The Vanishing Arctic Ice Cap

Monday, 31 March 2014 10:07
By Dahr Jamail, Truthout | Report

An Arctic largely devoid of ice, giant methane outbursts causing tsunamis in the North Atlantic, and global sea levels rising by several meters by mid-century sound like the stuff of science fiction.

But to a growing number of scientists studying Anthropogenic Climate Disruption (ACD/climate change), these dramatic predictions are very real possibilities in our not-so-distant future, thanks to the vanishing Arctic ice cap, which is continuing its rapid decrease in both volume and area.

Arctic sea ice researchers are predicting that sea ice will no longer last through summers in the next couple of years, and even US Navy researchers have predicted an ice-free Arctic by 2016. Whichever year the phenomenon begins, it will be the first time humans have existed on Earth without year-round sea ice in the Arctic, and scientists warn that this is when "abrupt climate change" passes the point of no return.

To read more about anthropomorphic climate disruption and how environments and communities suffer from corporate profit-seeking, click here.

"In the first year that this happens, the open Arctic Ocean state will only last for a few weeks to a month or so," Paul Beckwith, a climatology and meteorology professor at the University of Ottawa, Canada, told Truthout. "Within a year or two, the open water duration [no sea ice] will last for several months, and within a decade or so the positive feedbacks will likely clear out the Arctic Ocean basin for most of the year."

Beckwith, an engineer and physicist who is also researching abrupt climate change in both present day and in the paleo records of the deep past, warns that losing the Arctic sea ice will create a state that "will represent a very different planet, with a much higher global average temperature, as much as 5 to 6 degrees C warmer within a few decades, in which snow and ice in the northern hemisphere becomes very rare or even vanishes year round."

The UN Intergovernmental Panel on Climate Change (IPCC), the world's most authoritative voice on climate science, whose reports influence policy and planning decisions of national governments across the world, has just released its latest report. The IPCC has been accused by much of the scientific community of having a starkly conservative bias.

Scientific American has said of the IPCC: "Across two decades and thousands of pages of reports, the world's most authoritative voice on climate science has consistently understated the rate and intensity of climate change and the danger those impacts represent."

However, the recently released IPCC report is raising eyebrows: Even this conservative body is predicting dire threats for people and other species in the near future, and these risks may very well mean "abrupt or drastic changes" that could lead to unstoppable and irreversible climate shifts like the melting of both the Arctic ice cap and Greenland's glacial ice.

According to the IPCC report, the polar bear is not alone in being under threat.

"The polar bear is us," says Patricia Romero Lankao of the federally financed National Center for Atmospheric Research in Boulder, Colorado, referring to the first species to be listed as threatened by global warming due to melting sea ice.

Beckwith, who believes the planet is already in the early stages of abrupt ACD, offered grave predictions of what we might expect from losing the Arctic ice.

"As the planet transitions through this abrupt climate change, there will be wrenching turmoil and conflict for human civilizations," he explained. "As the extreme weather events ramp up this will result in a frenzy of human activity to attempt to adapt and mitigate. Essentially, this tipping point in the Arctic will inevitably result in a tipping point in human response to the problem."

"Dire" is right. Personally, I think it's already past the point of no return as things stand now. Our only hope, in my opinion, is an option that's almost too heartless to contemplate. And if I think it's the only option, I'll bet there are others, in positions of power, that think the same.

I hear ya, but when one says the earth will be so and so many degrees hotter, like everybody says, that does not mean anything tangible to me, and probably not to a lot of other people. I'm wondering if anybody translated that average earth temperature rise measure into something tangible like how many more hot days will we have over 100deg, or the temperature when plants wilt, in some major cities around the world, and how many fewer cold days under 32 degrees where snow can no longer fall will we have? i.e. some number that can tell me if I can no longer plant a garden in the summer, or no longer build a snowman in the winter. Something like that would give better sense of the issue to me, and maybe to a few other simple minded folks like me.

all those natural resources up in the arctic

and the US behind on ice breakers to get them

other countries have them

we will be insignificant if we don't grab those resources

there is an ice breaker gap between the US and China

Soon enough property values all across Florida will be right down the shitter. Flushed right out to sea.

Just imagine - all of Florida under water. So much for the mortgage industry. I'm sure the banks will be fine, they will either bet against mortgages within 100 feet elevation of sea level, or they'll beg for a bailout -

and hope they aren't the ones sitting in Lehman Brothers seat.

Honestly it's really gonna suck, but it is on the way, and it will shut these stupid libertarians up for once, so in some very practical and concrete ways,

I wonder how property owners in North Carolina are going to react once the sea level finally reduces the value of their sea side property to ZERO given the legislative efforts to bury their heads in the sand . . .

I mean, I don't know about you, but I suspect some of those property owners, most especially those who find themselves under water, will be quite upset . . .

EXXON admits it and then doubles down on making more of it!

[-] 1 points by ZenDog (13362) from South Burlington, VT 3 months ago

and this?

  • It thus remains entirely uncertain what sort of action Exxon believes climate change actually "warrants," seeing as how it's not prepared to sell a single drop less of its own oil reserves.

obviously what they see as necessary is just a little bit of volcanic perturbation . . . despite the consequences

[-] 1 points by ZenDog (13362) from South Burlington, VT 3 months ago

What a bunch of horseshit . . .

  • ExxonMobil, which has in the past pursued and funded efforts to propagate the view that climate change isn't occurring at all, has taken the unusual step of publishing an entire report affirming its existence. The aim may be to assuage shareholders about the IPCC's dire climate findings, also released this week. That synthesis of the last six years' worth of climate research found that global warming threatens to do no less than destabilize human civilization as we know it.

what really scares them is the possibility of suit settlements that absolutely dwarf anything the tobacco industry has seen.

This entire industry should be taken over by the government - but only after the conservatives nationwide have been beaten into submission or driven to such a state of despair that they don't bother to hide, they just off themselves screaming

Meanwhile, the Greenland icesheet is melting at a rate of up to 27 meters a year.

That's a lot.

There is now some evidence that it's also beginning in parts of Antarctica.

[-] 0 points by ZenDog (13362) from South Burlington, VT 3 months ago

I think it was you who posted a link to an article indicating that the Greenland Ice sheet is melting even in the north, in an area that had been presumed to be relatively stable.

[-] 0 points by shooz (17782) 3 months ago

Yep. At the moment they are re-calibrating their instruments.

Here's the link, if you've lost it.

I saw a Vice program last week were the guy that measures the ice there, found glaciers that were melting at the rate of 27 meters a year.

That's a hell of a lot melting.

[-] 0 points by ZenDog (13362) from South Burlington, VT 3 months ago

Isn't the total of Greenland melt off a lot more than that?

[-] -1 points by shooz (17782) 3 months ago

That's glacial depth, not how much has calved into the sea.

All that water runs underneath the glacier and speeds up calving.

[-] 0 points by ZenDog (13362) from South Burlington, VT 3 months ago

glacial dynamics are kinda interesting. I think it was in the science times of the nyt years ago - but I've read somewhere that the weight of a glacier itself tends to make the ice at the bottom just a bit elastic and slippery.

Add just a little melt off and a glacier can act like a freight train. It's amazing really.

[-] -1 points by shooz (17782) 3 months ago

Although you don't hear them say much about it, that's a lot of weight coming off the crust of the Earth too.

Can you say earthquakes?

[-] 0 points by ZenDog (13362) from South Burlington, VT 3 months ago

I've heard Lake Champlain is still rising from the retreat of the last glacier, which was a couple of miles thick, or so I've heard. That could very well explain the small earth quakes we get in the North East from time to time, often centered just north of the border.

[-] -1 points by shooz (17782) 3 months ago

It makes sense that as all that weight shifts, the crust will react in one way or another.

That's a science that's not well developed.

[-] 1 points by ZenDog (13362) from South Burlington, VT 3 months ago

measuring change of that nature requires time, I'm sure. We can't be talking about more than an inch a year and depending on the accuracy of your measurements it could take decades to establish definitively that movement is occurring and by how much.

Na, unfortunately the majority of the people on this planet are extremely closed frame minded. Most people won't change their behavior if their life depended on it. In all likelihood most people just keep on doing what they're doing no matter what. Example: see what happened with Fukushima. One would think everybody would be shutting down nuclear reactors by now, but only one country, one that is run by a doctor in quantum chemistry, actually did it. Japan did not even change their nuclear policy, even though they are the ones being most directly screwed by the nuclear meltdown. George Soros in his book "The Alchemy of Finance" noted this unfortunate trait in human behavior. He went on to mention the only thing one can do is figure out what the trend as it will never change will transmute into.

[-] 1 points by ZenDog (13362) from South Burlington, VT 3 months ago

you completely ignore the fact that Global Warming is about to interrupt what most people have been doing, making it impossible for them to continue doing what they have been doing.

And that is really gonna piss them off.

.

And just think - it's only the average joe whose course of habit will change of necessity. Those wannabe mega rich people, those with vacation property by the sea but whom remain just too poor to purchase their own politicians, whom remain content to get their news from FUX, once half of their net wealth is eliminated by the rising tide, they're gonna be pissed too.

Personally, on a really sick and completely twisted level, I just can't wait.

[-] 2 points by Shule (1696) 3 months ago

Probably so. But unfortunately, by the time the idiots and assholes get interrupted from being idiots and assholes, the rest of us responsible folk will be screwed over by their actions long before that. And that's what's pissing me off.

At least we are beginning to see some push back from lame stream media on the issue. I personally don't care for the Dateline style of hour long coverage, all the repetition with every commercial break is tedious and very annoying, not to mention the false drama.

But Ann Curry did very good job with Our Year of Extremes last night, and kept the network nonsense to a minimum.

I confess I was very surprised to discover the lengths south Florida seems to be willing to go in an effort to keep the sea at bay - I'm convinced that at some point in the next 50 years we will see their efforts largely abandoned - but it was interesting all the same.
