Naturally occurring interannual and multidecadal shifts in regional ocean regimes such as the Pacific El Niño - Southern Oscillation, the North Atlantic Oscillation, and the Atlantic Multidecadal Oscillation, for example, are bimodal oscillations that cycle between phases of warmer and cooler sea surface temperatures.

First, I thought a warming climate reduced the temperature difference between the equator and poles, which is what drives most of the winds and ocean currents that cause ocean mixing.

The diagnostics, which are used to compare model - simulated and observed changes, are often simple temperature indices such as the global mean surface temperature and ocean mean warming (Knutti et al., 2002, 2003) or the differential warming between the SH and NH (together with the global mean; Andronova and Schlesinger, 2001).

Ancient crocodiles colonized the seas during warm phases and became extinct during cold phases, according to a new study, demonstrating a link between crocodile evolution and ocean temperature.

So the mechanism should cause a decline in skin temperature gradients with increased cloud cover (more downward heat radiation), and there should also be a decline in the difference between cool skin layer and ocean bulk temperatures - as less heat escapes the ocean under increased atmospheric warming.

Increased warming of the cool skin layer (via increased greenhouse gases) lowers its temperature gradient (that is the temperature difference between the top and bottom of the layer), and this reduces the rate at which heat flows out of the ocean to the atmosphere.

Kevin, even with greater evaporation, when one considers all the energy fluxes into and out of the ocean cool skin layer, as long as the change in net energy flux causes the cool skin to warm, the temperature gradient between the cool skin layer and the bulk ocean below it will decrease.

ENSO events, for example, can warm or cool ocean surface temperatures through exchange of heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the radiative balance in the lower atmosphere).

A sea breeze, which is caused by the temperature and pressure difference between warm areas inland and the cool air over the ocean, often develops on warm summer days as well, increasing the on - shore flow pattern and maintaining a constant flow of marine stratus clouds onto the coastal areas.

Surface temperature is an imperfect gauge of whether the earth has been warmed by an imbalance between incoming radiation from the sun, and outgoing radiation, because of the role of ocean currents in the distribution of heat between deeper and surface waters.

Though hurricanes strenthen when moving over warmer water, this is merely due to the fact that the horizontal temperature gradient of the atmosphere is not as steep, i.e. the temperature differential between the water and the atmosphere increases as the storm hits tropical waters; it is not the ocean temperature per se that drives the hurricane.

This is because, in this region, wind power depends on the temperature difference between the land and the sea, and previous research has shown that warming occurs faster on land than above oceans.

While there are some similarities between the approaches, an important difference is that the slab - ocean approach allows surface and MBL temperatures to adjust to the energetic perturbation: positive energetic forcing of the surface leads to warming, weakens the inversion, and reduces low - cloud cover and liquid water path (LWP).

And for the period of 1997 to 2012, there are no similarities between the warming and cooling patterns for lower troposphere temperatures over the oceans and the satellite - enhanced sea surface temperature data.

By comparing modelled and observed changes in such indices, which include the global mean surface temperature, the land - ocean temperature contrast, the temperature contrast between the NH and SH, the mean magnitude of the annual cycle in temperature over land and the mean meridional temperature gradient in the NH mid-latitudes, Braganza et al. (2004) estimate that anthropogenic forcing accounts for almost all of the warming observed between 1946 and 1995 whereas warming between 1896 and 1945 is explained by a combination of anthropogenic and natural forcing and internal variability.

In his recently published study in the journal Nature, Temperatures blown off course, he explains how unprecedented trade winds have shifted heat into the ocean thermocline - between 100 metres and 300 metres - and that this is the primary cause of the global warming pause.

There is some correlation between changes in temperature due to global warming in different parts of the ocean, so there might be some reduction below 0.1 C, but how much and how has it been measured?

We know there is a link between warming oceans, warmer ocean temperatures, and the power of a storm like Harvey.

Much of the warming, he says, stems from fluctuations in temperature that have occurred for millions of years — explained by complicated natural changes in equilibrium between the oceans and the atmosphere — and the latest period of warming will not result in catastrophe.

«The authors write that «the El Niño - Southern Oscillation (ENSO) is a naturally occurring fluctuation,» whereby «on a timescale of two to seven years, the eastern equatorial Pacific climate varies between anomalously cold (La Niña) and warm (El Niño) conditions,» and that «these swings in temperature are accompanied by changes in the structure of the subsurface ocean, variability in the strength of the equatorial easterly trade winds, shifts in the position of atmospheric convection, and global teleconnection patterns associated with these changes that lead to variations in rainfall and weather patterns in many parts of the world,» which end up affecting «ecosystems, agriculture, freshwater supplies, hurricanes and other severe weather events worldwide.»»

A new study on ice loss in Antarctica by the British Antarctic Survey confirms what we already know about the effects of global warming but it differentiates between the effects of ocean currents, their cause and the air temperature effects at the ice surface.

These are supposedly three independent temperature sets, with an ocean between, but obviously they have been doctored in unison to create a non-existent warming.

In the case of warming, the lag between temperature and CO2 is explained as follows: as ocean temperatures rise, oceans release CO2 into the atmosphere.

Actually Fielding's use of that graph is quite informative of how denialist arguments are framed — the selected bit of a selected graph (and don't mention the fastest warming region on the planet being left out of that data set), or the complete passing over of short term variability vs longer term trends, or the other measures and indicators of climate change from ocean heat content and sea levels to changes in ice sheets and minimum sea ice levels, or the passing over of issues like lag time between emissions and effects on temperatures... etc..

From the paper: «The results also 1) reveal a significant level of coupling between ocean and land temperatures that remains even after the effects of ENSO and volcanic eruptions have been removed; 2) serve to highlight the improvements in the quality of the time series of global - mean land temperatures with the increase in the areal coverage of the station network from 1951 onward; and 3) yield a residual time series in which the signature of anthropogenically induced global warming is more prominent.»

Over ocean stretches with a positive SST anomaly air convection is higher (as the temperature difference between the warm sea surface and the cool air higher up in the troposphere is greater), so a higher likelihood for the formation of depressions exists and more precipitation is to be expected.
