[2] This, in turn, could have driven the higher rate of increase in ocean
heat content shown in [1].

He agrees that the Increase in ocean
heat content shows that the earth has continued to gain energy during the so called «pause» or «hiatus».
Balmaseda et al. (2013) suggested that changes in the winds have resulted in a recent heat accumulation in the deep sea that has masked the surface warming and that the ocean
heat content shows a steady increase.
This is vividly demonstrated in the following graph which shows surface temperature jumping up and down from year to year while the Earth's total
heat content shows a steady, near - monotonic increase.

The biggest increases in ocean
heat content were in those deeper layers,
showing «that the deep ocean has played an increasingly important role in the ocean energy budget since 1998,» according to the study.
Figure 5.1
shows two time series of ocean
heat content for the 0 to 700 m layer of the World Ocean, updated from Ishi et al. (2006) and Levitus et al. (2005a) for 1955 to 2005, and a time series for 0 to 750 m for 1993 to 2005 updated from Willis et al. (2004).
However, the large - scale nature of
heat content variability, the similarity of the Levitus et al. (2005a) and the Ishii et al. (2006) analyses and new results
showing a decrease in the global
heat content in a period with much better data coverage (Lyman et al., 2006), gives confidence that there is substantial inter-decadal variability in global ocean
heat content.
The time series
shows an overall trend of increasing
heat content in the World Ocean with interannual and inter-decadal variations superimposed on this trend.
We assess the
heat content change from both of the long time series (0 to 700 m layer and the 1961 to 2003 period) to be 8.11 ± 0.74 × 1022 J, corresponding to an average warming of 0.1 °C or 0.14 ± 0.04 W m — 2, and conclude that the available
heat content estimates from 1961 to 2003
show a significant increasing trend in ocean
heat content.
The geographical distribution of the linear trend of 0 to 700 m
heat content for 1955 to 2003 for the World Ocean is
shown in Figure 5.2.
Examination of the geographical distribution of the differences in 0 to 700 m
heat content between the 1977 — 1981 and 1965 — 1969 pentads and the 1986 — 1990 and 1977 — 1981 pentads
shows that the pattern of
heat content change has spatial scales of entire ocean basins and is also found in similar analyses by Ishii et al. (2006).
Observed changes in ocean
heat content have now been
shown to be inconsistent with simulated natural climate variability, but consistent with a combination of natural and anthropogenic influences both on a global scale, and in individual ocean basins.
**** Since alpha - lactalbumin lacks the special glutathione - boosting bonds possessed by BSA and beta - lactoglobulin, its greater
heat - stability suggested by this study is consistent with the research I cited in «Biochemical Magic»
showing that
heat treatment not only depletes the total whey protein
content of milk, but also renders the remaining whey protein less capable of boosting glutathione status.
But recent studies also
show that the phytonutrient
content of EVOO — including its phenolic compounds like hydroxytyrosol and its flavonoids like luteolin — are not stable to
heat and degrade relatively quickly.
Studies
show that the
heat from baking doesn't effect the omega - 3

The bottom icon will allow you to switch the news

The key observation here is the increase in ocean
heat content over the last half century (the figure below
shows three estimates of the changes since 1955).
You speak of

It
shows heat content increases and freshwater

The ocean
heat content analysis by Barnett (and in other groups)
show that the changes are most consistent with the GHGs becoming increasingly dominant over this time.
In Balmaseda et al. paper, they
show very nicely the changes in the ocean
heat content (OHC) since the late 1950s and how during the last decade the OHC has substantially increased in the deep ocean while in the first 300 and 700 meters it has stalled.
This is supported by historic observations (Figure 1), which
shows roughly decade - long hiatus periods in upper ocean
heat content during the 1960s to 1970s, and the 1980s to 1990s.
Previous work by Barnett's group
showed that coupled models when forced with greenhouse gases did give ocean
heat content changes similar to that

You may now understand why global temperature, i.e. ocean
heat content,
shows such a strong correlation with atmospheric CO2 over the last 800,000 years — as
shown in the ice core records.
And yet, when you do trends of global data you are averaging air temperatures over intervals where the
heat content is not continuous, and thus the trend that is the average temperature does not
show the actual trend of the
heat content.
This study
showed that the predictability of La Niña duration is controlled by the magnitude of initial oceanic
heat content anomalies driven by the preceding El Nino.
The chart
shows that starting in the late 1940's, we have been able to measure the
heat content of the top 2000 meters of ocean accurately enough so that annual changes in ocean
heat content of less than 1e22 joules can be detected and tracked.
This is at least ten additional years compared to the majority of previously published studies that have used the instrumental record in attempts to constrain the ECS.We
show that the additional 10 years of data, and especially 10 years of additional ocean
heat content data, have significantly narrowed the probability density function of the ECS.
Data from Church et al. (2011) recently updated this picture,
showing that total global
heat content continues its steady climb upwards.
For example, as discussed in Nuccitelli et al. (2012), the ocean
heat content data set compiled by a National Oceanographic Data Center (NODC) team led by Sydney Levitus
shows that over the past decade, approximately 30 percent of ocean
heat absorption has occurred in the deeper ocean layers, consistent with the results of Balmaseda et al. (2013).
Increasing ocean
heat content also
shows no recovery of Arctic sea ice anywhere in the cards.
Ultimately our paper
shows that all three of the main conclusions in DK12 are faulty: the rate of OHC increase has not slowed in recent years, there is no evidence for «climate shifts» in global
heat content data, and the recent OHC data do not support the conclusion that the net climate feedback is negative or that climate sensitivity is low.
