The Cooling World

There are ominous signs that the Earth’s weather patterns have begun
to change dramatically and that these changes may portend a drastic
decline in food production – with serious political implications for
just about every nation on Earth. The drop in food output could
begin quite soon, perhaps only 10 years from now. The regions
destined to feel its impact are the great wheat-producing lands of
Canada and the U.S.S.R. in the North, along with a number of
marginally self-sufficient tropical areas – parts of India,
Pakistan, Bangladesh, Indochina and Indonesia – where the growing
season is dependent upon the rains brought by the monsoon.
The evidence in support of these predictions has now begun to
accumulate so massively that meteorologists are hard-pressed to keep
up with it. In England, farmers have seen their growing season
decline by about two weeks since 1950, with a resultant overall loss
in grain production estimated at up to 100,000 tons annually. During
the same time, the average temperature around the equator has risen
by a fraction of a degree – a fraction that in some areas can mean
drought and desolation. Last April, in the most devastating outbreak
of tornadoes ever recorded, 148 twisters killed more than 300 people
and caused half a billion dollars’ worth of damage in 13 U.S.
states.
To scientists, these seemingly disparate incidents represent the
advance signs of fundamental changes in the world’s weather. The
central fact is that after three quarters of a century of
extraordinarily mild conditions, the earth’s climate seems to be
cooling down. Meteorologists disagree about the cause and extent of
the cooling trend, as well as over its specific impact on local
weather conditions. But they are almost unanimous in the view that
the trend will reduce agricultural productivity for the rest of the
century. If the climatic change is as profound as some of the
pessimists fear, the resulting famines could be catastrophic. “A
major climatic change would force economic and social adjustments on
a worldwide scale,” warns a recent report by the National Academy of
Sciences
