Scientists can measure how much energy greenhouse gases now add (roughly three watts per square meter), but what eludes precise definition is how much other factors — the response of clouds to warming, the cooling role of aerosols, the heat and gas absorbed by oceans, human transformation of the landscape, even the natural variability of solar strength — diminish or strengthen that effect.

The ocean will keep absorbing the forcing energy and warming, we don't need sunspots anymore to warm.

Does the reduced albedo of the ocean mean that more energy is absorbed instead of reflected?

About half the solar energy reaching Earth is absorbed by the ocean and land, where it is temporarily stored near the surface.

Of the energy absorbed by the ocean, most is released locally to the atmosphere, mostly by evaporation and infrared radiation...

As the reflective ice disappears, it exposes the dark ocean, which more readily absorbs solar energy, further warming the region.

The key points of the paper are that: i) model simulations with 20th century forcings are able to match the surface air temperature record, ii) they also match the measured changes of ocean heat content over the last decade, iii) the implied planetary imbalance (the amount of excess energy the Earth is currently absorbing) which is roughly equal to the ocean heat uptake, is significant and growing, and iv) this implies both that there is significant heating «in the pipeline», and that there is an important lag in the climate's full response to changes in the forcing.

How can it get colder unless energy is being reflected back into space before it is absorbed / released by the earth as heat or the energy is being used to warm the oceans to a greater depth.

An example of a positive feedback is Arctic sea ice melting, which exposes the ocean, which absorbs far more energy than the snow and ice did, causing the ocean to heat (or the air to cool?).

It has something to do with the amount of energy which is absorbed in the tropics and via evaporation, ocean and air flows gets into the high latitudes.

As Arctic sea - ice shrinks, energy from the sun that would have been reflected away by sea - ice is instead absorbed by the ocean.

Globally, the Ozzies have pointed out that the oceans have been busy absorbing almost all of the heat energy (90 %) The atmosphere and the land, including ice, store the other 10 %.

Much of the higher energy ocean emissions (ignoring conduction because it is lunch money and ocean surface emission intensity is maybe 110 % of TSI) is absorbed by IR resonating molecules in the atmosphere.

As reflective ice melts, the ocean surface may absorb more solar energy, raising ocean temperatures and starting a feedback loop the melts the remaining ice faster.

I think that they will find that with a long enough path length, atmospheric water vapor tends to regulate the energy absorbed at and around the ocean thermocline layer at about 100 meters.

This occurs because as warming causes sea ice near the poles to melt, energy from the sun that would have been reflected away by the ice is instead absorbed by the ocean.

Ocean and land surfaces warm at different rates, and land covered by vegetation absorbs and reflects solar energy differently than do deserts or ice - caps.

bozzza - The differences in the Arctic are perhaps 1/4 the ocean thermal mass as global ocean averages, small overall size (the smallest ocean), being almost surrounded by land (which warms faster), more limited liquid interchanges due to bottlenecking than the Antarctic, and very importantly considerable susceptibility to positive albedo feedbacks; as less summer ice is present given current trends, solar energy absorbed by the Arctic ocean goes up very rapidly.

A new paper by Trenberth et al. (2014) notes that the amount of heat accumulating in the global climate (most of which is absorbed by the oceans) is generally consistent with the observed global energy imbalance.

It is estimated that, in an annual basis, the amount solar energy absorbed by the oceans is equivalent to at least 4000 times the amount presently consumed by humans.

to clean energy; yes to dense, beautiful, and affordable communities; yes to safer streets for everyone from children to the elderly; yes to a walkable, bikable, transit - rich transportation system; yes to electric vehicles, internet - speed ride sharing, and the smart grid; yes to wind, solar, and ultra-efficiency; yes to innovation and science and solutions we haven't even imagined yet; yes to restored, carbon - absorbing grasslands, to oceans no longer endangered by acidification, and to towering Northwest forests regrown to once again capture vast quantities of carbon.

That is to say, some energy may appear positive (by adding to the temperature signal) and others energy may appear negative (by, for example, being absorbed by the ocean deeps).

The main feature of this regime is that during this time, the ocean radiates about the amount of the energy that it absorbed during all of the previously described regimes.

Since 1955, more than 90 percent of the energy trapped by the atmosphere as a result of increased greenhouse gasses has been absorbed into the oceans.

In fact there is a gravitationally induced temperature gradient (aka lapse rate) in any planetary troposphere, and thermal energy absorbed from solar radiation in the upper troposphere can flow up that sloping thermal profile restoring thermodynamic equilibrium as it does so, and even entering the oceans.

This is largely because land tends to reflect the Sun's energy back to space, while the oceans absorb the Sun's energy.

With less sea ice, the refrigerator door is left open - darker open water is exposed, which readily absorbs the Sun's energy in summer, heating the ocean and leading to even more melt.

Oceans absorb solar energy at ~ 95 % or so because of their low albedo.

A new paper by Trenberth et al. (2014) notes that the amount of heat accumulating in the global climate (most of which is absorbed by the oceans) is generally consistent with the observed global energy imbalance (see the previous post for further details).

For as much as atmospheric temperatures are rising, the amount of energy being absorbed by the planet is even more striking when one looks into the deep oceans and the change in the global heat content (Figure 4).

Yes, and the thermal energy absorbed in the top of the ocean will also disperse to greater depths by diffusion, convection and ocean currents.

Still, they indicate that some areas of the ocean are heating up especially fast, such as the Arctic Ocean — which this year had its lowest winter ice year on record — and is absorbing much more solar energy as melting ice cover exposes new dark surfocean are heating up especially fast, such as the Arctic Ocean — which this year had its lowest winter ice year on record — and is absorbing much more solar energy as melting ice cover exposes new dark surfOcean — which this year had its lowest winter ice year on record — and is absorbing much more solar energy as melting ice cover exposes new dark surfaces.

New thermal energy being absorbed can be thought of like various showers of rain falling on an ocean.

This reflects the continued increase of energy in the oceans, which absorb over 90 % of the heat trapped in the atmosphere by greenhouse gases, the report says.
