On Climate Change and (Active) Climate Management - Bert Hubert's writings
a day ago
- Climate change is real, human-caused, and the 2023 anomaly is exceptionally dangerous.
- The climate is inherently unstable, and human emissions are now a dominant force in the Earth system.
- Current efforts to reduce emissions ('abstinence only') are insufficient to meet net-zero goals by 2050.
- Solar energy is now cheaper than fossil fuels, but the transition is too slow due to political and infrastructural hurdles.
- Carbon capture and storage options exist but are controversial and face scaling challenges.
- Solar Radiation Management (geoengineering) is cheap and could rapidly cool the planet, but requires more research and governance.
- Unilateral geoengineering by a wealthy individual or nation is a significant risk.
- Despite setbacks, progress is being made toward a cleaner energy future, but urgent action and research are needed.
