I don't see how the last sentence rules out man-made global warming as being a factor. Has the warming of the oceans accelerated? How were ocean temperature measured 100 years ago?
This is a new tact for denialists. Before some have argued that oceans are cooling.

It doesn't rule out AGW as being a factor. I didn't say that. It does show warming of the ocean as having started long before AGW would have been a concern. Which begs the question, why? Not to mention the questions you've posed above as well.
I don't see this study as "a new tact for denialists." Is it not legitimate science?
