Couldn't these guys (How many are there total?) be responsible for much of the article ice sheet destruction over the past 50 years?

If they keep destroying the ice "sheet" then how can it ever grow deep and strong.

I wonder if this is a bigger reason than too many cows farting somewhere in Iowa.

It's all a political agenda, and pseudo-religion by ignorant people that do not understand that everything we know about "Global Warming" is in about 25 computer models ... and people pick and choose the computer models that will generate the most grant money, and discard the others.

The Earth's climate is ALWAYS changing.

At one time the ENTIRE planet was covered in about two miles of ice.

(See the PBS documentary "Australia - the First 4 Billion Years")

The political agenda is all about MONEY!

The buying and selling, and brokerage fees for buying and selling "Carbon Credits" ...

Just another opinion here, but I can't see any connection. Breaking the ice with one of these nuclear powered ice-breakers touches such a minute fraction of the ice and does virtually nothing to the temperature of the water, or the ice.

Also, nuclear power is about the most efficient type of power for producing green energy with no additional greenhouse gases added to the atmosphere. Of course, due to a couple near disasters and real disasters (3 Mile Island, Chernobyl, Fukushima) the "Green" crowd will usually fight against this form of "green" energy."

@JW Insider What about all the "heat" that the ship produces to make such energy? it is dispersed up there in the arctic.

so in addition to the ice sheets being cut up into smaller sheets allowing for a much larger solar energy "edge" surface area by the hundreds of miles on each side of the ship....

The nuclear power (heat) of the ship itself radiates / elevates the overall heat up there...

And I think I read that Russia has a dozen or so of these things? The USA one or two? And what about all the other countries?

Maybe they are tearing it all to shreds? 

Maybe that is why it is disappearing?

I'm guessing that this person is on the right track:

Meier decided to crunch some numbers and find out. While his numbers are an estimate, he said, they provide a helpful comparison of just how much icebreakers might contribute to summer ice loss. Meier said, “In late June, when the sun’s energy is strongest, the total sea ice extent is around 10 million square kilometers or 3.9 million square miles. An icebreaker cruising through the ice for 1,000 kilometers (620 miles) and leaving an ice-free wake of 10 meters (33 feet) would open an area of water 10 square kilometers (3.9 square miles) over the entire cruise. In contrast, the Arctic sea ice cover decreases by an average of over 9 million square kilometers or 3.5 million square miles each year during its melt season—an area larger than the contiguous United States.  In total, researchers estimate that the number of icebreakers traversing the Arctic at any given time is usually less than three. So, Meier said, “The actual contribution is miniscule—only one part in a million of the total ice cover.”

That is why you don't bleed to death from a mosquito bite.

... and you are too heavy to carry back to the breeding pond.

.... and when you look at an ocean covered in ice ... that's ONLY the top.

... there is a lot more underneath that.

... same thing.

When I was a boy, I got shot in the face several times with BB gun bbs, in BB gun battles.

You just push on one side and they pop right out.  Leaves a small pocket for about a day, then closes right up.

...same thing.

It takes  any specific Icebreaker Ship the same amount of energy to push through and break up ice, whether you are using oil as fuel, coal as fuel, uranium as fuel, or 400 million hamsters on a wheel, turning the Icebreaker's engines.

To do work, energy needs to flow from a greater concentration to a dump, or it will not move anything.  The amount of waste energy in an Internal combustion Engine of any type is about 60% ... even in your car.  Turbines, which many ships have to have heat dumps, nuclear reactors ... and even hamsters sweat like crazy to get rid of heat.
