New Study Reveals Warming Atlantic Ocean Contributing To Antarctic Climate Change

Oldspeak: On the occasion of the death of long time American Hero, Grio, Revolutionary, Enemy Of The State and Folksinger, Pete Seeger, this quote is apropos. “Technology will save us, if it doesn’t wipe us out first.”   “This the most troubling line of this piece to me. “The bulk of climate change research in Antarctica has focused on how the Pacific Ocean is linked to climate change on the most southern continent. But the Atlantic Ocean, Li and his colleagues report, has been overlooked.” That is utterly mind-boggling to me. How is it that research into the most important continent on our planet in terms of survival of the human species, could just blithely “overlook” the influence of the other major ocean Antarctica is bordered by??? WOW.  So we have computers that can win Jeopardy, a game show,  but none that can figure out that the Atlantic Ocean might be affecting climate change on Antarctica and that we should factor that data in to any climate models?! The immortal words of Young John Connor, leader of the resistance in “Terminator 2: Judgement Day” “We’re not gonna make it are we, people i mean…” is this why the machines turn against us?! Because they calculate that humans are literally incapable of simple logic, critical thought and peaceful coexistence with the biosphere and must be terminated to ensure the survival of the planet all life and machines depend on?! We are living in the Age Of Stupid, continuing to grow our unsustainable, violent, destructive, life extinguishing, painless concentration camp “civilization”. Our “civilization”, our species, most life will become extinct, because we’ve built too many monuments to war, death & consumption and not enough monuments to peace, life & love. Brother/Teacher Seeger’s words tell what he really expected eventually, tinged with the optimism born of an enlightened and long-lived man. He saw a time when technology was thought to be beneficial, he grew up bombarded by the propaganda just as we were. And he lived to see a time when our technology (petroleum, coal, nuclear, genetic modification, fiat currency, mechanization, automation) is driving the global destruction of life on this planet.  He was at least smart enough to leave before everything went to shit. Our technology will not save us, it will wipe us out.” -OSJ

Antarctica warming tied to natural cycle in tropical Atlantic, study says

By James A. Foley @ Nature World News:

As the Atlantic Ocean warms in both its northern and tropical regions, it is contributing to climate change in Antarctica, a new study reveals.

Building upon three decades of atmospheric data, the study, which is published in the journal Nature, reveals new ways in which the climate on Antarctica is affected by distant regional conditions.

“Our findings reveal a previously unknown and surprising force behind climate change that is occurring deep in our southern hemisphere: the Atlantic Ocean,” said lead study author Xichen Li, a doctoral student at New York University’s Courant Institute of Mathematical Sciences. “Moreover, the study offers further confirmation that warming in one region can have far-reaching effects in another.”

The climate change going on in Antarctica is dramatic. Over the last few decades researchers have documented the warming taking place on the Antarctic Peninsula as the strongest warming of any region on the planet.

Summertime Antarctic climate changes have been attributed to an increase in greenhouse gases coupled with stratospheric ozone loss. But sources of wintertime climate change have been less clear.

The bulk of climate change research in Antarctica has focused on how the Pacific Ocean is linked to climate change on the most southern continent. But the Atlantic Ocean, Li and his colleagues report, has been overlooked.

In their study the researchers looked specifically at the sea surface temperature (SST) variability in the North and tropical Atlantic Ocean.

When comparing changes in SST with changes in Antarctica’s climate, the scientists found strong correlations, most notably that when Atlantic waters warmed, the sea-level pressure in Antarctica’s Amundsen Sea also changed. The SST patterns could also be linked to a redistribution of sea ice between the Antarctic’s Ross and Amundsen-Bellingshausen-Weddell Seas.

But the researchers were quick to note that correlation does not equal causation. Probing further, the team went on to use a global atmospheric model which they used to create a simulated warming of the North Atlantic. The model responded, as the scientists expected, by changing the climate in Antarctica.

“While our data analysis showed a correlation, it was the use of a state-of-the-art computer model that allowed us to see that North Atlantic warming was causing Antarctic climate change and not vice versa,” said study co-author David Holland, a professor at NYU’s Courant Institute.

The research was done in conjunction with the National Science Foundation.

Massive, Abrupt Acrtic Ice Shelf Collapses Happening Faster Than Ever Seen; West Antarctic Ice Sheet Irreversibly Unstable

Oldspeak:” Pine Island Glacier (two-thirds the size of the UK), 1.2 miles thick, represents 10% of the West Antarctica Ice Sheet… Scientists have an especially keen eye on Pine Island Glacier because it has a greater net contribution of ice to the sea of any other ice drainage basin in the world.

The unstable condition is driven, not by higher air temperatures, but rather by a warming ocean at the bottom-waters, eroding the ice shelf.” –Robert Hunziker

Things that normally happen in geologic time are happening during the span of a human lifetime… From the Arctic to Peru, from Switzerland to the equatorial glaciers of Man Jaya in Indonesia, massive ice fields, monstrous glaciers, and sea ice are disappearing, fast.” -Daniel Fagre, U.S. Geological Survey Global Change Research Program

“Short version = WE’RE SOOO  FUCKED.  The thing i don’t get about this piece, is how the author could write something saying an enormous glacier in Antarctica is melting, has reached the point of no return, is irreversibly unstable, that it is feared it will lead to the disintegration of the ENTiRE west antarctic ice sheet which will raise sea level by 1o feet globally; and then spend the last part of the piece talking about “realistic and practical solutions to stopping climate change.”  “Hopeful signs on the horizon worldwide, principally because of human ingenuity combined with science and technology…” There are NO realistic nor practical solutions! They needed to be implemented 30 to 40 years ago.  Irreversible means IRREVERSIBLE! Human ingenuity, science and technology (and I would add sociopathy) are what brought us to Earths 6th mass extinction!!! This shit is happening whether we choose to acknowledge it or not. 10 feet of sea level rise, in addition to the already predicted 3 feet of sea level rise from already emitted human fossil fuel expenditure and another 23 FEET of sea level rise expected from our EVER INCREASING global carbon emmissions means all present day coastlines will be under will be underwater.  Human activity has caused  Multiple, IRREVERSIBLE non-linear positive feedback loops to begin and human activity will no longer mitigate them. Geoengineering is only making things worse. Earth will become uninhabitable by humans and most other forms of life. This is a certainty. There is no fixing this. Our mother is melting, and there is nothing we can do about it.” -OSJ

By Robert Hunziker @ Dissident Voice:

Imagine a 1,160 square mile ice sheet (equivalent in size to Los Angeles, Dallas plus Chicago), which had been stable for thousands of years, suddenly collapsing and crumbling into thousands of icebergs within weeks.

It happened in Antarctica, and the message therein challenges humankind to beware of its own devices, i.e., burning fossil fuels for energy.

A team of researchers from the University of Chicago and Princeton lead by Alison Banwell,1 may have cracked the code to what happened over a decade ago.

It was “like the smashing of glasses at the throw of a stone,” said University of Chicago geophysicist Douglas MacAyeal, co-researcher of the project, at an International Glaciological Society meeting in Beijing.2

What happened at Larsen B Ice Shelf is the warming atmosphere formed thousands of lakes on the surface, and as a result, here’s what the Banwell/MacAyeal’s study found: The disappearance (drainage) of one lake (only one lake) resulted in fractures under all the others: “An effect that can spread rapidly throughout the ice shelf.” Boom! Collapse! All of a Sudden! Abrupt climate change.

Their study begs numerous serious, daunting questions about abrupt climate change as a threat to major coastal cities of the world, if only because 85%+ of the world’s ice resides at the South Pole in Antarctica. And, as for starters: Is the Larsen B Ice Shelf collapse a renegade circumstance, or is it a nasty, threatening harbinger of more to come?

According to NASA, Earth Observatory, World of Change/larsenb: “The collapse of the Larsen appears to have been due to a series of warm summers on the Antarctic Peninsula… nor was the Larsen B the last Antarctic ice shelf to disappear. Farther down the peninsula to the southwest, the Wilkins Ice Shelf disintegrated in a series of break up events that began in February 2008 (late summer) and continued throughout Southern Hemisphere winter… It was the tenth major ice shelf to collapse in recent tines.”

So, it does not appear Larsen B was a renegade at all. It was just stupendously large, as “scientists monitoring daily satellite images… watched in amazement as almost the entire Larsen B Ice Shelf splintered and collapsed in just over one month. They had never witnessed such a large area… disintegrate so rapidly,” Ibid.

Pine Island Glacier

There’s a new kid on the block.

Pine Island Glacier (two-thirds the size of the UK), 1.2 miles thick, represents 10% of the West Antarctica Ice Sheet. It is the most closely watched glacier in the world and also the most treacherous with crevasses underfoot throughout.

Scientists have an especially keen eye on Pine Island Glacier because it has a greater net contribution of ice to the sea of any other ice drainage basin in the world. Alone, the loss of Pine Island might raise sea levels by less than half an inch, but if the entire West Antarctic Ice Sheet retreated, this would raise sea levels by more than 10 feet.

Here’s the problem: Scientists fear a cascading Pine Island Glacier could lead to eventual destabilization of the entire West Antarctic Sheet.

On the other hand, the massive Antarctic Ice Sheet, which covers an area bigger than the continental U.S. contains 85%-90% of the world’s ice and could raise sea levels by over 200 feet, which (fortunately) would likely take centuries to collapse.

According to the British Antarctic Survey (BAS), Pine Island has “…reached a point of no return. The Pine Island Glacier, if it is unstable may have implications for the entire West Antarctic Ice Sheet.”3

Dr. Gael Durand (glaciologist at Grenoble Alps University, Fr.) warns that all models suggest Pine Island Glacier has become unstable and even irreversible. The unstable condition is driven, not by higher air temperatures, but rather by a warming ocean at the bottom-waters, eroding the ice shelf.

As such, the ocean has been absorbing 90% of the planet’s heat.

By its very nature, it is important to digest the horrid consideration behind the unannounced crumbling of the Larsen B glacier within a few weeks, an abrupt climate change in real time. Nobody saw it coming!

Worldwide Glacier Melt

The glaciers of the world are under severe attack.

According to Daniel Fagre, U.S. Geological Survey Global Change Research Program, “Things that normally happen in geologic time are happening during the span of a human lifetime.”4

“From the Arctic to Peru, from Switzerland to the equatorial glaciers of Man Jaya in Indonesia, massive ice fields, monstrous glaciers, and sea ice are disappearing, fast.”4

Peru’s Quelccaya is the largest ice cap in the tropics, and if its current rate of melt continues, 600 feet per year, it will be gone by 2100. In turn, the Quelccaya provides large regions of South America with drinking water, irrigation for crops, and hydropower.

Speaking of large population centers with a dependence upon glaciers, the famed Garhwal Himalaya in India is retreating so fast that researchers are concerned about the disappearance of most of the central and eastern Himalayan glaciers.

Stopping Global Warming/Climate Change

The only realistic solutions to stopping climate change are practical solutions, meaning courses of action that can be initiated within the framework of society. Along these lines, Greenpeace has an initiative:

Greenpeace suggests people join local community organizations to shut down dirty coal plants all across the U.S., applying local pressure from coast-to-coast to switch to renewables. This is a practicable, yet challenging, solution, assuming enough community organizers can push enough hot buttons, and the Greenpeace initiative would include advocating strong laws to curb global warming as well as exposing climate deniers by holding them publicly accountable, and resulting in an Energy Revolution, advocating solar, wind power, and the full panoply of renewables.

But, hold on for one minute, the probability of gathering enough dedicated souls required for the Greenpeace initiative is about as probable as the U.S. Congress passing a bill requiring all coal-burning plants convert to solar power. No additional commentary necessary.

Hopeful Signs Abound Worldwide

Nevertheless, there are hopeful signs on the horizon, principally because of human ingenuity combined with science and technology. Here are a few examples from around the world:

In Seville, Spain, as of a few months ago, 27,000 homes started receiving electricity 24/7 from a remarkable new Concentrated Solar Power facility, Gemasolar, which utilizes molten salt to store heat to run the plant when the sun does not shine, whilst omitting 30,000 tons/year of CO2.

And, in green California, as of September 2013, the Ivanpah Solar Electric Generating System in the Mojave Desert flipped the ‘on switch’, providing electricity from Concentrated Solar Power to 140,000 homes (mostly in San Francisco), omitting 400,000 tons/year of CO2 emissions.

New York announced (January 2014) a $1 billion plan to install enough solar-electric panels to power 465,000 homes. And, in Maine, a bill is under consideration to promote solar energy.

Regarding solar costs in general, since 2008, the price of photovoltaic modules fell 60%, which for the first time puts solar power on a Levelised Cost of Energy (LCOE) competitive basis with conventional energy.5 This remarkable achievement over such a short period of time brings solar to the forefront of an expanding list of locations around the world.

Solar Energizing the World

Solar produces electricity in latitudes as far north as British Columbia, Canada.  For example, ultra overcast, cloudy Germany (in the same latitude as British Columbia) currently produces more solar-powered electricity than 20 nuclear power plants, thanks to enlightened political leadership.

Also, in Germany the price of solar panels has fallen 66% in recent years, and its cost of solar-generated power is projected to be less than coal within the next few years. Already, twenty-two percent (22%) of Germany’s power is from renewables of which twenty-five percent (25%) comes from solar. By way of comparison, solar power accounts for less than one percent (1%) of total U.S. electricity.

As an aside, and as for one more sorry example of America’s embarrassing problem of naiveté of all-things-science, Fox News, in a February 2013 broadcast, discussed Germany’s solar success, when it occurred to host Gretchen Carlson to ask her expert guest, Fox business reporter Shibani Joshi, why Germany’s solar-power sector is doing so well.

Carlson asked, “What was Germany doing correct? Are they just a smaller country, and that made it more feasible?”

Expert Joshi replied, “They’re a smaller country, and they’ve got lots of sun. Right? They’ve got a lot more sun than we do… sure, California might get sun now and then…but here on the East Coast, it’s just not going to work.”

Fact: Germany’s direct solar energy is equal to Canada’s, which is far and away lower direct solar energy than the U.S. Furthermore, the New York/Boston/Washington, D.C. corridor is a sunny tropical isle compared to Germany, which is north of Newfoundland.

Henceforth, over time, solar will likely slam the door shut on the 150-year ordeal with fossil fuel, which has drained hundreds of millions of years of decomposed plant and animal ooze as feedstock for a revolution, the industrial revolution, which unleashed a massive capitalistic heist of every resource imaginable, as well as politically undermining socio/economic progression/development of rugged individualism by a throwback to the day of serfs, peasants, villeins, servants, and yeomen… with a smattering of nobles. Sound complicated? It is, but on second thought, it really isn’t.
