Some of the more radical proposals to address and mitigate climate change involve geoengineering, which involves deliberately modifying Earth's climate. Evaluate how the actions listed would affect the global climate and global biogeochemical cycles by answering the questions that follow.
Option 1: Plant more trees.
Option 2: Build one or more giant reflective mirrors and send them into Earth's orbit.
Option 3: Fertilize ocean water with iron.
Option 4: Spray sulfuric acid as aerosol into the stratosphere.
-
What effect would option 3 (fertilizing ocean with iron) have on the carbon cycle? What outcome would create the carbon sink? Based on its effect on the carbon cycle, how would you expect option 3 to impact the global climate? What additional abiotic factor might limit the effectiveness of this option, and why? How would this additional factor influence your decision on when to implement this option?
