Sentences with phrase «by upper ocean heat content»

In 2008, climate change sceptic Roger Pielke Sr said this: «Global warming, as diagnosed by upper ocean heat content has not been occurring since 2004».

Last week there was a paper by Smith and colleagues in Science that tried to fill in those early years, using a model that initialises the heat content from the upper ocean — with the idea that the structure of those anomalies control the «weather» progression over the next few years.
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.
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.
If you take the amount of crude oil extracted since 1850 (estimates vary, but maybe 200 billion tonnes = 200 * (10 ^ 9) * (10 ^ 3) kg) and multiply by the energy density of crude oil (~ 50MJ / kg) the result comes out at about 10 ^ 22 J which is an order of magnitude lower than the increase in ocean heat content in the upper 700m since the 1950s (~ 10 ^ 23J).
In the present study, satellite altimetric height and historically available in situ temperature data were combined using the method developed by Willis et al. [2003], to produce global estimates of upper ocean heat content, thermosteric expansion, and temperature variability over the 10.5 - year period from the beginning of 1993 through mid-2003...
But that explanation is contradicted by a recent evaluation of Arctic Ocean heat content (Wunsch and Heimbach 2014 discussed here) which reveals the upper 700 meters of the Arctic Ocean have been cooling.
At that point you try and measure changes in heat content of the upper ocean, more precisely, the flow of energy into and out of the upper ocean by measuring the change in heat content over time.
The argument that this change it is somehow driven by energy reservoirs in the deep ocean is clearly flawed: the deep ocean would be * cooling * as it lost energy to the upper ocean, but deep ocean heat content is increasing at the same time as OHC in the upper ocean is increasing.
These trends are also accompanied by rising sea levels and upper ocean heat content over similar multi-decadal time scales in the tropical Atlantic.
We also find that H is predicted with significantly more skill by DePreSys than by NoAssim (Fig. 1B), and we conclude that the improvement of DePreSys over NoAssim in predicting Ts on interannual - to - decadal time scales results mainly from initializing upper ocean heat content.
