Yes - to be clear, the author knows this is the confounder. That's why it was silly of the author to claim that the paper would describe a correlation without a trivial confounder.
Land area isn't well-correlated with the other three columns in the table.
Yes it is! I calculated R = 0.58, 0.81, 0.92, respectively. These will be highly significant, comparable to the p-value in the headline.
