Ozone Hole Science Revisited

Scientists are commemorating the discovery 20 years ago that man-made chlorofluorocarbons (CFCs) used chiefly in refrigerators and air-conditioners were responsible for creating the "ozone hole" over the Antarctic. The scientists concluded that CFCs would drift into the stratosphere where they would produce chlorine compounds that react with ice particles and sunlight to efficiently destroy ozone molecules that shield the surface from ultraviolet light streaming from the sun. In 1987, the world adopted the Montreal Protocol to eventually eliminate the production of CFCs. Activists often cite the Montreal Protocol as a model for a future treaty addressing man-made global warming by banning the emission of greenhouse gases. A Nobel Prize in chemistry was awarded in 1995 to the three scientists who identified the ozone/CFC connection.

This neat story of the scientific identification of a man-made cause for stratospheric ozone depletion followed by a successful international response to the threat is now being challenged by some very recent research. News@nature.com (sub required) is reporting a new analysis by Markus Rex, an atmosphere scientist at the Alfred Wegener Institute of Polar and Marine Research in Potsdam, Germany, which finds that the data for the break-down rate of a crucial molecule, dichlorine peroxide (Cl2O2) is almost an order of magnitude lower than the currently accepted rate.

What this could mean according to the Nature news article is that:

"This must have far-reaching consequences," Rex says. "If the measurements are correct we can basically no longer say we understand how ozone holes come into being." What effect the results have on projections of the speed or extent of ozone depletion remains unclear.

The rapid photolysis of Cl2O2 is a key reaction in the chemical model of ozone destruction developed 20 years ago2 (see graphic). If the rate is substantially lower than previously thought, then it would not be possible to create enough aggressive chlorine radicals to explain the observed ozone losses at high latitudes, says Rex. The extent of the discrepancy became apparent only when he incorporated the new photolysis rate into a chemical model of ozone depletion. The result was a shock: at least 60% of ozone destruction at the poles seems to be due to an unknown mechanism, Rex told a meeting of stratosphere researchers in Bremen, Germany, last week.

Other groups have yet to confirm the new photolysis rate, but the conundrum
is already causing much debate and uncertainty in the ozone research community. "Our understanding of chloride chemistry has really been blown apart," says John Crowley, an ozone researcher at the Max Planck Institute of Chemistry in Mainz, Germany.

"Until recently everything looked like it fitted nicely," agrees Neil Harris, an atmosphere scientist who heads the European Ozone Research Coordinating Unit at the University of Cambridge, UK. "Now suddenly it's like a plank has been pulled out of a bridge." ...

Nothing currently suggests that the role of CFCs must be called into question, Rex stresses. "Overwhelming evidence still suggests that anthropogenic emissions of CFCs and halons are the reason for the ozone loss. But we would be on much firmer ground if we could write down the correct chemical reactions."

Of course, it may be that Rex's research has gone wrong somehow or that another chemical mechanism involving CFCs will turn out to be chiefly responsible for ozone depletion. Nevertheless, it is good to keep in mind that all scientific results are provisional and may change in the light of new evidence.

By the way, for anyone who cares about my own take on the ozone hole/CFC issue, in chapter 8 of my 1993 book, Eco-Scam: The False Prophets of Ecological Apocalypse, I concluded:

Despite a great deal of continuing scientific uncertainty, it appears that CFCs do contribute to the creation of the Antarctic ozone hole and perhaps to a tiny amount of global ozone depletion. If CFCs were allowed to build up in the atmosphere during the next century, ozone depletion might eventually entail significant costs. More ultraviolet light reaching the surface would require adaptation—switching to new crop varieties, for example—and it might boost the incidence of nonfatal skin cancer. In light of these costs, it makes sense to phase out the use of CFCs.

Calories underestimated in "healthy" restaurants

NEW YORK (Reuters Health) - People who opt for a meal at a "healthy" restaurant often consume more calories than they would dining at fast food joints that make no health claims, a new study shows.

The researchers found that individuals underestimate the calorie content of foods served at restaurants they see as healthier, to a degree that could easily lead to weight gain.

For example, "People think that the same 1,000-calorie meal has 159 fewer calories if it comes from Subway than if it comes from McDonalds," Dr. Pierre Chandon, at INSEAD in Fontainebleau, France, told Reuters Health. "If they choose to consume this fictitious 'calorie credit' on other food, and it they eat at Subway twice a week, they could gain an extra 4.9 pounds a year."

While restaurants presenting themselves as healthy have grown at a much faster rate over the past five years than traditional fast food restaurants, Americans' waistlines have not been shrinking; in fact, the nation's population is fatter than ever, note Chandon and his colleague Dr. Brian Wansink of Cornell University in Ithaca in their report in the Journal of Consumer Research.

The researchers theorized that people might take in more calories when they eat in "healthy" restaurants, and conducted a series of studies to test this notion.

In the first, they asked people who had just finished eating at Subway or McDonalds to estimate how many calories they had just consumed. On average, Subway patrons rated their meals as having 151 fewer calories than did McDonalds patrons. In fact, for a meal at either restaurant containing 1,000 calories, people would estimate it to contain 744 calories if they'd eaten at McDonalds and 585 calories if they'd dined at Subway.

In the second experiment, they asked people to estimate the calorie content of four different sandwiches: a six-inch ham and cheese sandwich (330 calories) and a 12-inch turkey sandwich (600 calories) from Subway; and a McDonalds cheeseburger (330 calories) and a Big Mac (600 calories). Study participants consistently rated the Subway sandwich as having fewer calories than the McDonalds sandwich with the same calorie content.

Next, the researchers offered people a coupon for a Big Mac (600 calories) or a Subway 12-inch Italian BMT sandwich (900 calories), and asked them whether they would like to order a drink or cookies with their sandwich. People eating the Subway sandwich were more likely to choose a large drink, less likely to opt for diet soda, and more likely to get cookies. This meant that, on average, they wound up consuming 1,011 calories, compared to 648 calories for the people given a McDonalds coupon.

People who want to control their weight or trim down need to think objectively about calorie content, and not let their perceptions be clouded by whether a food is supposed to be good or bad for them, Chandon said. "We have to move away from thinking of food in 'good food / bad food' (terms) and think also about 'how much food.' In France, for example, people enjoy relatively fat diets but are less overweight simply because portion sizes in restaurants and at home are smaller."

Chandon suggested one technique to help people judge calorie counts more accurately: "Instead of estimating the number of calories of the whole meal (which leads to undercounting) look at the sandwich, the side, the beverages, and the drink and add that up. Our research showed that this 'piecemeal' method is very effective."

Doctors refuse to fix builder's broken ankle unless he quits smoking

A man with a broken ankle is facing a lifetime of pain because a Health Service hospital has refused to treat him unless he gives up smoking.

John Nuttall, 57, needs surgery to set the ankle which he broke in three places two years ago because it did not mend naturally with a plaster cast.

Doctors at the Royal Cornwall Hospital in Truro have refused to operate because they say his heavy smoking would reduce the chance of healing, and there is a risk of complications which could lead to amputation.


They have told him they will treat him only if he gives up smoking. But the former builder has been unable to break his habit and is now resigned to coping with the injury as he cannot afford private treatment.

He is in constant pain from the grating of the broken bones against each other and has been prescribed daily doses of morphine.

Mr Nuttall, of Newlyn, Cornwall, broke the ankle in a fall in 2005. Initially he refused surgery because he had caught MRSA at a different hospital four years earlier, and was terrified of history repeating itself.

He hoped the fractured bones would knit together with a standard plaster cast to immobilise his ankle.

But six months and three plaster casts later, it became clear that an operation to pin the bones was the only solution.


However, the hospital told Mr Nuttall, who no longer works because of smoking-related chest problems, that he would have to give up smoking before an operation could be carried out.

Mr Nuttall said: '"I am in agony. I have begged them to operate but they won't. I have tried my hardestto give up smoking but I can't. I got down to ten a week at one point but they said that was not good enough.

"I spent 12 months trying to give up and used patches and everything, but nothing works.

"I have smoked for over 40 years and it's not going to happen.

"We were brought up at a time when cigarette advertisements were everywhere and there were no warnings.

"I want to warn other smokers that they could be denied medical treatment and there is nothing we can do about it.

"I have paid my dues as a taxpayer-and now the NHS won't treat me."

Mr Nuttall, who is single, uses a walking stick to get around and fears his bones will now be so 'calcified' that an operation would not work even if he were allowed to have it.

"It is very painful," he said. "If I walk more than a few steps I can feel it grinding."

A spokesman for the hospital trust said: "Smoking has a very big influence on the outcome of this type of surgery, and the healing process would be hindered significantly."

The World's Wealthiest Poor

Robert Rector of the Heritage Foundation is a national authority on poverty and the U.S. welfare system. Specializing in welfare reform and family breakdown, Rector has done extensive research on the economic and social costs of welfare.

With presidential candidates of a certain hue decrying the suffering of the 37 million Americans who have been officially classified as poor by the U.S. Census Bureau, we thought we'd ask Rector if these poor people are really as poverty-stricken as we have been led to believe. I talked to the author of “America's Failed $5.4 Trillion War on Poverty” Thursday, Sept. 6, by telephone from his office in Washington:

Q: John Edwards and others lament that 37 million Americans struggle with incredible poverty every day. You say it is not so simple or accurate to think of them as truly poor. What do you mean?
A: Well, when John Edwards says that one in eight Americans do not have enough money for food, shelter or clothing, that’s generally what the average citizen is thinking about when they hear the word “poverty.” But if that’s what we mean by poverty, then virtually none of these 37 million people that are ostensibly poor are actually poor. In reality, the government runs multiple surveys that allow us to examine the physical living conditions of these individuals in great detail.

When you look at the people who John Edwards insists are poor, what you find is that the overwhelming majority of them have cable television, have air conditioning, have microwaves, have two color TVs; 45 percent of them own their own homes, which are typically three-bedroom homes with 1.5 baths in very good recondition. On average, poor people who live in either apartments or in houses are not crowded and actually have more living space than the average person living in European countries, such as France, Italy or England.

Also, a lot of people believe that poor people are malnourished. But in fact when you look at the average nutriment intake of poor children, it is virtually indistinguishable from upper-middle-class children. In fact, poor kids by the time they reach age 18 or 19 are taller and heavier than the average middle-class teenagers in the 1950s at the time of Elvis. And the boys, when they reach 18, are a full one inch taller and 10 pounds heavier than the GIs storming the beaches of Normandy. It’s pretty hard to accomplish that if you are facing chronic food shortages throughout your life.

Q: How many Americans would you define as “truly poor”?
A: If you are looking at people who do not have adequate warm, dry apartments that are in good repair, and don’t have enough food to feed their kids, you’re probably looking at one family in 100, not one family in eight.

Q: Who are these “truly poor” and where do they live?
A: Generally, they will be families that have a whole lot of behavioral issues in addition to mere economic issues -- possibly drug problems, mental problems, certainly very low work effort, probably unmarried mothers and so forth. They would be spread around the country. Very few of them are elderly. Even though the elderly appear to have low incomes, they are not likely to lack food or to have a hole in their roof or things like that.

Q: Is there any single reason why the “official poor” are poor?
A: If you look at the official poor, particularly at children who are officially in poverty, there are two main reasons for that. One is that their parents don’t work much. Typically in a year, poor families with children will have about 16 hours of adult work per week in the household. If you raised that so that you had just one adult working full time, 75 percent of those kids would immediately be raised out of poverty.

The second major reason that children are poor is a single parenthood in the absence of marriage. Close to two-thirds of all poor children live in single-parent families. What we find is that if a never-married mother married the father of her children, again, about 70 percent of them would immediately be raised out of poverty. Most of these men who are fathers without being married in fact have jobs and have a fairly good capacity to support a family.

Q: How many of those 37 million are children -- and why do they count them as poor people?
A: They are counted as part of the household -- what they judge is the whole household’s income. Part of the reason the Census Bureau is telling us that we have 37 million poor people is that it judges families to be poor if they have incomes roughly less than $20,000 a year. But it doesn’t count virtually any welfare income as income. So food stamps, public housing, Medicaid -- all of the $600 billion that we spend assisting poor people (per year) is not counted as income when they go to determine whether a family is poor.

Q: Are these 37 million officially poor people the same people year after year, decade after decade?
A: Not exactly. Some of them are just down there temporarily. Others tend to be in poor or near-poor status for a long time. That would tend to be true of single mothers, for example. ... But vis-a-vis the single mothers, it’s important to understand that 38 percent of all children are born to a mother who is not married and in half of the cases she is actually living with the father and the couple will express an interest in marriage but it never actually happens. One of the simplest and most important things we could do to reduce child poverty would be to go and communicate to those couples -- all of whom are low-income -- the importance of marriage for their own well-being and for the child’s well-being.

Q: You don't make these numbers up -- you rely on information provided by the Census Bureau. So how does this myth of the poor never seem to be debunked or straightened out in the media?
A: All of the data I provide come directly from government surveys. Those government surveys are not heavily publicized by the media, because since the beginning of the War on Poverty the politically correct thing to do is to just exaggerate the amount of poverty that exists in the United States as a way of encouraging more welfare spending.

Q: You said we're spending $600 billion a year?
A: That’s what we are spending on cash, food, housing and medical care. The biggest program in there is Medicaid, followed by something called the “earned income tax credit.” The federal government, with state governments, runs 70 different means-tested welfare programs. These are programs that provide assistance exclusively to poor and low-income Americans.

Q: How much of this money actually gets to the poor people who need it and how much is overhead?
A: Most of the money goes directly to poor people either as services or as something like a food stamp or medical care. The problem with these programs is that they reward individuals for not working and not being married. Essentially, they set up a very negative set of incentives that tends to push people deeper into poverty rather than helping them climb out of it.

The problem with the welfare state is not that it has huge overhead costs. In fact, the overhead costs are only about 15 percent of total costs. The problem is that aid is given in such a way that it encourages dependence rather than helping people to become self-sufficient.

Q: I’ve read that the national poverty rate declined steadily until it hit about 13 percent in about 1965. It’s been stuck there since, despite trillions of dollars in welfare spending. Is this true -- and why?
A: Yes. Poverty was declining rapidly before the War on Poverty was created in the mid-1960s, and since that time the poverty rate has basically stagnated. There are two reasons for that. One is that none of the poverty spending is counted as income, so that it can’t have an anti-poverty effect. But the second, more important reason is that all of these programs discourage work and marriage, so that they in fact are pushing people deeper into poverty at the same time that they are giving them aid.

Q: So it is true that the official poverty rate is stuck at about 12 or 13 percent?
A: It hasn’t varied terribly much since the beginning of the War on Poverty.

Q: Despite how many trillions being spent?
A: Since the beginning of the War on Poverty we have now spent over 11 trillion dollars.

Q: Where did that money go -- and who got it?
A: Basically, we have spent a lot of money but we spent money in such a way that we displaced the work effort of the poor, so that we did not get very much net increase in income. Rather than bringing people’s incomes up, what we’ve done is supplanted work with welfare. What you need to do in order to truly get improvements is to create a welfare system that requires work and encourages marriage so that the recipient is moving toward self-sufficiency while receiving aid, rather than receiving aid in lieu of his own work efforts.

Q: We’ve known for a long time about these problems with the welfare system. Is there any progress being made to fix them?
A: In 1996, we reformed one small welfare program -- Aid to Families with Dependent Children -- by requiring the recipients or part of the recipients to perform work in exchange for the benefits.

As a result of that, we got a huge decline in welfare rolls, a huge surge in employment and record drops in black child poverty. Unfortunately, the rest of the welfare system -- the remaining 69 programs -- remained unreformed. Until we reform those programs in a similar way, we will make no further progress against poverty.

Disturbed anti-war protester can't find soldier, kills civilian with axe instead

AMSTERDAM, Netherlands (AP) - A U.S. citizen has confessed to using an axe to kill a Dutch student after failing to find a soldier to attack, his lawyer said Tuesday.

The suspect, Carlos Hartmann, 41, of Tecumseh, Mich., has confessed to the Sept. 8 killing on a train platform in the southern city of Roosendaal, defence lawyer Peter Gremmen said.

Gremmen said Hartmann wanted to punish the Netherlands for its support of the war in Iraq.

Hartmann appeared before a judge Tuesday and was ordered held for another two weeks for investigation.

"He hates soldiers, and says that the army kills people, so it would be legitimate if he were also to kill someone . . . from the American military - or from its NATO allies," Gremmen said in a telephone interview.

When he failed to find a soldier at the Roosendaal train station, "he got such a crazy, disturbed idea that he killed a civilian," Gremmen said.

Hartmann did not attempt to escape and was arrested shortly after the killing.

Dutch prosecutors confirmed that the suspect had confessed but did not identify him or his victim, in keeping with Dutch practice.

Under the Dutch legal system, Hartmann was not required to enter a plea Tuesday.

Prosecution spokeswoman Martine Pilaar said her office was taken aback by the defence lawyer's willingness to disclose details of his case.

But Gremmen said he was only confirming details published by the local newspaper BN/De Stem. The paper's source was not named, and police declined to comment.

"I was also surprised when I saw the paper; I thought, this must be coming from the investigation," the lawyer said.

Gremmen said Hartmann has lived in the Netherlands since 2002, supporting himself with English editing work for a Japanese company, which he could do by computer, and that he had no fixed address.

He said Hartmann had consented to undergo psychological testing, and was now "terribly sorry for his deed."

The victim, identified as Thijs Geers, was waiting for a train and had no connection with the suspect or the military. Online condolence registers in the Netherlands were flooded with messages of sympathy for him and his family.

BN/De Stem quoted a witness who asked to remain anonymous as describing Hartmann as striking the victim in the back of the head with the axe. It also quoted an unidentified family member from the United States as saying Hartmann has suffered from emotional problems since his early 20s.

"It's a sad story," Gremmen said. "But I'm glad he's admitted what he's done and that he's sorry for it."

Biofuels may harm more than help

By Sybille de La Hamaide

PARIS (Reuters) - Biofuels, championed for reducing energy reliance, boosting farm revenues and helping fight climate change, may in fact hurt the environment and push up food prices, a study suggested on Tuesday.

In a report on the impact of biofuels, the Organization for Economic Cooperation and Development (OECD) said biofuels may "offer a cure that is worse than the disease they seek to heal".

"The current push to expand the use of biofuels is creating unsustainable tensions that will disrupt markets without generating significant environmental benefits," the OECD said.

"When acidification, fertilizer use, biodiversity loss and toxicity of agricultural pesticides are taken into account, the overall environmental impacts of ethanol and biodiesel can very easily exceed those of petrol and mineral diesel," it added.

The OECD therefore called on governments to cut their subsidies for the sector and instead encourage research into technologies that would avoid competing for land use with food production.

"Governments should cease to create new mandates for biofuels and investigate ways to phase them out," it said.

The OECD said tax incentives put in place in many regions, including the European Union and the United States, to encourage biofuel output could hide other objectives.

"Biofuel policies may appear to be an easy way to support domestic agriculture against the backdrop of international negotiations to liberalize agricultural trade," it said.

CUT DEMAND

Instead it encouraged members of the World Trade Organization to step efforts to lower barriers to biofuel imports to allow developing countries that have ecological and climate systems more suited to biomass production.

The OECD also encouraged government to work on cutting demand for transport fuel rather than encouraging production of so-called "green" fuels.

"A liter of gasoline or diesel conserved because a person walks, rides a bicycles, carpools or tunes up his or her vehicle's engine more often is a full liter of gasoline or diesel saved at a much lower cost to the economy than subsidizing inefficient new sources of supply," it said.

Biofuels, made mainly from grains, oilseeds and sugar, have been accused of being responsible for a recent surge in farm commodities prices, along with other factors such as lower output and tight stocks.

The OECD, which said in July that it saw biofuels keeping prices at high levels into the next decade, said it would lead to an unavoidable "food-versus-fuel" debate.

"Any diversion of land from food or feed production to production of energy biomass will influence food prices from the start, as both compete for the same input," it said.

Obscene fans at Rutgers draw a penalty flag

Tuesday, September 11, 2007

The play came late in the game, when Rutgers expanded its lead over Navy to a comfortable level after a tight three quarters.

Navy's Reggie Campbell took the kickoff and ran full speed ahead up the middle with all the force his 168-pound body could generate. Campbell, almost always the smallest and fastest man on the field, hit a wall of XXXL-sized scarlet jerseys and was slammed to the ground at the bottom of the pile. He got up slowly, limping off. This gutsy kid, a slotback who already spent three quarters being chased and tackled by gangs of defensive linemen and linebackers, all weighing at least 100 pounds more than him, was then given a dose of Rutgers' student section class.

''You got f---ed up. You got f---ed up. You got f--ed-up," they chanted.

Reggie Campbell is a senior. After graduation in June he has a five-year commitment to the American military, which, like it or not, is at war.

"This is how you treat people who may die for this country?" said Bill Squires, an Annapolis graduate (Class of'75) who was on the sidelines for the Friday night game in Piscataway and was shocked by the obscene chants directed at the Navy players and fans throughout the game. "It was the most classless thing I've seen."

Navy was booed and peppered with "You suck!" chants when they stepped on the field for both halves. Toward the end of the second half, Rutgers students in the new bleacher section began to serenade the adjacent section of Navy fans and uniformed Midshipmen.

''F--- you, Navy. F---you, Navy. F--- you, Navy."

"There were wives and small children up there," said Squires, an academic recruiter for the academy who has been to dozens of away games and never seen such contempt directed at his team. "Our Midshipmen reacted the way they were taught. They didn't respond, but the band started playing 'Anchors Aweigh' to drown them out. Me, I felt like going up there and smacking somebody. I was mad, and it bothered me all weekend."

Booing, cursing, chanting obscenities, unfortunately, are now part of the game day experience. It's easily been three decades since fans across the country in all sports began spending more time and creative energy jeering the visitors and officials than cheering the home team. Rutgers is far from the worst. They're not even the worst in New Jersey, not with the Jets' fans still in town. Still, every penalty against the Scarlet Knights is greeted with a chant of "a--hole, a--hole, a--hole."

And now that Rutgers is winning, the long-suffering, self-effacing adult fans are being drowned out by a new generation of weight-room bully boys in scarlet T-shirts and red face-paint, who, from the safety of their seats, belittle the guys down on the field who take the hits.

Now that Rutgers is big-time, the old-time academic- and adult-minded fans are being elbowed aside by gangs of frat boys thrusting their fists and faces into the rolling ESPN cameras. What was it your old football coach used to say? Act like you've been there before. Not in the RU student section.

"At one point, I thought, we defend this country for people like this?" said Squires, who lives in West Orange. "I wasn't embarassed as a New Jerseyan. I was embarassed as a human being."

It was so noticeable that Rutgers athletic director Bob Mulcahy called down to Navy athletic director Chet Gladchuk yesterday to make sure there were no hard feelings, according to John Wooding, an assistant AD at Rutgers.

Some will excuse the behavior as kids just being kids, out to have a loutish, drunken good time. Spewing obscenities at the visiting team is just part of the fun.

But you'd hope our Jersey kids would be smart enough to make an exception for the service academies, especially the weekend before the anniversary of Sept. 11, their generation's own Day of Infamy. You'd hope they'd be sensitive enough to realize that some of those Midshipmen may soon be among the young American men and women fighting and bleeding and dying in Iraq and Afghanistan. Young Americans, the same age as those safe in the stands watching a football game with their faces and bodies painted red.

At the very least, you'd think the Rutgers students would have some appreciation for the effort the undersize Navy players put out. They aren't like the players from Louisville or West Virginia or some of the other ranked powerhouses Rutgers now finds itself among. They are what Rutgers was not so many years ago. Students first, athletes second. Except better.

The new Rutgers is a big-time football school, with all the hype and manufactured drama. Coach Greg Schiano leads his team through pregame Scarlet Walk, chest out, stomach in, looking every bit the general except without gold braids, epaulets and a full rack of medals. The band plays. The cheerleaders and dance team girls wave pompoms. The conquering heroes go past, eyes front. At game time, the scoreboard TV shows the team coming down the tunnel to a soundtrack from Armageddon. An Army helicopter chop-chops overhead (your tax dollars at work).

Football has always marched to a militaristic or tribal drum beat, to whip up players to greater levels of violence. The game is always likened to war by coaches, players, announcers and writers who haven't been to war.

But to Reggie Campbell and his Navy teammates, Friday night's game wasn't war. It was a game. War is around the bend.

They deserved better.

And that red on the faces of some Rutgers' fans wasn't body paint.
