Suggested learning objectives: To understand that human activities produce greenhouse gases. To analyse the growth of greenhouse gases and what contributes to it. Be able to explain the enhanced greenhouse effect (as well as the natural greenhouse effect). (carbon dioxide, methane) that cause the enhanced greenhouse effect.
