ENV250Y5 Lecture Notes - Lecture 18: Greenland Ice Sheet, Chlorofluorocarbon, Iron Fertilization
Document Summary
If the natural greenhouse effect did not exist, the average temperature would be around -19c. Two options : reduce ghg emissions, demand-side decreasing how much we use (conservation, choose more efficient homes, cars, etc. to decrease our demand of energy, supply-side more efficient energy sources and renewable energy, choosing emission-free energy. Increase carbon sinks (geoengineering) opposite of source; absorb carbon and remove it: carbon capture and storage (ccs, a power plant emitting co2 could have different scrubbers and attachments installed to capture. Co2 that could be transported and injected into the ground into a geologically stable formation. Inject aerosols into the atmosphere to block solar radiation into the earth"s surface mimics what an erupting volcano does. Inject co2 into the sea: giant solar reflectors above the earth to reflect solar energy before it gets to the earth, governous challenges how to enforce how much geoengineering, preventing rogue actors and.
