(This practical is taken from Stephen Taylor's "Greenhouse Effect" presentation.)

The Carbon Dioxide Information Analysis Center (CDIAC) has a huge database of information regarding carbon dioxide measurement.  You can find the information at:  http://cdiac.ornl.gov/trends/co2/sio-keel.html

In this task, first make a prediction.  What do you anticipate finding in the data? 

Open the webpage and make notes on:

• name of station
• geographic coordinates
• period of record
• type of environment the station is located in

Use a spreadsheet:

1. Open the digital data page
2. Select all data for a 5 year interval
3. Paste into Numbers or Excel
4. Make adjustments to spreadsheet to make sure all columns and rows are correct
5. Produce 2 line graphs (presented to meet DCP guidelines)
1. one graph should be data from one year
2. second graph should be data from a 5 year span

Look at the graphic for patterns. 

• Near your annual graph:
  
• describe the annual pattern in your data
• explain the annual pattern in your data
• Near your 5-year graph:
• describe the 5-year pattern in your data
• explain the 5-year pattern in your data
