31,487 U.S. Scientists Reject Global Warming Hoax
A growing list of 31,487 U.S. scientists (and counting) has signed a
petition strongly rejecting as unproven the hypothesis of man-made global
warming or climate change. These signers include four NASA astronauts, at
least two Nobel Prize winning physicists, 9,029 Ph.D.s and some of the
nation’s top climatologists. Only U.S. scientists are included in this
particular petition. Only relevant scientific fields are included.

The “Global Warming Petition Project” includes a dramatically strong
statement to which 31,487 scientists have already signed their names:
There is no convincing scientific evidence that human release of carbon
dioxide, methane, or other greenhouse gases is causing or will, in the
foreseeable future, cause catastrophic heating of the Earth’s atmosphere
and disruption of the Earth’s climate. Moreover, there is substantial
scientific evidence that increases in atmospheric carbon dioxide produce
many beneficial effects upon the natural plant and animal environments of
the Earth.
This is very strong statement. A vastly larger number of signers would sign
a less-dramatic, less-controversial petition statement. Other scientists
would only want to say that they remain undecided and are not part of the
fabled “consensus.”
Similarly, most scientists would be discouraged from stating that increased
carbon dioxide is actually beneficial to the climate. Therefore, most
scientists who do not count themselves among the fabled “consensus” would
not go so far as to sign this particular petition.
The petition includes the further statement, which relatively few scientists
would sign on to, even if they reject a consensus on climate change. Most
scientists would prefer to state that they do not know one way or the other:
We urge the United States government to reject the global warming agreement
that was written in Kyoto, Japan in December, 1997, and any other similar
proposals. The proposed limits would harm the environment, hinder the
advance of science and technology, and damage the health and welfare of
mankind.
The project website explains the project as follows:
These scientists are instead convinced that the human-caused global warming
hypothesis is without scientific validity and that government action on the
basis of this hypothesis would unnecessarily and counterproductively damage
both human prosperity and the natural environment of the Earth.
The project website states:
Realizing, from discussions with their scientific colleagues, that this
claimed ‘consensus’ does not exist, a group of scientists initiated the
Petition Project in early 1998.
The project explains:
The purpose of the Petition Project is to demonstrate that the claim of ‘
settled science’ and an overwhelming ‘consensus’ in favor of the
hypothesis of human-caused global warming and consequent climatological
damage is wrong. No such consensus or settled science exists. As indicated
by the petition text and signatory list, a very large number of American
scientists reject this hypothesis.
The project website further explains:
In PhD scientist signers alone, the project already includes 15-times more
scientists than are seriously involved in the United Nations IPCC process.
The very large number of petition signers demonstrates that, if there is a
consensus among American scientists, it is in opposition to the human-caused
global warming hypothesis rather than in favor of it.
The hypothesis of man-made global warming is particularly controversial
because there have never been any empirical experiments testing the effect
of carbon dioxide in the open atmosphere. The hypothesis rests exclusively
on computer models. Models are created by humans and merely reflect the
assumptions and biases of the humans who create them. The only test of such
models is whether they predict accurately future events. However, climate
change models consistently fail to predict real-world temperatures. A real
scientist would reject models that fail that acid test.
Although it is observed in the laboratory that CO2 absorbs and holds heat,
how CO2 behaves in the open atmosphere in a planet-wide climactic system
cannot be tested. One challenge is that atmospheric gases circulate freely.
The air containing minor traces of CO2 can easily soar many miles up to high
altitudes, where the thin air can radiate heat into outer space.

eccentric, the illustration indicates the potential long-term effects on
earth’s temperatures (By NASA, Mysid [Public domain], via Wikimedia Commons)
Another challenge is that researchers must distinguish any effects resulting
from CO2 as opposed to natural climate cycles caused by variations in the
Earth’s orbit around the sun. The Earth’s orbit changes from egg-shaped to
nearly circular and back again due to the gravitational pull of the other
planets. These overlapping Malkinovitch cycles affect the Earth’s climate
over tens of thousands and hundreds of thousands of years, causing periodic
ice ages. The Earth’s temperature has changed over geologic history due to
orbital variations affecting the distance to the sun throughout the year.
Science, of course, was effectively established by the “scientific method”
popularized by Sir Francis Bacon in Bacon’s 1620 book Novum Organum. (
Bacon rejected the thought experiment methods from Aristotle’s Organum,
which today’s post-modern scientists have returned to.) The scientific
method mandates that every hypothesis must be tested and proven by empirical
experiments, and those experiments must be repeated and reproduced by many
independent, unrelated teams of unbiased researchers under varying
conditions in different locations.
Readers may recall “cold fusion.” Researchers at the University of Utah
claimed to have discovered techniques for conducting nuclear fusion—the
immensely-powerful nuclear engine that powers the sun—at room temperatures.
This would have revolutionized human life everywhere. But the Fleischmann–
Pons experiment could not be reproduced by other researchers. Even
convincing scientific experimental results are not valid until replicated by
independent teams.
The petition project was started by Frederick Seitz, Past President of the U
.S. National Academy of Sciences and President Emeritus of Rockefeller
University, and a former director of the atomic energy training program at
Oak Ridge (Tenn.) National Laboratory, and former physics teacher at a
number of top universities (now deceased).
Despite the death of its founder, the project drive is continuing to add
names. However, a limited budget restricts how fast and thoroughly the
petition list can grow.
Moreover, the current totals of 31,487 signers, including 9,029 PhDs, are
limited only by Petition Project resources. With more funds for printing and
postage, these numbers would be much higher.
A 12-page review article about the human-caused global warming hypothesis is
circulated with the petition.
New signatures are being collected by successors here.
