The two graphs illustrate the relationship between changes in atmospheric/global temperature with time (in years) over which various natural and anthropogenic climate factors are present. Both graphs show sharply observed but fluctuating temperature records over each five-year period between 1900 and 1920. The observed temperature anomaly is recorded as -0.3°C every five years for the entire twenty-year period. . The observed temperature variation is observed to have an increasing trend from 1920 to 1945, after which a slight decrease in temperature occurs until 1960. The recorded temperature anomaly then continues to increase until it reaches a peak of 0, 95°C. On the other hand, the line graphs of climate temperature models are smooth and depict a steady increase in the temperature anomaly from 1900 to 1960. In the first graph, which depicts natural and anthropogenic forcing, there is a sudden drop in the anomaly of the models follows a cumulative increase until the point where it reaches a peak value of 0.74°C. However, in the second graph, which involves natural climate...
