Create Stage Objective: Provide answers for the questions in the “Create Stage” instructions.
Regarding paleoclimatological data that includes measurements of [CO2] for at least the past 100,000 years.
- Obtain and identify the source of this data. Share a view of the data in your submission.
- Briefly, how are [CO2] measurements extracted from the data?
- From the data, estimate the minimum, maximum, and average values [CO2] over a time interval of your choosing that is covered by the data.
- Based upon the average value, estimate the [CO2] in 2022 (present) and 2100 (future)

- RegardingMauna Loa Observatory data for the [CO2] at present and in ‘recent’ past.
- State the current value for [CO2]. Convert this value to a percentage.
- Qualify the proportion of Earth’s atmosphere that is [CO2] in relative terms. (Feel free to introduce an analogy, for example – other than one based on counting Smarties!)
- What does your intuition suggest about this proportion in the context of climate change? Why?
- Using one of the Keeling Curves:
- Estimate the current value for the [CO2].
- Choose a time in the past that is covered by the curve and estimate [CO2].
- Using your past and present estimates for the [CO2], estimate the growth rate for this gas in our atmosphere.
- Based on this growth rate, estimate [CO2] in 2100.
