produce increasing numbers of seeds as the average surface air
temperature falls below 15°C. The black daisies produce increasing
numbers of seeds as the average surface air temperature rises above
15°C. For thousands of years the average surface air temperature of
Daisyworld II was 15°C, and the populations of the two species of
daisies were equal.
One day, a space traveler arrived to explore Daisyworld. He looked
around a bit but, being in a bit of a hurry, quickly departed. The
exhaust from his space ship was highly concentrated CO
2
. The CO
2
was transported throughout the atmosphere, and the average surface
air temperature began increasing due to the direct radiative forcing.
