First, what is this effect? Ever since the Industrial Revolution began in the 18th century,
smoke from fossil fuels, oil, natural gas and especially coal has deposited carbon dioxide in
the lower part of the earth's upper atmosphere. The effect of this has been that part of the
energy of the sun's rays reflected from the earth's surface has been absorbed by the CO2
and by water vapor and returned to the earth in the form of heat. Thus the atmosphere is
behaving increasingly like a greenhouse. The glass allows the sunlight through but traps the
heat. The consequence is what is called global warming.

There is a school of thought which says that the result will be a change in the earth's
climate, plus an increase in nitrous oxide, methane gas and FREONS. It is predicted that by
the mid-21st century, average temperatures will rise by 5 degrees C (9 degrees F). This will
result in the melting of glaciers and the polar ice-caps. Coastal waters will rise and inundate
many low-lying countries. Food production for an increasing world population will be put at

Not everyone, of course, accepts this scenario, though the quantity of CO2 in the lower
upper-atmosphere is constantly monitored, and the fact that the level is increasing is not
disputed. Whether or not the expected rise in average temperature will happen is another
matter. There have been no significant climatic changes for centuries, indeed millennia and,
the opponents of the doom-merchants argue, nature has its own methods of damage-
limitation and self-adjustment. Moreover, there are no present signs of global warming. The
weather patter in Britain, for example, is much the same as it was in Victorian days, or
Roman days for that matter. Why should it suddenly change? Coal has always been burnt
and before coal, wood and charcoal. Forest fires have always raged. Volcanoes, and
explosions such as Krakatoa (1883) have always thrown tons of noxious gases into the
atmosphere. After that particular explosion, a cloud of dust and gas drifted over Europe and
darkened the sun for six months - before dispersing naturally. A tidal wave drowned 36,000
in the Java-Sumatra area. Nature's self-damage greatly exceeds any possible human

The fact is, however, that many people do take the greenhouse threat seriously, and there is
a cross-section of people in most industrialized countries who lobby continuously against
the continued use of fossil fuels. Whether they are right, or merely alarmist, only time will
tell. However, the fact that CO2 is on the increase is undisputed. Further, it cannot be
disputed that the greenhouse effect is a possibility, even if remote. Nuclear war is also a
possibility, though remote, but every possible step is taken by democratic countries to
ensure that it will not happen. So, therefore, should every possible step be taken to reduce,
even eliminate CO2 emissions. There are already agreements in the USA and in Europe to
cut down, or eliminate the use of fossil fuels by certain target dates.

The problem is that many countries are geared to fossil rather than nuclear power sources.
Supplies of coal, and probably of oil and natural gas, are virtually unlimited. In Britain, most
pits have closed down, causing wide-spread unemployment and much consequent human
suffering. The coal lobby argues for emission cleansing and a compromise, both economic
and environmental, may be possible. It would be cheaper, they argue, than to transfer
entirely to nuclear power, whose installations may in any event cause health hazards and
even the occasional disaster.

One optimistic sign is that proponents of all power sources agree that every generation has
an obligation to preserve rather than exploit and pollute the planet. The worst culprits in
the CO2 saga are the old-fashioned heavy industry plants, such as those in the Ruhr, East
Germany, and what was the Soviet Union, and the fossil-fuel fired electricity-generating
stations. Much of the old industrial plant has now been either modernized or superseded,
and some countries such as France have moved over almost entirely to nuclear power. That,
in my opinion, is the way forward.

I do not believe that in any event, the greenhouse effect would have the dire consequences
which have been predicted. Yet, it is a risk which we should not take. Modern technology
has outgrown the use of fossil fuels, and apart from any possible dangers to future
generations, the kind of world to which we commit them should be a clean, wholesome and
beautiful world, as the Creator intended.
