QUESTIONS:
Scientific graphs often display information about multiple different data sources. For example, examine the more complex graph in Figure 2 and answer the questions below: Current 400 Because environmental science data is geographic in nature, data is commonly represented in choropleth maps. The anomaly map in Figure 3 was shown in this week's lecture slides. You can refer to the Tutorial 1 Appendix for information on how to interpret choropleth and anomaly graphs. Examine the map and answer the questions below. 350 co, concentration, ppm -3008 250 200 Antarctic temperature, 150 mwillen wat Copernicus CECMWF Figure 3.

On this map, what does a surface air temperature anomaly of O°C mean? (1) Figure 2.
