Using a time index to zoom in

When a time-series is represented with a time index, we can use this index for the x-axis when plotting. We can also select a range of dates to zoom in on a particular period within the time-series using pandas' indexing facilities. In this exercise, you will select a portion of a time-series dataset and you will plot that period.

The data to use is stored in a DataFrame called climate_change, which has a time-index with dates of measurements and two data columns: "co2" and "relative_temp".

Use plt.subplots to create a Figure with one Axes called fig and ax, respectively.
Create a variable called seventies that includes all the data between "1970-01-01" and "1979-12-31".
Add the data from seventies to the plot: use the DataFrame index for the x value and the "co2" column for the y values.
