Is
there anyone out there that still thinks that there's still something
that can be expected from the political masters (except insanity and
lies) or that Obama is on your side?!
I'm critical of the IPCC, but.....
The
House Science Committee Declares The IPCC Report Is Not Science
IO9,
30
May, 2014
The
Intergovernmental Panel on Climate Change (IPCC) report warned
that more intense droughts and heat waves will cause famine and water
shortages. But, don't worry! Yesterday, the GOP held a hearing to
tell us the IPCC is, in fact, a
global conspiracy to control our
lives and "redistribute wealth among nations."
The
hearing,
titled "Examining the UN Intergovernmental Panel on Climate
Change Process," was convened by the House Committee on Science,
Space and Technology—the same folks who recently demonstrated their
inability
to grasp the idea that the world's climate varies across different
regions
and who informed us that warmer weather didn't bother the dinosaurs,
so what's all the fuss about?
I've
seen some surreal moments in our nation's capitol, but few can
compare to watching…
In
principle, there's nothing wrong with assessing the methodology of
such an important and influential report. But, in one of those
quintessential moments of Washington double-think, Chairman Lamar
Smith (R-TX)—who accuses the IPCC of creating data to serve a
predetermined political agenda—summarized the hearing's conclusions
a day before it even began. "The IPCC does not perform science
itself and doesn't monitor the climate," Smith told
a reporter, "but only reviews carefully selected scientific
literature."
So,
small wonder that Rep. Eddie Bernice Johnson (D-TX), the ranking
Democrat on the committee, offered the
opinion:
While
the topic of today's hearing is a legitimate one, namely, how the
IPCC process can be improved, I am concerned that the real objective
of this hearing is to try to undercut the IPCC and to cast doubt on
the validity of climate change research.
We
aren't going to get very far if we spend our time continually
revisiting a scientific debate that has already been settled. Nor
will we get far if we continue a recent practice on this Committee of
seeming to question the trustworthiness and integrity of this
nation's scientific researchers.
Fair
and Balanced
Another
source of Johnson's skepticism might have been that three of the four
expert witnesses testifying at the hearing either deny that humans
are responsible for global warming or believe that the potential
impact of climate change is grossly overstated
SEXPAND
The
witnesses for the prosecution were:
(1)
Roger Pielke,Sr.
Who
is he?
Senior
Research Scientist, Cooperative Institute for Research in
Environmental Sciences, and Professor Emeritus of Atmospheric
Science, Colorado State University
What's
he known for?
Pielke
says that carbon dioxide is responsible, at most, for about 28% of
human-caused warming up to the present and he is among
the
most vocal
skeptics
of reports that the polar ice caps are melting and that sea levels
are rising.
What
did he say at the hearing?
The
IPCC is "giving decision makers who face decisions at the
regional and local level a false sense of certainty about the
unfolding climate future."
(2)
Richard Tol
Who
is he?
A
professor of economics at the University of Sussex
What's
he known for?
He
resigned his position with the IPCC team producing the working
group's Summary for Policymakers, which he classified as "alarmist."
Global warming creates benefits as well as harms, he believes,
and in the short term, the benefits are especially pronounced. He's
also expressed
doubt
that climate change will play any role in exacerbating conflicts.
Tol
has been criticized by other scientists who have raised questions
about his methodology and who have noted that he has a history of
making contradictory statements. For instance, in a widely cited 2009
paper, he wrote
of "considerable uncertainty about the economic impact of
climate change … negative surprises are more likely than positive
ones. … The policy implication is that reduction of greenhouse gas
emissions should err on the ambitious side."
What
did he say at the hearing?
"Academics
who research climate change out of curiosity but find less than
alarming things are ignored, unless they rise to prominence in which
case they are harassed and smeared….The IPCC should therefore
investigate the attitudes of its authors and their academic
performance and make sure that, in the future, they are more
representative of their peers."

Daniel Botkin
Who
is he?
Professor
Emeritus, Department of Ecology, Evolution, and Marine Biology,
University of California, Santa Barbara.
What's
he known for?
He
has long argued that life has had to deal with environmental change,
especially climate change, since the beginning of its existence on
Earth—and that we underestimate the ability of species, including
humans, to find ways to adapt to the problem.
Botkin
wrote a controversial editorial for the Wall
Street Journal
(Oct 17, 2007) arguing that global warming will not have much impact
on life on Earth, and noted that: "the reality is that almost
none of the millions of species have disappeared during the past 2.5
million years — with all of its various warming and cooling
periods."
For
the past 2.5 million years the climate has oscillated between
interglacials which were (at most) a little warmer than today and
glacials which were considerably colder than today. There is no
precedent in the past 2.5 million years for so much warming so fast.
The ecosystem has had 2.5 million years to adapt to
glacial-interglacial swings, but we are asking it to adapt to a
completely new climate in just a few centuries. The past is not a
very good analog for the future in this case. And anyway, the human
species can suffer quite a bit before we start talking extinction.
What
did he say at the hearing?
"I
want to state up front that we have been living through a warming
trend driven by a variety of influences. However, it is my view that
this is not unusual, and contrary to the characterizations by the
IPCC….these environmental changes are not apocalyptic nor
irreversible…..Yes, we have been living through a warming trend, no
doubt about that. The rate of change we are experiencing is also not
unprecedented, and the "mystery" of the warming "plateau"
simply indicates the inherent complexity of our global biosphere.
Change is normal, life on Earth is inherently risky; it always has
been."
The
Q & A
The
lone witness for the defense was Michael Oppenheimer, the Albert G.
Milbank Professor of Geosciences and International Affairs at
Princeton University. He was selected by the Democrats, "because
he's one of the foremost experts in the world and has been involved
with the IPCC," a spokesperson for the Democratic contingent of
the committee told Motherboard
reporter Jason Koebler.
For
two hours, climate change deniers interrupted, berated, and cut off
Oppenheimer, while the other three other witnesses fielded softball
questions from conservative lawmakers and dodged tougher ones from
Democratic ones.
In
fact, at one point, Rep. Larry Buchson (R-Ind.), who, seconds before
had interrupted Oppenheimer and said he wasn't interested in hearing
his views, wanted to "apologize on behalf of Congress" to
Pielke for the aforementioned "juvenile and insulting questions
trying to disparage the credibility" of witnesses who didn't
take climate change seriously…..
Dana
Rohrabacher [R-CA] pulled out the air quotes when he said "global
warming," and took offense to Oppenheimer not being able to
"capsulize" all the reasons why he believes that climate
change is a big deal in 10 seconds. Smith suggested that the "only
thing we know about [climate change models] is that they will be
wrong" and suggested that "even if the US was completely
eliminated, it's not going to have any discernible impact on global
temperatures in the near or far future."
Paul
Broun [R-GA] and Buchson noted their belief in the "scientific
process" and suggested that they knew more about it because they
are doctors (Broun is a dentist; Buchson is a surgeon).
So
predictable, and such a waste of time. As I noted earlier, in
principle, there is nothing wrong with assessing the methodology of
such an important and influential report. But there are far better
ways to do it than this.
SEXPAND
The
most noteworthy aspect of the IPCC is that it has worked far better
than anyone anticipated. As Spencer Weart, the former director of the
Center for History of Physics has written:
The
IPCC's constitution should have been (and perhaps was intended to be)
a recipe for paralysis. Instead, the panel turned its procedural
restraints into a virtue: whatever it did manage to say would have
unimpeachable authority.
Experts
contributed their time as volunteers, writing working papers that
drew on the latest studies. These were debated at length in
correspondence and workshops. The IPCC scientists, initially 170 of
them in a dozen workshops, worked hard and long to craft statements
that nobody could fault on scientific grounds. The draft reports next
went through a process of peer review, gathering comments from
virtually every climate expert in the world. It was much like the
process of reviewing articles submitted to a scientific journal,
although with far more reviewers. All this followed the
long-established practices, norms and traditions of science. The
scientists found it easier than they had expected to reach a
consensus. This undertaking was the first of its kind in terms of
breadth, and the exhaustive level of review and revision.
If
Congress only worked half as well.
On behalf of conscientious Americans, I offer sincere apologies to the citizens of the rest of the world.
