[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?)

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

Heat can change ocean dynamics and eventually will increase glacial melting, which is mainly responding to subsurface water rather than air warming.

Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to reflect the sun's energy, increasing surface reflectivity and altering the amount or characteristics of clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level rise by increasing land storage of water, protecting ice sheets or artificially enhancing mountain glaciers).

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.

Think of what would happen if you could pump cold deep water up to the surface, increasing the air / sea temperature gradient and warming the water; that would give you an anomalously large ocean heat uptake.

But the evidence of a connection between warming ocean waters and greenhouse gas increases is compelling and consistent with theory and observations.

There is so little understanding about how the ocean parses its response to forcings by 1) suppressing (local convective scale) deep water formation where excessive warming patterns are changed, 2) enhancing (local convective scale) deep water formation where the changed excessive warming patterns are co-located with increased evaporation and increased salinity, and 3) shifting favored deep water formation locations as a result of a) shifted patterns of enhanced warming, b) shifted patterns of enhanced salinity and c) shifted patterns of circulation which transport these enhanced ocean features to critically altered destinations.

Consenquently, the associated SST pattern is slightly cooler in the deep convection upwelling regions of the Equitorial Pacific and the Indian Ocean, strongly cooler in the nearest deep convection source region of the South Atlantic near Africa and the Equator, warm over the bulk of the North Atlantic, strongly warmer where the gulf stream loses the largest portion of its heat near 50N 25W, and strongly cooler near 45N 45W, which turns out to be a back - eddy of the Gulf Stream with increased transport of cold water from the north whenever the Gulf Stream is running quickly.

However, at the same time, there's been the steady increase in subtropical ocean surface temperatures in the Atlantic Warm Pool, leading to record water temperatures off the US east coast in winter, which tends to fuel more extreme storms (via the increase in water vapor pressure over the warmer ocean).

So does the warming of the ocean, or for that matter, even the water vapor feedback as the increasing partial pressure water vapor is both a response to higher temperatures and a cause of higher temperatures — but can raise temperatures only against the thermal inertia of the ocean.

and how about nasa's recent report of the apparent arctic ocean gyre reversal to clockwise that is underway — that the counterclockwise gyre of the arctic ocean rotation (since 1989) which apparently also been largely responsible for centrifigally pushing arctic ice into warmer waters, speeding melting — should now predictably result in increasing amounts of ice due to the centripetal pull of the ice toward the north pole?

Consider the possibility that not just millions, but billions face disastrous consequences from the likes of (including but not limited to): Sandy (and other hybrid and out - of - season storms enhanced by the earth's circulatory eccentricities and warmer oceans); the drought in progress; wildfires; floods (just last week, Argentina had 16 inches of rain in 2 hours *); derechos; increased cold and snow in the north as the Arctic melts and cracks up, breaking up the Arctic circulation and sending cold out of what was previously largely a contained system, and losing its own consistent cold, seriously interfering with the Jet Stream, pollution of multiple kinds such as in China, the increase of algae and the like in our oceans as they heat, and food and water shortages.

Increased melting in the warmer summer is causing the internal drainage system of the ice sheet to accommodate more melt - water, without speeding up the flow of ice toward the oceans, the journal Nature reports.

The increased area of warm water on the surface allows the tropical Pacific Ocean to discharge more heat than normal into the atmosphere through evaporation.

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.

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..

There is absolutely no reason to believe that this effect will do anything but get stronger from here on as the vast «crops» of oceanic bacteria adapt to both warmer ocean waters and increased CO2 and nutrient levels and simply increasingly cool the global atmospheric climate simply by «growing faster»!

Rising temperatures are warming ocean waters, which expand as the temperature increases.

Hurricanes draw their energy from the ocean and warmer waters provide an increase in both temperature and moisture content of the tropical atmosphere, which leads to storm intensification.

Likewise, Cazenave 2014 had published according to altimetry data, sea level had decelerated from 3.5 mm / yr in the 1990s to 2.5 mm / yr during 2003 - 2011, and that deceleration could be explained by increased terrestrial water storage, and the pause in ocean warming reported by Argo data.

For instance, if global warming were to increase the volume of water in the oceans by causing glaciers or other ice bodies to melt, this would cause the weight of water in the oceans to increase.
