As for cold northern winters, Specific Heat taken in by the melting ice that is drifting South would have an impact. Anyone checked recently the distribution of icebergs in terms of their Southern and Northern drift? Not to mention the loss of ice from both poles.

Yes! That's why the Labrador coast is cold and (Gulf-stream warmed Europe) is not so.

Big chunks of ice are breaking off glaciers - http://www.universetoday.com/70785/view-from-space-huge-piece-of-glacier-breaks-off-greenland/

While thousands of icebergs detach from Greenland’s glaciers every year, the last time one this large formed was in 1962. The flow of sea water beneath Greenland’s glaciers is a main cause of ice detaching from them.

An increased flow of icebergs has been running down the US east coast since the time of the Titanic.

Using a novel technique that reveals regional changes in the weight of the massive ice sheet across the entire continent, scientists at NASA's Goddard Space Flight Center, Greenbelt, Md., report that Greenland's low coastal regions lost 155 gigatons (41 cubic miles) of ice per year between 2003 and 2005 from excess melting and icebergs, while the high-elevation interior gained 54 gigatons (14 cubic miles) annually from excess snowfall. - http://www.nasa.gov/vision/earth/lookingatearth/greenland_slide.html

How long do you think it will take deniers to latch on to the extra 41 gigatons of snow? (Bear in mind that climate change simulations predict increased precipitation in high latitudes as a consequence of warming.)

The volume of the ice-cap at the south pole is also being monitored by satellite 3D radar mapping, which can "see" the ice surface and "see" through it to the rock below it to measure its volume. In considering the South Polar Icecap we should recognise that substantial parts of the "continent" of Antarctica, though ice-covered, are below sea-level.
