Examine the two graphs (Figures 3 and 4) which were provided by the Department of Environmental Affairs in South Africa. The graphs show the average temperature increase during the period 1975 to 2010, and related species decline in South Africa. It can be deduced that during the period 1995 to 2005:
- an average temperature increase of 100C resulted in extinction of 2000 species.
- an average temperature increase of 50C resulted in extinction of 2000 species.
- an average temperature increase of 20C resulted in extinction of 1000 species.
- an average temperature increase of 20C resulted in extinction of 3000 species.
