You may not say I'm guilty of a fallacy, I'm saying you are. It's almost as if you think simply stringing long lines of words together in some semblance of a sentence somehow represents a critique. I hesitate to call what you're line of argument has devolved to a game of semantics. More like a game of alphabet soup.

Are you trying for the Logical Fallacy of the Year Award here? The point of AGW theory is that the changes we are seeing are not natural in origin. Instead of playing semantics, deal with what the theory states. Invoking private definitions is probably the lowest form of debate, because it's useless and accomplishes nothing.

I'm sure it's the same down in Washington State as it is up here in coastal British Columbia. Low snow pack means lower river levels, which means potential problems for irrigation in areas under cultivation, harm to fish stocks, and the potential for severe water restrictions in some areas.

I own some property out in a rural area of Central Vancouver Island, and while my house is on a civic water system, my kid and her partner live on the property in a house that gets its water from a creek that flows beside the property. They also raise pigs, using my water license. The creek swells up during rainstorms (like the one we had over the last day or so), but all in all, it's very low compared to other years this time, and I'm seriously worried that we may have to put everything on the civic system, or dig a well, and both cost $$$.

It also brings to mind the previous winter, when we had to put a new water line from the creek into the kids' house in the middle of December. First of all, it was about six or seven degrees celsius (42.8F), and I was literally clearing out the trench in jeans and a t-shirt. The soil itself, a sandy loam common in our area, was damned near bone dry a foot down. The back hoe operator was pretty amazed, and it demonstrated how the 2013-14 winter was very dry (though it did have longer cold spells).

The final anecdote to my story is that I grew up on the property, and when I was a kid back in the 1970s and 1980s, we used to skate at least two to three weeks every winter on the big pond, but now, even in the hardest cold snap, I'd be very nervous about walking far out on that ice. It just doesn't simply get as cold on Vancouver Island as it used to, and all that precipitation that should be hitting the coastal mountains and forming a good snowpack that lasts well into summer is just falling as rain.

No kidding. Here on Vancouver Island, other than perhaps a four or five day stretch back in December with sub-zero degrees celsius temperatures, and the odd day here and there of frosty mornings, we literally did not have a winter.

There seems to be this popular attack of AGW that involves "Look outside, if it isn't a desert, all those scientists are evil liars!"

Because the changes in this case are not natural at all?

Saying "climate always changes" is like saying "water always flows", and then promptly putting a firehose in your living room and then turning it on. I realize you think this is a great rhetorical trick, but that's all it is.

If this technology becomes common place, I expect those with crustacean allergies will be required to wear a red tag same as those with pencilin allergies.

It might even become practice to use it anyway and follow up with a treatment for the anaphylaxis, if the bleeding is severe enough. People can survive shellfish reactions with management - severe internal bleeding, not so much.

This is the first article I've seen that explains well how GPUs can/are being used for practical applications along with what can be achieved and some of the issues.

GPU's have been used for all sorts of "practical" computations for half a decade now, but the really interesting part here is that CFD has been particularly GPU-resistant using existing algorithms. See the Xeon Phi processor, etc. for non-GPU approaches to throwing dedicated hardware at the problem. It's easy to underestimate the enormity of this quote, but "starting from scratch" when necessary is something SpaceX excels at:

I am grateful to SpaceX for allowing us to basically start from scratch on CFD and in many ways reinventing the wheel.

It's hard to gain sufficient insight from TFA but it sounds like this is as big as hidden-line-removal in computer graphics and that they've moved CFD to the boundary conditions and made that GPU-computable, which is like solving two or three orders of magnitude at once.

You are assuming we have to pander to pilots preferences. Just TELL them, "you will be videoed or alternatively you can choose another profession".

And some percentage of them will, which makes the available pool of pilots at a given price smaller, resulting in either lower quality or higher prices or both.

Could you elaborate on what you mean by "alter orbital structure and energy levels"?

I mean part of the electrostatic attraction between atomic nucleus and orbiting electrons should be countered by expansion of space between them, which in turn affects stable electron orbits. In fact all forces should get weaker with distance faster in an expanding space than in flat space.

Electromagnetic force is mediated by virtual photons, who's wavelength gets longer as space expands, thus sapping electromagnetism of some of its native strength and somewhat altering the lowest-energy point of all structures held together by it.

I was a little confused when I saw that wording in the story, and now that I'm hearing this wording is the important part, I'm getting a little concerned. Are we not all citizens? Have we been divided into citizens and ruling class, now?

We've always been divided into serfs and lords. Human spirit simply doesn't have the strength to resist using power to get more. The lords, blinded by the seeming invincibility of their position and the system which grants it then end up draining that very system to the point of collapse and revolution, and the cycle repeats.

Whether it can be broken is anyone's guess. Democracy has slowed and complicated the gravitational collapse of current system somewhat, but it couldn't alter the end result, since all manifestations of power in our societies are not under democratic control, and are thus free to join biggest existing masses of power and make them even bigger.

I'm all for popularizing science among all citizens, but I'd rather we word that as "science for the masses" or something.

That very desire should already answer your question. As our masters keep telling us: if you have done nothing wrong, you have nothing to hide.

they could sit down and face the fact that there is clearly too many people in the area

Red herring. Residential use in California is about the same as what's used for almonds alone. And much of that residential use is by 1%ers on lawns, swimming pools and golf courses. California has more than enough water for it's people. What it doesn't have is enough water to use billions of gallons on thirsty rice, almonds, fracking, etc.
