No doubt the southern ocean, featured strongly by Hansen et al, plays an important role, but data there are poor, and change is not well known;
in particular the recent
hiatus in global warming greatly influences any observations, which can therefore be quite misleading wrt
trends.
Kosaka and Xie made
global climate simulations
in which they inserted specified observed Pacific Ocean temperatures; they found that the model simulated well the observed
global warming slowdown or «
hiatus,» although this experiment does not identify the cause of Pacific Ocean temperature
trends.
The press release from NOAA included this statement from Karl: «Adding
in the last two years of
global surface temperature data and other improvements
in the quality of the observed record provide evidence that contradict the notion of a
hiatus in recent
global warming trends.»
Now if someone were to day, as Judith clearly did not although she had many opportunities to do so, that «concurrent with
warming of our oceans there has been a
hiatus in the significantly increasing
trend of
global surface temperatures,» then I would have not problem with the logic.
Just as importantly, he says, the model helps to explain regional
trends that seem to defy the
global warming hiatus, including record - breaking heat
in the United States last year, and the continued decline of Arctic sea ice.
Now if someone were to dsay, as Judith clearly did not although she had many opportunities to do so, that «concurrent with
warming of our oceans there has been a relatively short - term
hiatus in the
trend of significant increase
in global surface temperatures,» then I would not have a problem with the logic.

Much study has been devoted to the possible causes of a decrease
in the upward
trend of
global surface temperatures since 1998, a phenomenon that has been dubbed the
global warming «
hiatus.»
Responding to and
in the manner of KK Tung's UPDATE (and, you can quote me): globally speaking the slowing of the rapidity of the
warming, were it absent an enhanced
hiatus compared to prior
hiatuses, must at the least be interpreted as nothing more than a slowdown of the positive
trend of uninterrupted
global warming coming out of the Little Ice Age that has been «juiced» by AGW as evidenced by rapid
warming during the last three decades of the 20th Century, irrespective of the fact that, «the modern Grand maximum (which occurred during solar cycles 19 — 23, i.e., 1950 - 2009),» according to Ilya Usoskin, «was a rare or even unique event,
in both magnitude and duration,
in the past three millennia [that's, 3,000 years].»

One of the principal issues is the cause of the
hiatus in the current
global warming trend.»
And because heat can be stored
in places other than at the surface, a lack of surface
warming for a decade tells you almost nothing about the underlying long - term
warming trends... I judge that there is virtually no merit to suggestions that the «
hiatus» poses a serious challenge to the standard model [of human - caused
global warming].»
