Weband thus reduces the surface warming rate (Fig. 1b). The decadal increase of deep ocean heat uptake during the global warming hiatus period is thus thought to be the primary contributor to the slowdown of the surface warming in association with a change of phase of the AMO or IPO.

WebMantle convection is the main way heat from Earth’s interior is transported to its surface, and this heat escapes principally through mid-ocean ridges. In fact, the connected mid-ocean ridge system is in essence a 80,000 km long volcano. Escaping heat along these ridges causes hot water to circulate through the crust in a “hydrothermal system.”
