C World: The Ocean Response

Deadline: 06. September 2017

"This session welcomes abstracts exploring the response of the ocean under scenarios aiming towards a 1.5oC world and how it may feed back to the other components of the Earth system. Relevant issues may include hysteresis effects in ocean circulation or sea-ice, the response of the ocean carbon and other biogeochemical cycles, ecological impacts, and potential unanticipated impacts of geoengineering measures."

The Union Edge: If we learn to control the weather, can we stop climate change?

Radio broadcast (min 20:00). "Geo engineering is the deliberate large-scale manipulation of an environmental process that affects the earth’s climate, in an attempt to counteract the effects of global warming. Is this a good idea? Dr. Patricia DeMarco invites Wil Burns to discuss the potential benefits and risks, as well as the moral, ethical and political considerations of this budding technology."

University of Melbourne: The Great Barrier Reef is dying. Is it time to engineer the climate?

"In the absence of a sudden and rapid reduction in global greenhouse gas emissions, recovery options are few and tenuous.  In fact, that’s a generous assessment.  We have basically reached the point where anything that provides a glimmer of hope is “worth a crack”. One such proposal is to cool the ocean around the reef by “brightening” clouds overhead.  Modelling and measurements indicate that increasing cloud cover and density would reduce water temperatures around the reef, although whether the effect is sufficient to arrest coral bleaching is uncertain."

Duurzaam: Climate change can not be faced without geo-engineering (Dutch)

"It will be another job to limit global warming to 2 degrees Celsius.New scientific research states that large-scale filtering of CO2 from the sky is inevitable." (Dutch, auto-translation)

FCEA Blog: Increasing Ambition with Blue Carbon: Protecting Coastal Wetland Ecosystems as a Carbon Dioxide Removal Strategy to Meet the Paris Agreement’s Goals

"The basic idea is to protect coastal wetland ecosystems – mangroves, seagrass beds and salt marshes – because the plant biomass and soils sequester and store carbon at rates up to 50 times higher than their terrestrial counterparts. While sequestration and storage can vary greatly across geographies and ecological conditions, it is estimated that global blue carbon systems store at least 45 Mt CO2 per year. It is further estimated that if coastal wetlands were restored to their extent in 1990, annual carbon sequestration would increase to 160Mt CO2 yr-1. Blue carbon ecosystems also provide a suite of co-benefits, including mitigating sea level rise, providing critical fisheries habitat, and nutrient filtration."
