Regarding the National Policy Statement on Climate Change of the APS
Council:
2 Nov 2009
An Open Letter to the Council of the American Physical Society
"As physicists who are familiar with the science issues, and as current and
past members of the American Physical Society, we the undersigned urge the
Council to revise its current statement* on climate change as follows, so as
to more accurately represent the current state of the science:"
"Greenhouse gas emissions, such as carbon dioxide, methane, and nitrous
oxide, accompany human industrial and agricultural activity. While
substantial concern has been expressed that emissions may cause significant
climate change, measured or reconstructed temperature records indicate that
20th 21st century changes are neither exceptional nor persistent, and the
historical and geological records show many periods warmer than today. In
addition, there is an extensive scientific literature that examines
beneficial effects of increased levels of carbon dioxide for both plants and
animals."
"Studies of a variety of natural processes, including ocean cycles and solar
variability, indicate that they can account for variations in the Earth's
climate on the time scale of decades and centuries. Current climate models
appear insufficiently reliable to properly account for natural and
anthropogenic contributions to past climate change, much less project future
climate."
"The APS supports an objective scientific effort to understand the effects
of all processes - natural and human --on the Earth's climate and the
biosphere's response to climate change, and promotes technological options
for meeting challenges of future climate changes, regardless of cause."

======================================
Open Letter to Senate
A GAGGLE IS NOT A CONSENSUS
You have recently received a letter from the American Association for the
Advancement of Science (AAAS), purporting to convey a "consensus" of the
scientific community that immediate and drastic action is needed to avert a
climatic catastrophe.
We do not seek to make the scientific arguments here (we did that in an
earlier letter, sent a couple of months ago), but simply to note that the
claim of consensus is fake, designed to stampede you into actions that will
cripple our economy, and which you will regret for many years. There is no
consensus, and even if there were, consensus is not the test of scientific
validity. Theories that disagree with the facts are wrong, consensus or no.
We know of no evidence that any of the "leaders" of the scientific community
who signed the letter to you ever asked their memberships for their
opinions, before claiming to represent them on this important matter.
We also note that the American Physical Society (APS, and we are physicists)
did not sign the letter, though the scientific issues at stake are
fundamentally matters of applied physics. You can do physics without
climatology, but you can't do climatology without physics.
The APS is at this moment reviewing its stance on so-called global warming,
having received a petition from its membership to do so. That petition was
signed by 160 distinguished members and fellows of the Society, including
one Nobelist and 12 members of the National Academies. Indeed a score of the
signers are Members and Fellows of the AAAS, none of whom were consulted
before the AAAS letter to you.
Professor Hal Lewis, University of California, Santa Barbara
Professor Fred Singer, University of Virginia
Professor Will Happer, Princeton University
Professor Larry Gould, University of Hartford
Dr. Roger Cohen, retired Manager, Strategic Planning, ExxonMobil

"It is a remarkable fact that despite the worldwide expenditure of perhaps
US$50 billion since 1990, and the efforts of tens of thousands of scientists
worldwide, no human climate signal has yet been detected that is distinct
from natural variation."
Bob Carter, Research Professor of Geology, James Cook University, Townsville |
