Ocean Heat Poised To Come Back And Haunt Us? Comments about a recent post on Meehl (2011), a cli... via @skepticscience
Meehl (2011) is a climate model-based study that shows hiatus decades, of little or no increase in global surface temperatures, are relatively common even under conditions of global warming similar to the present. This see-sawing pattern of global surface temperatures has been apparent in climate model projections for some time now. These hiatus decades are simply the cool phase of a cool-warm natural cycle where heat is exchanged between the surface and subsurface ocean. The deep ocean warms during these hiatus decades because heat builds up in mid-latitude regions and is quickly funneled downwards. Heat buried in the deep ocean remains there for hundreds to thousands of years. It is not involved in the heat exchange occurring in shallower layers. Oceanic patterns in the hiatus decades are very similar to both La Niña and the Interdecadal Pacific Oscillation. So the model...
