A few days ago, I was convinced by a Nature paper that the tropical Indian Ocean has undergone changes that are consistent with what scientists expected from a warming climate. Today, I found two papers that emphasize decadal variability, at least at 32S. (Why 30S? That's a survey line that we have some data to work on.)
I need to know the answer quickly, because I have a proposal deadline. So, I emailed the first author in UK. Hope she will answer me soon...
