JOB OPPORTUNITY Postdoc I at University Corporation for Atmospheric Research (UCAR) | United States, Colorado, Boulder | Deadline: 14 August 2023 “Here is a brief summary of what one would expect to be generally responsible for in this role: -The employee will work with the team on the Earth Radiation Budget (ERB) Initiative Project at NCAR. The work includes performing and analyzing model experiments with two aerosol models within the Community Earth System Model (CESM) Version 2, the CARMA sectional aerosol model, and the existing modal aerosol model. The work further includes contributions to the continued development and evaluation of the aerosol model with observations. The employee set up, and perform stratospheric aerosol injection (SAI) experiments and develop possible adjustments and sensitivity simulations for the CARMA model. The employee will further perform future simulations with stratospheric aerosol injections. The employee will also conduct independent research and write papers on the results. -The employee will set up and perform stratospheric aerosol injection simulations in CESM2/WACCM with the sectional aerosol model CARMA using different injection materials (e.g., sulfur vs sulfuric acid). The employee will participate in model development that requires changing and improving the CARMA and atmospheric model code and will evaluate it to improveperformance compared to observations. The employee will participate in weekly team meetings. -The employee will perform independent research on developed and performed experiments, write scientific papers, and present them at meetings focusing on comparisons between sectional and modal aerosol model descriptions for experiments in past, present, and future conditions with and without stratospheric aerosol injections. The employee will contribute to writing computer time proposals required from model simulations. -Identify the best setup for model simulations to be best suited for the science question and consider computational efficiency before performing simulations. -Identify model improvement needs, and experimental design to apply SAI. -Identify reasons for differences between using different aerosol schemes for SAI.” PODCASTS Efrat Fenigson: Catastrophic Risks of Solar Geoengineering “Global research into solar geoengineering, or solar radiation modification (SRM), is gaining momentum. Late in June, the White House released a report calling for more exploration of such technologies, while the European Union called for a collaborative risk assessment of the SRM. In this interview with The New American, investigative journalist Efrat Fenigson discusses the U.N. report “One Atmosphere: An Independent Expert Review on Research and Deployment of Solar Radiation Modification,” published in February 2023. The report examines such methods of the SRM as stratospheric aerosol injections (SAI), whitening of the marine clouds, covering deserts with reflective materials, cultivating GMO plants that would reflect sun rays, and deploying mirrors in space. SAI, the most researched of the methods, is already being tested globally, despite the severity of the risks it poses to human health and broader ecosystems. That includes altering precipitation patterns, reducing crop yields, causing acid rains that would contaminate water and soil, and depleting the ozone layer. All of the consequences would be utilized to establish more control over the desperate populace while also filling the coffers of the corporate members of the World Economic Forum (WEF) as well as figures such as Bill Gates. The journalist warned against accepting the fraudulent narrative of climate change, asserting that its aim is to exert control over people by employing mechanisms like Central Bank Digital Currencies (CBDC) linked to resource rationing.” How will the Alliance for Just Deliberation on Solar Geoengineering support just and inclusive discussions? | C2GTalk “Consultation and engagement with civil society in the Global South is essential for inclusive governance of solar radiation modification (SRM), says Dr Shuchi Talati, the founder of the Alliance for Just Deliberation on Solar Geoengineering. This will not be easy, and requires building trust and knowledge over time, but as international attention to SRM increases, it will be increasingly important to empower vulnerable communities.” Aerosol plume modelling - Sun | Reviewer 2 does geoengineering Aerosol plume modelling - Sun Reviewer 2 does geoengineering 1:22:04 “How do you model aerosol dispersal from an aircraft? Then, how do you integrate that into a climate model?

(Slight cooling, but it's complicated) What do background variations in dust levels teach us about the likely effects of SRM & CDR? (Lots) Should we try to reduce anthropogenic mineral dust? (Probably not) How does reindeer poo fit into all of this? (You'll have to listen) Jasper Kok speaks to @geoengineering1 about his paper "Mineral dust aerosol impacts on global climate and climate change.” YOUTUBE VIDEOS Geoengineering: Is the earth ready for some sunblock? | WION Climate Tracker | WION “Big ideas emerge for slowing climate change.
