Thanks Thermostat! very good link. I had sort of figure it out by myself that this record melting season in the Artic, with posiive SST anomalys nearby poles, could bring a warmer and higher precipitation rates to some areas of NH. This could trigger a long with large white-covered areas in this winter-spring NH, increasing albedo... this is the sort of things we don´t really understand well how they happen, but butterfly effects are always there... karlox, Since you are interested in the implications of the Arctic Sea Ice melt on weather patterns let me suggest that besides the immediate effects presently being observed in regions adjacent to anamolously warm arctic water, that you look at the predicted effects of the increasing open water in the Arctic Sea on the behaviour of the Northern Hemisphere Jet Stream. The melting of the Arctic Sea Ice appears to be weakening the Jet Stream; increasing the likelyhood of cold arctic air descending into North America and Europe in winter and also increasing the frequency of 'blocking patterns' such as the recent events that produced the Russian heat wave of 2010 and the American drought of 2012. (Interestingly, Superstorm Sandy was also enabled by such a 'blocking event'.)

Thermostat: Dr. Jeff Masters disagrees with what you typed above 100%. Where do you get his stuff? ?

sigurdur,
Could you link a few relevant publications by Dr. Masters regarding geophysics and the Arctic Sea Ice? I did a quick search and did not find anything.

Go to accuweather.

I went to accuweather but was unable to find anything of scientific substance. I take it Jeff Masters is what they call 'a pundit'. Fair enough.

The jet is suppose to be moving north.....when in fact it is moving south.
Another epic fail.

sigurdur, Frankly, so what? This blog post was made like 4 years ago.

sigurdur,
fyi, anybody can make a blog post. Again, so what?
This link to a 2008 blog post is a true, who cares?
Substance in science is established over time, and requires a much more meticulous process than what you have shown from the pundit Masters.

Meanwhile please look at latest Unisys SST anomaly chart... polar waters -both- looks colder than average, it also looks that a a La Niña is building up west Pacific Coast of South America; colder than average building up round Florida and Gulf and that hotspot East of Labrador Peninsula than makes me wonder where is the cold Labrador polar ocean current... and overall it looks colder oceans than average... think that jet streams are shifting nortwards (equatorial) and southerly for NH polar jet streams... wonder how this will affect ice extension and volume recovery months ahead... Would like to know if I am reading right the signs... Thanks in advance weather.unisys.com/surface/sst_anom.gif

karlox: You most certainly are reading this correctly. We are entering a period of somewhat rapid cooling. What surprises me is how fast the oceans are shedding heat.
I was trying to find some current data in regards to H2O levels in the troposphere. No luck yet.
IF H2O has dropped, that would explain the rapid decline in temperatures. H2O is still by far the largest heat retention greenhouse gas. The bands of absorbtion overlap CO2, and that is why CO2 is a minor item in the large picture.

I´ve got the feeling that a lot of more humid warmer air lows developping from Mexican Gulf and east coast of US is bringing a lot of humidity to some parts of NH, these lows -of which Sandy is the extreme- seems to draw a lot of cold air west into the US, then whenever in higher latitudes after ascending northeastwards they enter in the polar area and go to Europe, hitting mostly western part of the continent: UK, France... but I look to meteo sat images daily and NH looks very cloudy and unsettled... as it should be probably, but got the feeling it is in general wetter -excep for central US?- though I am not sure you meant that by H2O content in troposphere...
