List and discuss pre industrial movement of carbon exchange as a steady process state.
List and discuss post industrial revolution exchange of carbon dioxide brought about by human activities.
Discuss the combustion of fossil fuels and increases in heat retention within the biosphere.
Discuss tree harvesting, cutting and burning allowing more carbon into the atmosphere,
From a diagram of the carbon cycle, discuss how some of this increase is offset by absorption of carbon into the oceans.
