Geoengineering: A Horrible Idea We Might Have to Do
Kurzgesagt – In a Nutshell・7 minutes read
Humanity's future is at risk due to severe climate change impacts, prompting consideration of emergency geoengineering solutions like stratospheric aerosol injection to combat global warming while also posing risks such as altered weather patterns and ozone layer damage. Scientists advocate for cautious research and implementation of geoengineering interventions to mitigate climate change consequences and allow for a shift away from fossil fuels.
Insights
- Emergency geoengineering interventions, such as stratospheric aerosol injection, are being considered by world governments to combat the severe impacts of climate change, offering a potential solution to slow or halt global warming and provide a transition away from fossil fuels.
- While aerosol injections could offer benefits in mitigating climate change, there are significant risks involved, including altered rainfall patterns, ozone layer damage, and the potential for abrupt heating if the geoengineering process is suddenly stopped, highlighting the need for thorough research and careful implementation to avoid unintended consequences.

Geoengineering to Combat Climate Change: Aerosol Injection
- Humanity faces desperate times by the end of the 21st century due to heat waves, droughts, poor harvests, and diminishing fish yields, leading to famines and resource wars.
- World governments consider implementing emergency geoengineering interventions to combat rapid climate change, which could either undo centuries of human behavior or worsen the situation significantly.
- One potential geoengineering method is stratospheric aerosol injection, involving spraying sulfur particles high in the atmosphere to reflect sunlight and cool the planet by mimicking the effects of the 1991 Mount Pinatubo eruption.
- Scientists propose using a small fleet of aircraft to distribute aerosols along the Equator, projecting that injecting 5 to 8 megatons of material annually could slow or halt global warming, providing time to transition from fossil fuels.
- Despite potential benefits, aerosol injections may lead to adverse effects like altered rainfall patterns, ozone layer damage, and a termination shock scenario where abrupt heating occurs if geoengineering is abruptly halted, necessitating thorough research and caution in implementation.
