Refer to the Graphs Below Representing Three Computer Simulations of Earth's

Essay

Refer to the graphs below representing three computer simulations of Earth's climate between 1850 and 2000.Blue lines represent results of the model;red lines are actual climate data.The graph A model includes only natural factors,such as solar input and volcanic activity.The graph B model includes only human-caused (anthropogenic)factors,such as fossil fuel burning and deforestation.The graph C model includes both natural and anthropogenic factors.Curves are expressed as deviations around 0,which represents the average temperature for the late 1800s.Which graph best fits the actual data? What does a comparison of the three graphs indicate about the causes of global temperature increase?
