Energy “will give us serious and sustained problems” over the next 50 years as we make the transition from hydrocarbons — oil, coal, gas — to solar, wind, nuclear and other sources, but we’ll muddle through to a solution to Peak Oil and related challenges. Peak Everything Else will prove more intractable for humanity. Metals, for instance, “are entropy at work . . . from wonderful metal ores to scattered waste,” and scarcity and higher prices “will slowly increase forever,” but if we scrimp and recycle, we can make do for another century before tight constraint kicks in.

Agriculture is more worrisome. Local water shortages will cause “persistent irritation” — wars, famines. Of the three essential macro nutrient fertilizers, nitrogen is relatively plentiful and recoverable, but we’re running out of potassium and phosphorus, finite mined resources that are “necessary for all life.” Canada has large reserves of potash (the source of potassium), which is good news for Americans, but 50 to 75 percent of the known reserves of phosphate (the source of phosphorus) are located in Morocco and the western Sahara. Assuming a 2 percent annual increase in phosphorus consumption, Grantham believes the rest of the world’s reserves won’t last more than 50 years, so he expects “gamesmanship” from the phosphate-rich.

he rates soil erosion as the biggest threat of all. The world’s population could reach 10 billion within half a century — perhaps twice as many human beings as the planet’s overtaxed resources can sustainably support, perhaps six times too many.

most economists see global trade as a win-win proposition, but resource limitation turns it into a win-lose, zero-sum contest. “The faster China grows, the higher grain prices go, the more people in China or India who upgrade to meat, the higher the tendency for Africa to starve,” he said.

Grantham argues that the late-18th-century doomsayer Thomas Malthus pretty much got it right but just had the bad timing to make his predictions about unsustainable population growth on the eve of the hydrocarbon-fueled Industrial Revolution, which “partially removed the barriers to rapid population growth, wealth and scientific progress.” That put off the inevitable for a couple of centuries, but now, ready or not, the age of cheap hydrocarbons is ending. Grantham’s July letter concludes: “We humans have the brains and the means to reach real planetary sustainability. The problem is with us and our focus on short-term growth and profits, which is likely to cause suffering on a vast scale. With foresight and thoughtful planning, this suffering is completely avoidable.”

Grantham, the public face of a company that manages more than $100 billion in assets, the very embodiment of a high-finance insider in blue blazer and yellow tie, has serious doubts about capitalism’s ability to address the biggest problems facing humanity.

When he reminds us that modern capitalism isn’t equipped to handle long-range problems or tragedies of the commons (situations like overfishing or global warming, in which acting rationally in your own self-interest only deepens the harm to all), when he urges us to outgrow our touching faith in the efficiency of markets and boundless human ingenuity, and especially when he says that a wise investor can prosper in the coming hard times, his bad news and its silver lining come with a built-in answer to the skeptical question that Americans traditionally pose to egghead Cassandras: If you’re so smart, how come you’re not rich?
-
Grantham believes that the best approach may be to recast global warming, which depresses crop yields and worsens soil erosion, as a factor contributing to resource depletion. “People are naturally much more responsive to finite resources than they are to climate change,” he said. “Global warming is bad news. Finite resources is investment advice.”
-
“Americans are just about the worst at dealing with long-term problems, down there with Uzbekistan,” he said, “but they respond to a market signal better than almost anyone. They roll the dice bigger and quicker than most.”

“E.D.F. is educating people that dealing with climate change will be good for the economy and job creation. One of Jeremy’s insights is that we can make headway on the market side because higher commodity prices will enforce greater efficiency.”

Grantham says that corporations respond well to this message because they are “persuaded by data,” but American public opinion is harder to move, and contemporary American political culture is practically dataproof. “The politicians are the worst,” he said. “An Indian economist once said to me, ‘We have 28 political parties, and they all think climate change is important.’ ” Whatever the precise number of parties in India, and it depends on how you count, his point was that the U.S. has just two that matter, one that dismisses global warming as a hoax and one that now avoids the subject.

Grantham, who says that “this time it’s different are the four most dangerous words in the English language,” has become a connoisseur of bubbles. His historical study of more than 300 of them shows the same pattern occurring again and again. A bump in sales or some other impressive development causes people to get excited. When they do, the price of that asset class — South Sea company shares, dot-coms — goes up, and human nature and the financial industry conspire to push it higher. People want to hear good news; they tend to be bad with numbers and uncertainty, and to assume that present conditions will persist. In the financial industry, the imperative to minimize career risk produces herd behavior.
-
So it’s news when Grantham, who has built his career on the conviction that peaks and troughs will even out as prices inevitably revert to their historical mean, says that this time it really is different, and not in a good way. In his April letter, “Time to Wake Up: Days of Abundant Resources and Falling Prices Are Over Forever,” he argued that “we are in the midst of one of the giant inflection points in economic history.” The market is “sending us the Mother of all price signals,” warning us that “if we maintain our desperate focus on growth, we will run out of everything and crash.”
-
here’s the short version: “The prices of all important commodities except oil declined for 100 years until 2002, by an average of 70 percent. From 2002 until now, this entire decline was erased by a bigger price surge than occurred during World War II. Statistically, most commodities are now so far away from their former downward trend that it makes it very probable that the old trend has changed — that there is in fact a Paradigm Shift — perhaps the most important economic event since the Industrial Revolution.”
-
When prices go up and stay up, it’s not a bubble. Prices may always revert to the mean, but the mean can change; that’s a paradigm shift. As Grantham tells it, oil went first. For a century it steadily returned to about $16 a barrel in today’s currency, then in 1974 the mean shifted to about $35, and Grantham believes it has recently doubled again. Metals and nearly everything else — coal, corn, palm oil, soybeans, sugar, cotton — appear to be following suit. “From now on, price pressure and shortages of resources will be a permanent feature of our lives,” he argues. “The world is using up its natural resources at an alarming rate, and this has caused a permanent shift in their value. We all need to adjust our behavior to this new environment. It would help if we did it quickly.”

Grantham is taking the Malthusian side in an ongoing debate about growth and commodity prices. The argument often circles back to the bet made in 1980 between the biologist Paul Ehrlich, who foretold catastrophic scarcity caused by overpopulation, and the economist Julian Simon, who argued that any short-term increase in resource prices caused by population growth will stimulate inventors and entrepreneurs to find new ways to exploit those resources, lowering prices in the long run. The two men picked five commodities and wagered on whether their prices, taken as an indicator of scarcity, would be higher or lower in 1990. Simon won, 5-0, even though the world’s population grew by 800 million during that decade. Malthusians have been trying to live down that defeat ever since, but, as Grantham points out in his July letter, if we extend the original bet past its arbitrary 10-year limit to the present day, Ehrlich wins the five-commodity bet 4-1, and he wins big if the bet is further extended to all important commodities.

He’s an impassioned environmentalist not only for the usual reasons but also because he believes humanity’s vexed relationship with the planet is the great economic story of our time. “This commodities thing may turn out to be the most interesting call of my career,” he told me. “I have no doubt we’re going to have a bad hundred years. We have the resources to gracefully handle the transition, but we won’t. We apparently can’t.”

“Whether the stable population will be 1.5 billion or 5 billion,” he said to me, “the question is: How do we get there?”
