Climate Engineering - TechEthos

Climate EngineeringTechEthos defines climate engineering as a technology family which enables the modification of natural processes [...] More represents a family of technologies – including primarily techniquesA technique is a procedure for realizing a goal [...] More for Carbon Dioxide Removal and for Solar Radiation Management – that could mitigate human-induced climate change. We distinguish between two main forms of Climate Engineering: Carbon Dioxide Removal (CDR), which removes atmospheric CO2 and store it in geological, terrestrial, or oceanic reservoirs, and Solar Radiation Management (SRM), which aims to reflect some sunlight and heat back into space. Seven out of 15 science cafés were dedicated to the Climate Engineering technology family and addressed topics ranging from climate change and energy sources to technologies like carbon capture and storage (CSS), bio energy carbon capture and storage (bio-CCS) and solar radiation management (SRM). We address them to EU policymakers and officials involved in the preparation of legislative or policy initiatives related to climate action, climate technologies, climate engineering, geoengineering, carbon removal, and CDR specifically.

This method of geoengineering has benefits and drawbacks – on the one hand, it is easily and quickly implemented and potentially very effective, but on the other hand, it has the potential risk of affecting weather patterns and as a result evoke droughts, flooding, and catastrophic crop failures (How artificially brightened clouds could stop climate change, 2019). Additionally, stratospheric aerosol injection “differs from GHG mitigation (emission reduction and CO2 removal) in two key ways: (i) its direct deployment costs are potentially lower; (ii) its effects are potentially rapid and large, and as all other geoengineering technologies, it does not treat the root cause of climate change: the concentration of greenhouse gasses in the atmosphere ” (Honegger, Michaelowa and Ran, 2021). However, while geoengineering has the potential to stop the immediate most severe impacts of climate change, there are also substantial risks associated with this technology, such as increased acidification, effects on regional climates, depletion of the ozone layer, and more acid depletion.

Comparing the benefits and risks of solar geoengineering

https://climate.uchicago.edu/insights/comparing-the-benefits-and-risks-of-sol…

Our paper, *Impact of solar geoengineering on temperature-attributable mortality*, is a first effort to provide a quantitative risk-risk comparison for any solar geoengineering method. David was part of prior collaboration with Gabe Vecchi which produced an important estimate of solar geoengineering’s potential to reduce regional climate hazards. * Many groups have called for risk-risk analysis of solar geoengineering including the National Academy, NASEM 2021, The Carnegie Climate Governance Initiative, C2G and the call-for-balanceletter with Peter Singer, James Hansen, and Bjorn Stevens, as signatories, see paper. * The air pollution mortality estimate by Eastham combines the direct impacts of injected aerosol that makes it to the surface with climate-mediate changes in the amount of surface ozone and particulate air pollution produced from given industrial emissions. While not comprehensive, these are important risk pathways: temperature-attributable mortality may account for more than half of the monetized harms of climate change, and air pollution and ozone loss are among the most salient impacts of stratospheric sulfate geoengineering.
