Hello! I bring to you a small list of recent videos on the topics of Geoengineering.
There's a playlist with more videos on topic, you can check it here: https://www.youtube.com/playlist?list=PLF8369A27273314D8 Enjoy! Hope we all have a great week. *C2GLearn: How does the Working Group-II report of the IPCC 6th Assessment address CDR and SRM?* https://youtu.be/bvs4i5YrRhU?list=PLF8369A27273314D8 by C2G Carnegie Climate Governance Initiative This C2GLearn webinar aims to provide audiences with expert overviews of how the Working Group II contribution to the Sixth Assessment report addresses Carbon Dioxide Removal (CDR) and Solar Radiation Modification (SRM)? Speakers’ presentations will be pre-recorded and played to the webinar audience, with the speakers joining for the live Q&A session enabling the audience to ask clarifying questions and learn more. *D. Visioni, "Climate engineering: what do we know, what do we need to know, should we know it?"* https://youtu.be/fxqSsQ1ftQg by Labont - Center for Ontology Climate engineering (or climate intervention, or geoengineering) is a topic that is gaining prominence in mainstream climate policy discourse, especially as the chance of remaining below 1.5 ºC of warming above preindustrial levels fades. It is defined as any deliberate, large scale intervention in the climate system aimed at reducing the harmful effects of the increase in greenhouse gases. As an umbrella term, it usually includes both large scale methods of CO₂ removal from the atmosphere (Carbon Dioxide Removal, CDR) and methods aimed at reducing the incoming sunlight in order to cool the planet (Solar Radiation Modification, SRM). In this talk, I will give an overview of both CDR and SRM methods, and focus on the diverse sets of challenges they present: technological, ethical and related to governance. CDR or “negative emissions” are now present in almost all “net-zero” plans from both governments and private sector actors, and all major scenarios from the Intergovernmental Panel on Climate Change (IPCC) include some; but problems with their probable environmental impacts, land use, trade-offs with food production and technical challenges with their scalability need to be addressed, and uncertainties abound. SRM, while still at the fringe, may offer on the other hand a “cheap and easy” temporary solution capable to ameliorate some of the risks, but far more research would be necessary to understand its potential, limits, and novel risks, and some burning questions remain: whose hand would be on the thermostat, whose consent should be asked before SRM could even start, and can a global governance system capable of ensuring a “just” deployment ever be developed? *Buying Time With Geoengineering | Ye Tao* https://youtu.be/RiTDDejKqA0 by Planet: Critical Physicist and geoengineer Ye Tao introduces Meer, the mirror rays project which could halt global warming, buying humanity the necessary time to combat the climate crisis. He explains how Meer could cool the planet, decrease energy demands, improve water retention and food resources. -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
