Separating Human and Natural Influences on Climate

Figure 1.

This figure appears in chapter 1 of the Climate Change Impacts in the United States: The Third National Climate Assessment report.

The green band shows how global average temperature would have changed over the last century due to natural forces alone, as simulated by climate models. The blue band shows model simulations of the effects of human and natural forces (including solar and volcanic activity) combined. The black line shows the actual observed global average temperatures. Only with the inclusion of human influences can models reproduce the observed temperature changes.
