With reference to Fig. 7, describe the relationship between atmospheric carbon dioxide and global warming and their changes over the years.                                                                                                                                                                                                     [4]

Global warming increases with increase in carbon dioxide/Global temperature has a direct relationship with carbon dioxide. During pre-industrial level, carbon dioxide increased gradually by 260ppm with only 1 degree celsius increase in atmospheric temperature. During industrial period, carbon dioxide accounting for anthropogenic warming has increased by 280ppm. Carbon dioxide accounting for natural warming has remained constant. Carbon dioxide given out during industrialisation has resulted in increase of  temperature of 6.6 degree celsius.
