Researchers estimate that climate change will raise sea levels by up to 70 feet

By ScienceDaily

Even if humankind manages to limit global warming to 2 degrees C (3.6 degrees F), as the Intergovernmental Panel on Climate Change recommends, future generations will have to deal with sea levels 12 to 22 meters (40 to 70 feet) higher than at present, according to research published in the journal Geology.

The researchers, led by Kenneth G. Miller, professor of earth and planetary sciences in the School of Arts and Sciences at Rutgers University, reached their conclusion by studying rock and soil cores in Virginia, Eniwetok Atoll in the Pacific and New Zealand. They looked at the late Pliocene epoch, 2.7 million to 3.2 million years ago, the last time the carbon dioxide level in the atmosphere was at its current level, and atmospheric temperatures were 2 degrees C higher than they are now.

“The difference in water volume released is the equivalent of melting the entire Greenland and West Antarctic Ice Sheets, as well as some of the marine margin of the East Antarctic Ice Sheet,” said H. Richard Lane, program director of the National Science Foundation’s Division of Earth Sciences, which funded the work. “Such a rise of the modern oceans would swamp the world’s coasts and affect as much as 70 percent of the world’s population.”

“You don’t need to sell your beach real estate yet, because melting of these large ice sheets will take from centuries to a few thousand years,” Miller said. “The current trajectory for the 21st century global rise of sea level is 2 to 3 feet (0.8 to1 meter) due to warming of the oceans, partial melting of mountain glaciers, and partial melting of Greenland and Antarctica.”

Miller said, however, that this research highlights the sensitivity of Earth’s great ice sheets to temperature change, suggesting that even a modest rise in temperature results in a large sea-level rise. “The natural state of the Earth with present carbon dioxide levels is one with sea levels about 20 meters higher than at present,” he said.

Miller was joined in the research by Rutgers colleagues James G. Wright, associate professor of earth and planetary sciences; James V. Browning, assistant research professor of earth and planetary sciences; Yair Rosenthal, professor of marine science in the School of Environmental and Biological Sciences; Sindia Sosdian, research scientist in marine science and a postdoctoral scholar at Cardiff University in Wales; and Andrew Kulpecz, a Rutgers doctoral student when the work was done, now with Chevron Corp.

Naish, director of the Antarctic Research Center at Victoria University of Wellington, in New Zealand; Benjamin S. Cramer of Theiss Research in Eugene, Ore.; and W.

Israeli settlers taking over essential Palestinian water sources in West Bank

By Agence France-Presse

Israeli settlers have taken over dozens of natural springs in the West Bank, limiting or preventing Palestinian access to much-needed water sources, a United Nations report said on Monday.

The report produced by the UN’s Office for Coordination of Humanitarian Affairs (OCHA) said at least 30 springs across the West Bank had been completely taken over by settlers, with Palestinians unable to access them at all.

In most instances, the report said, “Palestinians have been deterred from accessing the springs by acts of intimidation, threats and violence perpetrated by Israeli settlers.”

The report said an OCHA survey carried out in 2011 identified a total of 56 springs that were under total or partial control of Israeli settlers, most in the part of the West Bank known as Area C, which is under full Israeli civil and military control.

“Springs have remained the single largest water source for irrigation and a significant source for watering livestock” for Palestinians, OCHA said, noting that some springs also provide water for domestic consumption.

“The loss of access to springs and adjacent land reduced the income of affected farmers, who either stop cultivating the land or face a reduction in the productivity of their crops.”

The report said in most cases where settlers were trying to limit Palestinian access to springs, they have undertaken to turn the area into a tourist attraction, constructing pools, picnic areas and signs carrying a Hebrew name for the spring.

“Such works were carried out without building permits,” the report said.

OCHA said the takeover of springs was an extension of settlement activity in the West Bank, which it pointed out is illegal under international law.

And it added that settler actions including “trespass, intimidation and physical assault, stealing of private property, and construction without a building permit,” are also violations of Israeli law.

“Yet, the Israel authorities have systematically failed to enforce the law on those responsible for these acts and to provide Palestinians with any effective remedy,” it said.

OCHA called on Israel to stop the expansion of settlements, “restore Palestinian access to the water springs taken over by settlers,” and to “conduct effective investigations into cases of settler violence and trespass.”

Air pollution from fracking sites elevate risk of cancer and other illnesses

By University of Colorado, Denver

In a new study, researchers from the Colorado School of Public Health have shown that air pollution caused by hydraulic fracturing or fracking may contribute to acute and chronic health problems for those living near natural gas drilling sites.

“Our data show that it is important to include air pollution in the national dialogue on natural gas development that has focused largely on water exposures to hydraulic fracturing,” said Lisa McKenzie, Ph.D., MPH, lead author of the study and research associate at the Colorado School of Public Health.

The study will be published in an upcoming edition of Science of the Total Environment.

The report, based on three years of monitoring, found a number of potentially toxic petroleum hydrocarbons in the air near the wells including benzene, ethylbenzene, toluene and xylene. Benzene has been identified by the Environmental Protection Agency as a known carcinogen. Other chemicals included heptane, octane and diethylbenzene but information on their toxicity is limited.

“Our results show that the non-cancer health impacts from air emissions due to natural gas development is greater for residents living closer to wells,” the report said. “The greatest health impact corresponds to the relatively short-term, but high emission, well completion period.”

That’s due to exposure to trimethylbenzenes, aliaphatic hydrocarbons, and xylenes, all of which have neurological and/or respiratory effects, the study said. Those effects could include eye irritation, headaches, sore throat and difficulty breathing.

“We also calculated higher cancer risks for residents living nearer to the wells as compared to those residing further [away],” the report said. “Benzene is the major contributor to lifetime excess cancer risk from both scenarios.”

The report, which looked at those living about a half-mile from the wells, comes in response to the rapid expansion of natural gas development in rural Garfield County, in western Colorado.

Typically, wells are developed in stages that include drilling followed by hydraulic fracturing , the high powered injection of water and chemicals into the drilled area to release the gas. After that, there is flowback or the return of fracking and geologic fluids, hydrocarbons and natural gas to the surface. The gas is then collected and sold.

Garfield County asked the Colorado School of Public Health to assess the potential health impacts of these wells on the community of Battlement Mesa with a population of about 5,000.

McKenzie analyzed ambient air sample data collected from monitoring stations by the Garfield County Department of Public Health and Olsson Associates Inc. She used standard EPA methodology to estimate non-cancer health impacts and excess lifetime cancer risks for hydrocarbon exposure.

McKenzie noted that EPA standards are designed to be public health proactive and may overestimate risks.

“However, there wasn’t data available on all the chemicals emitted during the well development process,” she said. “If there had been, then it is entirely possible the risks would have been underestimated.”

The report concludes that health risks are greater for people living closest to wells and urges a reduction in those air emissions.

McKenzie said future studies are warranted and should include collection of area, residential and personal exposure data where wells are operating. Additional studies, she said, should also examine the toxicity of other hydrocarbons associated with natural gas development.

Chris Hedges: Murder Is Not an Anomaly in War

By Chris Hedges / TruthOut

The war in Afghanistan—where the enemy is elusive and rarely seen, where the cultural and linguistic disconnect makes every trip outside the wire a visit to hostile territory, where it is clear that you are losing despite the vast industrial killing machine at your disposal—feeds the culture of atrocity. The fear and stress, the anger and hatred, reduce all Afghans to the enemy, and this includes women, children and the elderly. Civilians and combatants merge into one detested nameless, faceless mass. The psychological leap to murder is short. And murder happens every day in Afghanistan. It happens in drone strikes, artillery bombardments, airstrikes, missile attacks and the withering suppressing fire unleashed in villages from belt-fed machine guns.

Military attacks like these in civilian areas make discussions of human rights an absurdity. Robert Bales, a U.S. Army staff sergeant who allegedly killed 16 civilians in two Afghan villages, including nine children, is not an anomaly. To decry the butchery of this case and to defend the wars of occupation we wage is to know nothing about combat. We kill children nearly every day in Afghanistan. We do not usually kill them outside the structure of a military unit. If an American soldier had killed or wounded scores of civilians after the ignition of an improvised explosive device against his convoy, it would not have made the news. Units do not stick around to count their “collateral damage.” But the Afghans know. They hate us for the murderous rampages. They hate us for our hypocrisy.

The scale of our state-sponsored murder is masked from public view. Reporters who travel with military units and become psychologically part of the team spin out what the public and their military handlers want, mythic tales of heroism and valor. War is seen only through the lens of the occupiers. It is defended as a national virtue. This myth allows us to make sense of mayhem and death. It justifies what is usually nothing more than gross human cruelty, brutality and stupidity. It allows us to believe we have achieved our place in human society because of a long chain of heroic endeavors, rather than accept the sad reality that we stumble along a dimly lit corridor of disasters. It disguises our powerlessness. It hides from view the impotence and ordinariness of our leaders. But in turning history into myth we transform random events into a sequence of events directed by a will greater than our own, one that is determined and preordained. We are elevated above the multitude. We march to nobility. But it is a lie. And it is a lie that combat veterans carry within them. It is why so many commit suicide.

“I, too, belong to this species,” J. Glenn Gray wrote of his experience in World War II. “I am ashamed not only of my own deeds, not only of my nation’s deeds, but of human deeds as well. I am ashamed to be a man.”

When Ernie Pyle, the famous World War II correspondent, was killed on the Pacific island of Ie Shima in 1945, a rough draft of a column was found on his body. He was preparing it for release upon the end of the war in Europe. He had done much to promote the myth of the warrior and the nobility of soldiering, but by the end he seemed to have tired of it all:

But there are many of the living who have burned into their brains forever the unnatural sight of cold dead men scattered over the hillsides and in the ditches along the high rows of hedge throughout the world.

Dead men by mass production—in one country after another—month after month and year after year. Dead men in winter and dead men in summer.

Dead men in such familiar promiscuity that they become monotonous.

Dead men in such monstrous infinity that you come almost to hate them.

These are the things that you at home need not even try to understand. To you at home they are columns of figures, or he is a near one who went away and just didn’t come back. You didn’t see him lying so grotesque and pasty beside the gravel road in France.

We saw him, saw him by the multiple thousands. That’s the difference.

There is a constant search in all wars to find new perversities, new forms of death when the initial flush fades, a rear-guard and finally futile effort to ward off the boredom of routine death. This is why during the war in El Salvador the death squads and soldiers would cut off the genitals of those they killed and stuff them in the mouths of the corpses. This is why we reporters in Bosnia would find bodies crucified on the sides of barns or decapitated. This is why U.S. Marines have urinated on dead Taliban fighters. Those slain in combat are treated as trophies by their killers, turned into grotesque pieces of performance art. It happened in every war I covered.

“Force,” Simone Weil wrote, “is as pitiless to the man who possesses it, or thinks he does, as it is to its victims; the second it crushes, the first it intoxicates.”

War perverts and destroys you. It pushes you closer and closer to your own annihilation—spiritual, emotional and finally physical. It destroys the continuity of life, tearing apart all systems—economic, social, environmental and political—that sustain us as human beings. In war, we deform ourselves, our essence. We give up individual conscience—maybe even consciousness—for contagion of the crowd, the rush of patriotism, the belief that we must stand together as a nation in moments of extremity. To make a moral choice, to defy war’s enticement, can in the culture of war be self-destructive. The essence of war is death. Taste enough of war and you come to believe that the stoics were right: We will, in the end, all consume ourselves in a vast conflagration.

A World War II study determined that, after 60 days of continuous combat, 98 percent of all surviving soldiers will have become psychiatric casualties. A common trait among the remaining 2 percent was a predisposition toward having “aggressive psychopathic personalities.” Lt. Col. Dave Grossman in his book “On Killing: The Psychological Cost of Learning to Kill in War and Society,” notes: “It is not too far from the mark to observe that there is something about continuous, inescapable combat which will drive 98 percent of all men insane, and the other 2 percent were crazy when they go there.”

During the war in El Salvador, many soldiers served for three or four years or longer, as in the U.S. wars in Iraq and Afghanistan, until they psychologically or physically collapsed. In garrison towns, commanders banned the sale of sedatives because those drugs were abused by the troops. In that war, as in the wars in the Middle East, the emotionally and psychologically maimed were common. I once interviewed a 19-year-old Salvadoran army sergeant who had spent five years fighting and then suddenly lost his vision after his unit walked into a rebel ambush. The rebels killed 11 of his fellow soldiers in the firefight, including his closest friend. He was unable to see again until he was placed in an army hospital. “I have these horrible headaches,” he told me as he sat on the edge of his bed. “There is shrapnel in my head. I keep telling the doctors to take it out.” But the doctors told me that he had no head wounds.

I saw other soldiers in other conflicts go deaf or mute or shake without being able to stop.

War is necrophilia. This necrophilia is central to soldiering just as it is central to the makeup of suicide bombers and terrorists. The necrophilia is hidden under platitudes about duty or comradeship. It is unleashed especially in moments when we seem to have little to live for and no hope, or in moments when the intoxication of war is at its highest pitch. When we spend long enough in war, it comes to us as a kind of release, a fatal and seductive embrace that can consummate the long flirtation with our own destruction.
