The process of climate change can be influenced by atmospheric composition change from natural sources such as volcanoes A or human-mediated sources such as electricity power stations B Clearly the two mechanisms of gas release have many significant differences, including the origins of the gases, nuanced sciences, rates, and policy implications, but their influence on the process of climate change is governed by identical laws of chemistry and thermodynamics. When considered holistically in the context of climate change, the two mechanisms are not THAT different, and are not two separate processes.
