- 1. Multiple Choice
Shows global mean surface temperature anomalies. The top graph shows how the average results of climate models are consistent with observed data if the models include both anthropogenic (greenhouse gas emissions) and natural forcings (i.e., volcanic eruptions, variations in solar radiation, etc.). The bottom graph shows how removal of anthropogenic forcings creates an anomaly in the modeled and observed historic data.
What question is the caption trying to explain?
It explains how we know humans have contributed to the greenhouse gas emissions and the carbon dioxide levels detected in the past were not solely caused by natural occurrences.
It explains how the recorded temperature levels are the result of the natural forces of the universe and Earth's formation.

a temporary drought

Global sea level has risen by about 8 inches since reliable record keeping began in 1880. It is projected to rise another 1 to 8 feet by 2100. This is the result of added water from melting land ice and the expansion of seawater as it warms.

melting glaciers and record snowstorms
record rainfall and water formation
warming ocean water and melting glaciers
