2. International Seminar On Climate Change Puts Fears To Rest
Russian Academy of Sciences - Moscow 5-8 July 2004
The Russian Academy of Sciences (RAS) invited an International Team to
provide balance and counter claims by a British Team led by Sir David
King (the UK Govt's Chief Scientific Adviser) and Sir John Houghton (former
Director General of the UK Met Office). The RAS had already concluded
that 'There is no scientific basis for the Kyoto Protocol'.
As reported by invited scientist Piers Corbyn (London), the British Government
Team, after failing to prevent the international science team - of which
Corbyn was part - from speaking, resorted to spoiling tactics because
they were unable to answer questions. They subsequently tried to portray
the event as somehow 'taken over' by others/Russians.
KEY POINTS from the International Seminar
1. World Temperatures do not follow CO2 levels and indeed the warmest
periods in the last 2,000 years were the Roman period and the Medieval
period which were both warmer than present and had lower CO2 levels {various
speakers - William Kininmonth Australian Climate Research}.
2. Solar particles decisively affect World temperatures.
There is a much better correlation between world temperatures and particles
than with CO2 levels {Piers Corbyn, Weather Action, London}.
3. There is no significant Sea level rise - in particular the Maldives
are in no danger of submergence {Prof Nils-Axel Morner, Stockholm University}.
4. There is no climate induced increased danger of tropical diseases,
e.g. malaria, since it is not itself a tropical disease - having being
prevalent in Russia and Britain at various times. {Paul Reiter, Pasteur
Institute Paris}.
5. There is no discernible link between Global warming & Extreme weather.
Indeed the British Govt delegation specifically said they did not claim
any increase in storms due to man-made CO2. {Madhav L Khandekar, consulting
meteorologist, Ontario, Canada}.

3. Narrowing the Value of Climate Sensitivity
SFS/ 8/19/2004
Letter to The Industrial Physicist
Climate sensitivity is defined as the (equilibrium) global-mean temperature
increase from a doubling of GH-gas forcing. It was first set in 1979 by
"hand-waving" [1] as between 1.5 and 4.5 degC and has since
appeared - unchanged -- in every IPCC Assessment Report, from 1990 to
2001. The large range, a factor of three, is an indication of the uncertainty
inherent in climate models because of different assumptions, parameterizations,
and approximations in trying to simulate complicated atmospheric processes.
It is important to narrow this range and to validate model results by
comparing with actual observations.
In a UN-IPCC Workshop on Climate Sensitivity held in Paris, 26-29 July
2004, 14 models gave values of from 2.0 to 5.1 degC [1]. But after polling
eight current models, Gerald Meehl (NCAR) narrowed the range to 2.6 to
4.0, remarkably close to that derived from an MIT model [2]. But this
apparent agreement does not constitute validation against observations
- the only real test.
For example, James Murphy et al (Hadley Centre, UK), got a range of 2.4
to 5.4 degC (Nature Aug 2004) -- employing a technique that varied 29
parameters entering into a single model. But an extension of their method
has now dropped these values somewhat to agree with the new IPCC values
[1].
What does it mean if there is consensus among modelers? The assembled
group of IPCC modelers ascribed the narrowing of the range to a "better
understanding of atmospheric processes" [1]. At the same time, however,
Jeffrey Kiehl (NCAR) admits [1] that the models "disagree sharply
about the physical processes." The biggest uncertainty still remains
the magnitude of the cloud feedback. For example, while "the NCAR
and GFDL models might agree about clouds' net effects
they assume
different mixes of cloud properties." The GFDL (NOAA Geophysical
Fluid Dynamics Lab) model shows a three-times greater increase in short-wave
reflection than NCAR. NCAR increases the amount of low-level clouds while
GFDL decreases it. Much of the US gets wetter with NCAR but drier with
GFDL.
The MIT model was not directly compared with others. But some notion
of its validity can be gained from the projected temperature increases
between 1990 and 2100 as a function of latitude - as shown in Fig. 3 [2].
While increases between lat 45 N and lat 45 S are a modest 1 to 2 degC
(depending on whether a certain emission curtailment policy is applied),
the median increase in the polar regions is projected as between 4 and
6 degC -- or up to 0.5 deg per decade. In other words, we should have
seen by now an increase since 1990 of 0.7 degC. But Arctic observations
show a slight cooling trend; the Antarctic shows a strong cooling trend.
We conclude, therefore, that climate models continue to be an unrealistic
exercise -- of moderate usefulness but, absent validation, entirely unsuited
for reliable predictions of future climate change. Alan Robock's (Rutgers)
claim [1] "We have gone from hand-waving to real understanding"
is ludicrous. The claimed convergence of results on climate sensitivity
is nothing more than an illusion. Modelers still are unable to handle
cloud feedback and continue to ignore the even more problematic issue
of water-vapor feedback [3].
They also resist accepting observational evidence [4,5]. A climate sensitivity
of ~3 deg would imply a current temperature trend at the surface of ~0.3
degC per decade and up to double that in the troposphere (acc. to IPCC).
But satellite microwave radiometers and balloon-borne radiosondes agree
on a near-absence of tropospheric warming. These data suggest a climate
sensitivity of perhaps 0.5 degC and certainly not more than 1.0 - only
about 20-30% of the model "consensus." In other words, Global
Warming should not be considered a significant problem.

4. Mixed News About Dioxin
Activists Recruit Church to Carry Dioxin Messages: Cooperating
with activists from Health Care Without Harm, a delegation from the United
Methodist Women (UMW) is urging office supply retailer Staples to promote
chlorine-free paper in its stores and educate store employees on the supposed
dangers of chlorine and dioxin. The United Methodist General Conference
has included an anti-dioxin platform as part of its environmental policy
for the past several years, and supports efforts to promote chlorine-free
paper. A similar campaign targeting Kinko's several years ago brought
about an agreement that all stores stock chlorine-free alternatives at
the same prices as standard white paper. The group continues to target
paper production as a source of dioxin and promote the use of total chlorine-free
bleaching, even though the chlorine dioxide-based processes that now account
for 96 percent of bleached pulp production have virtually eliminated dioxin
from paper-mill wastewater streams
The Dangers of Backyard Burning: Forbes magazine cautioned
readers in its regular Health tip section against burning garbage in open
containers. The magazine warned about the dangers of pollutants from backyard
burning, such as dioxins, volatile organic compounds, and particulate
matter, including trace metals. Forbes noted that backyard burning is
currently the largest known source of dioxin emissions in the United States,
according to EPA.
New Study Finds Lower Background Levels of Dioxins in Animals:
Researchers at Exponent, Inc. have found lower than expected background
levels of dioxins, furans, and PCBs in recent animal studies involving
both rats and pigs. According to Biotech Week, researchers found concentrations
of TCDD and other PCDD/Fs that were several-fold less than concentrations
found in previous studies. The researchers say the lower levels found
in this study may be due to "inadvertent laboratory contamination
in previous studies or to declining levels of PCDD/Fs in laboratory feed,
which parallel overall declines in emissions, general environmental levels,
and human food and tissue levels of PCDD/Fs." The study is published
in the current issue of the Journal of Toxicology and Environmental Health.

5. How Soon Will World Oil Production Peak?
SFS/ 8/19/2004
To Editor, Geotimes
Albert Bartlett (letter, Geotimes July 2004) generously quotes from my
Feb 2004 letter, which questions the Hubbert methodology for predicting
the date of the peak in oil production. As best as I can tell, Bartlett
agrees with my analysis. I therefore only wish to quibble with his "estimated
ultimate recovery" (EUR).
He quotes values of between 200 and 300 billion barrels and derives a
date of 2019 for the peak year of world production. But the BP Statistical
Review gives 1147 bill bbls for PROVEN reserves; the EUR may be several
times larger. Using Bartlett's model, this would put the peak in world
production well beyond the year 2032, i.e., 2019 + (1147-300) x 5.5 days.

6. Pollution Deaths From Smog?
Katherine Hollinsworth
Financial Post, August 09, 2004
Re: Pollution Deaths: Where Are the Bodies?, Terence Corcoran, Aug.
4.
I worked in health care policy research and analysis for a couple of years
and pollution or smog-related deaths was one of my favourite topics to
challenge. I asked if the death certificate was signed "death from
smog," and of course it wasn't. I asked where the deaths occurred
and no one could tell me, but they assumed they happened in hospitals
and nursing homes. I asked for a description of the victim and they told
me they were primarily fragile seniors in hospitals and nursing homes
or asthmatics - they supposed but really couldn't say.
I asked how a day or even a week of smog could kill someone who has been
in an air-conditioned hospital for weeks or months. Since they included
"hospital admissions," I asked what the "normal" number
what be and for what were people admitted on "smog days" - no
such information. I asked for a list of victims, with no identification,
to do a statistical analysis from a given week of high pollution and was
told no one had such a list. How could they have statistics and a report
with no data and no lists?
If pollution actually kills people and at the level claimed, we should
have people dropping dead in the streets or collapsing upon arrival at
the office or at home after being outdoors.
Why don't journalists ask these questions and demand evidence when such
claims are made? Why did it take so long for anyone in the media to challenge
the accepted wisdom on this issue?
I think one reason is the awe with which medical spokespeople are regarded
and the other are reporters who don't know how to read data or to think
logically and analytically. However, this should not preclude others in
the health sector from reviewing such claims and asking for real evidence.

7. Sound Science Loses Stalwart Supporters - And Personal Friends
Philip H. Abelson, whose early research helped lead to
the development of the atomic bomb and the nuclear submarine, and who
later influenced scientific thinking during 23 years as the editor of
Science magazine, died Aug. 1. He was 91 and lived in Washington.
Abelson was a force in science for more than 60 years, beginning in the
1930s, when he was one of the nation's first nuclear physicists. He was
the co-discoverer of the chemical element neptunium and during World War
II worked on the Manhattan Project to develop the atomic bomb. Later,
he was among the first to analyze the bacterium E. coli.
His scientific expertise knew almost no bounds. Trained in chemistry
and physics, he also did groundbreaking research in biology, geology,
biochemistry and engineering. When he was elected to the National Academy
of Sciences in 1959, he could have been admitted in any of seven disciplines.
He chose to be recognized as a geologist.
Abelson published nine books on such varied subjects as microbiology,
energy, food, electronics, health care and earth science - as well as
a collection of his wide-ranging, forcefully written essays that touched
on nearly every field in the vast, expanding world of science. An article
in The Washington Post in 1980 described him as a "nuclear, geo-,
bio-physicist, geo-, paleo-, biochemist, microbiologist and a few other
scientific compound specialties."
In 1944, barely past his 30th birthday, Dr. Abelson was put in charge
of the Naval Research Laboratory in Philadelphia. By March 1946, he had
written a paper detailing how a nuclear reactor could be installed in
a submarine, in effect designing the blueprint for the USS Nautilus, which
was launched in 1955 as the Navy's first nuclear-powered submarine.
In 1987, Dr. Abelson received the National Medal of Science. He belonged
to numerous scientific societies and received dozens of prestigious awards,
including the Kalinga Prize from the United Nations Educational, Scientific
and Cultural Organization and the Distinguished Public Service Award from
National Science Foundation. Affiliated with Carnegie Institution since
1939, he was its president from 1971 to 1978. He received seven honorary
degrees.
When Dr. Abelson became editor of Science in 1962, it had a circulation
of 75,000. By the time he retired at the end of 1984, the circulation
was 155,000.
Personal recollections by Fred Singer
I will really miss Phil, my friend for more than 50 years. I first wrote
to him when he was at NRL and I was still in college, wanting to work
for him. I had read one of his papers.
Phil deserves so much credit - one doesn't know where to start. But we
should remember the fantastic job he did as editor of the AGU journal
J of Geophys Research in the mid-fifties; he single-handedly brought it
back to life.
In the 70s he invited me to write guest editorials for Science and published
many of my Letters. In recent years I would visit him in his Science office
to seek counsel and support. He always gave both - for which I shall always
be grateful.
But I don't see how he could have been opposed to all manned spaceflight
programs, as is often claimed. In 1977 he and Fred Durant joined me in
incorporating the "Ph-D Committee" -- to send a manned expedition
to Phobos and Deimos, the moons of Mars.
==============================================================
Thomas Gold; died June 22 2004, aged 84. He was Professor
Emeritus of Astronomy at Cornell University; founder and for 20 years
director of Cornell Center for Radiophysics and Space Research. . He was
a Fellow, Royal Society (London) and Member, National Academy of Sciences
(US). He never earned a PhD but was awarded Doctor of Science from Cambridge
University and Honorary M.A. from Harvard University.
An obituary in the June 24 Guardian (UK) refers to him as science maverick
who challenged establishment thinking - and quite often turned out to
be right. It continues:
"Tommy" Gold was the initiator, the pragmatist and the persuader
among the trio of young Cambridge scientists who turned cosmology upside
down in the 1950s by proposing their controversial and comforting "steady
state" hypothesis of the universe. This held centre stage for several
years, with Fred Hoyle as its underpinning cosmological philosopher, Hermann
Bondi in mathematical support, and Tommy Gold as its extrovert propagandist.
Gold could leap easily from engineering to physiology, from physiology
to cosmology and on to almost any other speciality. Closed academic cliques
feared him. Throughout his life he would dive into new territory to open
up problems unseen by others - in biophysics, astrophysics, space engineering,
or geophysics.
Controversy followed him everywhere. Possessing profound scientific intuition
and open-minded rigour, he usually ended up challenging the cherished
assumptions of others and, to the discomfiture of the scientific establishment,
often found them wanting. His stature and influence were international.
The "steady state" trio were regarded as mavericks in the 1950s
although, among other things, Bondi later became chief scientific adviser
to the Ministry of Defence. As a group they first worked together on Admiralty
radar research in 1942. Before this, however, Gold had met and befriended
Bondi in the internment camps in Britain and Canada where both had ended
up - with many other highly expert and loyal academic refugees from Hitler
- as "enemy aliens" during the 1940 panic about fifth columnists.
When internment came, Gold was studying engineering at Trinity College
Cambridge, while Bondi was doing mathematics and physics. Both came from
Vienna. Released from internment, he took his degree and, at the request
of Hoyle and Bondi and with (eventual) official approval, joined them
in secret Admiralty research into problems of radar ground clutter. .
Gold emerged from the cold comfort of this extended wartime seminar aware
of a host of new problems in astrophysics and cosmology and much better
equipped to investigate them. It turned out that the electron dynamics
of the magnetron, at the heart of radar, has similarities to the dynamics
of stellar accretion. Hence it related to the theory of matter dispersed
throughout space, to gravitational accretion and to hypotheses put forward
before the war by Hoyle and Raymond Lyttleton. But it was Gold who first
suggested that, whatever the turbulence and violence of galaxies or stellar
systems, the energy balance of the universe would remain stable if matter
were being continuously created and destroyed in equal amounts.
It was many years before this comforting and rather God-like idea succumbed
to the Big Bang, although the steady-state theory was still reverberating
gently in 1980, when Cornell University held a world level symposium in
Gold's honour, the contributions to which were later published as a collective
festschrift.
In the introduction to the book, Professor Edwin Salpeter, who was studying
electrodynamics at Cambridge in the late 1940s, recalls that at this time
Gold had switched from the Cavendish Laboratory to the Medical Research
Council's physiology laboratory, where he was working on a resonance hypothesis
for human hearing.
In the 1950s, Gold switched back to astronomy, becoming chief assistant
at the Royal Greenwich Observatory, where he raised a host of uncomfortable
questions about stellar dynamics and produced a complex mathematical model,
which became known as the "Gold-Hoyle hot universe".
In 1956, he was offered and took the chair of astronomy at Harvard and
never looked back. He made an extraordinary series of contributions across
the spectrum of planetary and astronomical sciences, being swept on to
various US national committees and becoming a much sought-after NASA consultant.
In 1959, he took the directorship of a new centre for radio-physics and
space research at Cornell University, a context within which his extrovert
originality had great freedom and where he remained for the rest of his
life, becoming emeritus in 1981.
One of the most dramatic demonstrations of his genius was the speed and
rigour with which, in 1968-69, he showed that the "pulsars",
just discovered by the radio astronomers Antony Hewish and Jocelyn Bell,
working under Sir Martin Ryle in Cambridge, must contain rotating neutron
stars. This revealed huge new vistas of possibility, for if neutron stars
exist in a galaxy, then, as Dennis Sciama later wrote, it is only a short
step to accepting that black holes also exist. Gold opened the door for
Hawking.
He also generated many controversies. In the 60s, on the run-up to the
manned space programme and a possible lunar landing, there was much confused
debate about the nature of the surface of the moon. Was it hard rock or
was there a deep layer of fine dust? If the moon lander and its astronauts
had to cope with dust layers that were metres thick, then designers needed
to know, and know quickly.
Then, in the late 70s and early 80s, when the world was taking serious
stock of its energy resources, Gold pointed out that some old, deep and
theoretically exhausted gas boreholes were still producing methane at
a low but constant rate. Isotopic dating suggested that a large proportion
of this gas was very old.
Gold suggested that we might be seeing primeval methane, trapped during
the formation of the planet, but continuously rising from the deep interior
of the earth. His calculations suggested that the volume might be prodigious
and hence of extreme importance. Further, this rising gas could be routed
to - and trapped in - major fault structures, and therefore a factor that
could both trigger earthquakes and render them predictable.
These hypotheses, cutting directly across the received wisdoms of narrow
fields of science in which Gold had no recognised expertise, infuriated
some. Small, deep, experimental boreholes, put down in the 80s by the
Swedish government to test Gold's deep gas hypothesis, yielded only a
small volume of gas, but it seemed to be ancient methane and it continues
to flow. Gold later altered his hypothesis to propose a "deep, hot
biosphere" of methane-producing organisms and has been proved resoundingly
right.
Cosmology may be full of eternal question marks, he once said, but life
is here and now. That was Tommy Gold.
Personal recollections by Fred Singer: We first met in
Cambridge in 1950 when he was setting up to study cosmic-ray showers,
a topic of my PhD thesis. From then on we had continuous but infrequent
contact related to planetary physics. I remember a 2-week conference in
Rome when we decided to rent and share an apartment in the suburbs.
His physical intuition was always impressive. In the mid-50s, he correctly
identified the "Sudden Commnecent " of magnetic storms with
a shockwave from the Sun, while I developed the theory of geomagnetically
trapped radiation and magnetic-storm ring currents. Gold coined the term
"magnetosphere."
He proposed original ideas on planetary satellites that we still use
today, but we parted company on the topic of the lunar dust layer. For
a number of years, Gold promoted the idea that a thick layer of dust would
cover many portions of the surface of the Moon. His opinion influenced
the design of the Surveyor lunar landing probes, but their precautions
appeared excessive, as he had overestimated the extent to which electrostatic
fields could move dust particles.
In recent years, Tommy turned out to be a firm proponent of the skeptical
view of Global Warming - providing strong moral support via e-mail. I
last saw him about 20 years ago at a Cornell symposium organized in his
honor by Yervant Terzian. I shall miss him greatly.
=========================================================
J. Gordon Edwards was one of the first to caution that
the DDT bans that followed Rachel Carson's Silent Spring might be doing
the world more harm than good. The 85-year-old entomologist and professor
at San Jose State University passed away last week, as reported by FoxNews.com.
Dr. Edwards offered testimony during 1971 EPA hearings on DDT, and ultimately
secured a ruling from an EPA administrative judge that the regulated use
of DDT did not pose health threats to humans or wildlife. However, his
advice was overruled when EPA decided to ban the chemical. Later, Dr.
Edwards investigated and uncovered connections between Ruckleshaus and
anti-DDT environmental extremist groups and entered into a lengthy legal
battle with The New York Times and the Audubon Society over attempts to
discredit his statements about DDT. In later years, Dr. Edwards continued
to respond to activist attempts to ban many chlorine-containing chemicals,
including writing op-eds defending chlorine from Greenpeace attacks that
appeared in the Chicago Tribune and San Francisco Chronicle.
Personal comment: Had Gordon been successful in opposing
the ban on DDT, millions around the world would not have died needlessly
of malaria and other insect-borne diseases.

8. Words of wisdom
"This seems to be one of the many cases in which the admitted accuracy
of mathematical processes is allowed to throw a wholly inadmissible appearance
of authority over the results obtained by them. Mathematics may be compared
to a mill of exquisite workmanship, which grinds you stuff of any degree
of fineness; but nevertheless, what you get out depends on what you put
in; and as the grandest mill in the world will not extract wheat flour
from peascods, so pages of formulas will not get a definite result out
of loose data."
T. H. Huxley (In a public debate with Lord Kelvin in 1869)
