And a few months ago, a study with a high - resolution
ocean model appeared, suggesting that the meltwater from Greenland is likely to weaken the AMOC considerably within a few decades (Böning et al. 2016 — as we reported).
Not exact matches
«Antarctica: Return of the Weddell polynya supports Kiel climate
model: After 40 years, a large ice - free area
appears again in the Southern
Ocean in mid-winter.»
Your statement that «Thus it is natural to look at the real world and see whether there is evidence that it behaves in the same way (and it
appears to, since
model hindcasts of past changes match observations very well)» seems to indicate that you think there will be no changes in
ocean circulation or land use trends, nor any subsequent changes in cloud responses thereto or other atmospheric circulation.
That matters because the trickiest part of global climate
models appears to be how they handle
ocean - atmosphere interactions, and I really have no idea how well they link changes in local wind - driven upwelling to the net thermohaline circulation.
And the
oceans appear to explain why the observed temperatures have fallen below the
model median expectations.

2) It
appears to me that the GISS - E2 - R are atmospheric /
ocean model runs, while the HadISST is purely SST.
From interviews and postings I've read by Trenberth, it
appears that he wants the
oceans to be a deus - ex-machina, explaining The Pause now that it's exceeded the «easily up to 15 years in length» pauses he perceives in climate
models.
In the climategate emails it was also noted that scientists conspired on both sides of the Atlantic to adjust historic
ocean temperatures to make them
appear more like their flawed climate
models.
Manabe included a more detailed
ocean model which
appears to be more correct.
For a method for that, may I encourage you to look at Roy Spencer's recent
model on thermal diffusion in the ocean: More Evidence that Global Warming is a False Alarm: A Model Simulation of the last 40 Years of Deep Ocean Warming June 25th, 2011 See especially his Figure Forcing Feedback Diffusion Model Explains Weak Warming in 0 - 700 m layer as Consistent with Low Climate Sensitivity His model appears to be more accurate than the IP

«Much of our confidence stems from the fact that our
model does well at predicting slow changes in
ocean heat transport and sea surface temperature in the sub-polar North Atlantic, and these
appear to impact the rate of sea ice loss.
Since latent heat transport (and surface cooling of the
ocean) must increase in proportion to the rate of evaporation, perhaps Wentz et al have identified a reason why the
models appear to overstate climate sensitivity: the actual latent cooling increases by about 4 watts per square meter more than the
models predict for each degree rise in surface temperature.
A small random eddy in the real
ocean can grow and
appear out of nowhere as far as a forecasting
model is concerned, and make something of a dog's breakfast of the forecast from that time on.
Using global climate
model simulations that replicated the
ocean basins and landmasses of this period, it
appears that changes in
ocean circulation due to warming played a key role.
I have seen a number of statistical
models of surface temperatures which
appear to achieve good fits using explanatory variables which play little role, if any, in the coupled
ocean and atmospheric
models that the IPCC relies on.
In a follow - up study, which
appeared in the Journal of Climate (2001), NOAA scientists Knutson and Tuleya teamed up with Isaac Ginis and Weixing Shen of the University of Rhode Island to explore the climate warming / hurricane intensity issue using hurricane
model coupled to a full
ocean model.
That's a key reason surface temperatures haven't
appeared to warm as fast as many had expected in the past ten years — although
ocean warming has sped up, and sea level rise has accelerated more than we thought, and Arctic sea ice has melted much faster than the
models expected, as have the great ice sheets in Greenland and Antarctica
It
appears from SKS that rather than the atmosphere currently warming as predicted by the majority of
models, it is the
oceans that are rapidly heating.
