GLOBAL CLIMATE CHANGE: THEORETICAL EXPLANATION

One approach to theoretical explanation for global climate change focuses on changes in total solar energy flux to the earth's surface. Changes in solar radiation reaching the outer surface of the atmosphere at the time scale of 10 Kyr years are driven by Milankovitch cycles in the coupled orbital and axial angular momentum systems of the earth. This effect is modulated by small amplitude perturbations in the solar energy reaching the earth's surface caused by volcanic aerosols.
