International failure in curbing the global greenhouse gas emissions has sparked studies on diverse and largely hypothetical methods, known collectively as geoengineering, to intentionally mitigate climate change. At the same time, operational activities to modify weather, especially in terms of snow and rain enhancement, are taking place in more than 50 countries. Although these two topics are typically discussed separately, they are in many ways interlinked. Importantly, successful long-term weather modification and geoengineering would alter climatic conditions and the water cycle on local to regional scales.
In this session, the nexus between regional geoengineering and weather modification is discussed and analyzed. The importance of regional-scale modeling and experimental studies is specifically highlighted. All contributions are welcome, which investigate the various geoengineering and weather modification options from the local to the regional scale. Particularly encouraged are studies, which consider potential interlinkages between geoengineering and rain enhancement.
