Regardless, I would posit the worsening winter ice formation is as expected given the poles suffer first and winters warm faster than summers, BUT that this is happening within two years of the EN peak, which was my time line in 2015, one wonders if the combination of warm EN - heated Pacific waters (oceans move slowly) and warm air are a trailing edge of the EN effect OR this is signallibg a phase change driven by that EN, or is just an extreme winter event.

(1) Of the other anthropogenic factors, some have a warming effect (other greenhouse gases such as methane) while others have a cooling effect (air pollution).

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

So, if you have two identical glass greenhouses with thermally isolated mercury thermometers at equilibrium in the sunlight [One with Air at Press =P, and the 2nd w / CO2 at Press =P], and you close the blinds — you will see the thermometer in the CO2 greenhouse retain its temperature longer — not because of any «global warming» type effect, but simply because Air conducts heat to the walls of the greenhouse better than Air does.

The net effect of these anomalous winds is a cooling in the 2012 global average surface air temperature of 0.1 — 0.2 °C, which can account for much of the hiatus in surface warming observed since 2001.

Just two remarks: you keep on saying that the effect of increased cloudiness «should be warming», whereas the data shown in the article clearly show the opposite (more clouds cause lower surface level air temperatures).

Re # 4, Hansen et al say «We find evidence of local human effects («urban warming») even in suburban and small - town surface air temperature records, but the effect is modest in magnitude and conceivably could be an artifact of inhomogeneities in the station records.

It also helps explain the initial cooling after the Industrial Revolution began (the smoke effect overwhelmed the relatively weak warming effect back then), the increase of global temperture during WW2 (shut down of industries) and decrease after WW2 (re-industrialization) and acceleration in the 1970's after the passage of the Clean Air Act.

Re 9 wili — I know of a paper suggesting, as I recall, that enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any warming (aside from greenhouse feedbacks) and more so with a warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).
