My thinking was more to get rid of the warmth in the western Pac ex Japan. Look at the Cansips, for example. It's the only model that goes out to January, 2025 I believe. Look how the equatorial waters around and north of Australia, including the IO, have cooled vs now. Heck, even the Atlantic basin isn't that unusually warm on the whole.
I certainly can't know if the Cansips is correct, but I think it's at least a start of a way out or enough cooling to make a difference.
