Yes, dark dust effects earth's albedo. It's most noticeable in late summer, after melting. In winter, when it's snowing all the time, it has almost no effect. As I said, it is one factor of many. But you stated in this thread that melting sea ice has no effect on earth's albedo. It is a scientific fact that open ocean absorbs more heat than snow and ice. You are so wrong that it's laughable, and you are embarrassing yourself...again.

you didn't peruse there waldo...this is in winter dude
The world's highest glacier, Khumbu, was turning visibly darker as particles of fine dust, blown by fierce winds, settled on the bright, fresh snow. "One-week-old snow was turning black and brown before my eyes," she said. The problem was even worse on the nearby Ngozumpa glacier,
Cryoconite is also important because it bonds the dust to the glacier's surface, darkening the glacier. Darker glaciers absorb more energy from the sun and melt faster,
Source apportionment suggests that more than 94% of the BC (black carbon) is emitted from mostly regional anthropogenic sources while the remaining contribution comes from natural biomass burning. Even though the annual deposition flux of mineral dust can be up to 20 times higher than that of BC, we find that anthropogenic BC causes the majority (60% on average) of snow darkening. This leads to summer snowmelt rate increases of up to 6.3% (7 cm a−1) on glaciers in three different mountain environments in Kyrgyzstan, based on albedo reduction and snowmelt models.
OK, one more time: I did not say that the dust doesn't effect albedo. I said that it certainly does, but that there are many other factors. You are the one who claimed that the melting ice does not effect albedo, which is ridiculous, and demonstrably false. Open water absorbs far more heat than snow and ice.

This is you claiming that shrinking ice extent does not effect albedo, and claiming that all scientists know this. You are embarrassing yourself.
"… as the cold winter air swoops over the arctic circle where there used to be ice. It will load up the clouds and dump salty snow on the lower 48 like never before …":
Umm, nope, it doesn't work that way.
As the water evaporates, the salt is left behind, and the salt free water vapor is lifted into the atmosphere (more precisely the troposphere) potentially forming clouds. Not hugely unlike what happens in a still.
P.S.: Consider the Gulf Stream, and the prevailing winds associated therewith; if what you suggest were true, the Nordic countries would have been inundated with "salty snow" for several hundred years at the very least. Nope. Didn't/doesn't happen.

OK. Since you guys can't seem to tell the difference between science and pull it out of my butt BS here is theory 2 for Global warming and its consequences.
The polar ice cap will melt. For various reasons. But it will go away. Since ice is lighter than water the top of the earth will 'get light'. Just like the front end of a SkiDoo if you take out the coupler blocks. The earth will tilt so that the heaviest part will now be the south pole. Antarctica will be pointed at the sun all the time as it rotates around the sun. This will confuse the moon and it will go into an eliptical orbit. Instead of having equal and predictable tides the ocean will end up rising 38 feet on the western coast of Africa. That water has to come from somewhere and it will come from the US coast of South Carolina. Instead of being flooded out new structures will be built where the ocean once was. In addition to North Carolina and South Carolina there will be an East Carolina too. It will be a tropical paradise. There will be pink flamingos and sushi bars. They will grow pecan trees and raise albino goats. However it will get colder in the UP and Minnesota since we will be farther away from the sun. So the snowmobile industry will boom once more. Montgomery Ward will even get back into the sled business.
Tear that one apart doubters!!!! I have done extensive research to support my new theory.

So when all that ice (lighter than water) melts and is replaced by water (heavier than ice), the top of the earth will 'get light'?
Cuz of all that 'heavier' water replacing the 'lighter' ice, yes?
Naw, it's all about (click →) Milankovich Cycles.
See also: (click →) "Milankovich Cycles and glaciation".
And it's looking like the Milankovitch cycles effect volcanic activity, amplifying the effects beyond what the variation in solar energy does. http://www.people.fas.harvard.edu/~phuybers/Doc/Kutterolf_Geology2012.pdf

Holy cow....I haven't visited here for awhile. I never realized the number of scientists that ride snowmobiles and hang out on this website. I never put the two together. At least I can say I learned something new today.
