Describe the principal differences between the kingdom Animalia and the kingdom Plantae.
Temperature measurements at the surface of land and oceans can be collected from places all over the world. A mean global surface temperature for land and ocean together can then be worked out for a chosen time interval. Scientists found the mean global temperature for the twentieth century and the mean global temperature for each decade from 1880 to 2020. Each decade's mean temperature was then compared with the twentieth-century mean. For every decade, the temperature difference was calculated. These calculated differences are shown in Fig. 10.2.
