Physicists send letter to Senate — Cite 160 scientists protest regarding APS climate position
...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

Regarding the National Policy Statement on Climate Change of the APS Council: 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....
