Guiding Questions
- Atmospheric CO2 wiggles every year while rising. Separate the data into a trend and a seasonal cycle.
- Fit a sinusoidal model to the seasonal part. Why does CO2 dip in the northern summer?
- Is the underlying trend linear, quadratic or exponential? Compare fits and justify your choice.
- Use your combined model to predict next year's curve, then check it against the live data.
