British nationalist green movement from the 1920s A History of the Kibbo Kift
A History of the Kibbo Kift: On August 18, 1920, a group of young men met in a London hall to formalise the foundation of a new movement to be known as the Kindred of the Kibbo Kift. The aims of this movement had been written down two months earlier in the form of a seven-point Covenant, which ran as follows:
* Open Air Education for the Children. Camp Training and Naturecraft.
* Health of Body, Mind and Spirit.
* Craft Training Groups and Craft Guilds.
* The Woodcraft Family, or Roof Tree.
* Local Folk Moots and Cultural Development.
* Disarmament of Nations - Brotherhood of Man.
* International Education based on these points.
o Freedom of Trade between Nations.
o Stabilisation of the Purchasing Power of Money in all countries.
o Open Negotiations instead of secret treaties and diplomacy.
o A World Council.

The Himalayas and nearby peaks have lost no ice in past 10 years, study shows
Meltwater from Asia's peaks is much less then previously estimated, but lead scientist says the loss of ice caps and glaciers around the world remains a serious concern

The world's greatest snow-capped peaks, which run in a chain from the Himalayas to Tian Shan on the border of China and Kyrgyzstan, have lost no ice over the last decade, new research shows.
The discovery has stunned scientists, who had believed that around 50bn tonnes of meltwater were being shed each year and not being replaced by new snowfall.
The study is the first to survey all the world's icecaps and glaciers and was made possible by the use of satellite data. Overall, the contribution of melting ice outside the two largest caps – Greenland and Antarctica – is much less then previously estimated, with the lack of ice loss in the Himalayas and the other high peaks of Asia responsible for most of the discrepancy.
Bristol University glaciologist Prof Jonathan Bamber, who was not part of the research team, said: "The very unexpected result was the negligible mass loss from high mountain Asia, which is not significantly different from zero."
The melting of Himalayan glaciers caused controversy in 2009 when a report from the UN's Intergovernmental Panel on Climate Change mistakenly stated that they would disappear by 2035, instead of 2350. However, the scientist who led the new work is clear that while greater uncertainty has been discovered in Asia's highest mountains, the melting of ice caps and glaciers around the world remains a serious concern.
"Our results and those of everyone else show we are losing a huge amount of water into the oceans every year," said Prof John Wahr of the University of Colorado. "People should be just as worried about the melting of the world's ice as they were before."
His team's study, published in the journal Nature, concludes that between 443-629bn tonnes of meltwater overall are added to the world's oceans each year. This is raising sea level by about 1.5mm a year, the team reports, in addition to the 2mm a year caused by expansion of the warming ocean.
The scientists are careful to point out that lower-altitude glaciers in the Asian mountain ranges – sometimes dubbed the "third pole" – are definitely melting. Satellite images and reports confirm this. But over the study period from 2003-10 enough ice was added to the peaks to compensate.
The impact on predictions for future sea level rise is yet to be fully studied but Bamber said: "The projections for sea level rise by 2100 will not change by much, say 5cm or so, so we are talking about a very small modification." Existing estimates range from 30cm to 1m.
Wahr warned that while crucial to a better understanding of ice melting, the eight years of data is a relatively short time period and that variable monsoons mean year-to-year changes in ice mass of hundreds of billions of tonnes. "It is awfully dangerous to take an eight-year record and predict even the next eight years, let alone the next century," he said.
The reason for the radical reappraisal of ice melting in Asia is the different ways in which the current and previous studies were conducted. Until now, estimates of meltwater loss for all the world's 200,000 glaciers were based on extrapolations of data from a few hundred monitored on the ground. Those glaciers at lower altitudes are much easier for scientists to get to and so were more frequently included, but they were also more prone to melting.
The bias was particularly strong in Asia, said Wahr: "There extrapolation is really tough as only a handful of lower-altitude glaciers are monitored and there are thousands there very high up."
The new study used a pair of satellites, called Grace, which measure tiny changes in the Earth's gravitational pull. When ice is lost, the gravitational pull weakens and is detected by the orbiting spacecraft. "They fly at 500km, so they see everything," said Wahr, including the hard-to-reach, high-altitude glaciers.
"I believe this data is the most reliable estimate of global glacier mass balance that has been produced to date," said Bamber. He noted that 1.4 billion people depend on the rivers that flow from the Himalayas and Tibetan plateau: "That is a compelling reason to try to understand what is happening there better."
He added: "The new data does not mean that concerns about climate change are overblown in any way. It means there is a much larger uncertainty in high mountain Asia than we thought. Taken globally all the observations of the Earth's ice – permafrost, Arctic sea ice, snow cover and glaciers – are going in the same direction."
Grace launched in 2002 and continues to monitor the planet, but it has passed its expected mission span and its batteries are beginning to weaken. A replacement mission has been approved by the US and German space agencies and could launch in 2016.

Polar Bears Thrive, Contrary to WWF Claims
Polar Bears Thrive, Contrary to WWF Claims: You've probably seen the commercials; TV actor Noah Wyle (ER, The Librarian) somberly informs us of an impending grave catastrophe: "A tragedy is unfolding in the world today. Climate change is threatening one of the most magnificent wild animals on the planet. Polar bears. They're struggling to survive."
Heart-tugging violins accompany video footage of a mother polar bear and her cuddly cub on a small ice flow.
The ice is melting all around them and food is becoming harder to find as they lose their hunting grounds. Climate change. It's happening right now and its leaving mothers weaker and unable to provide for their young and cubs dying without enough to eat. As the struggle and the search for food continues polar bears are hanging on for survival. Polar bears are on their way to extinction. If we don't act now, most will die in our children's lifetime. But you can change that. Call now and join the Wildlife Rescue Team. For just $16 a month you'll be part of the most ambitious effort to save wildlife and wild places the world has ever seen.... If we don't act now, it could be too late for the polar bear.
It is a fundraising appeal for the World Wildlife Fund (WWF), one of the wealthiest environmentalist groups on the planet. The implied message is that the mother bear and cub in the film have been caught by the camera crew in their last desperate gasps, victims of man-made global warming. We are supposed to believe from the images we see, based upon Wyle's narration, that they are weak and starving and soon will be joining the other members of their rapidly dying species.
However, there are several big problems with this picture and message. First of all, there is no evidence provided in the commercial or by WWF in its literature or on its website that this particular polar bear and her cub are weak, starving, or in any distress whatsoever. For all we can tell they are healthy and happy, floating on their iceberg as polar bears do and have done since they've been around on this planet. It is only the narration and the music that suggest otherwise. But, more importantly, the main message of the commercial is a ... big lie. No sense in mincing words. Completely contrary to the WWF's maudlin claims that the cuddly predators are on "their way to extinction," polar bear populations have been exploding. The number of polar bears in the world is four to five times greater than it was 50 years ago, increasing from around 5,000 to an estimated 25,000.
Canadian biologist Dr. Mitchell Taylor, one of the foremost authorities on polar bears, says: "We're seeing an increase in bears that's really unprecedented, and in places where we're seeing a decrease in the population it's from hunting, not from climate change." Dr. Taylor is a real scientist who actually goes out into the field and tracks, observes, tags, and counts polar bears and other arctic mammals. He has been doing this for over two decades, unlike the computer modelers who are making their dire predictions based on their own theoretical climate scenarios.

Abortion safer than giving birth: study | Reuters
Loony Eugenesist Agenda!
Abortion safer than giving birth: study | Reuters: - Enviado mediante la barra Google
(Reuters Health) - Getting a legal abortion is much safer than giving birth, suggests a new U.S. study published Monday.
Researchers found that women were about 14 times more likely to die during or after giving birth to a live baby than to die from complications of an abortion.
Experts say the findings, though not unexpected, contradict some state laws that suggest abortions are high-risk procedures.
The message is that getting an abortion and giving birth are both safe, said Dr. Anne Davis, who studies obstetrics and gynecology at the Columbia University Medical Center in New York, and wasn't involved in the new study.
"We wouldn't tell people, 'Don't have a baby because it's safer to have an abortion' -- that's ridiculous," she told Reuters Health. "We're trying to help women who are having all reproductive experiences know what to expect."
An induced abortion -- like any other medical procedure -- requires getting informed consent from the woman, said Dr. Bryna Harwood, an ob-gyn from the University of Illinois in Chicago who also didn't participate in the new research.
That means women understand and acknowledge the risks of their different options.
What makes it complicated, Harwood added, is when the law interferes and requires doctors to state information that isn't always balanced or medically sound -- usually exaggerating the risk of abortion.
The researchers on the new study combined government data on live births and pregnancy- and abortion-related deaths with estimates on legal abortions performed in the U.S. from the Guttmacher Institute, which conducts sexual and reproductive health research and education.
Dr. Elizabeth Raymond from Gynuity Health Projects in New York City and Dr. David Grimes of the University of North Carolina School of Medicine, Chapel Hill, found that between 1998 and 2005, one woman died during childbirth for every 11,000 or so babies born.
That compared to one woman of every 167,000 who died from a legal abortion.
The researchers also cited a study from the Centers for Disease Control and Prevention which found that, from 1998 to 2001, the most common complications associated with pregnancy -- including high blood pressure, urinary tract infections and mental health conditions -- happened more often in women who had a live birth than those who got an abortion.
In their report, published in the journal Obstetrics & Gynecology, Raymond and Grimes write that the findings aren't surprising given that women are pregnant for a lot longer when they decide to have a baby and so have more time to develop complications.
Harwood said previous studies have also shown the safety of legal abortions.
Most abortions have typically been done surgically, she told Reuters Health. But since the abortion drug mifepristone was approved for use in the United States in 2000, the number of medically-induced abortions has been on the rise.
Both methods are now considered equally safe, she said, with the main risk -- though very small -- coming from medication- and procedure-related infections.
Depending on the state, however, doctors legally must go over the risks of abortion in language that may be misleading, researchers said, with skewed lists of possible complications. Others require a 24-hour waiting period in between the counseling and the abortion itself.
Harwood said that laws regarding what's said between the doctor and a woman seeking an abortion often hamper doctors' attempts to inform patients in a balanced way.
"It is certainly an impediment to have the state dictate my informed consent process beyond the usual," Harwood told Reuters Health.
"Abortion care and pregnancy care should not really be any different than consenting people for any other procedure."
Davis agreed that state-mandated discussions have no place in abortion counseling. She said she was glad to see the new report, which helps dispel "misinformation" and "lies" about abortion risks included in some state laws -- such as the idea that abortion is linked to cancer.
"Women who are having abortions are having a safe, common surgical procedure or taking medication for the same reason," she told Reuters Health
"They should feel confident that the medical care they're having is safe, long-term and short-term."
