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."

Deccan Herald: Reducing global warming: Could reflecting sunlight back into space work?

"One of the most important geoengineering options is Solar Radiation Management (SRM). SRM aims at reflecting inbound sunlight back into space, reducing the amount of heat absorbed by the earth and lowering global temperatures."

Kuswanto, Heri; et al. (2021): Impact of Solar Geoengineering on Temperatures over the Indonesian Maritime Continent

Kuswanto, Heri; Kravitz, Ben; Miftahurrohmah, Brina; Fauzi, Fatkhurokhman; Sopahaluwaken, Ardhasena; Moore, John (2021): Impact of Solar Geoengineering on Temperatures over the Indonesian Maritime Continent. In Int J Climatol. DOI: 10.1002/joc.7391.

"Climate change has been projected to increase the intensity and magnitude of extreme temperature in Indonesia. Solar radiation management (SRM) has been proposed as a strategy to temporarily combat global warming, buying time for negative emissions. Though the global impacts of SRM have been extensively studied in recent years, regional impacts, especially in the tropics, have received much less attention. This paper investigates the potential stratospheric sulfate aerosol injection (SAI) to modify mean and extreme temperature, as well as the relative humidity and wet bulb temperature (WBT) change over Indonesian Maritime Continent (IMC) based on simulations from three different earth system models. We applied a simple downscaling method and corrected the bias of model output to reproduce historical temperatures and relative humidity over IMC. We evaluated changes in Geoengineering Model Intercomparison Project (GeoMIP) experiment G4, an SAI experiment in 5 Tg of SO2 into the equatorial lower stratosphere between 2020 and 2069, concurrent with the RCP4.5 emissions scenario."

Project Syndicate: We Need to Talk About Geoengineering

"Although climate change is primarily caused by excess greenhouse-gas emissions, there are many links in the chain between economic activities and the real-world effects of planetary warming. Each of these can be addressed in different ways, and all options should at least be on the table."

Project: GeoEngineering and Negative Emissions pathways in Europe (University of Surrey)

"This project aims to investigate social legitimatization processes and deployment pathways of an effective supply chain. To do that, public attitudes, sentiments and discourses related to innovation will be analysed based a stakeholder survey instruments, focus groups, and social media data across Europe. For example, we will assess public options and perceptions (or misperceptions) of performance, risk, cost, and other factors. It will also collect information from relevant supply chain stakeholders, seeking to hurdles that need to be overcome and levers that can be exploited to successfully deploy these technologies. The results will allow us to develop strong evidence base for understanding and explaining the attitudes of different groups towards GeoEngineering and Negative Emissions innovation pathways."

Blog: Why & how we raised $1.4M to combat extreme climate change in 8 weeks and what you can do to help

"With this post I want to throw down the gauntlet to folks in games and other industries that have benefited from the pandemic to do our part to help fix the climate. Yes — I’m talking about you. The example from those who contributed to this is just a small step. There is so much more to accomplish individually and together. #doyourpart today and share it to inspire others.”
