The really good thing about the climate «debate» is that the causations proposed by both sides — CO2 or cloud cover — will reveal themselves in the next few years.

Since the result comes from measurements of absorption at infrared wavelengths, the results are strictly valid only for relatively cloud - free locations (cloud cover fraction over a 300 km region less than about 60 %).

It looks as if the curve has been readjusted at some stage, but it is then a bit strange that the curve representing the global lower cloud cover doesn't seem to have been re-scaled: the difference between maximum and minimum is about 3 % in both figures (it's annoying that the vertical axis for the cloud cover are given in different units in Fig. 2 & 3).

About humidity, rainfall, and cloud cover much less is known.

Our understanding of these phenomena and our ability to model them are primitive,...» While there are doubts about the link between cosmic rays and cloud cover, there is an observed significant link between (low) cloud cover and solar radiation within the last two sun cycles.

As I understand it, the basic theory is that incoming charged particles provide additional cloud condensation nucleii (like the cloud chambers used as detectors in early subatomic physics), that the rate of incoming particles is modulated by the magnetic fields of the sun and earth, and that therefore the amount of cloud cover varies with the particle flux, which in turn drives climate, so we can stop worrying about CO2.

I look at the basics of radiative physics and ask follow - up questions about details, including details entailed in non-radiative physics My favorite questions to date: (1) if, as Chris Colose wrote in the earlier thread, Willis Eschenbach's graphical analysis of cloud cover and temperature is basically correct, does that not make a reasonable case that cloud cover increases can be expected to prevent future warming from future CO2 increases?

I'm wondering about Transantarctic mountains, altitude, humidity, dehumidification, increased cloud cover and the creation of more Antarctic ice through this process.

Considering the heat capacity of the oceans is about 1,100 times greater than the air, would not even a modest change in cloud cover affect the radiative balance with far greater magnitude than a parts - per - million change in an atmospheric gas constituent?

Gu's research indicates that the maximum uptake of carbon dioxide by plant ecosystems occurs when cloud cover is about 50 percent.

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..

Again, I do not see much to get excited about here, particularly when considering that the albedo increase from a 1 % increase in cloud cover would more than offset this decrease.

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.

Clouds are one of the big unknowns about global warming as they can have a range of effects, warmer temperatures caused by global warming will result in higher rates of evaporation and therefore will result in higher cloud cover.
