4. The rise in global temperatures has led to the melting of the sea ice in polar regions. Scientists have developed a number of computer models that can be used to make predictions about the rate of sea ice melting in these polar regions and its effect on coastal areas globally. In order to create a computer model a number of variables are identified. A computer model of the effects of the melting of the sea ice in the Arctic Ocean may include the following variables: • average ocean surface temperature (C) • albedo of the ocean (the proportion of light reflected from the ocean surface) • precipitation (mm) • salinity of the ocean (grammes of salt in one kilogramme of water) • area of sea ice (km2).
