Perhaps the reason is that on-line access is better? This CCSU statistic suggests you may just not be very good at selling obsolescent technology.

Sorry but criminal history is not a proxy for race*. Race predicts recidivism independently**. Community disadvantage is also an independent predictor**, so you can't just blame poverty either. There's deep problems that have led to this situation, and we're never going to fix them if we put on our social justice blinders and deny the reality that certain races commit more crimes than others in a lot of categories, especially violent crimes. It's critical to address the large scale societal mechanisms behind this (and while racism has its fair share of the blame, it's absolutely not the only factor), but in the mean time, it's reality, and you can't eliminate a valid independent variable just because it offends your sensibilities.

for me the greatest clincher for man-made global warming are these two graphs:
  atmospheric CO2 450,000BC to present
  atmospheric CO2 1000AD to present

the first graph shows that the CO2 level has hovered between 200 and 300ppm for 500k years. so our current co2 concentration ~400ppm is unprecedented in the history of mankind! The graph also shows that global temperature is highly correlated with CO2 concentration.

the second graph shows that for most of the past millennium the CO2 level has been hovering at 290 ppm, which is consistent with the past. But in the past 100 years it steadily shot upwards! My conclusion is that this is strong evidence that CO2 increases are due to the large scale burning of fossil fuels that began with the industrial revolution and kept going until today. my further conclusion is that if we reduce our CO2 emissions we can bring the CO2 concentrations back to historical levels.

Here's another interesting graph:
atmospheric carbon dioxide, 500 million years ago to present

That graph shows that carbon dioxide levels were up to about 7000 ppm about 500 million years ago. Then carbon dioxide levels dropped dramatically to reach a low 300 million years ago. Wonder if there is a scientific explanation for why it went so low 300 million years ago? Then it went back up, and dropped down again to the present day.

Here's the thing: if carbon dioxide levels were over 2000 ppm 175 million years ago, there should be some traces of global warming dooom from back then. Climate Change Doom Warning Experts don't have to make speculative predictions of doom. They can look at what happened the previous times carbon dioxide levels got high, and use that as the base for their doom predictions.

Having lots of carbon dioxide in the atmosphere isn't unprecedented. Probably the same thing will happen again as happened the last times there were high carbon dioxide levels. But what happened last time? That's what some Climate Change Experts should find out, as quickly as they can!

this is my conclusion; you may look at the same evidence and come to the same conclusion. But the important thing is to teach our children the critical thinking skills to evaluate this data. If you white wash science classes then you lose the chance to develop these skills.

At least that's what my GF tells me.

I know it's been hotly debated, but some argue that Prius Outdoes Hummer in Environmental Damage. I know others have tried to debunk this claim, but I am not convinced either way. A lot of the reactions to this argument sound very emotional. Science is supposed to be dispassionate.

...is how much more environmentally damaging *creating* the batteries is. According to this, and this, the damage caused is greater than that of a Hummer.

How this could happen is pretty simple, really. While internal combustion is inherently polluting, it's been one of the most developed products for the last one hundred years, and so the production processes are super streamlined. Battery and hybrid technology is new, and so it has a few kinks still to be worked out.

People need to be careful about jumping on this 'green' bandwagon without thinking, because there's a lot of stuff out there designed to take advantage of the near-maniacal devotion to curbing our carbon emissions, even though there's no way to conclusively prove that our output (which is 3% of total output, rotting vegetation contributing to the vast, vast majority) is actually doing anything at all.

Believe what you will, but please do investigate both sides of the matter first, and remember that it's not what you drive, it's HOW you drive.

there's more

Don't forget the extinction of entire species of animals and environmental devastation caused by massive pollution and climate change as some of the costs of using alternative fuels, too.

What, you think those solar cells and batteries are made cleanly? Hmm...

Resisting the urge to make a comment pertaining to a particular "smug" southpark episode... I'd still like to point out that I've read in a more than one places (including I think a slashdot article a bit back which cited the same data I'm posting here) about how the Prius from construction to disassembly at End Of Life, is a TERRIBLE car for the environment.

In fact a little bit of research (not saying this is accurate, just something to think about) leads me to a report comparing the overall cost per mile taking into account manufacturing, repairs, and consumables (ie gas and oil and batteries if applicable). The industry average that they came up with is $2.281 per mile. The Prius costs $3.249 per mile as compared to the most expensive (a Maybach $11.582) vs the cheapest (Scion xB $.478). As another example, the Corvette costs $3.158 per mile.

By their math (again, not saying it's correct, could be FUD for all I know) I'd be better off buying a Corvette than a Prius. Now to be perfectly honest I disagree with a lot of their math, HOWEVER that isn't the only source I've read it from. Their numbers may be FUDdy but Other sites reach some of the same conclusions albeit in less objective way.

I am not what you'd consider an environmentally conscious person. It isn't that I drive a huge truck (VW GTI which gets fairly good gas millage out of it's 1.8L Turbocharged engine and is fast to boot). The fact is there's far more to a car's environmental impact than strictly going by MPG. And thus, your argument that there's more than just cost that dictates how good something is for the environment... well take it with a grain of salt is all...

And then of course there's other cars that get very close to the Prius in gas mileage, that cost a lot less, and don't have polluting batteries in them...

I'm actually not against the Prius, I think it was an important first step in the American psyche that we are open to listening to alternative energy ideas, it was IMHO the first successful/popular hybrid car which shows that Americans are willing to shell out for a greener (if only in theory) car. Which means the Big Three will shell out money for R&D. I just don't like people getting up on their high horse because they own a Prius.

I don't think disappointed is the world I'd use. I think idiotic is more like it. See this article:

http://clubs.ccsu.edu/Recorder/editorial/editorial _item.asp?NewsID=188

The Prius causes more environmental damage than a Hummer. I'm sick of the Hybrid propaganda that's based on trendiness instead of science.

Don't know for sure if the parent is completely correct, but this article sure makes an interesting read: http://clubs.ccsu.edu/recorder/editorial/print_ite m.asp?NewsID=188

> Ah, more hybrid misnomers. If you don't understand the battery technologies involved (Ni-Mh in current models), don't comment. Ni-Mh is not
> "environmentally-disasterous" - in fact, the Ni in the battery is so valuable that Toyota pays a $500 per pack bounty for recycling.

The batteries in the Prius use Nickel (Ni). How do we get Ni? Here's how Toyota gets the Nickel used in the Prius.

From http://clubs.ccsu.edu/recorder/editorial/print_ite m.asp?NewsID=188:
[ The plant is the source of all the nickel found in a Prius' battery and Toyota purchases 1,000 tons annually. Dubbed the Superstack, the plague-factory has spread sulfur dioxide across northern Ontario, becoming every environmentalist's nightmare.

"The acid rain around Sudbury was so bad it destroyed all the plants and the soil slid down off the hillside," said Canadian Greenpeace energy-coordinator David Martin during an interview with Mail, a British-based newspaper.

All of this would be bad enough in and of itself; however, the journey to make a hybrid doesn't end there. The nickel produced by this disastrous plant is shipped via massive container ship to the largest nickel refinery in Europe. From there, the nickel hops over to China to produce 'nickel foam.' From there, it goes to Japan. Finally, the completed batteries are shipped to the United States, finalizing the around-the-world trip required to produce a single Prius battery. Are these not sounding less and less like environmentally sound cars and more like a farce? ]

Please explain why the Prius batteries aren't an environmental disaster.

PS: The funny thing is that, according to the quoted article, a Hummer H2 is more environmentally friendly energy wise.

Clayton College and State University in Morrow, GA required all students to have laptops starting in 1999. In fact they went one step further, They made it a point to buy all the laptops and give them to the students. Students had a $75 technology fee IIRC per semester, and were required to have their laptops available in class at anytime.

The biggest advantage was instructors/professors knew that all students had access to a computer. For the IT program it was nice simply because there was one less excuse for a student not to finish his or her work. For other programs, the laptop got in the way of the teaching. You had Instructors who were feeling obligated to find some use for the laptops in Math, Music, and Art classes, which didn't always lend a natural fit. The program was modified in 2002 so that students were required to purchase their own laptop. I was no longer involved at that point so I am not sure what happened after that, but I believe it was finally ended in 2004.

And everyone knows that archeologists love to invent stuff, right?

The history of Archaeology is rife with everything from blind faith to deliberate deception. Lucy? Found to be false. Piltdown man? False. Cromagnon man? False.
