Global warming, its dangers for the planet and the reasons for it,
has become something of a sacred cause for many environmental
activists and some in the scientific community. However, the case
that these advocates make for urgent action is often over-stated and
flawed in the evidence that is presented. The situation is much less
clear-cut than these zealots would claim. There may well be a case
for accepting that the earth is warming, but even that is not a total
certainty. At any rate, it must be remembered that the earth has
always undergone climactic change independent of human
interventions.
Extravagant claims were being made only a few years ago that
within fifty years time, the average temperature of the globe would
rise by an average of ten degrees. These wildly apocalyptic
forecasts were being made by scientists and activists who stated
that widespread ecological disaster awaited the planet and this was
largely due to the impact of human behaviour through carbon
emissions, the swallowing up of the earth’s natural resources and
pollution in general. This simply has not happened and those
forecasts can now be seen as simply alarmist. Now it is generally
agreed that those wild forecasts of doom were wholly exaggerated
and that the effect of global warming, if it is to happen, would be
far less drastic than was previously thought.
If those dire prognostications were false, what can be trusted in the
current propaganda circulated through the media by those with a
particular ecological axe to grind? The scientific evidence for
global warming is, at best, contradictory. There have been many
dissenting voices in the scientific community who doubt the very
basis of the ecologist argument. Professor Otis Jones of Duke
University, Illinois, for example, has claimed that the panic over
global warming has been politically motivated. Yes, other scientists
say, there may well be a process of global warming taking place,
but the extent of it is much less dramatic that has been described
hitherto. Perhaps some ice caps are melting, these scientists argue,
but at such a slow rate that the planet is in no real danger. Yes,
