Daisyworld, a Computer Simulation, is a hypothetical world orbiting a star whose radiant energy is slowly increasing or decreasing.
The surprising result was that the surface temperature of Daisy World remains almost constant over a broad range of solar output.
Daisyworld was introduced by James Lovelock and Andrew Watson in a paper published in 1983 to illustrate the plausibility of the Gaia Hypothesis, which had received a highly critical scientific reception.
Plots from a basic Daisy World run with white and black daisies. Top plot shows % area covered with daisies, or barren.
Bottom plot shows the planetary temperature achieved by daisy feedback (pink) vs what the temperature would have been if the planet were barren.

In the original 1983 version, Daisyworld is seeded with two varieties of daisy as its only life forms: Black Daisies and White Daisies. White petalled daisies reflect light, while black petalled daisies absorb light.
The simulation tracks the two daisy populations and the surface temperature of Daisy World as the sun's rays grow more powerful.
