NASA Traces Molecular Characteristics That Heat Earth

(NASA) - Not all greenhouse gases are created equal. Some trace gases are much more efficient global warming agents than the abundant carbon dioxide, which is why scientists are studying the physical characteristics that cause heat absorption to vary among different types of molecules.

Carbon dioxide receives a lot of attention because it is abundant and its concentration is increasing in the atmosphere. Methane is a trace gas that absorbs heat about 200 times more efficiently than carbon di [...]
