There are two different forms of graphs below. One has a more adequate way of presenting the information while the other seems to be very generic and hard to read. I believe graph two has a more adequate way of presenting the information and showing the affects of climate change.
Chart #1
I Believe this graph is a bad representation of climate change because of the lack of labeling. It doesn't really explain the different between the blue, green, and red lines.This graph seems to present the information in a very minimalistic way over a long period of time, making the graph more spread out and harder to read. It also doesn't represent the data far enough in depth for the last one thousand years which is where climate change has mainly came into play. Another reason this graph presents this information in a less efficient way is that it has multiple scaled which can be confusing when your trying to read.
Chart #2
This data presents the information in a much clearer format. As you can see it has easy to read X and Y axises. It also consolidated to a shorter time period which prevent the cluster and confusion thats within graph #1. It accurately represents the increase in temperature due to modern development and the industrial revolution.
