Gasoline Temperature Maps

 
I recently posted about problems with the Alberta oil sands and the impact on carbon emissions and the environment [The Problem with the Alberta Oil Sands].

I noted that Alberta had received lots of money from the oil companies and suggested that the provincial government was well-positioned to take the lead in developing cleaner methods of extracting oil. I specifically said that the province had "plenty of room to manoeuvre."

One commenter noted that the provincial government doesn't have as much money as we think. But that wasn't the entire point. I was also referring to the fact that provincial income taxes are lower in Alberta and the province does not have a sales tax.

I was thinking about gasoline prices as well. Here's a map of current gas prices across Canada from GasBuddy.com. Most of the differences are due to taxes. Notice anything peculiar about Alberta—the province that's being accused of so much pollution? I think there's room to manoeuvre if it's serious about climate change.


Here's the USA map for comparison.



A typical US price is $2 per (US) gallon. The current Canadian dollar is equivalent to about 0.8 US dollars and there are 3.79 litres per US gallon. This means that a typical US gas price of $2.00/gal is equivalent to 53¢(US)/liter or 66¢(CDN)/liter.

A typical price for Canadian gas is about 86¢(CDN)/liter so the USA is selling gasoline for 20% less than Canada. I think this is mostly due to lower taxes.

I don't know what the current price of gasoline is in Europe but I suspect it's much more.


Come Ride an "Atheist" Streetcar on the Streets of Toronto!

 
The Canadian Atheist Bus Campaign is throwing a party on Friday night. Meet for food and drinks at the Centre for Inquiry on Beverly St. then take a one hour ride on a TTC streetcar bearing the atheist ad [Toronto Streetcar Party Tickets Now on Sale!].
A party in the downtown Toronto area on a streetcar and at the Centre for Inquiry building. Ticket holders will receive one ride on a streetcar around various landmarks in the downtown Toronto area and also have a chance to mingle, talk, and party with other atheists, secularists, and humanists at the Centre for Inquiry. Drinks and food will be available for purchase.
This is your chance to meet and thank the organizers who raised the money and got the ads on the buses (and streetcars). Buy a ticket and help support the cause in other Canadian cities.


Free Speech in Ottawa

 
Some of you might recognize these people in spite of their attempts to disguise themselves!1

They are protesting the decision by OC Transpo in Ottawa (Canada) to ban the atheist ads on city buses. Apparently it's okay to run Christian ads but the atheist ad is "too controversial."

The Humanist Association of Ottawa wants you to show up at Ottawa City Hall on Wednesday March 11 when the city council is scheduled to vote on a motion to overrule OC Transpo and allow the ads [Protest the bigots at City Hall]. Several members of council are sympathetic and the first vote last month was a tie. It only takes one more council member to get the ads on the buses.

Atheist Bus Ottawa has put up a petition that you can sign. Do it now!

Playing Chess with Pigeons

 
It's the blogiversary of Troy Britain's blog Playing Chess with Pigeons. Today it is one year old.

Congratulations Troy! Check out today's posting to see the cake [It’s Playing Chess with Pigeons 1st Birthday!]. Look in the right sidebar to see where the title of the blog comes from. It's really clever—I'd love to quote it here but if I do that you might not want to read it in situ and that would be a shame.

Massimo Pigliucci vs Jonathan Wells

 
Greg Laden found this old video of a moderated discussion between Massimo Pigliucci and Jonathan Wells [Massimo Pigliucci v Jonathan Wells on evolution and intelligent design...].

It's actually pretty good. If you don't pay close attention, you might even mistake Jonathan Wells for someone intelligent.




When Atheism Is the Norm

 
The Friendly Atheist has posted an interesting comment on what's it's like to live in Denmark or Sweden [What Happens When Atheism is the Norm Instead of the Exception?].

His comments are based on a recent article in The New York Times that discussed that topic [Scandanavian Nonbelievers, Which Is Not to Say Atheists].
Anyone who has paid attention knows that Denmark and Sweden are among the least religious nations in the world. Polls asking about belief in God, the importance of religion in people’s lives, belief in life after death or church attendance consistently bear this out.

It is also well known that in various rankings of nations by life expectancy, child welfare, literacy, schooling, economic equality, standard of living and competitiveness, Denmark and Sweden stand in the first tier.

Well documented though they may be, these two sets of facts run up against the assumption of many Americans that a society where religion is minimal would be, in Mr. Zuckerman’s words, “rampant with immorality, full of evil and teeming with depravity.”

Which is why he insists at some length that what he and his wife and children experienced was quite the opposite: “a society — a markedly irreligious society — that was, above all, moral, stable, humane and deeply good.”
This is a very important issue. You should read the article by Peter Steinfels and the posting by Hemant Mehta. I often encounter otherwise intelligent people who try to tell me that religion is here to stay—it will never disappear. Those people really need to get out more. We already have societies today where religion, and belief in God, are minority views.

As you might imagine, there won't be too many attempts to teach creationism in Danish and Swedish schools. That's not because their courts are good at keeping religion out of the schools, it's because the hearts and minds of the people have changed. Rationalism is winning over superstition.

It could happen in America. I think it is happening.


The Problem with the Alberta Oil Sands

 

This month's issue of National Geographic has a lengthy article on the Alberta oil sands [The Canadian Oil Boom].
The U.S. imports more oil from Canada than from any other nation, about 19 percent of its total foreign supply, and around half of that now comes from the oil sands. Anything that reduces our dependence on Middle Eastern oil, many Americans would say, is a good thing. But clawing and cooking a barrel of crude from the oil sands emits as much as three times more carbon dioxide than letting one gush from the ground in Saudi Arabia. The oil sands are still a tiny part of the world's carbon problem—they account for less than a tenth of one percent of global CO2 emissions—but to many environmentalists they are the thin end of the wedge, the first step along a path that could lead to other, even dirtier sources of oil: producing it from oil shale or coal. "Oil sands represent a decision point for North America and the world," says Simon Dyer of the Pembina Institute, a moderate and widely respected Canadian environmental group. "Are we going to get serious about alternative energy, or are we going to go down the unconventional-oil track? The fact that we're willing to move four tons of earth for a single barrel really shows that the world is running out of easy oil."
Canadians know there's a problem but politicians are very reluctant to address it. Albertans have been very vocal in playing the victim card in Canadian politics. They have successfully convinced people that the province was hard done by in the past when the evil citizens of Ontario and Quebec tried to deprive them of their right to keep all the oil money for themselves, instead of sharing it with less fortunate Canadians.

Today, any attempt by the Federal government to impose restrictions on Alberta will be viewed as an act of war.

There's an obvious solution. The government of Alberta has amassed a fortune in oil revenues. Even in these tough economic times, it still has plenty of room to manoeuvre.

Wouldn't it be wonderful if the provincial government took steps to reduce green house gas emissions and develop greener ways of extracting oil? Wouldn't it be wonderful if they took the lead in recognizing there's a problem and start to deal with it? There's some evidence that the Alberta government might be headed in that direction [National Geographic oilsands portrayal "fair": environment minister].

Of course they'd have to abandon the whining about Alberta being a victim of the East. In the long run, that may be very hard to do.

United Kingdom Protects Science Budget

 
From NatureNews: Brown pledges to protect science during downturn.
British Prime Minister Gordon Brown said he would not let science "become a victim of the recession" in a speech today at the University of Oxford.

Speaking to an invited audience, Brown said he would defend investment in science by maintaining the ring fence around the science budget, so that it cannot be raided to prop up other areas competing for public funds such as the health service and industry.

He signalled his aim for Britain to move away from an economy "heavily centred" on financial services and towards one focused on science.

....

Responding to Brown's speech, Nick Dusic, director of the Campaign for Science & Engineering in the UK (CaSE), a London-based lobby group says, "The prime minister is absolutely right that now is the time to show the world the UK is the place to do science. Unfortunately he needed to go further today in his commitments because other countries are raising the bar by making science and engineering central to their economic recovery."

Dusic added that just maintaining current spending commitments will mean that Britain loses ground against countries, like the United States, that are giving science a huge boost within their stimulus packages.
Meanwhile, Stephen Harper and the Conservative Party are cutting the budgets of the major granting agencies in Canada.

How stupid is that?

Crime and Punishment

 
True to their ideology, Stephen Harper and the Conservatives have introduced another "get tough on crime" bill. This one increases the jail sentences for gang-related killings.

There's only one problem. It won't work. Everyone with an IQ over 100 knows that you can't stop gang violence by just increasing prison terms for the ones who get caught.

Today's Toronto Star has two articles on the topic. The first one, Tory gang approach too little too late: critics, explains the consensus opinion of leading criminologists.
The punitive response may play well to citizens who fear gun battles erupting on city streets. But that get-tough approach lards the Criminal Code with redundant laws that haven't worked in other countries, says criminologist Irvin Waller.

"This is yet again a debate about penalties when it's very clear from looking south of the border that these penalties do not make a lot of difference to the number of people killed," he said.

"It's not a debate about what will actually stop them from happening."

Waller, a professor at the University of Ottawa, wrote the book Less Law, More Order to educate politicians on prevention and smart policing practices that have worked in other countries.
The second article, Critics say more jail time won't help curb violence, goes into more detail about what the experts are saying.
Criminologists predict tough sentences won't be effective in preventing gun and gang violence

Proposals to slap first-degree murder charges and tougher sentences on gangsters and police assailants will have little practical effect on curbing gang crime and gun violence, criminologists and other critics say.

More front-line officers, more intrusive investigative police powers and more resources for crime prevention are needed, they say.

Ross Hastings, director of the Institute for the Prevention of Crime at the University of Ottawa, joins other criminologists in arguing there is no evidence tougher sentences deter criminals, but the "certainty of being caught" is more likely to do so.

Nonetheless, amid an alarming rise in Vancouver's gang violence, politicians of all stripes rushed yesterday to endorse federal proposals to label gang killings first-degree murder offences, and to stiffen jail terms for drive-by or reckless gang-motivated shootings and assaults on police.

All three federal opposition parties promised to fast-track the measures proposed by the Tories.
I'm disappointed in all four political parties. Most of our MP's have IQ's above 100 and they know the rational response to gang violence. They know that this bill will be completely ineffective.

The only reason for supporting it is to pander to voters who don't understand the problem. There are far too many voters whose knee-jerk reaction in the face of any crime is to call for "justice" by increasing jail time. A majority of those voters probably support the Conservatives so there's nothing to be gained by the opposition parties' lack of fortitude.

Shame on Stephen Harper for his (probable) hypocrisy. Shame on Michael Ingatieff, Jack Layton, and Gilles Duceppe for being even more hypocritical. They should know better.


Darwin Stamps

 
A few days ago I got a letter from the Royal Mail. It was a complete set of Darwin stamps issued by the Royal Mail in the UK to honour Charles Darwin. You can see some of them on the right. They are stunning. Thank-you Ms. Sandwalk for arranging to have them sent.

I also got a postcard from Kate. She mailed it from London on Darwin's birthday. It was addressed to someone called "The Nutty Professor" but for some strange reason it ended up in my mailbox anyway. Thank-you Kate & Mick.

Great Britain, especially London, was the intellectual capital of the world back in Queen Victoria's time. Most of the world's top scientists were there and the number of scientific advances that came out of that environment was truly amazing.

Much of it was due to the wealth of the British Empire (science loves money) but also to the intellectual freedom, individualism, and entrepreneurship that was characteristic of that society. It was the same society that created the industrial revolution and sustained it for one hundred years.1

What's amazing is that not only did Victorian England nurture and support men like Charles Darwin but that today, 150 years later, Great Britain is still proud to celebrate the scientist whose name is most closely associated with evolution.

Matt Nisbet Chooses Sides

 
Carl Zimmer has posted another article on the Geroge Will affair [Unchecked Ice: A Saga in Five Chapters]. Recall that George Will made a number of scientifically inaccurate comments in his Washington Post article last week. He defends himself in another column today.

Carl dissects the issue in order to set the record, straight. Any decent science journalist should be concerned about accuracy and I'm pleased that Carl has made an effort to stand up for the truth. The Washington Post takes the brunt of the blame.
What has kept me hooked on this saga is not George Will’s errors. Errors are as common as grass. Some are made out of ignorance, some carefully constructed to give a misleading impression. What has kept me agog is the way the editors at the Washington Post have actually given their stamp of approval on Will’s columns, even claiming to have fact-checked them and seeing no need for a single correction.
Chris Mooney has also attacked the newspaper for it's lack of integrity [George Will Lies; His Editor Does Nothing].
Many of the column's incorrect factual assertions were challenged, and as Will is revisiting the column due to the response it has garnered, it's inconceivable that he doesn't know that. For God's sake, Will claimed that "according to the U.N. World Meteorological Organization, there has been no recorded global warming for more than a decade." That's false. And Will doesn't even address the issue at all in his latest column.

Meanwhile, the Post's editorial page editor Fred Hiatt has made himself look terrible over all this. He should have held Will to the truth and thereby upheld his paper's standards. Instead he tells CJR this:
"It may well be that he is drawing inferences from data that most scientists reject -- so, you know, fine, I welcome anyone to make that point. But don't make it by suggesting that George Will shouldn't be allowed to make the contrary point. Debate him."
All of this is good. It is highly appropriate that science journalists reestablish their credibility by criticizing amateurs who don't know what they're talking about.

Where is Matt Nisbet in all of this? Here's what Nisbet says in In the Clamor Over George Will, Pundits Win But Public Loses.
The same observation currently applies to the clamor over George Will's recent syndicated column on global warming. As I detail in a cover article at the March/April issue of the journal Environment, Will's column is part of a decade-old message playbook on climate change, effectively (and falsely) framing the problem in terms of lingering scientific uncertainty.

The irony of this latest netroots clamor is that dozens of bloggers are just feeding the George Will beast, sustaining and amplifying attention to his false claims about climate science while providing easy cues to the public that the issue can be readily interpreted through the lens of partisanship and ideology. (Sound familiar? As I wrote at Skeptical Inquirer, the same thing happened in the initial response to Ben Stein's anti-evolution doc Expelled.)

The conflict and heat generated not only focuses more attention on Will's preferred uncertainty interpretations, but it also distracts from the narratives and frames that are actually likely to build broad-based support for action. As I note in the Environment article, these frames include an emphasis on the moral and religious imperative to action along with a focus on the public health and energy innovation dimensions of climate change.
Over the past two years, many of us have been pointing out the conflict between "framing" and scientific accuracy. Now Nisbet makes it perfectly clear. If you criticize the scientific accuracy of an article in the main stream media then you might be hurting the cause.

The implication is that you should let scientific errors go unchallenged because challenging them give them credence. The more insidious implication is that scientific inaccuracy may be okay as long as it advances the cause.

It seems to me that Nisbet's view and Chris Mooney's recent claims are not compatible. I look forward to seeing how Mooney replies to Nisbet. Chris has already tried to distance himself from Nisbet last Spring over the Ben Stein affair [see For Once, Chris Mooney Talks Sense].

Internecine framing wars, what could be more fun than that?


The Atheist Ad Campaign on The Agenda

 
TV Ontario (TVO) has a daily program called The Agenda with Steve Paikin. It's usually very good.

Last week they had a show on the atheist bus campaign featuring Justin Trottier of the Center for Inquiry and Robert Buckman, a well-known Toronto atheist. Here's the entire show. I don't think any one of the participants is particularly proud of their performance. But see below ....


At one point in the show, the Christian woman, Kathy Shaidle, brings up the "Stalin, the atheist, killed 30 million people (therefore God exists)" argument and Robert Buckman tries to answer in a reasonable manner. He doesn't do a bad job (excerpt below) but Canadian Cynic has a suggestion: What Robert Buckman should have said.

I caution Sandwalk readers that CC's language can be a bit crude ... but it sure is funny.

Nobel Laureate: Kary Mullis

 

The Nobel Prize in Chemistry 1993.

"for contributions to the developments of methods within DNA-based chemistry: for his invention of the polymerase chain reaction (PCR) method"


Kary B. Mullis (1944 - ) won the Nobel Prize in Chemistry for the polymerase chain reaction technique. This technique is used to amplify a given stretch of DNA by repeatedly copying it several dozen times. The technique has been honed and modified and it's now a standard tool in every biochemistry and molecular biology laboratory.

Mullis shared the prize with last week's Nobel Laureate, Michael Smith, who developed the technique of in vitro mutagenesis. I'm not a big fan of awarding Nobel Prizes to those who develop a new technique. I'm much more comfortable with awards to scientists who directly advance our understanding of how life works. That's why my personal favorites are Nobel Laureates like Jacques Monod, François Jacob, Ed Lewis, Otto Warburg, Linus Pauling, André Lwoff, Barbara McClintock, and Peter Mitchell (plus many others).

Fortunately, it usually turns out that the winners of "technology" prizes are very good scientists who have also made a significant contribution to advancing our knowledge of fundamental concepts. That's certainly true of Michael Smith, Walter Gilbert, and Fred Sanger, to name just a few.

Kary Mullis was an unusual recipient in many ways. You can get a flavor for his personality by reading his Autobiography and, especially, his Nobel Lecture. There has never been a speech like that in the history of the Nobel Prize and, chances are, there will never be another.

Read about Kary Mullis on Wikipedia to see what he's been up to since he stopped being an active scientist in 1988. By the time he was awarded the Nobel Prize he was concentrating on being a writer. (This might explain the speech!)

Here's the Press Release describing Kary Mullis' contribution.

THEME:
Nobel Laureates
The "Polymerase Chain Reaction" (PCR)

The PCR technique was first presented as recently as 1985 but is nevertheless already one of the most widespread methods of analysing DNA. With PCR it is possible to replicate several million times, in a test tube, an individual DNA segment of a complicated genetic material. Mullis has described how he got the idea for the PCR during a night drive in the Californian mountains. Two short oligonucleotides are synthesized so that they are bound correctly to opposite strands of the DNA segment it is wished to replicate. At the points of contact an added enzyme (DNA polymerase) can start to read off the genetic code and link code words through which two new double strands of DNA are formed. The sample is then heated, which makes the strands separate so that they can be read off again. The procedure is then repeated time after time, doubling at each step the number of copies of the desired DNA segment. Through such repetitive cycles it is possible to obtain millions of copies of the desired DNA segment within a few hours. The procedure is very simple, requiring in theory only a test tube and some heat sources, even though there are now commercial PCR apparatuses that manage the whole procedure automatically and with great precision.


The PCR method can be used for reduplicating a segment of a DNA molecule, e.g. from a blood sample. The procedure is repeated 20-60 times, which can give millions of DNA copies in a few hours.

As has site-directed mutagenesis, the PCR method has decisively improved the outlook for basic research. The sequencing and cloning of genes has been appreciably simplified. PCR has also made Smith's method of site-directed mutagenesis more efficient. Since it is possible with PCR to perform analyses on extremely small amounts of material, it is easy to determine genetic and evolutionary connections between different species. It is very probable that PCR combined with DNA sequencing is going to represent a revolutionary new instrument for studies of the systematics of plant and animal species.

The biomedical applications of the PCR method are already legion. Now that it is possible to discover very small amounts of foreign DNA in an organism, viral and bacterial infections can be diagnosed without the time-consuming culture of microorganisms from patient samples. PCR is now being used, for example, to discover HIV infections. The method can also be exploited to localise the genetic alterations underlying hereditary diseases. Thus PCR, like site-directed mutagenesis, has a great potential within gene therapy. Without the PCR method, the HUGO project, with its objective of determining every single DNA code in, among other things, the human genetic material, would hardly be realistic. In police investigations PCR can give decisive information since it is now possible to analyse the DNA in a single drop of blood or in a hair found at the scene of a crime.

Another fantastic application is that it is possible to mass-produce DNA from fossil remains. Researchers have, for example, succeeded in producing genetic material from insects that have been extinct for more than 20 million years by using the PCR method on DNA extracted from amber. This possibility has already inspired authors of science fiction. The very popular film "Jurassic Park" is about the fear that arises when researchers using PCR recreate extinct giant reptiles.

Congratulations Carl Zimmer

 
It's often said that "real" science journalists are passionate about presenting accurate science [see Chris Mooney].

Strangely, in spite of this passion, they've tended to remain very silent when a major newspaper publishes inaccurate scientific information—at least in the fields I'm interested in.

That changed a little bit with the George Will affair in the past week. George Will is a Pulitzer Roze winning journalist (not a science journalist). He wrote about global climate change in The Washington Post. Apparently there's another piece in the press.

Carl Zimmer takes him on: George Will: Locked In Ice!. Congratulations Carl! This is why you are one of the best science journalists.
