How do computer models contribute to separating natural from human-caused global warming?
What will be an ideal response?
Computer models can be used to calculate global temperatures based on changes in Earth's energy budget that can be related to both natural processes and human activities. The temperatures calculated from the computer models can then be compared to the actual measured temperatures. If only natural processes are used in the computer models, then the calculated and measured temperatures are similar prior to about 1970. After 1970, however, calculated and measured temperatures match only by including warming attributed to human activities.
