Then they used the climate models to simulate by how much ocean heat content has risen since the 1970s.

Not exact matches

For as much as atmospheric temperatures are rising, the amount of energy being absorbed by the planet is even more striking when one looks into the deep oceans and the change in the global heat content (Figure 4).

The increase in ocean heat content is much larger than any other store of energy in the Earth's heat balance over the two periods 1961 to 2003 and 1993 to 2003, and accounts for more than 90 % of the possible increase in heat content of the Earth system during these periods.

Thus, during an El - Nino, much of the heat content of the Indo - Pacific warm pool moves from being too deep for surface measurements to detect, to being spread out on the surface of the ocean, where surface measurements can detect it.

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.

There has been that much increase in ocean heat content since 2000.)

The advantage of the ocean heat content changes for detecting climate changes is that there is less noise than in the surface temperature record due to the weather that affects the atmospheric measurements, but that has much less impact below the ocean mixed layer.

4 W / m2 seems way too high; the ocean heat content hasn't been increasing that much (or am I getting my timescales mixed up?).

One thing I would have liked to see in the paper is a quantitative side - by - side comparison of sea - surface temperatures and upper ocean heat content; all the paper says is that only «a small amount of cooling is observed at the surface, although much less than the cooling at depth» though they do report that it is consistent with 2 - yr cooling SST trend — but again, no actual data analysis of the SST trend is reported.

Some people looked at parts of that work (for example, the lower right panel of Figure 1) and point out how the climate model oceans show a smooth and pretty much unbroken increase in heat content over the historical period.

But if you google «noaa ocean heat and salt content» and compare the first two graphs («0 - 700m global ocean heat content» versus «0 - 2000m global ocean heat content») you will see that the sea SURFACE temperature is much more reflective of what is going on in the atmosphere than the oceans depths.

I don't know about all of you, but I do find that the uncertainty around e.g. the various issues related to ocean heat content or issues regarding connecting the Argo float network to other data networks is SO much better covered in Judith's bizarre and uniquely repetitive mischaracterizations of other scientists» comments, than by the published science and its critical review.

As it is, I don't care much for the overly large focus on near - surface tropospheric temperatures, as most of our weather and climate is going to be based on ocean dynamics and ocean heat content.

For as much as atmospheric temperatures are rising, the amount of energy being absorbed by the planet is even more striking when one looks into the deep oceans and the change in the global heat content (Figure 4).

The «rise rate of the ocean heat content» is much better explained by natural unforced variation.

According to the paper, «arguably, ocean heat content — from the surface to the seafloor — might be a more appropriate measure of how much our planet is warming.»

Using modern measurements of air temperature, incoming / outgoing radiation, and ocean temperature / heat content should provide much more robust techniques of climate model validation.

Thus, we suggest that scientists and modelers who seek global warming signals should track how much heat the ocean is storing at any given time, termed global ocean heat content (OHC), as well as sea level rise (SLR).

Ideally the zero point would be modulated by ocean heat content and / or ssts, since it is the comparison between energy into the oceans vs. energy radiated back out that determines warming or cooling, but we don't have much historical ohc or sst data so a fixed zero point would seem to be the best that can be done.

SST's are often, but not always, better gauges for how much heat is leaving the ocean on the way to the atmosphere rather than how much remains at depth to be measured as ocean heat content.

Essentially, Huber and Knutti take the estimated global heat content increase since 1850, calculate how much of the increase is due to various estimated radiative forcings, and partition the increase between increasing ocean heat content and outgoing longwave radiation.

I inferred from your statement that since the heat capacity of the atmosphere is small compared to «say, the oceans» that (a) it [the atmosphere] won't store much energy, and (b) as such won't change the total «heat content» of the Earth, and (c) as such won't change the Earth's temperature.

The pink shading represents simulations where greenhouse gas emissions and other human influences have been taken into account — these simulations do a much better job at tracking temperatures and ocean heat content globally and regionally.

However, the much - adjusted NODC ocean heat content data for the tropical Pacific (Figure 1) shows a decline in ocean heat content since 2000, and the ocean heat content for the Atlantic (Figure 2) has been flat since 2005.

Because you are fitting to look for a trend * after * selecting the data that looks flat, the real 95 % confidence interval of the trend in temperature (or ocean heat content) over any of these intervals is much larger than what you are presumably calculating.

Gavin, I think it would be worth adding to the post 1) the main reason why there was so much doubt about the Lyman et al results (the unphysical melt amounts for 2003 - 5), 2) the expected role of GRACE in obtaining a reliable result, 3) the fact that the ARGOs don't measure the deep oceans, and 4) that it's inappropriate to take the remaining ARGO data (shown in the Lyman et al correction to be essentially flat for the last two years) and draw any conclusions about ocean heat content trends for that period.

A lot of the southern hemisphere started warming 5000 years ago which didn't have much impact on Global «surface» but did on ocean heat content.

Q3 - Does the difference between Tangaroa and Chelle et al imply that a change in DLR does not heat the ocean as much as a similar change in DSR and, therefore, the earth's heat content sensitivity is considerably less for DLR than DSR?

Living in the real world of a real country I am much more concerned with what the 350 year temperature record is showing us, not the highly theoretical ocean heat content of a poorly measured, medium with records stretching back barely a decade.

Actually, I have concluded that ocean heat content is a much better metric to diagnose climate system heat changes (i.e. «global warming») than the surface temperature trends.

Roger Pielke Sr. has often stated that ocean heat content is a much better metric for climate change than surface temperature.

Thus in terms of impacts the problem is surface warming — which is described much better by actually measuring surface temperatures rather than total ocean heat content.
