Your statement that «Thus it is natural to look
at the real world and see whether there is evidence that it behaves in the same way (and it appears to, since model hindcasts of past changes match observations very well)» seems to indicate that you think there will be no changes in

cloud responses thereto or other atmospheric circulation.
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

at the surface and changes in observed
ocean heat content.

In this lecture, we looked for the

Recently she has curated Kamarados

He notes that the sat photos show that
cloud cover remains low and that the ice is very mobile
at a time when the pack should be most firm (not really a surprise since
ocean temps are much more important than air temps, and apparently it's the
ocean temps that have been the largest factor in the recent sharp sea ice reduction).
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).
sheesh 2 DEGREES just look
at the s ** t we are getting
at 0.8 degrees Its like goodbye coral reefs, goodbye amazon rainforest, goodbye himalayan glaciers that provide water to 40 % worlds population (lot of poeple in china), goodbye east india monsoon rains needed to grow crops, hello more droughts, hello more forest fires, hello more heat waves, hello more stronger huricanes / typhones / cyclones, hello more floods (because warmer
oceans have even more water evaporated from them turned into
clouds and blown over land so even more rain pours down
at once), hello more jellyfish (they thrive in acidified
oceans because of CO2 absorbtion).
And just as increased algal productivity
at sea increases the emission of sulfur gases to the atmosphere, ultimately leading to more and brighter
clouds over the world's
oceans, so too do CO2 - induced increases in terrestrial plant productivity lead to enhanced emissions of various sulfur gases over land, where they likewise ultimately cool the planet.
Long waves (infrared) light from the sun, GHGs,
clouds, are trapped
at the surface of the
oceans, directly leading to increased «skin» temperature, more water vapor (a very effective GHG), faster convection (with more loss of heat to space in the tropics),... How each of them converts to real regional / global temperature increases / decreases is another point of discussion...
Your statement that «Thus it is natural to look

Kasting had one very primitive go
at a radiative - convective study of the effect of
clouds on runaway greenhouse, which suggested that
clouds might prevent the whole
ocean from going aloft.
1.3 W / m2 TOA) in direct sunlight may give such a large variation
at the
ocean's surface is probably a question of modulation of
cloud cover.
At some point you have to tell them they need new squid ink because the
ocean of plausibility has already been saturated with their old formula and doesn't have the water -
clouding power it used to have.
As for the Sun, well, like AnnaV I consider that the 2 by far most important factors in climate evolution is the cloudiness because it governs albedo and the large scale
oceans» behaviour because that's where the energy is Again you are so angry
at the AGW crowd, that you miss the whole point: the all - important
clouds and albedo vary together, but do not vary with the solar cycle, as far as our observations go, e.g. http://www.leif.org/research/cloud-cover.png and http://www.leif.org/research/albedo.png
Your 30 °C could be relevant if most of the global
ocean was
at 30 °C but it isn't, and in the ex-tropics
cloud cover decreases as temperature rises during summer.
Notably, by studying the
clouds over a limited region of the atmosphere over the eastern Pacific
Ocean, as well as over nearby land masses, the team
at the university's International Pacific Research Centre have declared themselves firmly in the latter camp, warning that, as temperatures continue to creep steadily upwards over the next 100 years,
cloud cover will become thinner and more - sparse, thereby serving to exacerbate the problem.
ii) The
oceans appear to vary in the rate
at which they release solar energy back to the air which affects atmospheric composition via humidity,
clouds and global albedo.
Most interesting is that the about monthly variations correlate with the lunar phases (peak on full moon) The Helsinki Background measurements 1935 The first background measurements in history; sampling data in vertical profile every 50 - 100m up to 1,5 km; 364 ppm underthe

Disputes within climate science concern the nature and magnitude of feedback processes involving
clouds and water vapor, uncertainties about the rate
at which the
oceans take up heat and carbon dioxide, the effects of air pollution, and the nature and importance of climate change effects such as rising sea level, increasing acidity of the
ocean, and the incidence of weather hazards such as floods, droughts, storms, and heat waves.
The system has a large number of interacting parts —
cloud, ice, biology, dust,
ocean and atmospheric circulation — that together result in climate variation
at all scales.
It shows an
ocean heat peak in the 1990's — that follows changes in
cloud radiative forcing
at toa.
Whatever wide - ranging coherence one finds
at multi-decadal frequencies is more likely the result of global - scale variations in
cloud - regulated thermalization of solar irradiance and the lagged advection of heat from the tropics by winds and
ocean currents.
There are changes in
ocean and atmospheric circulation — and
cloud —
at multidecadal scales.
Although substantial interdecadal variability is present in the time series, long - term decreases in upper - level
cloud cover occur over land and
ocean at low and middle latitudes in both hemispheres.
As Roy Spencer points out, it doesn't take much of a change in
cloud cover to account for global warming due to increased insolation *
at the
ocean surface *.
Over the
ocean this includes: sea surface slope and surface current, significant wave height, wind speed and sea level from radar altimetry
at about 10 km resolution: sea surface temperature under
cloud free conditions from the infrared radiometer
at about 300 m resolution; chlorophyll a and phytoplankton from the imaging spectrometer under
cloud free conditions
at about 300 m resolution.
Of course that relegates CO2 to a bit part
at best, since it is
clouds / water vapor that regulate how much energy enter the
oceans and how much is deflected.
I was thinking along those lines, inland, away from the
ocean there would be less
cloud and more radiation to space
at night, lowering Tmin and lowering the average.
I say my conclusion was «not unreasonable» because Dr. Scafetta, in a posting
at WattsUpWithThat today, has also concluded that, once the natural 60 - year cycles of the great
ocean oscillations are accounted for (and it may be these cycles that express themselves in changes in
cloud cover such as that which Dr. Pinker had identified), the anthropogenic component in global warming is considerably less than the IPCC imagines.
Could it be that the
ocean has maintained surface temperatures
at a high level these last seven years because it is dissipating heat it gained while the sun was very active and
cloud albedo was reduced in the later C20th?
Several factors play a role when a hurricane gains more power rapidly, including the temperature of the surface of the
ocean, humidity, characteristics of the
clouds, the heat content in the
ocean, and the direction of the wind
at the surface compared to miles above.
Spencer / Braswell and Lindzen / Choi look
at the relationship between changes in
ocean heat,
cloud cover (directly affecting the amount of heat lost to space), and global surface temperature over recent decades.
