Rather, excess CO2 returns toward baseline at a multitude a different rates, with chemical equilibration in the ocean occurring over decades (depending on depth), ocean carbonate buffering through sediment dissolution requiring centuries to millennia, and eventual restoration of carbonate sediment levels by terrestrial weathering occurring over hundreds of thousands of years — a long «tail» that can account for as much as 20 to 40 percent of CO2 excess in the estimates described by David Archer et al in CO2 Atmospheric Lifetimes.

One can logically wonder at just how much Dr. Dorney knows if he begins his testimony with «Today the surface ocean is almost 30 % more acidic than it was in pre-industrial times, and over the next few decades, the level of acidity of the surface ocean will continue to rise...» when the worries about acidic oceans is pointless since where is the base line?

Since Trenbreth did not provide a mechanism for the heat to go from the atmosphere to the lower levels of the ocean, and since we are talking about the same amount of heat, that which would make the atmosphere not climb in temperature for 10 to 15 years, it is much much more reasonable to assume the heat went from the surface of the ocean to Trenbreth's depths (the ocean simply overturned).
What is happening here is that the two (Hansen and Trenberth) whom you describe as «not, in fact, fanatics blinded by dogma» were surprised by the recent «lack of warming» (i.e. slight cooling) of the atmosphere as well as the upper ocean, despite CO2 increase to record levels, as this does not provide much support for the premise that human CO2 is driving our climate.
This means, that «fresh» water is coming up from the lower layers constantly, and before the whole ocean is adjusted to new CO2 levels, it takes much longer time.
The first is climate inertia — on very many levels, from fossil lock - in emissions (decades), ocean - atmospheric temperature inertia (yet more decades), Earth system temperature inertia (centuries to millennia) to ecological climate impact inertia (impacts becoming worse over time under a constant stress)-- all this to illustrate anthropogenic climate change, although already manifesting itself, is still very much an escalating problem for the future.
