In extreme conditions — in this case, magma -
heated water
at an
ocean depth of nearly 10,000 feet — things work a little differently.

«It helps to modulate the climate by transferring
heat from the equator to the poles,» said coauthor Christina Ravelo, professor of

One question that has long and intensively been discussed in research is: Where and how deep does seawater penetrate into the seafloor to take up
heat and minerals before it leaves the
ocean floor
at hydrothermal vents?
In the North Atlantic, more
heat has been retained
at deep levels as a result of changes to both the
ocean and atmospheric circulations, which have led to the winter atmosphere extracting less
heat from the
ocean.
A previous paper by Garrick - Bethell and some of the same coauthors described the effects of tidal stretching and
heating of the moon's crust
at a time 4.4 billion years ago when the solid outer crust still floated on an

Because these waves are involved in
ocean mixing and thus the transfer of
heat, understanding them is crucial to global climate modeling, says Tom Peacock, a researcher
at the Massachusetts Institute of Technology.
Climate models do not predict an even warming of the whole planet: changes in wind patterns and
ocean currents can change the way
heat is distributed, leading to some parts warming much faster than average, while a few may cool,
at least
at first.
These currents are driven by winds,
ocean temperature and salinity differences, and are efficient

With the sun continuing to
heat the
ocean water
at the tropical latitudes regardless of ice cap conditions up north, it would seem that the presence of an ice cap would result in a warmer

However, radiation changes
at the top of the atmosphere from the 1980s to 1990s, possibly related in part to the El Niño - Southern Oscillation (ENSO) phenomenon, appear to be associated with reductions in tropical upper - level cloud cover, and are linked to changes in the energy budget
at the surface and changes in observed
ocean heat content.

The observed fact that temperatures increases slower over the
oceans than over land demonstrates that the large
heat capacity of the
ocean tries to hold back the warming of the air over the

This is not only in excellent agreement with the observed temperature changes
at the surface (blue stars), it also correctly reproduces the observed
heat storage in the
oceans — a strong indicator that the model's
heat budget is correct.
When greenhouse gases increase, more longwave radiation is directed back
at the
ocean surface, which warms the cool - skin layer, lowers the thermal gradient, and consequently reduces the rate of
heat loss.
In Earth's
oceans, that sort of
heating shows up
at sites known as hydrothermal vents.
«The reason this study is so exciting is that previous methods of reconstructing

Aside from the fact that there's no physical support from such a picture, this state of affairs is highly unlikely because you'd still have to account for things like the way the system responds to CO2

heat into the upper
ocean, and so forth.
