Sentences with phrase «deep ocean heat content changes»

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).

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.

Instead, they discuss new ways of playing around with the aerosol judge factor needed to explain why 20th - century warming is about half of the warming expected for increased in GHGs; and then expand their list of fudge factors to include smaller volcanos, stratospheric water vapor (published with no estimate of uncertainty for the predicted change in Ts), transfer of heat to the deeper ocean (where changes in heat content are hard to accurately measure), etc..

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).

Not all at once of course, but as mentioned above, when the PDO goes positive, we can likely expect a significant change in the atmospheric heat content as heat energy is transferred from the deep oceans back into the atmosphere.

Changes in the heat content of the deep ocean are thus far more sensitive to the air - sea thermal interchanges than previously considered.

Elsewhere on this site there is a graph of overall ocean heat content which is building indicating that while the sst is decreasing slightly the overall ocean is warming, It is likely that this overall ocean warming which has nothing to do with changes to the atmospheric temperature because it is the sea surface and not the deep ocean that is in contact with the atmosphere is what is resulting in the overall rise in atmospheric CO2 concentration which is currenly increasing at 2ppmv / year.

For global warming diagnosis, use ocean heat content changes, recognizing that the deeper ocean heating (i.e. below the long term thermocline) is mostly unavailable to affect weather on multi-decadal time periods).

Here is a figure estimating heat content changes for the decade from the 1990 ′ s to the 2000 ′ s showing that the deepest layers of the oceans have also warmed.

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.

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.

IMO the process whose changes are most likely to be responsible for apparent changes to deep ocean heat content are changes to the nature of turbulent vertical mixing in specific areas of the world, especially the West Pacific / South China Sea, and perhaps the Caribbean and Gulf of Mexico.

Advocates of the assumption that CO2 variations are a primary cause of changes in deep ocean heat content (i.e., those who author government - sponsored IPCC reports and activists for the anthropogenic global warming cause) have necessarily believed that past natural variations in deep ocean heat content are very slow and gradual.
