Pictures Of Winter In Minneapolis


The first real snow in Minneapolis. There was snow as far back as late September, hard on the heels of an eerily summery month, but this one is on the ground until spring. It looks like three or four inches of fine, blowing stuff, and it took me about an hour and a half to scrape sidewalks and driveway.


With the Copenhagen Climate Summit underway, General Obama’s receiving his Nobel on Thursday, and the leak of the “Danish Text,” I probably ought to write about the greenhouse effect. There was an interesting interview in the “Costco Connection,” in which University of Virginia environmental sciences professor emeritus S. Fred Singer, dismisses the notion of human-caused warming, and says that a natural period of global warming ended a decade ago. Singer supports that contention with the statement that “Thirty years of comprehensive satellite observation show a warming in the northern part of the globe, a little warming in the tropics and the southern portion -- and a distinct cooling of Antarctica.” I don’t need climate change on my plate, human-caused or not (although I would probably behave the same, global warming or not), so I hope he’s right. Deconstructing Singer’s statement will take some research. One of the consequences of a contracting economy is frantic periods when you have to put off study, and I’ve been otherwise booked.

On the other hand, a piece in the magazine Ode (for rich people with compact fluorescent lamps) got my Irish up, and an answer came immediately to mind. Brian O’Neill, of Spiked, a British Internet magazine, wrote five hundred or so words under the headline “Who’s Afraid of Billions of People.” He says, “No limits should be set on population growth. I hope in my lifetime the human population on Earth will reach the tens of billions, and it won’t be a problem if it rises to hundreds of billions.” (An Irishman wants more children. Swate sooferin’ Jaysuss! I don't think I can eat that many babies.)

Here’s his case: Efforts to limit reflect a lack of faith in human ingenuity. If you believe in civilization you shouldn’t worry about carrying capacity, because we can figure out how to feed ourselves. More people equal more brains. The population control and reduction lobby has been around since Malthus, and keeps changing its rationale. Malthus said that food supply increases arithmetically, while population increases geometrically. O’Neill says that Malthus didn’t count on the technological innovations of the last two hundred years. Population lobbyists of the early twentieth century were racists and eugenecists, and current anti-birthers want to protect Mother Earth, but whatever our stated reasons, we really don’t have faith in ourselves. We are disingenuous because we say that the planet has a fixed carrying capacity. He points to uranium, which was known to ancients as a mere tint for glass. He says we inhabit only a tiny fraction of the planet’s surface. He finishes by saying, “Anyone who thinks people are a good thing rather than a menace, and believes we can find solutions to our problems, should reject the population control argument and make the case for full freedom of choice on reproductive matters.”

Thank you, Mr. Rand.

Around 1963, Buckminster Fuller said that all of the world’s population, about half what it is now, could be inside, in New York City, doing the Twist. I don’t know how he figured all of that city’s floor space, but okay... I wondered about now. I did the Twist in my kitchen, and measured the area required, sixteen square feet. I multiplied sixteen by 6.8 billion, divided by the number of square feet in a square mile, and got Iceland. Imagine, every wonderful ingenious (and ingenuous) human soul dancing to the music of Chubby Checker, under the midnight sun. The volcanoes would probably erupt.

Look, I understand that you can’t prove a negative, and I don’t want to be like those nineteenth century scientists that didn’t think we could survive speeds of sixty miles an hour, or build flying machines, but here’s the deal. We need various resources, metals, soil for growing food, etc. We took the easy stuff first. We started out getting iron from hematite, now we’re down to taconite. It takes more energy to use the resources we’ve left ourselves with, and we’re running out of high-quality fuels.

Maybe we can jump off cliffs and sprout wings, but I don’t think so. Maybe we can make energy from water and sand, but you need electricity to get hydrogen from water, and the energy return on investment for photovoltaics is about eight percent.

The Green Revolution did increase crop production per acre, but at the cost of reducing it per calorie, and production per acre has stalled, as energy has become dear. We might increase land under production, but once again, we started with the best land. O’Neill says that forty-six percent of British land is used for agriculture, and eleven or twelve is wooded. His context here implies that there are still plenty of places to stack Brits, but this raises the issue of opening new land (the other forty-two or forty-three percent) to agriculture production. I’m all for eliminating lawns, but is that what O’Neill is calling for?

His comment about people’s, thousands of years ago, thinking of uranium merely as an interesting rock, makes me wonder if O’Neill thinks ingenuity equals nuclear power. I’m not as excitable about ticking Geiger counters as a lot of people, but I have to insist that there are problems with nukes that I haven’t heard solved, and there’s not a whole lot of precedent among the other species for playing with radiation. Nuclear power’s energy return on investment is about three percent.

I believe in human ingenuity, too, but I’ve driven enough miles in city traffic, and watched enough people ignore exercise etiquette at the gym, to take it for granted. And don’t forget the US’s 108th Congress. I believe in human ingenuity. I yearn for it. But when it comes, there’s only so much it can do.

(Thanks to Marissa for the Jonathan Swiftie!)

Undoubtedly but we can't fix what we can't understand and we understand so little of how the world works,how systems function and we continue to do stupid things because scientists don't view research holistically.
The world will warm, the world will cool as it's always done but some of the damage we've done can't be undone.
Beautiful snow!One of the world's great wonders.
