1. what happened to the amount of carbon dioxide in the atmosphere from 2010-2017 2. how did the global temperature change from 2010-2016? 3. what is the the relationship between the amount of carbon dioxide in the atmosphere and global temperature?

1. By looking at the first graph (blue graph), we see that the amount of carbon dioxide in the atmosphere is increased from 2010 to 2017. The amount of carbon dioxide, in fact, is shown on the y-axis (while the time is on the x-axis) and we see that it has increased from 390 units in 2010 to 406 units in 2017.

2. By looking at the second graph (red graph), we see that the global temperature (shown on the y-axis) has first decreased from 0.71 to 0.6 from 2010 to 2011, then it has always increased from 0.6 in 2011 to 1 in 2016.

3. By comparing the two graphs, we can say that (at least for the period 2011-2016) there is a correlation between the amount of carbon dioxide and the global temperature: in fact, as the first one increases, the temperature increases as well, so there is a proportionality between the two quantities.

the answer is a. hope this .
