Sixty scientists call
on Harper to revisit
the science of global warming
April 15, 2006
An open letter to Canadian Prime Minister Stephen
Dear Prime Minister:
As accredited experts in climate and related scientific
disciplines, we are writing to propose that balanced,
comprehensive public-consultation sessions be held so as to
examine the scientific foundation of the federal government's
climate-change plans. This would be entirely consistent with
your recent commitment to conduct a review of the Kyoto
Protocol. Although many of us made the same suggestion to
then-prime ministers Martin and Chrétien, neither responded,
and, to date, no formal, independent climate-science review has
been conducted in Canada. Much of the billions of dollars
earmarked for implementation of the protocol in Canada will be
squandered, without a proper assessment of recent developments
in climate science.
Observational evidence does not support today's computer
climate models, so there is little reason to trust model
predictions of the future. Yet, this is precisely what the
United Nations did in creating and promoting Kyoto, and still
does in the alarmist forecasts on which Canada's climate
policies are based. Even if the climate models were realistic,
the environmental impact of Canada delaying implementation of
Kyoto or other greenhouse-gas reduction schemes, pending
completion of consultations, would be insignificant. Directing
your government to convene balanced, open hearings as soon as
possible would be a most prudent and responsible course of
While the confident pronouncements of scientifically
unqualified environmental groups may provide for sensational
headlines, they are no basis for mature policy formulation. The
study of global climate change is, as you have said, an
"emerging science," one that is perhaps the most complex ever
tackled. It may be many years yet before we properly understand
the Earth's climate system. Nevertheless, significant advances
have been made since the Protocol was created, many of which are
taking us away from a concern about increasing greenhouse gases.
If, back in the mid-1990s, we knew what we know today about
climate, Kyoto would almost certainly not exist, because we
would have concluded it was not necessary.
We appreciate the difficulty any government has ,formulating
sensible science-based policy, when the loudest voices always
seem to be pushing in the opposite direction. However, by
convening open, unbiased consultations, Canadians will be
permitted to hear from experts on both sides of the debate in
the climate-science community. When the public comes to
understand that there is no "consensus" among climate scientists
about the relative importance of the various causes of global
climate change, the government will be in a far better position
to develop plans that reflect reality, and so benefit both the
environment and the economy.
"Climate change is real" is a meaningless phrase, used
repeatedly by activists to convince the public that a climate
catastrophe is looming, and humanity is the cause. Neither of
these fears is justified. Global climate changes all the time,
due to natural causes, and the human impact still remains
impossible to distinguish from this natural "noise." The new
Canadian government's commitment to reducing air, land, and
water pollution is commendable, but allocating funds to
"stopping climate change" would be irrational. We need to
continue intensive research into the real causes of climate
change, and help our most vulnerable citizens adapt to whatever
nature throws at us next.
We believe the Canadian public and government decision-makers
need and deserve to hear the whole story concerning this very
complex issue. It was only 30 years ago that many of today's
global-warming alarmists were telling us that the world was in
the midst of a global-cooling catastrophe. But, the science
continued to evolve, and still does, even though so many choose
to ignore it, when it does not fit with predetermined political
We hope that you will examine our proposal carefully, and we
stand willing and able to furnish you with more information on
this crucially important topic.
