  1. Humans 200 years ago began digging up and burning fossil fuels (coal, oil and natural gas). This adds carbon dioxide to the greenhouse gases in the atmosphere, which is extra to the normal carbon cycle. This is the main action causing global warming.
  2. Humans began cutting down the great forests that used to spread across the earth. Trees and vegetation remove carbon dioxide from the atmosphere and store it in their roots, trunks, branches and leaves. 50% of a tree weight is carbon. Deforestation is the second action.
