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:

400
900
1100
Graph doesn't show
850

The given graph is missing so we cannot estimate the likely total carbon dioxide release based on it.

To estimate the likely total carbon dioxide release from the given information, we need to refer to the graph. However, since the options provided do not correspond to any values on the graph, it seems that the graph doesn't show the specific carbon dioxide release data. Therefore, the answer to this question would be "Graph doesn't show".

To estimate the likely total carbon dioxide release based on the given area of Arctic sea ice, we need to refer to the graph. Unfortunately, without having access to the graph or any information about the relationship between Arctic sea ice area and carbon dioxide release, we cannot provide an accurate estimate.

However, if you have access to the graph, you can follow these steps to estimate the likely total carbon dioxide release:

1. Locate the point on the graph that corresponds to an area of 6.0 million km2 for Arctic sea ice. This could be done by finding the x-axis value (area of Arctic sea ice) that matches 6.0 million km2.

2. Once you locate the specific point on the graph, determine the corresponding y-axis value, which represents the carbon dioxide release.

3. Check which label on the y-axis matches the determined y-axis value. This will give you an estimate of the total carbon dioxide release.

Based on this, you should be able to determine the most accurate option among the given choices (400, 900, 1100, Graph doesn't show, 850).
