The Myth of Dangerous Human-Caused Climate Change

Whether dangerous human-caused climate
change is a fact, possibly a fact or a fabrication
depends on who you choose to believe. Many of
us line up somewhere between probable and
possible on this spectrum. (John Roskam,
Australian Financial Review, 2006.)


I have been dismayed over the bogus science and
media hype associated with the (dangerous)
human-induced global warming hypothesis. My
innate sense of how the atmosphere-ocean
functions does not allow me to accept these
scenarios. Observations and theory do not
support these ideas. (Professor Emeritus William
Gray, Colorado State University, 2006.)

Human-caused global warming has become the environmental cause
celebre of the early 21st century. The strong warming alarmist camp
currently includes the United Nations, most Western governments, most
of the free press, many large corporations (including Enron, before it
failed), the major churches, most scientific organisations and a large
portion of general public opinion. This phalanx of support
notwithstanding there is no scientific consensus as to the danger of
human-induced climate change. There is, therefore, a strong conflict
between the level of public alarm and its scientific justification. How can
this be?
In a democracy, the media serve to convey to the public the facts and
hypotheses of climate change as provided by individual scientists,
governmental and international research agencies, and NGO and other
lobby groups. In general, the media have promulgated an alarmist cause
for climate change; they have certainly failed to convey the degree of
uncertainty that is characteristic of climate science, or a balanced
summary of the many essential facts that are relevant to human causation.
Climate change is as much a geological as it is a meteorological issue.
Natural climate changes, both warmings and coolings, are indeed a
societal hazard. We usually deal with geological hazards by providing
civil defence authorities and the public with accurate, evidence-based,
general information about events like earthquakes, volcanic eruptions,
tsunamis and floods, and then by adapting to the effects when a damaging
event occurs. As for other major natural disasters, the appropriate
preparation for extreme climate events is to mitigate and manage the
negative effects when they occur, and especially so for dangerous
coolings. Attempting instead to ‘stop climate change’ by reducing human
carbon dioxide emissions is a costly exercise of utter futility. Rational
climate policies must be based on adaptation to dangerous change as and
when it occurs, and irrespective of its sign or causation.
