Climate-change alarmists warn us about coming food shortages. They said the
same in 1968.
Warming is becoming a major problem. "A change in our climate,"
writes one deservedly famous American naturalist, "is taking place very
sensibly." Snowfall, he notes, has become "less frequent and less
deep." Rivers that once "seldom failed to freeze over in the course
of the winter, scarcely ever do so now."
And it's having an especially worrisome effect on the food supply:
"This change has produced an unfortunate fluctuation between heat and
cold, in the spring of the year, which is very fatal to fruits."
That isn't a leaked excerpt from the latest report of the U.N.'s
Intergovernmental Panel on Climate Change, but it may as well be. Last week,
Canadian journalist Donna Laframboise of the website No Frakking Consensus
posted a draft of a forthcoming IPCC report on the alleged effects climate
change will have on food production. The New York Times then
splashed the news on its front page Saturday. It's another tale of warming woe:
"With or without adaptation," the report warns, "climate
change will reduce median yields by 0 to 2% per decade for the rest of the
century, as compared to a baseline without climate change. These projected
impacts will occur in the context of rising crop demand, projected to increase
by 14% per decade until 2050."
If this has a familiar ring, it's because it harks back to the
neo-Malthusian forecasts of the 1960s and '70s, when we were supposed to
believe that population growth would outstrip food production. This gave us
such titles as "Famine 1975!", a 1967 best seller by the brothers
William and Paul Paddock, along with Paul Ehrlich's vastly influential
"The Population Bomb," a book that began with the words, "The
battle to feed all of humanity is over. In the 1970s and 1980s hundreds of
millions of people will starve to death in spite of any crash programs embarked
upon now."
In case you're wondering what happened with that battle to feed humanity,
the U.N.'s Food and Agriculture Organization has some useful figures on its
website. In 1968, the year Mr. Ehrlich's book first appeared, Asia produced
46,321,114 tons of maize and 439,579,934 of cereals. By 2011, the respective
figures had risen to 270,316,205, up 484%, and 1,289,633,254, up 193%.
It's the same story nearly everywhere else one looks. In Africa, maize production
was up 247% between 1968 and 2011, while production of so-called primary
vegetables has risen 319%; in South America, it's 308% and 199%. Meanwhile, the
world's population rose to just under seven billion from about 3.7 billion, an
increase of about 90%. It is predicted to rise by another 33% by 2050.
But what about the supposedly warming climate? According to the EPA,
"average temperatures have risen more quickly since the late 1970s,"
with the contiguous 48 states warming "faster than the global rate."
Yet U.S. food production over the same time has also risen by robust
percentages even as the number of acres under cultivation has been steadily
falling for decades.
