4.1.3. Non-stationarity

Try these first

1. 1.

   Define non-stationarity in your own words.

   Hint

   Think about statistical properties like mean and variance.

2. 2.

   What does a time series refer to?

   Hint

   It often relates to measurements taken at periodic intervals.

3. 3.

   What is the definition of non-stationarity?

   • A) Time consistency in data patterns
   • B) Changing statistical properties in time series data
   • C) Stability in climate measurements

   Hint

   Think about how climate data can change across years.

4. 4.

   True or False: Non-stationarity suggests that all climate variables are stable.

   • True
   • False

   Hint

   Evaluate the definition of stability in climate.

5. 5.

   You are tasked with creating a climate prediction model using data from the last century. Explain how you would account for non-stationarity in your analysis.

   Hint

   Reflect on how you can analyze previous behaviors of different variables.

6. 6.

   Discuss how the understanding of non-stationarity might affect climate change mitigation strategies.

   Hint

   Consider how reactive vs. proactive strategies differ in environmental policy.
