Not exact matches

While the TOA observations show far less agreement with the NODC and Hadley Centre OHC data sets, after 2004 they demonstrate moderate agreement with PMEL / JPL / JIMAR data sets (as determined by statistical analysis).

You may claim my comments are veering «off topic», but I am supporting the use of OHC as a metric and showing how climate models get it wrong.

This plot shows thermosteric sea level change over that period, which would strongly correlate with OHC / ocean temperature, and this plot shows surface temperature evolution.

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.

According to the graphs he presents on his blog - o - site, in his favorite Case III version 0 - 50m OHC has been dropping while Levitus shows it rising.

What I have shown in those posts is that the rise in OHC from 1955 to present can be explained by natural factors that have resulted in upward shifts in OHC, not a monotonous rise.

The entire OHC content anomaly when converted from Joules back to temperature in the ocean is on the order of 0.09 C (I assume you can do the math and conversion, but if not let me know and I'll show my work).

The five ensemble members of the ORAS4 ocean reanalysis OHC for 0 — 700m and full - depth ocean are shown, where they have been aligned for 1980 to 1985, in 1022 J.

Sidd @ # 30 But the OHC graphs at your link show a slope of 13.2 e21J per year from 1990 to 2008 plus you have an extra bit at greater depth (I suppose ~ 14e21J total).

So unless and until someone shows that my argument in that post is wrong, I plan to continue to treat the OHC figures as interesting, but purely anecdotal.

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.

The data also show that failing to account for increases in deep OHC is a problematic omission.

The OHC graph shows a slow warming of the ocean, which is a sign of the positive and sustained imbalance.

The OHC integrates the radiative imbalance making it a much less noisy quantity than instantaneous fluxes you keep wanting to show.

OHC follows changes in TOA radiant flux as shown in the Wong et al 2006 paper — ocean / atmosphere heat transfer obviously occurs but the fundamental metric is at TOA.

If OHC is increasing at about 0.7 W / m ^ 2 (for the top 2000 meters) and the SST is showing an anomaly of 0.6 C, then the incoming heat is increasing at a rate of 2.3 W / m ^ 2.

Go ahead and show us on any of the following: Arctic Sea Ice Extent Antarctic Sea Ice Extent OHC Sea level Rise Rate Global Temperature Drought Incidence Hurricane Activity Tornado Activity Glacial Melting Like my mother use to tell me «Do something useful»

A comparison of the changes and fluctuations in the three observational climate indicators (SLR, OHC, and GMST; Figure 2) clearly shows that both OHC and SLR are much better indicators of global warming than GMST.

Studies show that taking the full ocean depth, ice melt, and other factors into account, Earth is estimated to have gained 0.40 ± 0.09 W m − 2 since 1960 and 0.72 W m − 2 since 1992 [Cheng et al., 2017]-- 18 % higher than for the top 2,000 - meter OHC alone.

What this means is that OHC before 2003 is essentially unreliable; Knox and Douglass confirmed this by showing a correlation between OHC, Fohc, and OLR, Ftoa; before 2003, the correlation between Fohc and Ftoa was poor, after 2003 it is good.

This shows the consistency of the Wong et al TOA record with OHC — as noted by IPCC s 3.4.4.1.

Loeb 2012 shows that ENSO is responsible for the interannual variability, but not the increase in OHC over the last few decades.

So, which models are we talking about, and what values do they show when it comes to hindcasting and forecasting OHC, TOA net SW radiation, TOA net LW radiation and changing lapse rate?

The only two ocean basins with major increases in OHC during the ARGO era are the South Atlantic and the Indian Oceans, while the North Atlantic, Arctic, and South Pacific Oceans show significant declines in OHC.

Since 1Q2004, the OHC data show a positive trend of +3.1 ZJ / yr for the 0 - 700 m region.

I have illustrated and document that there are multiyear aftereffects of ENSO events that cause the positive trends in SST and TLT anomalies outside of the tropical Pacific, and I have shown that the rise in global OHC, when broken down into logical ocean basin subsets, is dominated by natural variables.

Recent ocean heat content (OHC) calculations have shown a dramatic shift during the period 2001 — 2003, which is nearly coincident with a major transition in the ocean observation network from a ship - based system to Argo floats.

Rob on the other hand shows there is significant changes to OHC from clouds.

I showed that the height of the water column of the tropical Pacific reflected the same rise as the 1995/96 OHC, countering your inference that a pocket of warm water rose up from below the 700 meter depth in the tropical Pacific.

From the paper: Over the whole globe, the dominant spatial mode of variability in OHC in the upper 300 m [as shown by the first empirical orthogonal function (EOF), which explains the most variance], occurs mainly in the tropical Pacific and has the structure of ENSO variability (Fig. 4, A and B).

Figure 4, C and D, shows that the dominant OHC variability below 300 m occurs mainly in the Atlantic basin and the Antarctic Circumpolar Current (ACC) region.

In contrast, the observed data on OHC show that most (far more than half) of the warming must have been forced, and excludes more than a minor role for internal variability.

Ocean Heat Content estimates produced by the ex-NODC at NCEI show that OHC anomalies in each quarter of 2015 were the highest on record for each quarter.

lolwot, where's the empirical evidence showing that this is in fact the mechanism that's been responsible for the increase in global OHC since 2001?

Denier sites use the NODC OHC data as it shows a mini-trend of cooling.

ARGO showed ocean cooling but when that didn't jibe with OHC datasets constructed without ARGO then the ARGO data was pencil whipped into agreement.

As you know, some contrarians / deniers are capitalizing on the fact that the recently adjusted NODC 0 - 700m OHC data have shown a small negative slope since 2003 or so (yes, it is not a stat.

Hence, the OHC integrated down to 700 m shows some slowdown, but the implication is that the missing heat is being deposited mainly in the region below 700 m depth.

However, the upper OHC for the top 275 m shows the same stasis as for the surface temperature (Fig. 7), in fact for this example the OHC (0 — 275 m) actually decreases.

The lower panel shows the perturbation relative to mean from 2005 to 2015 in OHC (O E) for layers 0 — 275, 0 — 700 m depth, and for the entire column to the bottom of the ocean in 1022 J.

Lynn, I find the best argument against any of the «pause, hiatus,» types is to show a graph of ocean heat content — like NOAA's.0 to 700m or 0 to 2000 m OHC products
