It has been suggested that global warming could be halted by fertilizing the oceans to increase the growth of algae. How might this affect the greenhouse effect?
◦ Algal photosynthesis would produce more O2, which blocks light.
◦ Algal photosynthesis would be inhibited by the addition of fertilizer.
◦ Algal photosynthesis would use up more CO2, which traps heat.
◦ Algae photosynthesis would use heat in place of photons.
