Graph 1 shows an upward trend in global temperatures over time. Graphs 1 and 2 together indicate that global temperatures have risen as carbon dioxide levels have increased, supporting the conclusion that human activity like burning fossil fuels has contributed to global warming. However, Graph 3 does not evaluate the accuracy of this conclusion. Graph 4 supports the conclusion that human activity has caused global warming by showing rising carbon dioxide levels corresponding to industrialization. A limitation of Graph 4 could be that it only shows data from the past 800,000 years.
