New computer simulations show the extent that average air temperatures at Earth's surface could warm by 2080-2099 compared to 1980-1999, if (top) greenhouse gases emissions continue to climb at current rates, or if (bottom) society cuts emissions by 70 percent. In the latter case, temperatures rise by less than 2 C (3.6 F) across nearly all of Earth's populated areas. However, unchecked emissions could lead to warming of 3 C (5.4 F) or more across parts of Europe, Asia, North America and Australia.
