There’s a pretty good article in the September Atlantic about global warming (“Some Convenient Truths” by Gregg Easterbrook). Mr. Easterbrook makes the point that global warming is an air pollution issue, and thus far, humanity is batting well over .500 with air pollution issues. Once the USA and the other industrial nations decided to do something about smog, ozone depletion and acid rain, progress came more quickly and more cheaply than was thought possible. Right now, greenhouse gasses have everyone spooked. The Republicans stayed in denial as long as they could, but the scientific evidence is now quite strong. So they have shifted gears in their arguments against Kyoto and other proposed global warming efforts. They now argue that the problem is too big; in order to really change the situation, we’d all have to go back to living in teepees and riding horses. Unfortunately, the Democrats (Al Gore and his “Inconvenient Truth” lecture and movie) play into this line of thought. Mr. Gore says that we’re all going to have to live with less in order to avoid raising the oceans by 20 feet and flooding out the coastal areas where roughly 40% of humankind now lives.
(Of course, the Republicans make it sound much worse than it might have to be. Perhaps with some technology and emission credit markets, we could all get by with driving small cars, using public transit when possible, eating vegetarian foods, and living in houses or apartments having around 400 square feet per person. I do that right now!)
Mr. Easterbrook argues that it’s time to get optimistic and get busy about global warming. He says that Democrats should reaffirm their trust in big government and Republicans should reaffirm their faith in technology and capitalist innovation. As with smog, ozone depletion and acid rain, big government should call the tune, and innovative capitalists should figure out how to dance to it. In other words, let’s go back to the mix of capitalism and socialism that hasn’t always been pretty, but has served America rather well since the Great Depression (despite efforts to take it apart by Ronald Reagan and now G. W. Bush).
Personally, I’m all for turning back the Bush Revolution and returning to the regulated capitalist economy of the 1950s and 60s. I really hope that the Congressional elections this fall will convey a similar mood on behalf of the American public (and if so, I hope the Democrats will pick up on it; right now they are still a bunch of whimpering cowards).
But as to whether we can count on technology to come thru again with regard to global warming, as Mr. Easterbrook seems so sure of . . . . . I’m not sure I agree. The other air pollution issues Mr. Easterbrook cites involved chemistry that was somewhat optional to the underlying processes. The substances at issue represented “one way to do it”, i.e. one way to accomplish greater efficiency or greater effectiveness in running a motor or cooling a refrigerator. With some tinkering and testing, it wasn’t so hard for chemists and engineers to find another way to do the same thing, sometimes even better than the original way.
However, carbon dioxide (the main greenhouse gas) is a lot more fundamental to the energy process than nitric oxides (smog) and sulfur dioxide (acid rain) were. If you burn anything with carbon in it, you get carbon dioxide. So why not burn hydrogen instead of coal, oil and gas? Fine, but to get hydrogen, you have to run electricity thru water, and to get that electricity, you have to first burn coal or oil, i.e. something with carbon. Then why not go nuclear? Because we still haven’t figured out what to do with all the nasty radioactive crap that nuclear plants leave behind. How about solar, wind, geothermal, tidal generators, etc.? Cool, but it takes a lot of investment to set those things up and you don’t get nearly as much energy [yet] for each dollar of capital invested into a wind farm or solar panel that you get from a coal-fired electricity plant. Since our economy has only so much capital to invest, alternative energy can only do so much; the technology is just not there yet.
Right now, about all you can do with carbon dioxide is to suck up the exhaust put out by power plants and hide it somewhere, probably deep under the earth. There doesn’t appear to be an easy and cheap way of turning carbon dioxide back into pure carbon and oxygen. You’re dealing here with fundamental chemistry and physics, the basic thermodynamic laws that govern our planet.
Over the past 10,000 years or whatever, the human race has dodged a whole lot of extinction threats by using its brainpower. It’s arguable that the power of the human mind in coming up with new technologies and better medicines and improved economic systems has made things better for all of us. I myself would agree, but the human mind still has a whole lot of work to do in recognizing and getting around it’s evolutionary bias toward tribal aggression. We’re still using our technology to kill each other more effectively; we still don’t see the deadly game that we’ve locked ourselves into. We still haven’t taught each other to share in those ultimate words of hope, i.e. “it doesn’t have to be this way.”
But back to global warming. I honestly wonder if this is where the technology-fix road comes to an end. Carbon dioxide is a very, very basic substance. Technology will certainly help to deal with it, but you may not be able to just make it go away like CFC’s. Permanently disposing of excess CO2 may make dealing with spent uranium fuel from nuclear power plants look like child’s play. Bottom line, it’s probably gonna be expensive. And the longer we wait, the worse it will get.
Therefore, there may be good reason why Al Gore and other global warming activists aren’t rushing to “give in” to techno-optimism like Mr. Easterbrook has. Solving the problem of global warming may yet require global-scale sacrifice regarding standards of living. And even if the necessary sacrifice is mild, sacrifice is not something that humankind does very well on a global scale. That old fashioned, hard-wired tribal aggression instinct kicks-in pretty quickly. The many tribes of the human race already have a long list of reasons to go to war with each other. The question of just who is going to give up their creature comforts because of all the coal and oil that the western world has burned over the past century or two is probably going to add to that list.
When I was around 12 or 13, I was very interested in science and chemistry. I knew what carbon dioxide was; I even used it once in a class presentation (more on that below). And I remember thinking to myself just how boring carbon dioxide was. I couldn’t imagine how anyone other than a few nerdy engineers working on certain kinds of chemical plants or machines would ever have to get interested in the stuff. Wow, I was really wrong there; little did I realize that carbon dioxide is just like the comet in Deep Impact or the asteroid in Armageddon. It’s a serious threat. And this time, it’s not a movie (“Inconvenient Truth” not withstanding).
(As to the class presentation: back in 8th grade, me and another guy had to give a short lecture about the growth of industry in China. So after gleaning a few facts about China from an encyclopedia, we got some balsa wood and built a model of a factory. Then we got some pipes and hoses and plastic containers, and rigged up a way to get hot water into a container with dry ice. Dry ice is frozen carbon dioxide. The concentrated carbon dioxide gasses that were given off as the dry ice melted in the water then came up thru the chimneys of the little factory, looking just like smoke. As such, we were releasing carbon dioxide and contributing to global warming. Little did we realize just how accurate our little Chinese factory model was!)
