Given that the other important variables (sea surface temps, depth of the warm layer, and atmospheric moisture) are all predicted to increase, it seems hard to make the claim that tropical cyclones will be unchanged, just as it seemed unwise to claim that Lyman et al's «

oceans» meant that climate models had fatal flaws.
The set of Comments and the original posting on Real Climate have advanced the discussion of the signficance and the issues associated with the observed
recent upper
ocean cooling.
... The
recent cooling of the upper
ocean implies a decrease in the thermosteric component of sea level.
----- On a matter unrelated to the late Sir Arthur: @Thapa (# 5), see NASA's current issue of The Earth Observer (page 16): «These findings were enough to convince the scientists who initially reported the
ocean cooling [Willis et al. (2007)-RSB- to go back and closely reexamine the
recent ocean heat storage data they had collected.
Solar forcing has increased over the 20th century and given that the
oceans have not yet had time to equilibrate to the new levels of forcing, it must have contributed some to the
recent warming, in fact, that equlibration was further delayed by the
cooling period, so the unrealized climate commitment would have been greater than ordinarily expected given that most of the increase in solar activity occurred in the first half of the century.
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.

Which conveniently ignores Science News» Oct. 5th article: Global warming hiatus tied to
cooler temps in Pacific, which states «The
recent pause in global warming has resulted from
cooling in the tropical Pacific
Ocean, new simulations find.
Also, wouldn't there need to be data showing much more
ocean cooling if the AMO PDO were a significant factor in
recent warming?
Scientists studying
oceans demonstrate that the
recent warming, to the end of the last century, is part of the natural cycle of oceanic oscillations and predict a thirty year
cooling phase.
With the
recent decline in solar flux and the shift to
cool phases of
ocean oscillations, natural climate change suggests that although glacier retreat and sea level rise will likely continue over the next few decades, the rates of sea level rise and glacier retreats will slow down.The next decade will provide the natural experiment to test the validity of competing hypotheses.
This snowpack accumulation near the poles, which gets its water via the Arctic and Antarctic
oceans, that in turn rob it from equatorial latitudes of our
oceans, also results in a reduction in the earth's spin axis moment of inertia and causes the spin rate to increase as evidenced in the
recent history of the rate at which Leap Seconds are added to our calendar (see Wysmuller's Toucan Equation for more on this evidence that during this warm time with much greater polar humidity, earlier seasonal, later seasonal and heavier snows are beginning to move water vapor from the
oceans to the poles to re-build the polar ice caps and lead us into a global
cooling, while man - made CO2 continues to increase http://www.colderside.com/faq.htm).
One example I like was a relatively
recent explanation of why the Earth was warming and why the temperatures in winter were lower than average; the reason was apparently that an
ocean warmer than the atmosphere above was taking heat out of the atmosphere resulting in
cooler winter temperatures.
The apparent levelling off in the sea level rise is coincident with
recent cooler ocean surfaces.
Volcanic eruptions and El Niño events are identified as sharp
cooling events punctuating a long - term
ocean warming trend, while heating continues during the
recent upper -
ocean - warming hiatus, but the heat is absorbed in the deeper
ocean.
And, the most

cooling for more than a decade.
But that explanation is contradicted by a
recent evaluation of Arctic
Ocean heat content (Wunsch and Heimbach 2014 discussed here) which reveals the upper 700 meters of the Arctic

cooling.
«In our mor
recent global model simulations the
ocean heat - uptake is slower than previously estimated, the

cooling from aerosol emissions is lower.
Second, a series of mildly explosive volcanoes, which increased stratospheric particles, likely had more of a

When we hear «it's been
cooling since 1998» for the umpteenth time, we want to look instead at the
recent developments in climate science about

«The
recent dramatic
cooling of the average heat content of the upper
oceans, and thus a significant negative radiative imbalance of the climate system for at least a two year period, that was mentioned in the Climate Science weblog posting of July 27, 2006, should be a wake - up call to the climate community that the focus on predictive modeling as the framework to communicate to policymakers on climate policy has serious issues as to its ability to accurately predict the behavior of the climate system.
And while the study published in the journal Nature last week did not dispute manmade global warming, it did predict a
cooling from

ocean currents.
RE # 80, Steve, the trend in global
ocean temperatures would be unaffected by Lyman et al's «
