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?

Don't know if you are aware of it but the old Cod War has now been resurrected by the Mackerel War - the result of a significant change in the migration pattern of mackerel. The new pattern takes them much further north into Iceland's waters - which is pissing of the EU countries to the south. Annual surveys show the stock has exploded around the island.

Iceland for some time has been witnessing climate change - dating back to the 1970's when fishermen first started noting a consistent change in the migration patterns of local birds (most notably the Puffin). If you talk climate change to an old fisherman in Iceland (70-80 y/o), the first thing they want to know is where you've been hiding for the last 40 years.

Americans were given a choice: A. put on a sweater and turn down the thermostat or B. have a party and put it on the tab.

They chose B - Ronald Reagan.

I am not optimistic about the future. I think it's too late. At best we might be able to mitigate things a bit, but it's probably getting way past time now to shift to how to cope. Localized economies, localized power sources (wind should be a biggie), localized agriculture and water, shifting away from desert communities, etc.

But, as far as I can tell, the party isn't over yet.

 

shifting in ways that may not be noticed on a wide scale until the additional implications and impacts become obvious. Once that happens, I suspect there will be updated assessments on the depth and breadth of the climate disruption, but not necessarily enough information about how to resolve it...or even how to approach it.

Above all other things, I want to find some way to hold those who delay / deny and intentionally derail any attempts to deal with real-world events like this responsible for their actions.

Historically and permanently.

There has to be some way to promise that in a way that will hopefully give ~some~ of them pause.

Dear Friends , I am sure that Nature is trying to heal itself, with or without our permission , so let us get ready for the new coming ICE AGE witch my destroy or effect badly on human civilization.
