A Truth Still Too Inconvenient for Al Gore

A nice man, a lovely family, and an inconvenient truth.


Ten years ago, I went to see "An Inconvenient Truth," Al Gore's global warming documentary.

I found the movie extremely well done and not boring.  I recommended the movie, noting that "it is certainly better than most of the pap offered up on the Silver Screen."

Having just given the movie "two thumbs up," however, I noted that there were a few "inconvenient truths" that Al Gore has left out of his documentary.

At the beginning of the movie, Al Gore tells us he has been following global warming issues since he was in college. Me too, and oddly enough for the same reason.

Al Gore was a student of Roger Revelle's at Harvard. It was Revelle who designed some of the first experiments and theories underpinning the nascent science of global climate change.

It so happens that my father was head of the climatology program for the American Association for the Advancement of Science back in the late 1970s and early 1980s, and worked closely with Revelle. In fact, I think my father may have written the first New York Times editorial ever written on global warming.

When Al Gore first met Roger Revelle back in 1966, Revelle was Director of the Center for Population Studies at Harvard -- a position he held from 1964 to 1976.

Gore manages to tell us quite a bit about Roger Revelle and his own youthful conversion to environmental causes without ever mentioning Revelle's demographic concerns, or the size of the Gore nuclear family.

In fact, I would argue this is not an accident. Population growth is an "inconvenient truth" -- the one that underpins global warming, and one that is particularly inconvenient for Al Gore as he tells us his global warming jeremiad.

You see, Al Gore has four children. Think about that for a minute.

If the average woman in the world followed Al Gore's lead, the population of the world would double every 25 years -- FOREVER.

Al and Tipper Gore chose to have more children than the average woman is having today in India, China, Zimbabwe, South Africa, El Salvador, Jamaica, Indonesia, Bangladesh, Vietnam or the Philippines -- to randomly pick from a few of the less developed countries from around the globe.

Al Gore had a choice to make when it came to having a family. He could have had no children. Or one child. He could have chosen to stop at two. He could have built his family through adoption or stopped at three kids. Instead, Al and Tipper Gore chose to double the human load they put on this planet.

It's not like Al and Tipper did not have access to health care and a diverse array of family planning options. Al and Tipper had more information about, and better access to, contraception than almost anyone else on the planet.

It's not like Al and Tipper Gore did not know better. Al and Tipper were married in 1970, at a time when Paul Ehrlich's book "The Population Bomb" was a national best seller, and when the speed of both world and U.S. population growth were core messages of the first Earth Day.

And yet Al Gore ignored it all. Al and Tipper had their first child in 1973, their second in 1977, their third in 1979, their fourth in 1982.

Let's put this story in numerical context. When Al Gore was listening to Roger Revelle at Harvard in 1966, the population of the world was 3 billion. Today it is over 6.2 billion people, and it will be over 12 billion by 2033 if the world follows the Gore model for family planning.

Gore's discussion of global warming shies away from causation. It is an odd but true fact that this very smart man has made an entire movie about global warming and greenhouse gases without once saying where those gases come from.

There's a reason for that. The inconvenient truth is that the world is NOT producing more greenhouse gases per person than it did in 1830 when the world had 1 billion people. Nor is it producing more greenhouses gases per capita than it did in 1930 when the world had 2 billion people.

The inconvenient truth is that the world is producing about the same or less greenhouses gases per person today that it did 50 or 100 years ago. People forget that horses produced serious amounts of greenhouse gases (methane) and so too did homes heated with wood and coal.



Table 1, page 19 from "Per Capita Carbon Dioxide Emissions Convergence or Divergence?" by Joseph E. Aldy, 2005 published by Resources for the Future (PDF)



The simple fact is that while the atmospheric level of CO2 has increased 30 percent since 1860, world population has more than quadrupled since then. Per capita CO2 emissions in the industrialized world are actually in decline, and have been for quite some time. When we look at all CO2 production, we find that global population growth and CO2 emissions track almost perfectly.

The problem is not that we are driving cars or cooling our beer in refrigerators -- it's that there are too many people. Too many people necessarily results in too many cars, too many refrigerators, and too many coal-fired electrical plants.

There are too damn many of us!





Population growth, energy use and CO2 emissions track perfectly. The causal agent here is human population growth -- an "inconvenient truth" largely glossed over in Al Gore's otherwise excellent movie. Figure 2 is from "Atmospheric Carbon Dioxide as a proxy for growth of the human population? ," 1995, University of Washington



Al Gore is willing to talk about rebuilding power plants, building nuclear reactors, knocking down or retro-fitting every building on the planet. He is willing to discuss what's wrong with Ford and Chevy, but he is not willing to talk too long or too loudly about population growth for fear his audience might look over his shoulder to see how many people are sitting in his own family room.

Like most people, Al Gore is more comfortable talking about CO2 emissions than he is about IUD's. He would rather talk about the need for a new type of internal combustion engine than about the need for internal self-restraint, birth control pills, and vasectomies. He would rather count carbon molecules than count human noses.

In this sense, Gore (like most politicians) is part of the problem.

A politician is always willing to invest a few billion dollars to subsidize energy research at the local university, or pump a few billion dollars into a program to subsidize new car designs by General Motors. But talk about cutting back on immigration (which is driving nearly 100 percent of U.S. population growth), or pumping a billion dollars a year into Third World contraception programs and .... well, there are a thousand and one excuses to do little or nothing. To be fair, those excuses come from both sides of the political aisle. While people may be the source of greenhouse gas emissions, they are also the fuel of politicians, political parties and corporate sponsors.

And so, in the end, we have a movie about global warming that does not really talk about what causes global warming. How ironic is that?

Al Gore's global warming movie concludes by telling us to turn down the thermostat and to send more letters to Congress. It tells us to ride bicycles and use public transportation. It tells us to use more energy-efficient light bulbs and bring more people to the Al Gore movie.

But it does not tell us to have fewer children.

It does not remind us that an open-border immigration policy in this country has global resource consequences in the form of more greenhouse gases, more energy use, and more pollution.

Al Gore's slide show does not suggest contraception, immigration law enforcement, and communitarian self-restraint, nor does it point out that the science of reproduction is widely understood and that improved access to contraception is extremely popular across all cultures and religions. (Did you know that Catholic countries have the lowest fertility rates in the world? The abortion is legal in Italy? That Iran has below-replacement fertility? Did you know that the U.S. has the fastest population growth rate in the developed world?)

The end result is that Al Gore's movie on global warming offers us little more than hot-air solutions.

The inconvenient truth is that immigration-fueled population growth in the United States is negating every single energy conservation effort we are making in this nation today, and that population growth across the globe is negating every single energy conservation effort being made in the world today.

That's a message you won't hear at the local Multiplex or in too many discussions about "An Incovenient Truth" 10 years on.

It's a message that's still a little too "inconvenient."
