In their simulations of how the sea's ponderous flows of water and heat affect climate, including future greenhouse warming, climate modelers assumed that something evenly stirred the world ocean from top to bottom around the globe. But oceanographers gauging the tides of the world's seas from a satellite perch have found intense patches of tidally driven mixing deep within the open ocean. Once modelers include these patches, they should see some changes in model predictions of global warming.
