We discussed multiple greenhouse gasses and how they affect climate change different.  Substances such as CO2, Methane, Water, CFCs all have different global warming potentials and different persistence in the atmosphere. We know that CO2 has lower global warming potential than water does, however we focus on curbing CO2 emissions.  Explain why we focus our efforts on reducing CO2 emissions in order to fight climate change?
