Annotate or explain this figure in detail. Remember to first describe the figure as if you are telling someone who has never seen it about the information it contains. Some things you will want to include or consider: What is the name of this plot? What are the axes? What are the units? What do the data represent?
Once you've described the figure, answer the following question:
1) What is the average atmospheric increase of CO2 over the duration of this plot? How does this rate compare to the rate of increase over the past ~18,000 years, prior to the industrial revolution (hint: see CO2 in the past and CO2 now slides for example calculations)?
2) Why is the rate of increase in atmospheric CO2 just as/more concerning than the absolute amount of atmospheric CO2?
