This is what I get out of it: the Arctic - ice - albedo situation is more complicated than earlier thought (due to clouds, sun - filled summers, dark winters, etc), but NET EFFECT, the ice loss and all these other related factors (some negative feedbacks) act as a positive feedback and enhance global warming.
Similar negative effects occur with worsening air pollution — higher levels of ground - level ozone smog and other pollutants that increase with warmer temperatures have been directly linked with increased rates of respiratory and cardiovascular disease — food production and safety — warmer temperatures and varying rainfall patterns mess up staple crop yields and aid the migration and breeding of pests that can devastate crops — flooding — as rising sea levels make coastal areas and densely - populated river deltas more susceptible to storm surges and flooding that result from severe weather — and wildfires, which can be ancillary to increased heat waves and are also responsible for poor air quality (not to mention burning people's homes and crops).
# 92 Spencer el al 2007 paper doesn't really support the precise mechanism proposed by Lindzen for Iris effect, but more simply observes a strong TOA negative correction associated with warming events at 20 ° S - 20 ° N (that is: in the 2000 - 2005 period of observation, the most significative warming episodes of the surface + low troposphere — 40 days or more — leads to a negative SW+LW cloud forcing at the top of the atmosphere).
Spencer + Braswell have shown that over the tropics on a shorter - term basis, the net overall feedback from clouds with warming is negative; this is largely due to an increase in reflection of incoming radiation by increased clouds with a smaller effect from the reduction of energy trapping high altitude clouds, which slow down outgoing radiation by absorbing and re-radiating energy.

@David: You write: «If the beneficial aspect of CO2 increases in a lineal manner and the warming effect of CO2 decreases logarithmically, then does it not makes sense that at some point CO2 itself becomes a negative feedback?»
While the global warmmongers continue to wring their hands over rising temperatures hurting yields (the Corn Belt growing season has indeed warmed slightly since 1960), improved varieties and the «global greening» benefits of more atmospheric CO2 have more than offset any negative weather effects — if those even exist.
Before it is safe to attribute a global warming or a global cooling effect to any other factor (CO2 in particular) it is necessary to disentangle the simultaneous overlapping positive and negative effects of solar variation, PDO / ENSO and the other oceanic cycles.
Its warming effect, however, is simultaneously amplified and dampened by positive and negative feedbacks such as increased water vapor (the most powerful greenhouse gas), reduced albedo, which is a measure of Earth's reflectivity, changes in cloud characteristics, and CO2 exchanges with the ocean and terrestrial ecosystems.
Amongst other things the above link (2) shows how the negative PDO from 1961 to 1975 cancelled out the warming effects of solar cycles 18 and 19 and led to a cooling trend during those years despite the relatively high TSI levels.

But the utter incoherence of views presented by deniers gives the game away even so (it's cooling, it's warming but the sun is responsible, it's warming but some unknown natural cycle is responsible, the «greenhouse» effect violates the laws of thermodynamics, but somehow the energy radiated back to the surface by the atmosphere simply vanishes, there is a greenhouse effect but negative feed - backs make it negligible, & c ad nauseam).
(While the data did suggest strong positive water vapor feedback, which enhances warming, that was far exceeded by the cooling effect of negative feedback from cloud changes.)»
[37] This hypothesis suggests a negative feedback which would counter the effects of CO2 warming by lowering the climate sensitivity.
The prominent upward trend in the GM precipitation occurring in the last century and the notable strengthening of the global monsoon in the last 30 yr (1961 — 90) appear unprecedented and are due possibly in part to the increase of atmospheric carbon dioxide concentration, though the authors» simulations of the effects from recent warming may be overestimated without considering the negative feedbacks from aerosols.

To point out just a couple of things: — oceans warming slower (or cooling slower) than lands on long - time trends is absolutely normal, because water is more difficult both to warm or to cool (I mean, we require both a bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase change inside oceans, so no latent heat) or oceans begin to release heat but in the same time they have to cool (because they are losing heat); so, I don't feel strange that in last years land temperatures for some series (NCDC and GISS) can be heating up while oceans are slightly cooling, but I feel strange that they are heating up so much to reverse global trend from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this effect, I would not exclude it from having a small part in temperature trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands» temperatures are often measured in a not so precise way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters» temperatures trend; — metropolis and larger cities temperature trends actually show an increase in UHI effect, but I think the sites are few, and the covered area is very small worldwide, so the global effect is very poor (but it still can be sensible for regional effects); but I would not run out a small warming trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than air during day, and how much it can slow night - time cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a full view of UHI effect (still remembering that it has a small global effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).
Observed data and many studies indicate that a warming climate has a negative effect to crop production, generally reduce yields of staple cereals such as wheat, rice and maize, which, however, differs between regions and latitudes.
BTW: There is no physical evidence that the assumption of a net positive feedback is correct, and much physical evidence to suggest that the real world feedbacks are net negative and will reduce the proposed direct warming effect of CO2 towards (closer too) 0.
None of the Annan / Hargreaves priors go below zero, and while this may be physically realistic it does not allow for the fact that the observational data generate negative sensitivities, mostly because of ocean cycle warming and cooling effects that the radiative forcing estimates do not take into account.
Meanwhile, the logarithmic effect of CO2 is excellent «concession» to make in the rhetorical sense, since it concedes the obvious state of our knowledge about the effects of CO2, while at the same time providing us with the solid argument that even if we double atmospheric CO2 levels from 400ppm to 800 ppm over the next 100 years the largest amount of warming possible — assuming all else remains the same and Gaia has no homeostasis negative feedback systems which tend to moderate any runaway trends — is 1.2 c.
2 °C of warming would have very negative effects, which is why it is important to swiftly work towards the Paris goal of the 1.5 °C limit.
If the negative effects of climate change, the rising air temperatures, the changing precipitation, the prevalence of extreme weather events, and the rising sea levels, become too disruptive or costly, we have the option to deploy certain climate altering technologies to remove greenhouse gases directly from the air or reflect sunlight back out of the atmosphere before it warms the earth.
