Kravitz, Ben; Sikka, Tina (2021): Conducting more inclusive solar geoengineering research: A feminist science framework

Kravitz, Ben; Sikka, Tina (2021): Conducting more inclusive solar geoengineering research: A feminist science framework. In arXiv.org Physics and Society. Available online at https://arxiv.org/abs/2109.04217.

"Solar geoengineering, or deliberate climate modification, has been receiving increased attention in recent years. Given the far-reaching consequences of any potential solar geoengineering deployments, it is prudent to identify inherent biases, blind spots, and other potential issues at all stages of the research process. Here we articulate a feminist science-based framework to concretely describe how solar geoengineering researchers can be more inclusive of different perspectives, in the process illuminating potential implicit bias and enhancing the conclusions that can be gained from their studies. Importantly, this framework is an adoptable method of practice that can be refined, with the aim of conducting better research in solar geoengineering. As an illustration, we retrospectively apply this framework to a well-read solar geoengineering study, improving transparency by revealing its implicit values, conclusions made from its evidence base, and the methodologies that study pursues. We conclude with a set of recommendations for the geoengineering research community whereby more inclusive research can become a regular part of practice. Throughout this process, we illustrate how feminist science scholars can use this approach to study climate modeling."

The Hill: A realistic response to the climate wake-up call

"Leaders across the world raised the alarm in response to the latest assessment of climate change by the Intergovernmental Panel on Climate Change (IPCC). Christiana Figueres, the former executive secretary of the UN Framework Convention on Climate Change said, 'This is a massive wake-up call that is sounding yet another alarm bell.' Al Gore warned 'There is no time left to waste,' and UN Secretary-General Antonio Guterres said, 'A code red for humanity.'"

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."

Bonou, Frederic; et al. (2021): Stratospheric Sulfate Aerosols impacts on West African monsoon precipitation using GeoMIP Models

Bonou, Frederic; Da-Allada, Casimir Yelognisse; Baloïtcha, Ezinvi; Alamou, Eric; Biao, Eliezer Iboukoun; Zandagba, Josué et al. (2021): Stratospheric Sulfate Aerosols impacts on West African monsoon precipitation using GeoMIP Models. In Earth and Space Science Open Archive. DOI: 10.1002/essoar.10507841.1.

"Stratospheric Aerosol Geoengineering (SAG) is proposed to offset global warming; the use of this approach can impact the hydrological cycle. We use simulations from Coupled Model Intercomparison Project (CMIP5) and Geoengineering Model Intercomparison Project (G3 simulation) to analyze the impacts of SAG on precipitation (P) and to determine its responsible causes in West Africa and Sahel region."

IEEE Spectrum: Here's how we could brighten clouds to cool the earth

"'Ship tracks' over the ocean reveal a new strategy to fight climate change. As we confront the enormous challenge of climate change, we should take inspiration from even the most unlikely sources. Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming.The particles produced by these ship emissions can also create brighter clouds, which in turn can produce a cooling effect via processes that occur naturally in our atmosphere. What if we could achieve this cooling effect without simultaneously releasing the greenhouse gases and toxic pollutants that ships emit? That's the question the Marine Cloud Brightening (MCB) Project intends to answer."

Ricke, Katharine; Moreno-Cruz, Juan (2020): Geo-Wedges: A Portfolio Approach to Geoengineering the Climate

Ricke, Katharine; Moreno-Cruz, Juan (2020): Geo-Wedges: A Portfolio Approach to Geoengineering the Climate. In : Reference Module in Earth Systems and Environmental Sciences, vol. 531: Elsevier, p. 362.

"A host of methods to combat climate change through geoengineering could be available soon. These methods can reduce the concentrations of carbon in the atmosphere, limit the amount of incoming solar radiation or perturb the Earth's radiation balance in other ways. They may be implemented to slow down the rate of temperature change and limit the impacts of climate change. Any one technology could be too risky or costly to do the job by itself, but a coordinated intervention that employs different methods with diverse attributes could achieve climate impact reduction goals while limiting risk."

Arab News: Use science to find solutions for cutting carbon emissions

"This week climate events have made international events every day. On Sunday, Hurricane Ida slammed New Orleans depriving over 1 million homes of power. On Tuesday, New Delhi received the heaviest rainfall in over 12 years, recording 120 mm in 24 hours, almost 90 pc of total rain that normally falls in all of September. Barely a day later, New York and New Jersey saw the highest ever rain in a single day with nearly 210 mm tumbling in under 24 hours. Indeed, for well over a year, rarely a day has gone by, when an extreme weather event – a forest fire, severe drought, a hurricane or unprecedented rain has not made it to global news. In such a situation, it is not only normal or needed, but indeed critical that governments, companies and societies put their best minds and scientists to work to find solutions that help address climate change and global warming in a meaningful manner."
