To estimate the likely total carbon dioxide release, we can use the information provided in the graph. From the graph, we can see that the average carbon dioxide release per unit area of Arctic sea ice is approximately 45 million metric tons per million km^2.
Therefore, to estimate the total carbon dioxide release, we can calculate:
Total carbon dioxide release = Average carbon dioxide release per unit area * Area of Arctic sea ice
Total carbon dioxide release = 45 million metric tons per million km^2 * 6.0 million km^2
Total carbon dioxide release = 270 million metric tons
So, using the given information, the likely total carbon dioxide release would be approximately 270 million metric tons.
For an example of the second view, assume that you know that the area of Arctic sea ice is 6.0 million km2
. Using the graph, estimate the likely total carbon dioxide release:
