Yale Climate Connections: What is geoengineering? … and why it’s a ‘break glass’ plan

"Everyday wisdom tells us it’s much better to avoid a problem than to try to fix it afterward. That’s one reason cutting greenhouse emissions is by far the preferred option for limiting climate change. Yet society has dragged its collective heels on climate action for decades, and it’s unclear whether the world will achieve the roughly 50% emission cuts this decade that the Intergovernmental Panel on Climate Change (IPCC) deems essential to avert the worst consequences of a human-warmed planet. Enter the notion of geoengineering. Often referred to as “climate intervention” or “climate-altering technologies,” geoengineering refers to the idea of messing with the climate system that humans have already been messing up – this time in an effort to turn back the clock and restabilize the climate."

Austin, Maura M.K.; Converse, Benjamin A. (2021): In search of weakened resolve: Does climate-engineering awareness decrease individuals’ commitment to mitigation?

Austin, Maura M.K.; Converse, Benjamin A. (2021): In search of weakened resolve: Does climate-engineering awareness decrease individuals’ commitment to mitigation? In Journal of Environmental Psychology 356 (6335), p. 101690. DOI: 10.1016/j.jenvp.2021.101690.

"As climate predictions become more dire, it is increasingly clear that society cannot rely on mitigation alone. In response, climatologists and engineers have been developing climate-engineering technology to directly intervene on the climate through strategies such as solar radiation management and carbon dioxide removal. While these technologies have some encouraging features, they also involve risk on many dimensions. One behavioral risk that concerns many observers is the possibility that the prominence of climate-engineering scenarios could decrease the public's commitment to mitigation, a concern variously described as moral hazard or weakened resolve. Across 8 experiments (N = 2514) we tested whether exposure to naturalistic information about climate-engineering technology decreases individuals' commitment to mitigation efforts."

Politico: The perils of making rules for climate manipulation

"If humanity decides to tinker with Earth's thermostat, there are going to have to be some rules on how to control the dial. Many ideas for technologies to combat global warming by intervening in planetary systems — sometimes called geoengineering — are still in the research phase. But with climate change already taking hold, some could end up getting used."

Call for Papers: Frontiers: Research Topic: Harmonizing Life Cycle Analysis (LCA) and Techno-Economic Analysis (TEA) guidelines

Deadline: 31. October 2021

"The Global CO2 Initiative convened a series of workshops and established the International CCU Assessment Harmonization Group in partnership with the following organizations. The group promotes research, development, and commercialization of carbon capture, utilization, and storage technologies requires assessing the environmental and economic opportunities and risks. Life cycle assessments and techno-economic assessments are means to quantify these opportunities and risks. For consistent conduct and transparent reporting, a common framework is needed. The mission of the International CCU Assessment Harmonization Group is to create this common framework. We are bringing together related efforts, analyze differences and seek to eliminate them where possible."
