There is a bar chart below the graph you just completed, and the horizontal time axis in the bar chart is identical to the horizontal axis in the Nisqually Glacier graph. Notice the blue and salmon pink graph of climatic data at the bottom of your graph (part B) provided by the NOAA National Climatic Data Center (NCDC). NCDC's global mean temperatures are mean temperatures for Earth calculated by processing data from thousands of observation sites throughout the world (from 1880 to 2018). The temperature data were corrected for factors such as increases in temperature around urban centers and decreases in temperature with elevation. Although NCDC collects and processes data on land and sea, this graph shows the variation in annually averaged global land surface temperature only since 1880. 1.
