John Martin's hypothesis led to what experimental type of geoengineering?
Carbon capture
Solar radiation management
Afforestation
Ocean iron fertilization
Answer
Ocean iron fertilization, as suggested by John Martin's hypothesis, is an experimental geoengineering technique that aims to enhance phytoplankton growth in the ocean by artificially increasing iron concentrations in iron-limited regions. By stimulating phytoplankton blooms, it intends to draw down atmospheric carbon dioxide through photosynthesis, potentially mitigating the effects of climate change.
