The uploaded image shows a statistics problem involving climate change, focusing on the relationship between atmospheric CO₂ concentration and temperature anomaly. You are tasked to find the correlation coefficient (r) between these variables based on the regression analysis or scatterplot provided via links in the homework question.

To help you find the solution, you should:

1. Check the scatterplot, regression output, or residual plot linked in the problem for the correlation coefficient \( r \).
2. If you can't directly access the links yourself (as I can't do so in this case), you need to locate the correlation coefficient value in the regression output provided. It might also be labeled as \( r \) or \( r^2 \) (coefficient of determination).

If \( r^2 \) is provided, you can compute \( r \) as follows:
\[
r = \pm \sqrt{r^2}
\]
The sign of \( r \) is determined by the slope of the regression line (positive slope means positive \( r \), and negative slope means negative \( r \)).

Let me know if you'd like detailed help on interpreting regression outputs, scatterplots, or further assistance with the correlation computation.

### Follow-Up Questions:
1. Do you have access to the regression output, and can you share the value of \( r^2 \) or the slope of the regression line?
2. Is there any specific detail from the scatterplot that helps determine the direction (positive or negative) of the relationship?
3. Are there additional data points or tables to analyze?
4. What statistical software or method are you using to calculate these metrics?
5. Would you like a step-by-step explanation of how correlation and regression work?

### Tip:
The correlation coefficient \( r \) always lies between -1 and 1, where the sign indicates the direction of the relationship, and the magnitude indicates the strength of the relationship.

What is the correlation between CO₂ and Temperature Anomaly? The problem involves analyzing regression outputs, scatterplots, and residual plots to find the correlation coefficient (r) between these variables. It pertains to the impact of CO₂ levels on climate change.
