al. correctly predict that the land surface will warm more than the ocean surface, and that the southern ocean warming would be temporarily suppressed due to
the slower ocean heat uptake.
You however are assuming (it seems to me) that because when you plot net flux against T, you don't get a straight line, that the explanation must be something to do with how fast or
slow the ocean heat uptake is.

If the greenhouse effect (that checks the exit of longwave radiation from Earth into space) or the amount of absorbed sunlight diminished, one would see a
slowing in the
heat uptake of the
oceans.
For example: 1) plants giving off net CO2 in hot conditions (r / t aborbing)-- see: http://www.climateark.org/articles/reader.asp?linkid=46488 2) plants dying out due to
heat & drought & wild fires enhanced by GW (reducing or cutting short their
uptake of CO2 & releasing CO2 in the process) 3)
ocean methane clathrates melting, giving off methane 4) permafrost melting & giving off methane & CO2 5) ice & snow melting, uncovering dark surfaces that absorb more
heat 6) the warming
slowing the thermohaline
ocean conveyor & its up - churning of nutrients — reducing marine plant life & that carbon sink.
I haven't looked at the research paper in detail, but the general
slowing of sea level rise after 2004 - 2005 fits in with the sharp acceleration of
heat uptake into the
ocean during 2000 - 2005, and a
slower rate of
heat uptake thereafter.
The recent trend in sea level rise is consistent with
ocean heat uptake, so we shouldn't be surprised that the recent trend in sea level rise has
slowed somewhat too.
Vast and
slow to change temperature, the
oceans have a huge capacity to sequester
heat, especially the deep
ocean, which is playing an increasingly large
uptake and storage role.
«But the other thing I want to point out,» England added, «is that greenhouse gases in the atmosphere are at such high concentrations compared to what they were 100 years ago that you don't need to bring
heat back up from the
ocean to the surface to get future warming — you just need to
slow down the
heat uptake by the
ocean, and greenhouse gases will do the rest.»
The
slowed surface warming is due in large part to changes in
ocean cycles, particularly in the Pacific Ocean, causing more efficient ocean heat uptake, thus leaving less heat to warm surface temperat

Considering all the short - term factors identified by the scientific community that acted to
slow the rate of global warming over the past two decades (volcanoes,
ocean heat uptake, solar decreases, predominance of La Niñas, etc.) it is likely the temperature increase would have accelerated in comparison to the late 20th Century increases.
The discrepancy is likely accounted for by excessive
ocean heat uptake at low latitudes in our model, a problem related to the model's
slow surface response time (Fig. 4) that may be caused by excessive small - scale
ocean mixing.
«In our mor recent global model simulations the
ocean heat -
uptake is
slower than previously estimated, the
ocean uptake of carbon is weaker, feedbacks from the land system as temperature rises are stronger, cumulative emissions of greenhouse gases over the century are higher, and offsetting cooling from aerosol emissions is lower.
When the turnover
slows down, the usual
heat uptake by the
ocean resumes, which is only a bit less.
Specifically, he pinpoints the
slow response to
ocean heat uptake in the high latitude regions, where the
oceans are most unstable to vertical mixing.
And again, and again, and again, if the
oceans are
slow on the
uptake of
heat energy, where is the
heat energy hiding in the meantime / maritime?
BBD, And the rate of
ocean heat uptake modulates the rate of surface warming (recently, it is
slowing it).
And the rate of
ocean heat uptake modulates the rate of surface warming (recently, it is
slowing it).
The
slowed surface warming over the past decade seems to be a result of more
heat accumulation in the
oceans due to short - term increase in
ocean heat uptake efficiency.
When applying this statistical correction, Watanabe et al. found an enhanced overall
ocean heat uptake, which suggests that the
slowed surface warming can be explained by internal variability transferring more
heat to the deep
oceans, consistent with previous research.
