Creationism dismissed as 'a kind of paganism' by Vatican's astronomer
BELIEVING that God created the universe in six days is a form of superstitious paganism, the Vatican astronomer Guy Consolmagno claimed yesterday.
Brother Consolmagno, who works in a Vatican observatory in Arizona and as curator of the Vatican meteorite collection in Italy, said a "destructive myth" had developed in modern society that religion and science were competing ideologies.
He described creationism, whose supporters want it taught in schools alongside evolution, as a "kind of paganism" because it harked back to the days of "nature gods" who were responsible for natural events.
Brother Consolmagno argued that the Christian God was a supernatural one, a belief that had led the clergy in the past to become involved in science to seek natural reasons for phenomena such as thunder and lightning, which had been previously attributed to vengeful gods. "Knowledge is dangerous, but so is ignorance. That's why science and religion need to talk to each other," he said.
"Religion needs science to keep it away from superstition and keep it close to reality, to protect it from creationism, which at the end of the day is a kind of paganism - it's turning God into a nature god. And science needs religion in order to have a conscience, to know that, just because something is possible, it may not be a good thing to do."
Brother Consolmagno, who was due to give a speech at the Glasgow Science Centre last night, entitled "Why the Pope has an Astronomer", said the idea of papal infallibility had been a "PR disaster". What it actually meant was that, on matters of faith, followers should accept "somebody has got to be the boss, the final authority".
"It's not like he has a magic power, that God whispers the truth in his ear," he said.

Bush approval rating hits new low
Updated 5/8/2006 1:42 PM ET
By Susan Page, USA TODAY
WASHINGTON — President Bush's approval rating has slumped to 31% in a new USA TODAY/Gallup Poll, the lowest of his presidency and a warning sign for Republicans in the November elections.
The survey of 1,013 adults, taken Friday through Sunday, shows Bush's standing down by 3 percentage points in a single week. His disapproval rating also reached a record: 65%. The margin of error is +/- 3 percentage points.
"It is a challenging political environment," acknowledges Tracey Schmitt, a spokeswoman for the Republican National Committee, "but we are confident that ultimately voters in November will recognize that a Democrat Congress would simply not be equipped to ensure either economic or national security for our nation."
Bush's fall is being fueled by erosion among support from conservatives and Republicans. In the poll, 52% of conservatives and 68% of Republicans approved of the job he is doing. Both are record lows among those groups.
Moderates gave him an approval rating of 28%, liberals of 7%.
"You hear people say he has a hard core that will never desert him, and that has been the case for most of the administration," says Charles Franklin, a political scientist at the University of Wisconsin who studies presidential approval ratings. "But for the last few months, we started to see that hard core seriously erode in support."
Only four presidents have scored lower approval ratings since the Gallup Poll began regularly measuring it in the mid-1940s: Harry Truman, Richard Nixon, Jimmy Carter and the first George Bush. When Nixon, Carter and the elder Bush sank below 35%, they never again registered above 40%.
Truman twice sank into the low 30s and then rose into the 60s, but the third time his rating fell, it stayed below 40% as well.
"Historically it's been pretty devastating to presidents at this level," Franklin says. Even Republican members of Congress are "now so worried about their electoral fortunes in November that he has less leverage with them than he normally would with his own party controlling Congress."
So, about that "mandate", George...

Climate Change Drives Disease To New Territory
Viruses Moving North to Areas Unprepared for Them, Experts Say

TORONTO -- Valere Rommelaere, 82, survived the D-Day invasion in Normandy, but not a mosquito bite. Six decades after the war, the hardy Saskatchewan farmer was bitten by a bug carrying a disease that has spread from the equator to Canada as temperatures have risen. Within weeks, he died from West Nile virus.
Global warming -- with an accompanying rise in floods and droughts -- is fueling the spread of epidemics in areas unprepared for the diseases, say many health experts worldwide. Mosquitoes, ticks, mice and other carriers are surviving warmer winters and expanding their range, bringing health threats with them.
Malaria is climbing the mountains to reach populations in higher elevations in Africa and Latin America. Cholera is growing in warmer seas. Dengue fever and Lyme disease are moving north. West Nile virus, never seen on this continent until seven years ago, has infected more than 21,000 people in the United States and Canada and killed more than 800.
The World Health Organization has identified more than 30 new or resurgent diseases in the last three decades, the sort of explosion some experts say has not happened since the Industrial Revolution brought masses of people together in cities.
"We didn't even know West Nile virus existed here," said Maria Bujak, 63, of Toronto. Her husband, Andrew, contracted the disease in their garden in 2002. He never fully recovered, she said, and died two years later.
"Tropical diseases are here to stay in Canada. We needed our government to wake up and tell us that," said Douglas Elliott, a Toronto lawyer who has brought suit against the Ontario government on behalf of about 40 victims, contending that the government did not do enough to inform the public about the dangers of West Nile.
Scientists have warned for more than a decade that climate change would broaden the range of many diseases. But the warnings were couched in the future, and qualified. The spread of disease is affected by many uncertainties, including unforeseen resistance to antibiotics, failures of public health systems, population movement and yearly climate swings. For that reason, some scientists have been cautious about the link between disease and global warming.
But Paul Epstein, a physician who worked in Africa and is now on the faculty of Harvard Medical School, said that, if anything, scientists weren't worried enough about the problem.
"Things we projected to occur in 2080 are happening in 2006. What we didn't get is how fast and how big it is, and the degree to which the biological systems would respond," Epstein said in an interview in Boston. "Our mistake was in underestimation."
The incremental boost already detected in the Earth's temperature, for example, has expanded the range and activities of disease carriers.
"Insects are exquisitely sensitive to temperature changes," a report prepared by Epstein and others at Harvard's Center for Health and the Global Environment noted in November.
The clearest case for that, according to the report's authors, is in cold areas. The higher elevations of Africa, the Andes mountains in South America and the Alps in Europe are warming at a faster pace than lowlands. As ice caps and glaciers melt, forests inch higher on the mountains, and insects carry diseases from warmer lowlands farther up the slopes.
A WHO report in 2000 found that warming had caused malaria to spread from three districts in western Kenya to 13 and led to epidemics of the disease in Rwanda and Tanzania. In Sweden, cases of tick-borne encephalitis have risen in direct correlation to warmer winters. Asian tiger mosquitoes, the type that carry dengue fever, have been reported recently as far north as the Netherlands.
As the seas warm, other breeders thrive. Cholera, a waterborne disease, emerged in South America in 1991 for the first time in the 20th century. Abetted by poverty and poor public health, it swept from Peru across the continent and into Mexico, killing more than 10,000 people.
Diseases are also expanding in a surprisingly complex dance with their environment, taking advantage of the swings from deluge to drought made more frequent by global warming, Epstein said.
A common house mosquito, called the Culex pipiens , for example, unexpectedly thrives in drought. It lives in drainpipes and sewer puddles. During long dry spells, the stagnant pools teem with protein and attract thirsty birds on which mosquitoes feed. Meanwhile, droughts reduce the populations of dragonflies, lacewings and frogs that eat the mosquitoes.
The Culex pipiens is a favored carrier of a disease first identified in a feverish woman in the West Nile district of Uganda in 1937. The disease was found again in Israel in the 1950s, and in Romania in 1996. Each outbreak followed an unusual dry, hot spell, typical of adverse weather becoming more frequent as a result of climate change, concluded researchers at the University of Haifa in Israel.
In 1999, the virus landed in New York, probably at LaGuardia Airport. Disease sleuths speculate that it was lurking in a mosquito stowaway on a plane, or in the bloodstream of someone already infected. That summer also brought unusually hot, arid weather to New York, perfect for the Culex pipiens.
Before the year was over, 62 people had been infected and seven had died, the first of them elderly. The next two years were more temperate, but when another hot, dry summer hit in 2002, the disease exploded across the United States and into Canada.
Susan Harrison, then 45, prepared a Labor Day barbecue that year with her husband and two daughters on the deck of their small house in Toronto. She was bitten by a mosquito, but shrugged it off.
In a few days, she felt a shooting pain in her legs. Within two weeks, she could not get out of bed. Her husband, Phil, rushed her to the hospital, where she was put on a respirator and spent three months in intensive care. She now maneuvers around her narrow house in a wheelchair, her legs and right arm paralyzed by West Nile virus.
Tears welled in her eyes as he spoke of her daughters, Allison, 10, and Tara, 13. "I used to do things with them, take them places," she said. Her husband, a waiter, struggles to fill the role of two parents.
West Nile virus killed 304 people in North America in 2002 and 276 the next year. The toll dropped to about 100 in 2004, probably because of cooler weather and mosquito-control measures.
West Nile has killed 22 people in Maryland, Virginia and the District since 2001.
Despite the recent drop in the death toll, birds and horses in hot western regions are still being devastated, and the disease has likely not finished with humans.
"West Nile virus hasn't gone away. People still need to be aware that it's there," said Edward B. Hayes, a medical epidemiologist with the Centers for Disease Control and Prevention in Fort Collins, Colo. "Whether we have large-scale epidemics is anyone's guess."
Climate change already is claiming more than 150,000 lives each year, with causes ranging from heat waves to respiratory illness, WHO concluded last year.
Some scientists see global warming as a natural cycle that will soon reverse itself, but for many governments, the handwriting is increasingly clear. Britain's environment minister warned last year that malaria might reach that country. South Africa's environmental affairs minister said last year that the country could face a fourfold increase in malaria by 2020. The Canadian government now attributes the boost in West Nile virus to climate change, and last year warned that the country might eventually experience dengue fever, yellow fever and malaria.
"One of the problems we have in North America is coming to grips with the fact that epidemics are still a problem," said Elliott, the lawyer. "Canadians, prior to West Nile virus, just considered mosquitoes to be annoying. We had never thought of mosquitoes as being disease carriers."
