The westerlies in the Northern Hemisphere, which

as the water gets hotter), sea - level rise due to thermal expansion, and the amount of water vapour in the 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.
Purely physical processes like wind - driven mixing can
increase the uptake of CO2 by the
oceans, but biological processes also play an important role,
as does the
temperature difference between the air and the water:
[1] CO2 absorbs IR, is the main GHG, human emissions are
increasing its concentration in the atmosphere, raising
temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts
as a feedback; since the
oceans cover so much of the planet, water is a large positive feedback; melting snow and ice
as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the
temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are
increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders
increase the amplitude and duration of blocking highs,
increasing drought and extreme
temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)
All else equal, if CO2 goes up, it affects that balance, and
temperature increases until a new equilibrium is reached (which takes a long time
as the
ocean is a big heat sink).
How does society,
as it stands now, not understand that they have locked into the system already a rise to the high 500's ppm, and, in my humble opinion, the low 600's are NOT out of the question.To me this is just
as much of a tragedy if it takes place 250 years from now
as it is if it takes only 100 years.In the end, the seventh generation is screwed by a huge loss of fresh water, a huge
increase in
temperature, an
ocean that no longer produces even one tenth of its total protein and carboydrate output
as it did in the 1800's.
«The current evidence strongly suggests that: (a) hurricanes tend to become more destructive
as ocean temperatures rise, and (b) an unchecked rise in greenhouse gas concentrations will very likely
increase ocean temperatures further, ultimately overwhelming any natural oscillations.»
Ok, now the next problem seems to be that the deep
ocean would come into the act, and
as the surface
temperature began to catch up,
as with
ocean surface
temperature, we should then expect significant hurricane activity, and otherwise
increased storm conditions.
If
as a result of physical processes (such
as El Nino) warmer water reaches the surface of the
ocean, so less heat is conducted from the atmosphere into the
ocean and the atmopsheric
temperature will therefore
increase — on a much shorter — comparatively instantaneous — timescale.
Moreover, the
ocean (which has been responsible for absorbing
as much
as 80 % of anthropogenic emissions) can become saturated, or
as temperatures rise in the temperate regions or winds
increase in arctic regions and stir up carbon dioxide from below, act
as an emitter.
As atmospheric temperatures increase, therefore, heat transfer into the oceans increases as the system tends towards a new equilibrium temperatur

2) Anthropogenic global warming will not affect the Arctic (or any other region) solely by
increasing local

Failures in the Earth system are already beginning to occur in a number of ways at a GMT
increase of only 0.8 oC; GMT does not address huge regional differences in
temperature increase; a
temperature target doesn't even address
ocean acidification; and we are frittering our time here (and in numerous scientific papers) addressing 2oC
as if it is a reasonable target???
then would
increase the heat flow atmosphere - >

Now since relative humidity remains roughly constant at the
ocean surface and the air's capacity to hold water
increases with
temperature, relative humidity will actually decrease over land, particularly
as one enters the continental interiors.
