I don't think he's just talking about less evaporation meaning less ocean heat loss. (blog.hotwhopper.com)
My hunch is his question in part stems from discussions between gusbobb and Gavin concerning gusbobb's notions of ocean heat loss. (realclimate.org)
This incoming shortwave heating is balanced by ocean heat loss through back radiation (41 %), evaporative heat loss (53 %), and heat loss by conduction and convection (6 %). (realclimate.org)
