Banning Dirty Cars From City Centres in Germany

From the business section of the Toronto Star, Wednesday, January 2, 2008, page B4, an article about Germany's plan for taking car of air pollution and dirty cars:

GERMANY BANS AIR-FOULING VEHICLES

Berlin - Three German cities, including the capital Berlin, began implementing a new air pollution system yesterday that bans the dirtiest vehicles from their centres.

Drivers in Berlin, Cologne and Hanover are now required to display a coloured badge showing the level of pollution cuased by their vehicle, with a scale of red, yellow and green.

Some vehicles, notably an estimated 1.7 million old diesel cars and vans, will not qualify for even the most polluting red badges and will be prohibited in central areas.

Drivers without a badge who are caught in the city centre will face a 40 euro, or $58 (Canadian), fine and will be docked a point on their driving licence.

The system is to be extended to about 20 German cities this year, including Stuttgart and Munich.

It applies to all vehicles, including those registered outside Germany, but some officials have indicated that foreign cars will be treated with leniency.

In Berlin, city authorities have decided not to punish errant drivers until the end of January.

Canada's Environmentally Dreadful Oil Sands

From the October 8, 2007, National section of Maclean's, an article about the toxic outcome for Alberta of the oil sands. I have always thought that Prime Minister Stephen Harper's reticence to cap emissions stems from his protectionism over the development of the oil sands in the province he is from. Apart from that, getting oil from the oil sands is a dirty business and will further ruin additional areas of that province.

Doomsday
Alberta Stands Accused

A huge fight between East and West - over the oil sands - is just starting

By Nicholas Kohler


Left unfettered, Alberta's energy sector will, by the end of this century, transform the southern part of the province into a desert and its north into a treeless, toxic swamp. Driven both by global warming and oil and gas developments, temperatures in Alberta will soar by as much as eight degrees. The Athabasca River will slow to a trickle, parching the remainder of the province's forests and encouraging them to burst into flame, generating vast quantities of CO2. "They're going to be the architects of their own destruction," says journalist William Marsden, whose new book outlines the environmental threats posed by Alberta's energy industry.

Even now, fish pulled from the Athabasca downstream of the oil sands taste of gasoline and smell of burning galoshes in the fry pan. The landscape is perforated by more than 300,000 oil and gas wells. Water in some areas to the south can be set alight with a match, likely due to coal-bed methane developments. Doctors administering to Aboriginal communities not far from the oil sands report high rates of thyroid conditions and rare diseases such as cancer of the bile duct. Some from those communities have been employed at the oil sands raking in the carcasses of ducks floating on vast pools of rotten water, the by-product of the sands' oil-extraction methods.

Such are the claims contained in Marsden's upcoming Stupid to the Last Drop: How Alberta is Bringing Environmental Armageddon to Canada (And Doesn't Seem to Care), which presents a scenario almost too frightening to contemplate and suggests Alberta may already be too far gone for redemption - indeed, that it is environmentally doomed. "When you start digging up an area equivalent to the state of Florida, when you start carpet-bombing your province with oil and gas wells, and at the same time, you've got global warming drying up the glaciers and your rivers - you're kind of looking at a doomsday scenario," he says. "It sounds bizarre, but it's an absolute possibility that they could be literally destroying themselves."

Marsden argues Alberta's political leadership has consistently neglected - in an almost willful, pathological way - to curb the destruction wrought by industry. Former premier Ralph Klein for years rejected placing controls on Alberta's energy sector and, according to Marsden, ordered the dismantling of oversight bodies that might have monitored the degradation, the extent of which remains somewhat unclear today as a result. Marsden charges the province with marginalizing scientists who sound warnings on the environment, quoting Rod Love, Klein's long-time chief of staff, dismissing them as "flakes."

The book is bound to enrage Alberta and its energy sector. "Why are Albertans so stupid?" Marsden asks an Alberta scientist at one point in the book. Designed to be provocative, Stupid to the Last Drop will come under intense fire as an exercise in fearmongering and West-bashing by a Montreal journalist. Yet it will be applauded by others who fear that the environment gets short shrift in Alberta. "I think it's useful to have books like that - it scares people, I guess," says David Keith, an expert on carbon capture at the University of Calgary.

Still, the fight Marsden is picking with Alberta may be a harbinger of a more titanic one to come. Alberta has become the country's economic engine - churning out money at the same time it spews huge emissions - and the rest of Canada, whether out of jealousy or genuine concern, may soon demand environmental controls be placed on the province, the country's worst industrial greenhouse gas emitter. Experts, from constitutional scholars to former Alberta premier Peter Lougheed, are predicting a battle, and at the centre of that coming feud is the issue of how far the federal government can go in controlling a resource Alberta owns. It's a fight some fear may tear Canada apart.

Known mainly for his reporting on organized crime in Canada, Marsden has written a polemic on the Alberta environment that looks at first blush to be a departure. Marsden disagrees."Frankly, I think what's going on in Alberta is a crime," he says. "You get these kinds of political factions and gangsters, almost who have literally taken over a province - and are reducing it to catastrophic shape."

The riches generated by Alberta's energy sector are astounding, the stuff of breathless business stories and promises by the likes of Prime Minister Stephen Harper that the province is on the cusp of becoming an 'energy superpower." Earlier this year, Calgary-based EnCanada earned profits of $6.4 billion, a record-breaking sum. The provincial government's last budget showed a surplus of $8.5 billion. So dynamic is Alberta's energy boom that it's become, what with Ontario's struggling manufacturing sector, the real power in the economy. Remove Alberta from the Canadian economy, some say, and the country would now be in recession.

There is no denying, however, that the wealth comes at a huge environmental cost. In a rollicking, wry style Stupid to the last Drop outlines that environmental degradation, as well as the energy industry's appetite for wild schemes. Marsden dredges up, for example, a little-known plot hatched by an American geologist in the 1950s to free oil from the tar sands by detonating a nuclear device beneath an Alberta creek, a plan that came surprisingly close to execution. And yet, Marsden argues, what is going on right now is almost as outrageous.

Consider the millions in cubic metres of water that three oil sands projects - 20 more are in the works or pending approval - extract from the Athabasca river each year. The water, which in heated form is used to melt the bitumen free of the sands, is crucial; between two and six barrels of water are required to produce a single barrel of oil. Oil sands outfits are sucking 215.2 million cubic metres of water a year, twice what's required for the city of Calgary. Extractions form the Athabasca could triple in the next decade.

As a result of both global warming, which is melting the mountain glaciers that nourish Alberta's waterways, and oil sands extractions, flow in the Athabasca has been reduced by 30 per cent since 9170. By 2020, the oil sands could use as much as half the river's flow in winter, a time when it is at its lowest ebb and fish populations are most stressed. At such levels, says the Pembina Institute's Chris Severson-Baker, "You run the risk of killing the ecosystem." More, Marsden cites scientific research that suggests the 20th century was unusually kind to Alberta in water terms - a desert in its south is a real possibility, he says and warns that industry may be taking advantage of a natural anomaly.

Alberta's oil sands operations also struggle with the problem of what to do with the water once it's been used. Only eight per cent can be made sufficiently clean to go back to the Athabasca. The rest stagnates in huge ponds. "Birds that land on them never take off," David Schindler, an ecologist at the University of Alberta, told Maclean's. Oil sands operators now float buoys in the ponds equipped with hard-hat-wearing scarecrows and propane cannons, whose booming sounds are designed to prevent the water fowl from landing.

Consumption of natural gas, another critical oil sands ingredient, also boggles the mind. By the end of 2005, the industry's daily consumption could heat 3.2 million homes for a day. Marsden notes that present consumption could triple in the oil sands by 2015. Environmentalists have long decried the absurdity of wasting such huge quantities of reasonably clean energy to extract dirtier oil.

Then there's the question of greenhouse gas emissions. The Sierra Club of Canada says oil sands operations spewed 23.3 megatonnes of them in 2000 - about three per cent of Canada's total emissions. Those emissions are predicted to rise between 57 and 97 megatonnes by 2015, making the oil sands Canada's largest single contributor to global warming. The University of Calgary's Keith says the province is responsible for roughly 36 per cent of Canada's CO2 emissions, though most originate in the electrical power industry (the most significant emitters of any industry countrywide). Alberta, Keith points out is "only 11 per cent of the population - it's pretty asymmetric."

The projects are at the same time decimating Albert'a northern boreal forest, which forms an umbrella above a vast, metres-thick deposit of peat, a carbon sink that begins bleeding CO2 into the atmosphere upon excavation. "The boreal forest per unit area actually contains more carbon than the Amazon does," Schindler says. Adds Severson-Baker: "The public has been really focused on the critical role of the tropical rainforest, but the boreal forest plays a similar role" in regulating the earth's climate. The remainder of the boreal forest will soon become a tinderbox of forest fire activity due to a global warming-related pine beetle infestation and an increasingly dry Alberta, Marsden says. The Canadian Forest Service says global-warming models show the area burned by forest fires will double over the next century. High forest fire years already spew emissions equal to 90 per cent of industrial emissions, says Schindler.

It's a startling litany of environmental abuse. but some in Alberta point out that the province has already begun meeting these challenges by bringing in green legislation earlier this year more stringent than federal law. Others believe Marsden's Armageddon won't happen because industry will become cleaner through innovation. "We have a history of meeting those challenges," says Calgary-based Annette Hester, of the Centre for International Governance Innovation. "If it wasn't for meeting those challenges, we would never have an oil sands development in the first place." Oil sands outfits are required by the province to plan for land restoration. And cleaner and more efficient practices - carbon sequestration that buries CO2 or nuclear power as a replacement for natural gas - are in the offing.

Nor does Keith believe doomsday scenarios like those presented by Marsden. Though effects like an eight-degree rise in temperature - one potential outcome included in the book - are possible, "that prediction is contingent on people's choices," says Keith. "My actual prediction is, we won't get close to that." He adds: "Do we have serious environmental problems? Of course. is it true that eventually we will have to close down the entire industry here - the entire industry of producing oil for putting in cars - because of environmental concerns? At some level yeah. Is there going to be a desert? No."

But Marsden believes the future he describes should persuade Alberta to halt further oil sands developments. "I think that you have to put a moratorium on any further growth in the oil sands until that province really figures out where it wants to go," he says. "Then the people of the province - and the people of Canada, too because these are vital resources for all of Canada - can decide how they want to proceed on this." Although such a suggestion may be blasphemous to some - particularly in Alberta - no less a figure than former premier Peter Lougheed has called for a slowdown, in part to study how the oil sands developments are effecting the environment.

Marsden has another point to make. Driving the breakneck pace of Alberta's oil boom, he says, is Canada's commitments to the U.S. under the North America Free Trade Agreement, which he says promises the U.S. an inordinate amount of our oil. Marsden, in effect, argues Canada has sold its soul. "We have ourselves in a corner over NAFTA," says Marsden, "because we've surrendered soverignty over our energy." Stupid to the Last Drop has Lougheed, who helped negotiate NAFTA, predicting that the U.S. will manhandle Canada fiercely should China or India, say, make grabs for a share of the sands. Paraphrasing Lougheed, he writes: Alberta under Ralph Klein...essentially surrendered its control over its resources to the free market, and the Americans have walked in and taken control."

Now Alberta's resource-development surge has put it on a collision course with central Canada's devotion to Kyoto. Lougheed, who predicted this clash of interests in a speech last month in Calgary, warned that Canada's very national fabric could be threatened when Alberta's desire to exploit its resources conflicts with any renewed federal government push to regulate them.

Climate Change Affects Children More

This article about the adverse affects global warming will have on children is from the Stop Global Warming website, http://www.stopglobalwarming.org/sgw_read.asp?id=12391410292007:

Global warming may hit kids harder, pediatrics group says

by: Marilyn Elias 29 October 2007

Global warming is likely to disproportionately harm the health of children, and politicians should launch "aggressive policies" to curb climate change, the American Academy of Pediatrics said today.

In the first major report about the unique effects of global warming on kids, U.S. pediatricians also were advised to "educate" elected officials about the coming dangers.

There's evidence that children are likely to suffer more than adults from climate change, says the report's lead author, Katherine Shea, a pediatrician and adjunct public health professor at the University of North Carolina-Chapel Hill.

"We already have change, and certain bad things are going to happen no matter what we do," Shea says. "But we can prevent things from getting even worse. We don't have the luxury of waiting."

More greenhouse gases and a warming Earth will leave children particularly vulnerable in several ways, the report says:

•Air pollution does more damage to children's lungs, causing asthma and respiratory ailments, because their lungs are still developing, they breathe at a higher rate than adults and are outdoors more.

•Waterborne infections, such as diarrhea and other gastrointestinal problems, hit children especially hard. These infections rise sharply with more rain, which is expected as the climate warms.

•As mosquitoes are able to move to higher ground, the malaria zone is expanding. Kids are especially vulnerable; 75% of malaria deaths occur in children younger than 5.

The report briefly mentions that mass migrations are expected as regions become uninhabitable. "Children fare very poorly in these major population shifts," says Irwin Redlener, director of the National Center for Disaster Preparedness at Columbia University and president of the Children's Health Fund. "They're more fragile medically and nutritionally," says Redlener, who wasn't involved with the report. "They're less resilient, less likely to survive."

No matter what the risks, the pediatrics academy shouldn't be sending its members out to lobby, argues Janice Crouse, director of a think tank affiliated with Concerned Women for America, a conservative public policy group. "Let them issue a scientific report, and people can judge whether it has validity. For a scientific group to use children as a means of advancing a political agenda is beyond the pale," she says.

Julie Gerberding, director of the federal Centers for Disease Control and Prevention, briefed a Senate committee on the health risks of global warming last week. She mentioned increasing asthma, malaria and waterborne diseases but not children's vulnerability.

The Associated Press reported that Gerberding's speech was "eviscerated" by the White House, but CDC spokesman Tom Skinner denied it, adding that Gerberding said everything she wanted to say without constraint.

"This is not a political issue, it's a public health issue," Shea says. "If we know the health of children and future children is threatened, we have an obligation to act."
