Warm ocean surface temperatures are shown in red, cooler waters in blue.
This is seen occurring naturally, especially in association with
warm ocean surface in connection with the El Nino Southern Oscillation.
Decrease in sea ice and snow cover are the prime causes, energy being used to melt ice and
warm the ocean surface waters.
Hybrid storms and climate change: Sandy, continues Emanuel, is a «hybrid storm» — in other words, it has characteristics of tropical cyclones (hurricanes) that get their energy from
the warm ocean surface, but also of winter cyclones that get their energy from temperature contrasts in the atmosphere.
As mentioned above, hurricanes feed and grow on
warm ocean surface waters.
A regional climate model study examines the influence of
warm ocean surface temperatures in the eastern tropical Atlantic in summer to see what an increase of a few degrees Celsius does to rainfall.
Characterized by unusually
warm ocean surface temperatures
Just as it is officially predicted that CO2 - driven warming will be greatest in the upper air, which will in turn warm the surface, so it is predicted that the near - surface air will
warm the ocean surface, which will warm the deeps.
(I think that an anomalously
warm ocean surface heated from below would lead to more evaporation, and the additional water vapor would give a positive greenhouse effect that would partially offset the effect of a drop in greenhouse gas concentrations.)
Warmer air can carry more moisture, which can lead to more extreme rainfall events, and
warmer ocean surface temperatures are known to intensify the most powerful hurricanes.
Terrestrial hurricanes are powered by heat released from
warm ocean surfaces.
The thermal gradient through this layer dictates the rate of heat loss from the (typically)
warmer ocean surface, to the cooler atmosphere above.
Soundbite version: «Global warming is expected to increase sea surface temperatures, create a thicker and
warmer ocean surface layer, and increase the moisture in the atmosphere over the oceans — all conditions that should lead to a general increase in hurricane intensity and maybe frequency.»
After relatively cooler ocean surface years, the increase is small, and after relatively
warmer ocean surface years, the increase is large.
eadler replied, «It seem to me that you claim that
a warmer ocean surface will make the heat content of the ocean increase even more.
As you say, the net flow of energy is always between
a warmer ocean surface and a colder atmosphere.
Previous research has also shown that
warmer ocean surface temperatures fuel more powerful storms.
Before you say it's the back radiation, I have to tell you that radiation from colder regions does not penetrate
the warmer ocean surface more than a few nanometres.
Forgive me if «net feedback strength» absorbed in the less than human hair thickness of
the warmer ocean surface does not impress.
The warmer ocean surface temperatures impact corals and alter coral reef communities by prompting coral bleaching events and altering ocean chemistry.
THERE HAS BEEN A WARMING TREND FROM THE 70s THRU THE LATE 90s,... accompanied by other changes tied to a warming trend (record low arctic sea ice extent & thickness, retreating glaciers, retreating snow lines,
warming ocean surface temps, increases in sea height, de-alkalinizing oceans).
AGW proponents accept that the virtual cessation of warming over the past 13 years (Figure 3) is a result of cooler ocean surfaces but refuse to accept the corollary that the primary cause of the warmer period was
warmer ocean surfaces.
d) That although
warmer ocean surfaces absorb less CO2 the observed increase in CO2 in the air is all or mostly our fault.
e) That
a warmer ocean surface increases the surface / space temperature differential yet does not give rise to a significant increase in loss of energy to space.
If you still think a cold atmosphere can warm a (much)
warmer ocean surface (let alone the DEEP oceans),
When four hurricanes of extraordinary strength tore through Florida last fall, there was little media attention paid to the fact that hurricanes are made more intense by
warming ocean surface waters.
If you still think a cold atmosphere can warm a (much)
warmer ocean surface (let alone the DEEP oceans), I'm afraid you will believe anything as long as it has the «peer - reviewed» stamp on it.
It simply isn't conceivable that a mere 55 % of human emissions, (after deducting the so called airborne fraction) offsets the entire absorption changes caused globally and naturally by
warmer ocean surfaces.
That is what happens when oceans naturally increase their emission of energy and the response of the air is exactly the same whether
the warmer ocean surface is a result of enhanced energy emission from the ocean or enhanced energy in the air from another cause such as more humidity or more CO2.
Warmer ocean surfaces send them poleward.
Furthermore
warm ocean surfaces really do send the air circulation systems poleward whilst changes in the intensity of the polar high pressure cells work in opposition to those oceanic effects.
More solar energy increases the speed of processes in the biosphere and thus the carbon cycle and by
warming the ocean surface reduces it's ability to absorb CO2.
Thus the more energy from the sun the faster the hydrological cycle will run with
warmer ocean surfaces, more zonal and / or more poleward jets and a faster expulsion of energy to space.
Not exact matches
While this is bad news for the planet, it's good news for climate change scientists who have — for the last two decades — puzzled over
warming trends in
ocean surface temperatures for nearly 20 years.
According to a big chunk of
ocean surface temperature recorded by boat, the
oceans were not
warming nearly as quickly as the rest of the planet.
Evidence from the National Aeronautics and Space Administration (NASA) shows that global sea levels in the last two decades are rising dramatically as

El Niño is an abnormal periodic
warming of
surface ocean water off the Pacific coast of South America.
The floods have been triggered by the weather event known as El Nino, a
warming of
surface temperatures in the Pacific
Ocean that wreaks havoc on weather patterns every few years.
The Atlantic
Ocean surface circulation is an important part of the Earth's global climate, moving
warm water from the tropics towards the poles.
Those weather patterns are linked to
warmer surface temperatures in the Pacific and Atlantic
oceans, respectively, and correlated with the timing of observed floods on the lower Mississippi.
While it is still possible that other factors, such as heat storage in other
oceans or an increase in aerosols, have led to cooling at the Earth's
surface, this research is yet another piece of evidence that strongly points to the Pacific
Ocean as the reason behind a slowdown in
warming.
Rich wildlife at this Southern
Ocean island faces
surface waters 1.8 degrees F
warmer in winter and 4.1 degrees F
warmer in summer than they were 80 years ago
Gerald Meehl, a climate scientist at the National Center for Atmospheric Research who was also an author on the paper, said this research expanded on past work, including his own research, that pointed to the Interdecadal Pacific Oscillation as a factor in a
warming slowdown by finding a mechanism behind how the Pacific
Ocean was able to store enough heat to produce a pause in
surface warming.
The cycle of Pacific
Ocean surface water
warming and cooling has become more variable in recent decades, suggesting El Niño may strengthen under climate change
When
ocean cycle shifts, globe is likely to
warm up When climate models were run that included the stronger winds, they were able to reproduce the slowdown in
surface temperatures.
They identified wind patterns that mixed the
warmer surface and colder deep waters to cool the
ocean's
surface and reduce the intensity of the storm.
And around Antarctica, where even the
surface ocean water is already quite cold and dense, some of that water in the
ocean depths, which is also carbon rich, eventually
warmed enough so that it became less dense than the water above it.
Higher sea

warm water, dubbed «The Blob,» that appeared in the northern Pacific
Ocean more than two years ago.
The finding surprised the University of Arizona - led research team, because the sparse instrumental records for sea
