Iron fertilization can exacerbate ocean acidity. Iron is expensive.

Chapter 16 What causes the greenhouse effect? Atmospheric gases, such as carbon dioxide, absorb sunlight, causing the atmosphere to heat up. The oceans absorb solar energy and trap heat, making the Earth warmer. Greenhouse gases lead to polar ice cap melting, making the Earth warmer. Sunlight is absorbed by the Earth’s surface, reradiated as infrared energy, and absorbed by atmospheric gases. Greenhouse gases absorb ozone, leaving the Earth unprotected from ultraviolet radiation.
