| Figure 1.1: Variations of the Earth's surface temperature in the Northern Hemisphere for the past 1,000 years. Yearly data and running average from thermometers, tree rings, corals, ice cores, and historical records. Gray represents 95 percent confidence range.

The measurements are 'normalized' in such a way that any departure from the range from -1 to +1 degrees C might occur by change, but any departure outside of this range is probably a sign of a change in weather patterns. On this evidence, the 'normal' weather in the Sahel is drier now than in the 1950s. | |

| Figure 1.8: The rising trend of global sea level closely follows the rising temperature trend. Source: James Hansen/GISS. | Figure 1.9: This graph plots the change in position of the front of the Grindewald glacier, in Switzerland, relative to its present position since 1500. The glacier has retreated about 1.5 kilometers since 1850, and about half of this retreat has occurred since 1940. The glacial retreat mirrors the rise in global temperature. | Figure 1.10: As the Earth shifts into or out of an interglacial, temperature variations and changes in the concentration of carbon dioxide in the atmosphere move in step.
