Is Obama, or would McCain, be better for the environment?

(Is the jackalope a product of the law of unintended consequences?)

It is nearly impossible to be a blogger and not comment at least once on the presidential race of 2008. For starters, I will put my cards on the table and tell you that I was for Barack Obama all the way. My wife and I first got excited about Obama when we heard him give a speech in the Jewish synagogue in downtown Denver, Colorado in March 2007; later that month my wife and I put “Obama for President” bumper stickers on our car. By the way, that car is a SUV, so you now see all my cards.

But the question here is which man as President, McCain or Obama, would be better for the environment. The answer to that important question is not abundantly clear to me, and in thinking about it, I realize how complicated and convoluted the answer could be. Traditionally, we environmentalists tend to think that Democrats are more favorable for the environment than Republicans. However, the Endangered Species Act of 1973, the conservation legislation that many tout as the single most important environmental law ever written, was enacted under the Republican Richard Nixon. On the other hand, President Reagan (a Republican, who is quoted as saying “If you’ve seen one redwood tree, you’ve seen them all”) appointed James Watt as Secretary of the Interior, which most environmentalists considered a disastrous choice for such an important position as the manager of the nation’s natural resources. Generalizations seem to have low predictive power in this kind of analysis.

Here is a brief and highly simplistic analogy to demonstrate how there can be both intended and unintended effects on the environment. Let’s consider two families in the U.S., the Greens and the Slobs. Mr. and Mrs. Green read Al Gore’s book on global warming and they took it seriously. They turn off the lights when they leave one of the rooms in their house, they run their major appliances at off-peak hours, and they bought a small car (their second car) that gets 35 mpg. They built their 3,500 square foot house, well-insulated, in the woods from which they drive 10 miles to get to work everyday. They take a winter skiing vacation in Colorado and a summer vacation to Europe or Costa Rica most years that, of course, involves flying. Did I mention that the Greens have three children and two cats?

The Slobs haven’t read a book in a decade (the last was a Danielle Steele romance novel), they keep their electric home really warm in the winter and really cool in the summer, and they even throw trash out of their car when driving down the road. The Slobs live in a 1,500 square foot house in a run-down suburb of a major city. The Slobs drive an SUV, but they live only about 1 mile from their jobs. Their vacation in the summer involves driving to the beach about 50 miles away and staying in a cheap rental for a week with their only child.

If we were to do a carbon footprint analysis of these two families, it would surprise no one here that the Greens contribute much more to climate change than the Slobs, even though the Greens are trying to do their best. In fact, the two additional children that the Greens have will, alone, result in a much greater impact on the environment over the roughly 75-year years in which those two humans live in the U.S. than any energy the Greens could possibly save while those children are still living in their home. During those 7-8 decades, those two additional humans will consume tons of raw materials in the products they buy, use millions of joules of energy, and generate hundreds of tons of waste. In the short run, the Greens are also responsible for permanently eliminating a chunk of habitat from the forest in which they built their house, reducing and/or degrading biodiversity in the process. In short, although the Greens “intend” to reduce their impact by watching their energy consumption and their waste generation, their “unintended” impact is much greater than the Slobs, who are basically clueless about the whole issue. And if we compare the Greens to almost any of the 4-5 billion people living in developing countries, their relative impact is enormous.

Obama and McCain both intend to cut carbon emissions by 2050: Obama wants an 80% reduction over 1990 levels and McCain wanted a 60% reduction. Both of them have opposed drilling for oil in the Arctic National Wildlife Refuge. The League of Conservation Voters graded each senator’s lifetime voting record in 2008 with regard to environmental issues—McCain got 24%, Obama got 86%. Overall, Obama seems to be the candidate likely to be better for the planet, a conclusion also reached by others who are examining this issue (http://www.observer.com/2008/obama-vs-mccain-environment-opening-bell).

What about the unintended consequences? What if Obama, who has written a book about being hopeful, engenders enough optimistic feeling in the U.S., or even the world, that the birth rate ticks up .1%-.2%? Sounds far-fetched, but birth rates historically increase when people feel the future is going to be bright. Or, what if McCain had been able to stimulate the housing market to the extent that several million more houses were built than would otherwise have been the case? All economists think this would be a good thing, but try to estimate the increase in energy consumed, habitat lost, and materials used. Both candidates promise to stimulate economic growth and lower gas prices, but this tactic is almost certainly bad for the environment. For example, lower gas prices stimulate greater use of that resource and contribute more to climate change. These are enhancements that might be “good” for most of us in the short term, but be “bad” for us all in the long term. Isn’t this the classic dilemma?

Most of us do not engage in very deep analysis of these environmental issues, even when a general election is at stake. We take at face value what each candidate says they are going to do, compare what they say, and make a decision. My argument here is not that they may be lying, or naïve, or simply misinformed about what is possible to accomplish. That may be true. I am arguing that evaluating the consequences of having one man as President over another is pretty complicated because of the probable chain of interactions and unintended consequences of policies that may have nothing directly to do with the environment. But, then, isn’t that an incorrect statement? Doesn’t everything we do have an effect on the environment?

Climate change and individual behavior

(Let's open that oven door a little less often.)

Where did this crisis come from? I stand by the 2,500 scientific expert reviewers who signed off on the IPCC 3-volume report in 2007, which was written by more than 800 contributing authors from over 130 countries, and which shared the 2007 Nobel Peace Prize with Al Gore. The report concluded that we have met the enemy and it is us. Realize that about 30 billion tons of CO2 enter the atmosphere each year due to human activities, in addition to vast quantities of sulfur dioxide, nitrous oxide, and methane. It would be astounding to me if that did not have an effect on earth’s climate. But this essay is not going to deal with the issue of whether humans caused the climate change problem, or whether it is due to aliens, or farting cattle, or the most recent Milankovich cycle. I want to focus on our individual behavior.

The carbon cycle is an important one for life on earth. Plants need carbon dioxide, which is given off every time an animal breathes, to conduct photosynthesis, and photosynthesis produces oxygen, which is needed by animals. So there is really a gigantic symbiosis there between those two groups of organisms. Everything went along just fine until the past century. We discovered the fossil fuels of coal, oil, and natural gas, which are comprised mostly of carbon and, of course, when carbon mixes with oxygen we get carbon dioxide. These fossil fuels were safely sequestered hundreds of feet below ground for about 200 million years. We dig them up, bring them to the surface, and burn them, which releases carbon dioxide into the air.

It is a worthwhile exercise to think about how to get rid of all that new carbon now that it is on the surface. Basically, you can not. You can let more plants grow, which sequester carbon in their tissues, but eventually they die and decompose and release the carbon back into the cycle. Much of it falls into the ocean, but it is eventually released again as well. One far-out suggestion is to cut down millions of tons of trees and sink them to the bottom of the ocean, which would take carbon out of the system for centuries. Not recommending that. I don’t have the answer, but we need to keep thinking about how to reduce the carbon that is already out of Pandora’s Box.

But what can we do to reduce the amount of additional carbon we put into the already burdened atmosphere from the package in which it is now sequestered—chunks of coal or barrels of oil? We can reduce the annual flow of CO2 into the atmosphere as individuals. I recently bought two books (can you guess where I bought them?) that have helped me get my head around the companion issues of what are the specific sources of CO2 and what can I do about them. Chris Goodall’s “How to live a low-carbon life: the individual’s guide to stopping climate change” has been the most informative piece I have read yet on this topic. Goodall works for a software company, was a Parliamentary Candidate for the Green Party, and holds an MBA from Harvard. The other book is “You can prevent global warming (and save money!)” by Jeff Langholz and Kelly Turner. Langholz received his Ph.D. in my home department at Cornell, and is now at the Monterrey Institute of International Studies.

Goodall estimates that about half of all CO2 emissions to the atmosphere are due to what individuals do in their daily lives: heat and light their homes, travel, etc. The other half comes from producing the food we eat and shipping it to us from afar, heating and cooling office buildings, and construction. His thesis, which is supported with numerous examples, is that we can not count on the governments of our respective countries (Goodall lives in the UK) to reduce emissions by as much as they are needed. Thus, we need to take responsibility ourselves for reducing our individual contribution from about 12.5 tons of CO2 per person per year to 3 tons per person per year, to use his numbers from the UK. (Remember, you can talk about carbon or you can talk about carbon dioxide, but do not mix the two in an apples to oranges comparison. One ton of carbon equals 3.6667 tons of carbon dioxide).

Goodall does an excellent job at taking each of the “systems” of our lives (e.g., lighting, car travel), explaining the contribution of that component to the overall problem, and offering sound advice on how to minimize our impact. The Langholz and Turner book is like a “saving energy for dummies” guide. What exactly and specifically can you do in your home, and what products are available to do it, to minimize your contribution to the problem of climate change. I find that the two volumes in combination (for a total price of about $25) have armed me for my personal attack on this vexing problem.

So I admit there are actions we can take as individuals, even given my usual pessimism about the quantities involved in these global problems of the environment. Much of it seems to be reprogramming our usual habits. If you want to make a real difference, never fly on a plane, and I mean never. But according to Langholz and Turner, if every oven owner in the U.S. peeked at their dinner cooking one less time per year, we would save 7,000 tons of CO2 from entering the atmosphere every year. For starters, I think I can manage that.

Denial, conspiracy, and the state of the environment

(I just can't figure out where all the oil is going.)

We have all done it. We want to blame someone for nearly everything bad that happens to us. In the case of oil prices, there are several likely suspects. Exxon-Mobil is making huge profits, speculators are driving the price up because of their trading in oil futures, there is too much oil in the U.S. Strategic Petroleum Reserve, and China is hoarding oil.

In fact, a CNBC poll last year during the peak of gasoline prices showed that respondents believed that only 15% of our oil problem was due to consumers; the remaining 85% believed it was due to speculators, OPEC, President Bush, Congress, or big oil companies. It could not possibly be the case that demand exceeds supply, because that would mean that they, or we, or I am using too much oil. If we are using more than can be produced, that might mean that economic growth has a limit of some kind, and that is nothing we have ever had to contemplate.

In fact, we still reject the notion that there is a limit to growth, because, if true, it would adversely affect all types of measures of our “quality of life”: the creation of new jobs, the increase in the value of my stock portfolio, the nation’s GDP, same-store sales this year over last year, and so on. We reject this unpleasant scenario and replace that specter with an attempt to find out who is doing this to us. Once we identify the criminals, we can alert our government who will punish the offenders or pass new legislation and, thereby, fix the problem, or so the thinking goes.

On the other hand, that same week I heard three “experts” on financial markets, all of whom I have come to respect over the past 8 years, come down on the side of basic supply and demand as the fundamental cause of high oil prices---Warren Buffet, Jim Cramer, and Boone Pickens. Pickens, the legendary oil man from Texas, actually said that the world can produce 85 million barrels of oil per day at present, but the global demand is currently 87 million barrels per day. And the International Energy Agency report released earlier that week estimated that by 2030 we will be able to retrieve about 100 million barrels of oil from the ground per day, but the demand then will be about 116 million barrels per day. If the latter number is greater than the former, then there will be demand pressure on the price of oil. Of course, this is not to say that speculation has nothing to do with the exact price of oil at any given moment, but as the adage goes: “Speculation gets the price of a commodity to where it was going anyway, only faster.”

I hear this same conspiratorial sentiment when discussing global climate change with the man in the street. It is all a scam perpetrated by ivory tower scientists and left-wing liberals like Al Gore and weirdo environmentalists. Someone is lying to us because THEY want US to behave differently, so THEY can benefit from our changed behavior. THEY are making up this grand story so THEY can become rich and famous. If THEY were correct that humans are causing climate change and this change is going to be bad for us, then WE would have to do with less, WE might have to curb our growth as a society, WE would have to drive less or drive smaller cars, or WE would have to turn off the lights frequently. THEY are doing something to US!

It should be obvious at this point in this little tirade that I believe as Pogo stated several decades ago: “We have met the enemy and he is us.” There is really no one else to blame for this state of affairs but us: our individual consumption and, likewise, the collective consumption and waste of a huge and growing human population currently numbered at nearly 7 billion. Remember that there is a net annual increase in the human population of about 80 million people per year; a decade ago, the net increase was about 100 million people per year. Currently, that means that every year there are about 100 million new people reaching driving age, regardless of what the driving age is in the country in which they reside. Now, most of those people will probably never drive a car, but I think you get the idea. It is tough to increase the supply of oil, or to reduce the effects of anthropogenic climate change, when the demand is increasing inexorably.

Supplies and prices of commodities or other necessities of life will not be resolved easily or quickly. And neither will global environmental problems like climate change or conservation of biodiversity. But I continue to believe that no problem is likely to be solved unless we understand the true cause. Pogo was a wise opossum.
