Core Science Concepts Needed to Understand the Argument:
Difference between the natural and amplified greenhouse effect, Earth’s energy balance and radiative forcings, carbon cycle, natural causes, (Milankovitch Cycles, volcanic eruptions, solar activity, ENSO), anthropogenic/ human causes (fossil fuel combustion, changes in land-Use, cement production), climate feedbacks, global climate models) |
