It is difficult to determine the effect of CO₂ on climate because the atmospheric concentration of methane,another "greenhouse gas" is so much greater.

Question

Quizplus · Accepted Answer

COS (Carbonyl Sulfide) and methane are both greenhouse gases, but their atmospheric concentrations and impacts on climate are considered independently. Methane is indeed a potent greenhouse gas with a much higher concentration than COS, but the difficulty in determining COS's effect on climate is not due to methane's greater concentration. Instead, it's related to the complexity of COS's sources, sinks, and its lesser overall impact on climate compared to more abundant greenhouse gases like carbon dioxide and methane.
