Abstract. The detrimental effects of global warming on vegetation have been mathematically modelled with the application of Daisyworld. Daisyworld models explain the interaction between life and the physical environment. Daisyworld helps to describe the adaptive mechanisms for two plant
... pecies of daisy populations; namely black and white daisies. An environmental condition that affects the daisy growth rate is the Earth's surface temperature. This study aims to modify the Daisyworld equations by incorporating global warming factors into the model. The factors include ice-albedo feedback and greenhouse gases. Three different scenarios are examined, the ice-albedo feedback, greenhouse gases and a combination of ice-albedo feedback and greenhouse gases. In addition, greenhouse gases are considered with the differentiations of CO 2 . The numerical results compare the relationship between the planet temperature and fractional area of black and white daisies on the Earth's surface among the three scenarios. Under the scenario of applying both ice-albedo feedback and greenhouse gases, the results illustrate that as the Earth's average temperature increases, the plant species become more vulnerable to extinction.
