However, even a smaller figure (I had calculated about 0.17 W / m ^ 2 based on your inflated figure for total planetary albedo, but you can check it out) is still significant when compared with the total flux imbalance, which I think is a more informative comparison than an arbitrarily selected change in cloud cover, because it compares the sea ice reduction with the effects of all climate variations that have been operating in recent years..

If you consider that the Earth is also about 2 / 3rds cloud covered and any CO2 or other GHG absorption would not matter because the clouds would be absorbing the energy anyway, over 90 % of the GHE is from water vapor and / or clouds and less than 10 % is from CO2 and other GHGs.

From the figures I took an average value of 0.45 — but, hey, if you prefer to assume 0.35, that's OK, because it will not change the conclusion that the observed Arctic sea ice melt has not appreciably changed our planet's total albedo, and that a very small change in cloud cover would have a far greater effect.

That's because of feedbacks in the climate system, such as Arctic ice melt and changes to cloud cover, as well as the potential melting of ice sheets.

With the Earth known as the «water planet» because of over 70 % of the globe covered by deep oceans, warmer temps directly result in more evaporation of the ocean water into the air - clouds.

It changes because of greenhouse gases, cloud and ice cover changes, land clearing, volcanoes, dust and soot in the atmosphere — all of the physical changes that result in a change in the radiative flux leaving the planet either as IR (heat) emissions or as reflected sunlight.

At this point, the GCMs increase clouds because clouds also produce a GHE, but the GCMs don't use the increased water vapor and clouds to increase cloud cover, thereby increasing cloud albedo, the mitigating reaction in nature.

because increased Tmin can also be due to changing cloud cover.

The exact amount of this temperature increase, however, remains uncertain because of unpredictable changes in other atmospheric components, especially cloud cover.

In the first scenario, any further drops in temperature would not be offset by any further reduction in cloud cover, because no such reduction would be possible, and in the second scenario, any further increases in temperature would not be offset by any increase in cloud cover, because the cover is already full.

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.

As the CO2 and CH4 (methane) level goes up, H2O vapour in the atmosphere falls which — because H2O is 30 times more important than CO2 as a «greenhouse gas» offsets the effect of CO2 on temperature, while cloud cover and albedo increases because warmed moist air rises to form clouds, further cooling the world.

Basically, Dr Ferenc Miskolczi's life as a NASA climate research scientist was made hell because he discovered that the extra water vapour being evaporated is not having a positive - feedback (increasing the CO2 warming effect by absorbing more infrared from the sun), instead it is going into increased cloud cover, which reflects incoming sunlight back to space.
