Geoengineering

I have to say that I’m (slightly) encouraged that the new science advisor is willing to consider planetary modification as a solution to global warming, in the event that it actually turns out to be a problem bigger than the current preferred cure. But I think that Mickey Kaus infers too much, unless he’s seen more specific proposals than appear in the WSJ piece:

If shooting particles in the air can semipermanently change the climate of the entire planet … well, in the hands of well-meaning people it would be a risky, last-ditch policy to combat global warming. In the hands of less benevolent people it could become a heavy duty terrorist weapon, no? … If you have the missiles, is it that much easier to develop nukes?

Well, first of all, having missiles doesn’t help at all with developing nukes. They are entirely independent technologies. It might help in delivering nukes, if (as I pointed out in the New York Times) you can build the nukes small enough to fit on the missiles, and if you can also build an entry vehicle that can deliver it to a desired target (and yes, I know that the guidance doesn’t have to be that precise to simply take out a city, as opposed to a silo).

But even more to the point, nowhere did I see the suggestion that it would be done with “missiles.” I had an argument with an idiot at Free Republic a year or two ago when this notion (putting particulates in the upper atmosphere to block the sun) came up. He pooh poohed it, on the basis that rockets cost far too much, and made a stupidly ridiculous cost estimate based on Titans (which no longer even exist).

But if this were to be done, it wouldn’t use missiles. As I point out in the previous linked post, this would be an excellent market for reusable suborbital transports. And if you’re worried about suborbital transports as terrorist or rogue-nation weapons, you don’t understand their nature (at least for the short distances that satisfy either tourism or seeding particulates in the upper atmosphere). They would actually be less useful than aircraft, as a result of their limited range and payload.

How Did It Go?

Here’s a graph of Anti-HumanityEarth Hour’s effects in California.

It doesn’t really surprise me. Even if a lot of people dimmed lights, the amount of electricity used for lights in CA isn’t that huge a percentage of the total demand. For instance, one of the biggest drivers, particularly in the Bay Area, 24/7/365, is server farms, and no Virginia, even in the land of fruits and nuts, they’re not going to shut them down for a stupid political propaganda stunt.

The Naturalistic Fallacy

10 Comments

John Tierney has some thoughts on, and from Freeman Dyson, that seem appropriate to last night’s nonsense:

The disagreement about values may be described in an over-simplified way as a disagreement between naturalists and humanists. Naturalists believe that nature knows best. For them the highest value is to respect the natural order of things. Any gross human disruption of the natural environment is evil. Excessive burning of fossil fuels is evil. Changing nature’s desert, either the Sahara desert or the ocean desert, into a managed ecosystem where giraffes or tunafish may flourish, is likewise evil. Nature knows best, and anything we do to improve upon Nature will only bring trouble.

The humanist ethic begins with the belief that humans are an essential part of nature. Through human minds the biosphere has acquired the capacity to steer its own evolution, and now we are in charge. Humans have the right and the duty to reconstruct nature so that humans and biosphere can both survive and prosper. For humanists, the highest value is harmonious coexistence between humans and nature. The greatest evils are poverty, underdevelopment, unemployment, disease and hunger, all the conditions that deprive people of opportunities and limit their freedoms. The humanist ethic accepts an increase of carbon dioxide in the atmosphere as a small price to pay, if world-wide industrial development can alleviate the miseries of the poorer half of humanity. The humanist ethic accepts our responsibility to guide the evolution of the planet.

Like Tierney, I am firmly in Freeman’s camp.

…and yet so far.

I’ve been slowly bringing my Fedora Core 9 box up to full utility, and had a major breakthrough today, in that I finally got flash/shockwave running in Firefox. The problem now? No sound.

When I go System/Preference/Hardware/Volume Control, I get the message: “No volume control GStreamer plugins and/or devices found.”

I’ve checked, and Gstreamer and Gstreamer-plugins-good are installed. I tried G*-plugins-bad and ugly, but they weren’t to be found in the repository (is this a 64-bit problem?). Anyway, anyone have any idea what the problem might be? Is there some command line to detect the sound card (it’s built into the board)?
