Daisyworld Model

James Lovelock, Andrew Watson, Dave Bice, Dept. of Geosciences, Penn State University

The simulation exercise uses a STELLA-based model called Daisyworld to explore concepts associated with Earth's energy balance and climate change. Students examine the evolution of a simplified model of an imaginary planet with only two species of life on its surface -- white and black daisies -- with different albedos. The daisies can alter the temperature of the surface where they are growing.
