This has very little to do with UAVs, or whether old ones have the capability to encrypt, etc.

This has to do with the fact that there are far more receivers in the field than UAVs, or other transmitters. And those receivers cannot decrypt, so everything in the arsenal that wants to transmit to these ROVER portable receiver units has to do it unencrypted.

Actually, CO2 in the atmosphere has been increasing since before 1950 - it has simply accelerated since 1950. But, nice try showing a graph whose horizontal axis only covers the latter half of the 20th century.

This more recent increase is entirely consistent with the increased pace of industrialization, the fact that warming also causes the release of more CO2 (from oceans), and the fact that we're starting to exhaust some of the natural CO2 sinks (e.g. oceans) that have been helping to mitigate some of our CO2 contributions.

So, regardless of whether many skeptics say it or not, it's wrong, and thus, so is your logic. How does stuff like this get modded up to 5?

Yes, a healthy bit of skepticism is ALWAYS a good thing. Especially when it causes us to sit on our asses while we destroy our own habitat. Wake the hell up!

Can we get past the stupid psychological crap and just focus on some actual data? Instead of rationalizing your sit-on-my-ass attitude by claiming that skepticism is always good, why don't you read through some of the data and propose an alternate conclusion? Otherwise, save the human interpersonal dynamics nonsense for the oprah.com message boards.

Allright, Game Theory Boy. Presumably you know what a Prisoner's Dilemma is. In that scenario, participants can (correctly) pick the strategy that maximizes their outcome, and yet still will achieve a societal result that's suboptimal for the whole system.

The key feature of a prisoner's dilemma is that participants ARE NOT COOPERATING. If they do cooperate, they can pick individual strategies that leaves society in a better position. So, the question is, is the human inhabitability of our planet worth cooperating for, or should we just throw up our hands and say, "let's just keep sinning"?

Whose actions do fill you with confidence? Seriously?

The world is full of douchebags. I think most of us slashdotters think we're the cream of the crop (and we're right, of course!) .... but you can't discredit a major theory simply because everyone associated with the issue isn't saintly. That's simply not logical.

The only relevant question should be whether these scientists fill you with MORE confidence than the energy industry, anything-to-avoid-paying-taxes crowd on the other side of the issue.

Well, what's your answer?

It's worked with cigarettes. I'll take that over your hypothetical internet tax scenario, anyday.

The unions are not responsible for all the workplace protections and benefits in place at non-unionized workplaces. In fact, in my time at a large DJIA company, that had union machinists, and non-union workers of other disciplines, it was most definitely the case that the lazy union bastards were taking compensation from the rest of us. They typically went on strike every time their contracts were up, got cushy packages, and then the rest of us got shafted because the company had nothing left after the union bent them over.

Ralph Nader single-handedly has won the American worker as much as all the major unions combined.

UAW workers make more than their southern counterparts, and ... wait for it ... get more in benefits, too. All told, that's a significant bump in total comp, despite the fact that an auto worker is an auto worker. UAW guys aren't any better at what they do than Toyota's guys. What makes your comment even more ridiculous is that it ignores the fact that those non-union counterparts in the South work for companies WHO ARE KICKING GM, FORD, AND CHRYSLER'S ASSES. Why should employees at underperforming companies make even a single dime more (plus more expensive benefits) than their competitors who are beating them soundly in the marketplace?

Finally, please don't ignore the fact that unions make companies less competitive, which indirectly brings down compensation for everyone at those companies. Don't agree with that statement? Please name for me one company who's leading their field, with a significantly unionized workforce, that competes against competitors who aren't unionized?

My guess is that the rats did ok, because you guys reversed the valve, and were actually pumping the diesel fumes into your lab. Your "vague memory" is probably another side effect of this occupational exposure.

Seriously, is this an Exxon Mobil employee? Go stand next to a diesel bus for 10 seconds, and tell me again how benign diesel exhaust is.

So, by this rationale, in order to get more top talent in science, we need to let more talent choose other fields, leaving a scarcity of science grads, which will drive up salaries, and lead more top talent back into science? That's kind of like the argument that cold water boils faster than hot water. Of course, lots of people think that's true, too.

Along the same lines, I'd like to hear the author's explanation of why employees in finance continue to get paid more and more, even as more talent floods into that profession.

Not every price is set solely by supply and demand. In this case, I think culture has a lot to do with it, as do negotiating skills (which geeks don't generally have in abundance). Science and math types are still considered dorks, and the leeches who work on Wall St. or Madison Ave are the cool kids. Fewer science students isn't going to change that.

That's probably because you don't have much on your Win7 install yet, and your old XP system has tons of stuff.

Why do we need to rehash this every time WIndows comes out with a new version? Windows runs well, until you get it a few iterations away from a clean install, and then it bogs down. The registry is clogged, it takes forever to do things that should be instantaneous to a human observer, and we all wind up realizing "Oh yeah, this is still just Windows".

Is there any reason to think that your Win7 system won't run like a dog in a year or two?

If ice moving from land to sea were the only factor, then your description would be accurate. However, it's not the only factor, so your description is garbage.

The reason that ice is melting is an increase in air temperatures, which acts not only on the ice, but also on the oceans. So, while ice melting into the water cools the water, it doesn't do so more than the warmer airs warms the water. The net effect is still ocean warming, not cooling.

If simply transforming land ice into cold water, and moving it into the sea could produce more sea ice than the land ice you lost, you would truly have a significant thermodynamic result. But, that's not what's been observed over a period of decades.

The earth is not a closed system. It continuously receives external energy inputs from the sun, and leaks out energy via infrared radiation. Changing the insulation in the atmosphere can affect the total energy balance of the planet. Please take time to learn some thermo yourself before lecturing others, and labeling them dumbasses ... Dumbass.

Where is this lack of publishing data that you refer to? Thousands of detailed studies, and the data they are based on, have been published. Much of the data is government property, and publicly available. Climate science is no different than any other branch of science in this respect. Does absolutely every scrap of paper used to define every algorithm get published with every peer-reviewed paper? No. Again, does this cause you to doubt the results of all other scientific works?

What you don't seem to understand is that this issue is not merely one of academic science. It's a strategic issue. If you were presented with the scenario that upon the roll of a die, you would be unaffected should the die land on 1, and for all other results (2 through 6), your house would burn down, wouldn't you go out and purchase fire insurance BEFORE the die was rolled? Or would you wait until after the roll, to have PROOF that it landed on 2-6, before you'd be willing to purchase the insurance?

Lemmings are fearless. Does that make running off of cliffs any better?

I hear lemmings also rarely get bogged down with debate. Maybe you have something here ...

I agree with your contention that the best place to locate solar panels is in the desert.

But, I think you've missed the boat with the heat analogy entirely. I can imagine that a panel on top of a car in a desert race would heat up, but that's not what this project is building. The panels will be located on an enormous heat sink that's always cool, no matter what the air temperature is. Have you ever been in a hot desert? Just dig a few inches under the top layer of sand, and it cools down dramatically. This is why heat pumps work (to cool building down).

The contact with car tires will also be multiple inches of glass away from the panels themselves. They're not going to be heating the panels up.

And of course a traditional road gets hot. That's the whole point behind the promise of this technology! That's the enormous amount of solar energy. On an asphalt road surface, that all gets converted to heat. Solar panels are dark, too, but they're using the photons to generate electricity, instead of solely heating the road surface. Such a road would also lose some incident energy to reflection, which asphalt does hardly any of.

I'm not saying heat is a non-issue, but I think your example is a poor one, that overstates the problem.

Oh please. Stop pretending that green this or green that is even remotely popular with politicians, or any other segment of our society. For every green endeavor you read about, there's 10x as many black ones (black as in oil, black as in coal, black as in asphalt, etc.)

Our government gives away far more of our money to big polluters than to all the pie-in-the-sky green projects put together. Go actually read the stimulus bill and then try to refute my point.
