Tamarama

Waves reached heights of up to eight metres, according to weather experts - or a mere four metres, according to the less-macho reckoning of surfers.

Several beaches were closed, including Bronte, Maroubra, Newport and Palm Beach, while Bondi lifeguards stopped swimmers from going beyond shallow water. Water police and rescue helicopters were called to Manly about 6.30pm after two men on surf skis were hit by a giant wave.

One of the men washed onto Shelly Beach, south of Manly.

Water police found the other surfer about an hour later a kilometre off Queenscliff to the north.
Former pro-surfer Matt Grainger, who owns Manly Surf School, spent the day surfing off Long Reef and Queenscliff, but warned that only advanced surfers should brave the treacherous conditions. At Bronte, even the baths were closed as huge waves lashed the southern end of the beach.

High winds from the weather system formerly known as Tropical Cyclone Wati started the huge swell 1000 kilometres offshore in the Tasman Sea.

Scientists Find Skull of Human Ancestor


ADDIS ABABA, Ethiopia
Mar 25, 2006 (AP)

Scientists in northeastern Ethiopia said Saturday that they have discovered the skull of a small human ancestor that could be a missing link between the extinct Homo erectus and modern man.

The hominid cranium found in two pieces and believed to be between 500,000 and 250,000 years old "comes from a very significant period and is very close to the appearance of the anatomically modern human," said Sileshi Semaw, director of the Gona Paleoanthropological Research Project in Ethiopia.

Archaeologists found the early human cranium five weeks ago at Gawis in Ethiopia's northeastern Afar region, Sileshi said.

Several stone tools and fossilized animals including two types of pigs, zebras, elephants, antelopes, cats, and rodents were also found at the site.

Sileshi, an Ethiopian paleoanthropologist based at Indiana University, said most fossil hominids are found in pieces but the near-complete skull a rare find provided a wealth of information.
"The Gawis cranium provides us with the opportunity to look at the face of one of our ancestors," the archaeology project said in a statement.

Homo erectus, which many believe was an ancestor of modern Homo sapiens, is thought to have died out 100,000 to 200,000 years ago.

The cranium dates to a time about which little is known the transition from African Homo erectus to modern humans. The fossil record from Africa for this period is sparse and most of the specimens poorly dated, project archaeologists said.

The face and cranium of the fossil are recognizably different from those of modern humans, but bear unmistakable anatomical evidence that it belongs to the modern human's ancestry, Sileshi said.

"A good fossil provides anatomical evidence that allows us to refine our understanding of evolution. A great fossil forces us to re-examine our views of human origins. I believe the Gawis cranium is a great fossil," said Scott Simpson, a project paleontologist from Case Western Reserve University School of Medicine at Cleveland, Ohio.

Scientists conducting surveys in the Gawis River drainage basin found the skull in a small gully, the project statement said.

"This is really exciting because it joins a limited number of fossils which appear to be evolutionary between Homo erectus and our own species Homo sapiens," said Eric Delson, a paleoanthropologist at Lehman College of the City University of New York, who was not involved in the discovery but has followed the project.

Homo erectus left Africa about 2 million years ago and spread across Asia from Georgia in the Caucasus to China and Indonesia. It first appeared in Africa between 1 million and 2 million years ago.

Between 1 million and perhaps 200,000 years ago, one or more species existed in Africa that gave rise to the earliest members of our own species Homo sapiens between 150,000 and 200,000 years ago.

Delson said the fossil found in Ethiopia "might represent a population broadly ancestral to modern humans or it might prove to be one of several side branches which died out without living descendants."

Paris burns


IT WAS just the scene the French Government had been dreading: burning cars seven blocks from the Eiffel Tower, shop windows smashed along one of the capital's smartest streets, and columns of helmeted riot police advancing near a prominent tourist venue.

Antoil Ethuin, 48, stood outside the shattered windows of his Bike'n'Roll rental shop on Thursday, stunned by the destruction of the worst violence in two weeks of student protests in Paris and other French cities.

"My country is broken," said Mr Ethuin, gazing at the smouldering wrecks a few metres away and the carpet of glass shards, broken dishes and computer parts covering the footpath in the heart of one of the city's most affluent suburbs.

"I never imagined I would ever see this in Paris."

The unrest intensified a political crisis threatening to unravel the Government much the way previous French governments have been felled by strikes and street protests when they attempted even modest reforms of the costly welfare state.

The Prime Minister, Dominique de Villepin, hastily arranged an emergency meeting with the most influential unions to defuse the crisis.

On Thursday, as a crowd of 140,000 were about to end their march in the park adjoining the gold-domed Hotel des Invalides, near Napoleon's tomb, gangs of hooded and masked youths darted out of side streets, setting cars ablaze, flipping others upside down, breaking shop windows and hurling rocks at police and firefighters.

Riot police broke up the groups with teargas as acrid black smoke filled narrow streets and billowed above the skyline.

Police said 60 people were injured in the clashes, including 27 police officers. Officials said 141 people were arrested.

Mr Villepin had attempted to capitalise on the political misfortunes of his rival, the Interior Minister, Nicolas Sarkozy, by advocating a law he said was intended to give companies greater incentive to hire young people. The law would allow employers to fire workers aged under 26 without reason during their first two years on the job.

University students, other young people and unions say the law discriminates against the young by denying them the job security that older workers have.

On Thursday newspapers began reporting leaks from anonymous government officials that President Jacques Chirac was threatening to fire Mr Villepin if he did not resolve the escalating crisis quickly.

Melting ice sheets could spur oceans' rise - study


Miami would be a memory, Bangkok a soggy shadow of its former self and the Maldive Islands would vanish if melting polar ice keeps fuelling a faster-than-expected rise in sea levels, according to scientists.

In an issue of the journal Science focusing on global warming, climate scientist Jonathan Overpeck of the University of Arizona reported that if global trends continue, Earth could ultimately experience sea levels six meters higher than they are now.

By the end of this century, Earth would be at least 2.3C warmer than now, or about as hot as it was nearly 130,000 years ago.

Back then, significant portions of the Greenland and Antarctic ice sheets melted, pushing the global sea levels to about six meters higher than current levels.

A similarly dramatic, and in some cases catastrophic, rise in ocean levels could happen by the year 2500, Overpeck said in a telephone interview, but he noted it could come sooner.
"We know when the sea level was that high in the past, and we know how much warming is necessary to get that amount of sea level rise from both Greenland and Antarctica," Overpeck said.

The Earth will get that hot sometime early in the second half of this century, he said, and once it does, the big ice sheets will start melting "in a more dramatic manner" than they currently are.
A conservative estimate would call for sea level rises of one metre per century, he said.
He cautioned, however, that this estimate assumes the Earth will get only as hot as it did 130,000 years ago when the ice sheets melted.

"If we decide to keep on the track we're on now and just keep on warming, because of greenhouse gas pollution, then we could easily cook those ice sheets more rapidly," Overpeck said.

The earlier ice melt was concentrated in the Northern Hemisphere in the summer months, and was due largely to changes in Earth's orbit, he said.

"The climate warming we're in now is global and it's year-round and it's due to human influences on the climate system," he said. "That will be more damaging to the ice sheets than the that warming we had 130,000 years ago."

The ice sheets are already melting, accelerated by relatively warm water that eats away at them, said NASA glacier expert Bob Bindschadler.

"It's not really a debate any more about whether sea level is rising or not. I think the debate has shifted to, how rapidly is sea level rising," Bindschadler said in a telephone briefing.
Overpeck's Web site -- http://www.geo.arizona.edu/dgesl/ -- offers dynamic maps of the projected results of the rise in sea levels.

Plant, animal extinctions speeding up


By David Adam
March 22, 2006

HUMANS have provoked the worst series of extinctions since the dinosaurs were wiped out 65 million years ago, says a United Nations report that calls for unprecedented worldwide efforts to address the slide.

The report paints a grim picture of life on earth, with declining numbers of plants and animals, and warns that the current extinction rate is up to 1000 times faster than in the past. About 844 animals and plants are known to have disappeared in the past 500 years.

Released on Monday to mark the start of a UN environment program meeting in Curitiba, Brazil, the report says: "In effect, we are currently responsible for the sixth major extinction event in the history of earth."

A rising human population of 6.5 billion is wrecking the environment for thousands of other species, it adds, and undermining efforts agreed at a 2002 UN summit in Johannesburg to slow the rate of decline by 2010. The global demand for biological resources now exceeds the planet's capacity to renew them by 20 per cent.

The report, Global Biodiversity Outlook 2 from the UN Convention on Biological Diversity, says: "The direct causes of biodiversity loss - habitat change, over-exploitation, the introduction of invasive alien species, nutrient loading and climate change - show no sign of abating."

Stop the War


Thousands of demonstrators across the world have denounced the US-led war in Iraq in another day of protests marking the invasion's third anniversary.

Father wants to divorce his 7month old daughter

SEVEN-MONTH-OLD Elizabeth Wells has never been held in her father's arms, and if he has his way she never will be.

In what could be a landmark case in the US, Matt Dubay, a computer programmer, is asking the courts to absolve him of all the responsibilities of fatherhood.

Mr Dubay's lawsuit has the backing of the National Centre for Men, activists who say that equal opportunities have swung too far in favour of women.

For Mr Dubay, 25, news that he was about to become a father was an unwelcome shock. It followed a night spent with a student, Lauren Wells, who he claims told him that she was infertile and using contraception. The apparent contradiction of those remarks did not fully hit Mr Dubay until several weeks later, when Ms Wells, 20, told him she was pregnant.

While the relationship soon foundered, his former girlfriend said she was keeping the child and, when the baby was born last August, she began legal proceedings to ensure that her former boyfriend paid his way in bringing up their daughter.

Faced with a court order for $US500 ($690) a month in child support, Mr Dubay said not paying was his constitutional right.

"I don't believe men have any say … [they are] simply ignored," he said from his home in Saginaw, Michigan. After learning that Ms Wells was pregnant, Mr Dubay said he talked to her about an abortion or having the baby adopted, but she ruled out both. "I painted a very clear picture at that point that I was not ready to be a father," he said. "I was not ready to be a part of the child's life."

His lawsuit, filed in a federal court, says that men who face fatherhood without their consent should be able to opt out of their responsibilities. While it does not seek to force women to have an abortion or give up their babies for adoption, it claims that women have the right to pursue either option if they do not want to bring up a child on their own.

The founder of the National Centre for Men, Mel Feit, said: "Men are routinely forced to give up control, forced to be financially responsible for choices only women are permitted to make, forced to relinquish reproductive choice as the price of intimacy.

"A man must choose to be a father in the same way that a woman chooses to be a mother," Mr Feit said.

Ms Wells said in a statement through her lawyer on Saturday that "my focus is on providing a nurturing home for our baby".

Saying that she was disappointed in Mr Dubay's decision, she added: "I believe that life begins at conception and blossoms. I take responsibility for my acts and will do my best as an adult and mother to protect and provide for our daughter."

Mr Dubay has met his daughter just once, when both attended a clinic for blood tests that proved he was her father. He admitted it was "difficult to look away" when the baby was in the room, but he believes it would disrupt her life if he assumed any other duties of parenthood. "I still, to this point, believe that it isn't right to be part of the child's life. An unwilling parent is not good for a child."

Earth Faces Mass Extinction

By Nassim Khadem, Canberra
March 16, 2006

A LEADING British environmental scientist has urged the Australian Government to switch its focus from nuclear power and clean-coal technologies to renewable energies.

Norman Myers said he had raised the issue with federal Environment Minister Ian Campbell just two days ago.

Professor Myers was speaking yesterday at the National Press Club about the mass extinction of animal and plant species being a greater threat to the world than global warming.

Professor Myers, a visiting fellow of Oxford University, said despite Australia having vast amounts of coal and uranium available to export to countries such as China, it still needed to consider how it would produce energy beyond the fossil-fuel era. "I would suggest to Australia, as I did to the minister, that in anticipation of the end of the fossil fuel era … Australia might want to develop an alternative energy strategy. That is, a clean and renewable source of technology."

Asked whether he agreed with the Australian Government that nuclear power was a possible way to reduce global warming, he said it was not safe and it would take at least 10 years before a nuclear power plant would be operational.

His comments came as Australia confirmed it was close to signing an agreement with China on the sale of uranium. Officials from both nations met in Beijing a fortnight ago for the latest round of negotiations.

Professor Myers, who has been a senior adviser on biodiversity to the United Nations, the World Bank and the White House, said Earth was experiencing the largest mass extinction of species in 65 million years. He said there were about 10 million species and half could be lost if governments did not act quickly.

Professor Myers is renowned for identifying "hot spots" — homes to our most valuable animal and plant species — in grave need of protection. There are 34 hot spots and only five countries have more than one. Australia has two: one in southern Western Australia and the other taking in forests on the east coast.

A UN meeting in Brazil next week will discuss reducing the loss of species by 2010.

Club 793 - Billionaires Only

A billion dollars, says Luisa Kroll, who edits Forbes magazine’s list of the world super-rich, is “just not what it used to be”. Too right! There’s now something horribly common about being a billionaire. Forbes names an incredible 793 of them round the world — 102 more than last year. In London alone there are 23, including the steel magnate Lakshmi Mittal, now the world’s fifth richest person.

At the top of the Billionaires Club, admittedly, there’s still some serious money around. Between them the three richest dudes on the planet — Bill Gates, Warren Buffett (the man always quaintly described as Gates’s “bridge partner") and the Mexican telecom mogul and serial Rodin hoarder Carlos HelĂș — possess more wealth than the world’s 600 million poorest people put together.
