Seven Big Failed Environmentalist Predictions

I recently discussed what it would take to prove that global warming is actually occurring, that it is caused by humans, and that it will be catastrophic. But that’s not the full picture. To understand why so many of us are so skeptical about global warming, you have to understand the environmentalists’ larger track record: a long series of failed predictions and bogus prognostications of doom.

It has been 45 years now since the first Earth Day. You would think that in this time frame, given the urgency with which we were told we had to confront the supposed threats to the environment—Harvard biologist George Wald told us, “Civilization will end within 15 or 30 years unless immediate action is taken”—at least one of the big environmental disasters should have come to fruition. Fifteen years ago, an article in Reason took a look at claims like this from the first Earth Day in 1970. The specific quotations have been helpfully excerpted here and have been bounced around a lot on the Internet and on conservative talk radio for the last few days. It is a comical litany of forecasting gone wrong. […]

1) Global Cooling

A list like this has to start with the “climate change” catastrophe the environmentalists were all warning about in the 1970s: global cooling and a descent into a new ice age. Personally, I’m on record predicting another ice age—sometime in the next 10,000 years or so—based on the geological record, which indicates that the Earth goes through natural glacial and interglacial cycles. We’re in a warm period now, which is very good for us, but we can expect this will eventually change and Canada (if it still exists) will someday be in danger of being scraped off the Earth by the advancing ice sheets.

But the claim in the 1970s was different. We were causing the ice age and bringing the glaciers down on our own heads. Deforestation was going to increase the reflectivity of the Earth’s surface, causing light from the sun to bounce back into space without heating the Earth. Meanwhile, emissions of “particulates,” i.e., smoke from industrial smokestacks, was going to block out the light before it even got here. No, really: Life Magazine in 1970 reported that “by 1985 air pollution will have reduced the amount of sunlight reaching earth by one half.” That’s funny, I recall the mid-1980s, and the future was so bright, we had to wear shades.

But they didn’t just have a proposed physical mechanism for this catastrophe. They had the evidence of the temperature record, which showed global temperatures generally declining from about 1940 to 1970. Which led to fevered predictions like this one, from UC Davis ecology professor Kenneth Watt: “The world has been chilling sharply for about twenty years. If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but eleven degrees colder in the year 2000. This is about twice what it would take to put us into an ice age.”

As late as 1980, Carl Sagan was still presenting global cooling as one of two possible doomsday scenarios we could choose from.

When global temperatures began to rise, the alarmists switched to the other scenario. The one thing they didn’t change was the assumption that industrial civilization must somehow be destroying the whole planet. […]

2) Overpopulation

When environmentalists said that we were destroying the Earth, they meant it directly and literally. The biggest problem was the very existence of humans, the fact that there were just too darned many of us. We were going to keep growing unchecked, and we were going to swarm the surface of the Earth like locusts, destroying everything in our path until we eventually used it all up.

There were going to be an inconceivable seven billion people on Earth by the year 2000, and there was just no way we could support them all. Well. […]

3) Mass Starvation

Predictions of global famine were part of the population growth hysteria, but they were such a big part that they deserve their own separate treatment.

My favorite failed prediction is this one, from Peter Gunter, a professor at North Texas State University, in a 1970 issue of The Living Wilderness.

Demographers agree almost unanimously on the following grim timetable: by 1975 widespread famines will begin in India; these will spread by 1990 to include all of India, Pakistan, China and the Near East, Africa. By the year 2000, or conceivably sooner, South and Central America will exist under famine conditions…. By the year 2000, thirty years from now, the entire world, with the exception of Western Europe, North America, and Australia, will be in famine.

I love the part about how “demographers agree almost unanimously.” Sound familiar? I don’t know whether that was really true in 1970, but if they did, they were almost unanimously wrong. […]

4) Resource Depletion

In addition to running out of food, we were also supposed to run out of natural resources, such as nickel and copper, and above all we were running out of oil.

Here’s our friend Kenneth Watt again, with his present trends continuing: “By the year 2000, if present trends continue, we will be using up crude oil at such a rate…that there won’t be any more crude oil. You’ll drive up to the pump and say, ‘Fill ‘er up, buddy,’ and he’ll say, ‘I am very sorry, there isn’t any.’”

The quaintest thing about this quote, of course, is that he thought there would still be “full-service” gas stations where a guy was standing there ready to pump your gas.

None of these predictions came true. The economist Julian Simon famously made a bet with Paul Ehrlich about whether the prices of five key metals. “nickel, copper, chromium, tin, and tungsten,” would decline over the next ten years, as Simon predicted, or whether prices would rise as supplies ran out, according to Ehrlich’s theory. Ehrlich lost the bet, badly, and would do so over practically any long time period. […]

5) Mass Extinction

At the first Earth Day, its political sponsor, Senator Gaylord Nelson, warned: “Dr. S. Dillon Ripley, secretary of the Smithsonian Institute, believes that in 25 years, somewhere between 75 and 80 percent of all the species of living animals will be extinct.”

To put that in perspective, a 75% to 80% mass extinction is on the level of the cataclysm that killed the dinosaurs 66 million years ago—caused by the “environmental” catastrophe of a six-mile-wide meteor crashing into the Earth and cloaking it in an enormous cloud of ash  and dust. Obviously, nothing remotely like that happened between 1970 and 1995.

There are still those who are peddling the notion that we’re in the process of the Sixth Great Extinction. So it didn’t happen back when they first said it would, but it’s going to happen soon, any day now

Some cold water was just thrown on this theory from an unexpected source: Stewart Brand, founder of the Whole Earth Catalog, writes:

Many now assume that we are in the midst of a human-caused “Sixth Mass Extinction” to rival the one that killed off the dinosaurs 66 million years ago. But we’re not. The five historic mass extinctions eliminated 70 per cent or more of all species in a relatively short time. That is not going on now. […]

6) Renewable Energy

This isn’t a prediction about a disaster that didn’t happen. It’s a prediction about a solution that never materialized. Don’t worry about the fact that we want to shut down fossil fuels and dirty coal, we were told, because there’s a bright new future from “Renewable Energy.”

But all of the alternatives we were promised fall into two categories. There are those that are still too unreliable and expensive; Germany is about to be crushed by the massive cost of its renewable energy boondoggle. And then there are those which have gone from being the alternative championed by environmentalists to being the targets of the environmentalist anger. This is by far the most common trajectory.

You know how old I am? I’m so positively ancient that I remember when one of Jimmy Carter’s big answers to the impending shortage of oil was to increase federal funding for research on how to extract oil from shale. It ended the way you would expect: it went nowhere. But some decades later, private oil companies did find a way to more economically extract oil from shale—and environmentalists promptly made it public enemy #1.

I am even old enough to vaguely remember the era when nuclear energy—that bête noire of the greens—was touted as an alternative to fossil fuels. Or when hydroelectric dams were celebrated as an emissions-free, radiation-free, feel-good source of electricity, rather than a fish-killer and impediment to the free flow of wild rivers. Or when wind farms were the future of energy, before they were denounced as bird-killers and a blight on the landscape. Now, even large-scale solar energy is under attack. And I’m still waiting for environmentalists to figure out exactly what goes in to those solar panels. […]

7) Global Warming

Which brings us back to global warming. I noted last week that after a multi-decade plateau in global temperatures, they are now at or below the low end of the range for all of the computer models that predicted global warming.

If we go full circle, back to the failed prediction of global cooling, we can see the wider trend. After two or three decades of cooling temperatures, from the 1940s to 1970, environmentalists project a cooling trend—only to have the climate change on them. After a few decades of warmer temperatures, from the 1970s to the late 1990s, they all jumped onto the bandwagon of projecting a continued warming trend—and the darned climate changed again, staying roughly flat since about 1998.

No wonder all of these environmental hysterias seem to begin with the phrase, “if current trends continue.” But current trends don’t continue. Global temperatures go down, then up, then stay flat. Population growth tapers off, while agricultural yields increase at even higher rates. We don’t just sit around using up our currently available oil reserves; we go out and find new reserves of oil and new ways to extract it.

And that’s the real issue. The environmental doomsayers don’t just extrapolate blindly from current trends. They extrapolate only from the trends that fit their apocalyptic vision while ignoring trends that don’t fit. They project forward the current rate at which we’re using up our resources, but ignore the history of our ability to innovate and create. They get all excited by 20 years of rising temperature or rising oil prices—but ignore two centuries of rising wealth and longevity.
