A leading U.S. expert withdraws his name from the authorship of a U.N. report on global warming. Other U.S. officials should follow his lead.
Dr. Christopher Landsea, a scientist at the Hurricane Research
Division of the U.S. Department of Commerce and one of the world's
foremost experts on hurricanes, has publicly resigned from
authorship of an upcoming United Nations report on climate change.
Landsea charged that the U.N.'s Intergovernmental Panel on Climate
Change (IPCC) is "both being motivated by pre-conceived agendas and
being scientifically unsound."
He has a point. The IPCC is more of a political body than a
scientific authority. Its members are selected by their respective
governments and approved by the UN Secretariat. This is not an
unbiased, blind process.
Remember those press conferences last fall where esteemed
scientists blamed the severity of the 2004 hurricane season on
global warming? One of them was another federal employee, Kevin
Trenberth. According to Landsea, Trenberth hasn't "performed any
research on hurricane variability." Nonetheless, he is the U.N.'s
designated "Lead Author" for the chapter of the report that
discusses hurricanes and global warming, and as a result would
supervise Landsea's contributions.
According to Landsea, "Given Dr. Trenberth's role as the IPCC's
Lead Author responsible for preparing the text on hurricanes, his
public statements so far outside of current scientific
understanding led me to concern that it would be very difficult for
the IPCC process to proceed objectively with regards to the
assessment on hurricane activity."
Indeed, there is absolutely no evidence that hurricane frequency
or severity has increased because of global warming. In fact, the
only detectable change in Atlantic hurricanes is a decline in
average maximum wind speed, as shown in Landsea's own published
scientific writing.
Trenberth also advocates the position that global warming will
make "El Nino" stronger, with very little scientific evidence. El
Ninos are periodic reversals of Pacific trade winds that change
storm tracks thousands of miles away. They also destroy Atlantic
hurricanes. If global warming actually did make El Ninos more
frequent or stronger, hurricane intensity should decrease.
Landsea appealed to the head of the UN's climate panel, Rajenda
Pachauri, to uphold genuine scientific inquiry.
He should have known better. Pachauri penned the foreword to the
2004 report, "Up in Smoke," distributed by environmental activists
including Greenpeace and the World Wildlife Fund. Referring to
hurricanes, it said "in a world in which global warming is already
happening, such severe weather events are likely to be more
frequent, and extreme."
Pachauri dismissed Landsea's complaint out of hand, which led to
the scientist's principled resignation.
IF ELEMENTS OF THIS story trigger a sense of déjà
vu, then readers have been paying attention. There was a minor
stir last fall when two government scientists predicted a slight (6
percent) increase in hurricane strength over the next century, due
to global warming.
They arrived at this prediction by using a computer model that
assumed carbon dioxide will leach into the atmosphere at a rate
that is twice what has been observed in recent decades. The model
fails miserably when it attempts to forecast hurricanes in the real
world, because it assumes no changes in hurricane environments as
the planet warms. Critical scientists knew about the model's
shortcomings, but they held their peace.
This is becoming a pattern. Scientists, or people claiming the
mantle of science, advance terribly flawed claims that the sky is
falling; climate scientists who understand that this is false say
next to nothing.
Why?
There are several reasons. Just as medical doctors care about
human suffering, environmental scientists are often philosophically
concerned about what they judge to be environmental degradation.
Neither concern is "scientific" in the sense that it is concerned
with testing theories against available evidence, but they do
influence the way scientists behave.
Then there's the money. Climatology used to be very un-cool, and
largely un-funded. It was an impoverished backwater until global
warming came along. Now it's a tremendous sink hole for tax
dollars.
The next federal budget is likely to propose around $4 billion
for research on climate change. That money will only be allocated
if global warming is presented as a severe threat to our health and
well-being on the level of AIDS or cancer. So we end up with
under-funded voices of sanity and a lot of well-funded Chicken
Little-types.
So far, this level of distortion has carried no cost to the
prestige of the dissemblers. The United Nations now passes itself
off as the world's authority on the effects of climate change and
tropical cyclones while keeping a propagandist on as an expert.
Perhaps President Bush, who ultimately must approve U.S. members
for the panel, should approve none, effectively withdrawing his
government from this pseudoscientific charade.
