Solar Geo-Engineering

Santhosh Kumar 06/10/2023

Solar Geo-Engineering Mind Map
Context
Potential climate change solution
Definition
Reflect sunlight to cool Earth
SRM methods
Stratospheric aerosol injection (SAI)
Injecting reflecting particles
Marine cloud brightening (MCB)
Sea salt stimulates cloud formation
Paris Agreement target
Limit temperature increase
Below 2°C
Efforts for 1.5°C
Net global CO2 emissions zero by mid-century
Potential
Cost-effective
$18 billion per cooling degree
Carbon dioxide removal comparison
Requires more money
Implications
Polar Warming and Ice Melt
Temperature increases around poles
Impact on Monsoon Patterns
Potential rainfall and weather system disruptions
Moral hazard
Slow emission reductions risk
Delay low-carbon economy transition
Little is known about impacts
Computer-based modelling
Natural observations (e.g., volcanic eruption)
Uncoordinated Efforts
Risks of uncoordinated actions
Private companies' unregulated experiments
Example: "Make Sunsets" releases sulphur dioxide
USA’s plan
Public or private actors
Aerosols and MCB sunlight reflection
Research focus
Assess potential risks and benefits
Climate policy components
Mitigation
Adaptation
Way ahead
International governance need
Experimentation source
Only from governments
Public involvement in decision-making
Conclusion
Ethical and environmental risks
Need for public scrutiny and debate
Primary solutions
Mitigation and Adaptation
