Climate Disruption and the Arctic Conveyor

I've seen more battalions of climate deniers lately than I care to even acknowledge. They engage in a game of dangerous anti-intellectualism and prefer to dwell in a place of self-enforced ignorance, where they receive as well as cultivate ongoing support for their fallacies.

This piece isn't to waste time on them, or their highly funded interest in climate denial that special interests funnel a steady flow of money into.

A great deal of intelligence can be invested in ignorance. ~Saul Bellow

Let them be ignorant, and reduced to the blather of background noise. This piece is simply a short inquiry for those who dwell in reality, surrounded by facts and thoughtful pursuits.

Here's the observation (in the form of an excerpt) and the question -- from here:


According to NASA (circa May 2004), there's a potential sometime over the next few decades for melting sea ice to trigger colder weather in Europe and North America.  This isn't the first time we've heard about the effect -- our own Darksyde (Science Friday: Mystery of the Icebox Killer, Fri Sep 09, 2005 at 07:45:05 AM EST) wrote about the possibility a year later, and we've seen a few references to many unexpected changes -- increases -- in the rate of Arctic ice melt not only in 2005 but also in 2007, 2008, 2009 (and here) and 2010 (and here.

So, what's the likelihood now of any effect on the ocean conveyor?

Granted, the past impacts happened when a massive flood of cold fresh water rushed into it -- this time, it's not such an all-at-once scenario.  But -- will the increase impact the conveyor?  Destabilize or shift it?  Alter it's speed, course or charming sense of humor?
