Claims that global warming will cause
mass extinction by 2050 were received with uniformly sympathetic
coverage by media outlets. Newspapers in Britain, Canada and the
United States featured stories trumpeting a studys dire warnings
even before its official publication in the journal Nature and well
before any analysis of its merits by the scientific community.
An
expert on global warming, Pat Michaels of the Cato Institute,
states: Obviously, there is a lot to criticize in this paper. What
is surprising is that something with such inconsistencies and
unrealistic assumptions made it unscathed through the review process
in such a prestigious journal as Nature. The studys methodology
can only lead to a reduced number of speciesa growing number of
extinctions[because] climate change is the sole driver of
biodiversity in the calculation made by its authors, Michaels says.
He adds this damning observation: [The authors] calculate
percentage species extinctions for a variety of future climate
scenarios. One, with a lower limit of 0.8 degrees Celsius of warming
in the next 50 years, produces an extinction of roughly 20% of the
sampled species. This results in a convenient Reality Check. Surface
temperatures indeed have risen this amount in the last 100 years;
but there is absolutely NO evidence for massive climate-related
extinctions.
Natures readers may be capable, as Michaels puts
it, of picking that up. The media, however, reach individuals
depending on journalists for sound information with which to judge
the seriousness of the threat. They received commentary like this
by CNNs Hala Gorani on January 8: A study led by a team of
scientists from eight countries has come to the conclusion that one
million species and plants will be extinct from the face of the
earth in the next 50 years because of global warming and rising
temperatures. Apparently even the most catastrophic worst-case
scenario environmentalists probably got it right. That same day
CNNs Sharon Collins announced: The few degrees of temperature rise
predicted for the next 50 years, the study authors believe, could
spell the eventual demise of a million species. Now while theres
some disagreement on how bad the warming will be and how much of it
can be blamed on human influences, most researchers say were in for
big changessome beneficial, some potentially ruinous. There was
not a word in either segment from scientists critical of the
extinction hypothesis, much less the threat of global warming.
Extinction made the front page of January 8ths Washington Post.
The same day the New York Times featured an article by James Gorman
under the headline: Scientists Predict Widespread Extinction by
Global Warming. While noting that one of the papers authors admits
Theres a huge amount of uncertainty, Gorman left readers with
little doubt: Although the results [of the analysis] vary widely,
Dr. [Chris D.] Thomas said, even the most conservative estimates
show that global warming, which he and most scientists attribute to
emissions of carbon dioxide and other greenhouse gases in the
burning of fossil fuels, presents a very serious risk to huge
numbers of species.
Those behind this study are clearly among
the most radical of scientists. As reported by The Independent,
Professor Chris Thomas, a conservation biologist from Leeds
University who led the research team, said only the immediate
switch to green technologies and the active removal of carbon
dioxide from the atmosphere could avert ecological disaster.
The
medias extinction coverage did not advance public understanding
of the scientific realities concerning climate change, but has
served the agenda of those bent on imposing a costly and onerous
political solution to a dubious problem. A responsible media must
provide equal coverage of those arguing that, while there is great
uncertainty regarding global warming, there is no doubt whatever
that the remedy offered by these scientists will have very dire
consequences.
