Question

Researchers are trying to use iron to stimulate phytoplankton growth. Phytoplankton removes excess carbon from the atmosphere because too much carbon makes the earth warmer. If the researchers are correct, adding iron to stimulate phytoplankton:
A: will keep Earth's temperatures constant.
B: can eventually make the Earth's temperatures warmer.
C: can eventually cool the Earth's temperature.
D: can reduce the amount of iron in the water.
E: will have no effect on its growth.

Would it be A or C?

Answer 1

Removing carbon won't necessarily make the Earth cooler but it ought to help keep the temperature constant by fighting global warming.
