Activity #1:
I have randomlyÂ selectedÂ six measurementsÂ collected at the Mauna Loa sampling site between 1986 and 1993Â and highlighted the data in light blue. Plot the six pointsÂ on the given graph belowÂ in blue ink or blue pencil.Â To hand in eventually you will need to scan the graph or use your phone to take a photo of the graph.Â Based on your data, is CO2Â increasing or decreasing? Determine the rate of increase/decrease by calculating the slope of the lineÂ (remember back to high school science thatÂ slope=?Y/?X or change in y-variable divided by change in x-variable)Â that best passes through your six data points.
Activity #2:
The CO2Â concentration in the atmosphere is a concern because of it being an important greenhouse gas. High concentrationsÂ of carbon dioxide in the atmosphere contribute to global warming. How many years will it take for the CO2Â concentration to double its 1993 content?
Activity #3:
I have highlighted six more measurements in red this timeÂ forÂ the single year of 1988.Â Plot theseÂ sixÂ data points on your graphÂ above.Does this change your interpretation? What newÂ detail is added to theÂ relationshipÂ when the more complete data is plotted?Â WhymightÂ CO2Â vary throughout an individual year?Â Maybe think about photosynthesis by plants where CO2Â and H2O are converted into sugars and oxygen.
Activity #4:
Below is some of the most recent CO2Â data from Mauna Loa.Â AreÂ CO2Â levels higher or lower than those from the last part of the previous table?Â What is one aspect of global warming that concerns you most?
