Old bubbles back global warming theory


WASHINGTON -- There is more carbon dioxide in the atmosphere today than at any point during the last 650,000 years, says a new study that let scientists peer back in time at greenhouse gases that can help fuel global warming.

By analyzing tiny air bubbles preserved in Antarctic ice for millennia, a team of European researchers shows how people are dramatically influencing the buildup of these gases.

The research promises to spur "dramatically improved understanding" of climate change, said geosciences specialist Edward Brook of Oregon State University.

The study, by the European Project for Ice Coring in Antarctica, will be published today in the journal Science.

Scientists now directly measure levels of carbon dioxide and other greenhouse gases, which accumulate in the atmosphere as a result of fuel-burning and other processes. Those gases help trap solar heat, like the greenhouses for which they are named, resulting in a gradual warming of the planet.

Those measurements are disturbing:

# The levels of carbon dioxide have climbed from 280 parts per million two centuries ago to 380 p.p.m. today.

# The Earth's average temperature, meanwhile, increased by about 1 degree Fahrenheit in recent decades, a relatively rapid rise.

Many climate specialists warn that continued warming could have severe impacts, such as rising sea levels and changing rainfall patterns.

Skeptics sometimes dismiss the rise in greenhouse gases as part of a naturally fluctuating cycle. The new study provides ever-more definitive evidence countering that view.

Deep Antarctic ice encases tiny air bubbles formed when snowflakes fell over hundreds of thousands of years.

Extracting the air allows a direct measurement of the atmosphere at past points in time, to find the naturally fluctuating range.

A previous ice-core sample had traced greenhouse gases back about 440,000 years. This new sample, from East Antarctica, goes 210,000 years further back in time.

Today's still rising level of carbon dioxide already is 27% higher than its peak during all those millennia, said lead researcher Thomas Stocker of the University of Bern in Switzerland."We are out of that natural range today," he said.

Moreover, that rise is occurring at a speed that "is over a factor of a hundred faster than anything we are seeing in the natural cycles," Stocker added. "It puts the present changes in context."

The team found similar results for methane, another greenhouse gas.

Researchers also compared the gas levels with the Antarctic temperature over that time period, covering eight cycles of alternating glacial or ice ages and warm periods.

They found a stable pattern: Lower levels of gases during cold periods and higher levels during warm periods.

The bottom line: "There's no natural condition that we know about in a really long time where the greenhouse gas levels were anywhere near what they are now. And these studies tell us that there's a strong relationship between temperature and greenhouse gases," said Oregon State's Brook.

Eerst Best, nu dit;

Actor Pat Morita, whose portrayal of the wise and dry-witted Mr. Miyagi in "The Karate Kid" earned him an Oscar nomination, has died. He was 73.

Morita died Thursday at his home in Las Vegas of natural causes, said his wife of 12 years, Evelyn. She said in a statement that her husband, who first rose to fame with a role on "Happy Days," had "dedicated his entire life to acting and comedy."

In 1984, he appeared in the role that would define his career and spawn countless affectionate imitations. As Kesuke Miyagi, the mentor to Ralph Macchio's "Daniel-san," he taught karate while trying to catch flies with chopsticks and offering such advice as "wax on, wax off" to guide Daniel through chores to improve his skills.

Morita said in a 1986 interview with The Associated Press he was billed as Noriyuki "Pat" Morita in the film because producer Jerry Weintraub wanted him to sound more ethnic. He said he used the billing because it was "the only name my parents gave me."

He lost the 1984 best supporting actor award to Haing S. Ngor, who appeared in "The Killing Fields."

For years, Morita played small and sometimes demeaning roles in such films as "Thoroughly Modern Millie" and TV series such as "The Odd Couple" and "Green Acres." His first breakthrough came with "Happy Days," and he followed with his own brief series, "Mr. T and Tina."

"The Karate Kid," led to three sequels, the last of which, 1994's "The Next Karate Kid," paired him with a young Hilary Swank.

Morita was prolific outside of the "Karate Kid" series as well, appearing in "Honeymoon in Vegas," "Spy Hard," "Even Cowgirls Get the Blues" and "The Center of the World." He also provided the voice for a character in the Disney movie "Mulan" in 1998.

Born in northern California on June 28, 1932, the son of migrant fruit pickers, Morita spent most of his early years in the hospital with spinal tuberculosis. He later recovered only to be sent to a Japanese-American internment camp in Arizona during World War II.

"One day I was an invalid," he recalled in a 1989 AP interview. "The next day I was public enemy No. 1 being escorted to an internment camp by an FBI agent wearing a piece."

After the war, Morita's family tried to repair their finances by operating a Sacramento restaurant. It was there that Morita first tried his comedy on patrons.

Because prospects for a Japanese-American standup comic seemed poor, Morita found steady work in computers at Aerojet General. But at age 30 he entered show business full time.

"Only in America could you get away with the kind of comedy I did," he commented. "If I tried it in Japan before the war, it would have been considered blasphemy, and I would have ended in leg irons. "

Morita was to be buried at Palm Green Valley Mortuary and Cemetery.

He is survived by his wife and three daughters from a previous marriage
