Hi everyone! 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 coming week. ---------- *MEER:RefEction zoom talk01* https://youtu.be/o8KN1TSfkAk by Bud Blumenthal 3 way conversation with Ye Tao, Bud Blumenthal and Roger Hallam about the MEER:ReflEction Framework as the optimal geo-engineering approach to planetary survival in the near term. Since CO2 reduction cannot reduce the increase of planetary heating for 200 years at minimum, extinction-level heat accumulation is predicted within the next 10 to 20 years. Immediate Implementation of Planet-level Cooling is necessary to avoid complete biological and civilisational collapse across continents, regions and societies. Various geo-engineering strategies have been proposed, tested and some are in research or deployment. However based upon first-principles approach to physical system-level thermal dynamics, it becomes abundantly clear that all are insufficient or failing in crucial aspects considering the enormous physical dimension of the problem, the energy and material resource costs or the necessity of huge time-scale of stable integrity of the system reaching 200 to years minimum and up to 1000 years. *A technofix for the climate? Marine geoengineering* https://youtu.be/_-iu7po7N6c by Heinrich-Böll-Stiftung Large-scale technological interventions to “fix” the climate crisis are moving up on the political agenda. Some climate scientists are now proposing geoengineering interventions in the oceans to halt global warming, such as fertilizing the oceans to draw down CO2 or to cover up large oceanic areas with synthetic materials to make their surfaces more reflective letting them absorb less sunlight and therefore less heat. But these schemes to manipulate our ecosystems and global natural processes come with great risks and uncertainties, as well as with foreseeable adverse impacts on marine ecosystems and human communities. *A technofix for the climate? Atmospheric geoengineering (Solar Radiation Management)* https://youtu.be/OBTVK8ajqa4 by Heinrich-Böll-Stiftung Large-scale technological interventions to “fix” the climate crisis are moving up on the political agenda. Some climate scientists are now proposing geoengineering interventions in the atmosphere to suppress global warming - most prominently SAI (Stratospheric Aerosol Injection): The idea here is to inject inorganic particles – such as sulphur dioxide – into the stratosphere to block incoming sunlight. In other schemes, plastic beads and other materials are proposed to cover ice surfaces to prevent them from melting. These schemes to manipulate our ecosystems come with great risks and uncertainties, as well as with foreseeable adverse impacts on our natural ecosystems and human communities depending on them. -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
