Policy actions that aim to reduce CO2 emissions are unlikely to influence future climate. Policies need to focus on preparation for, and adaptation to, all dangerous climatic events, however caused.

Open Letter to the Secretary-General of the United Nations

Mr. Secretary-General:

On November 9 this year you told the General Assembly: “Extreme weather due to climate change is the new normal … Our challenge remains, clear and urgent: to reduce greenhouse gas emissions, to strengthen adaptation to … even larger climate shocks … and to reach a legally binding climate agreement by 2015 … This should be one of the main lessons of Hurricane Sandy.”

On November 13 you said at Yale: “The science is clear; we should waste no more time on that debate.” Continue reading →

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

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. Continue reading →

Open Letter from scientists, Wall Street Journal

[Open Letter #4: Authors of Open Letter #1 reply to Open Letters #2 and #3.]

The interest generated by our Wall Street Journal op-ed of Jan. 27, “No Need to Panic about Global Warming,” is gratifying but so extensive that we will limit our response to the letter to the editor the Journal published on Feb. 1, 2012 by Kevin Trenberth and 37 other signatories, and to the Feb. 6 letter by Robert Byer, President of the American Physical Society. (We, of course, thank the writers of supportive letters.) Continue reading →

Open Letter #3 from APS President, Wall Street Journal

[This letter also responds to Open Letter #1]

The Jan. 27 op-ed “No Need to Panic About Global Warming” is inaccurate in its characterization of the Climate Change Statement of the American Physical Society (APS), the nation’s leading organization of physicists with more than 50,000 members. Continue reading →

Open Letter #2 from Opposing Scientists, Wall Street Journal

[This letter responds to Open Letter #1 below.]

Do you consult your dentist about your heart condition? In science, as in any area, reputations are based on knowledge and expertise in a field and on published, peer-reviewed work. If you need surgery, you want a highly experienced expert in the field who has done a large number of the proposed operations.

You published “No Need to Panic About Global Warming” (op-ed, Jan. 27) on climate change by the climate-science equivalent of dentists practicing cardiology. While accomplished in their own fields, most of these authors have no expertise in climate science. Continue reading →

Open Letter #1 from Scientists, Wall Street Journal

A candidate for public office in any contemporary democracy may have to consider what, if anything, to do about “global warming.” Candidates should understand that the oft-repeated claim that nearly all scientists demand that something dramatic be done to stop global warming is not true. In fact, a large and growing number of distinguished scientists and engineers do not agree that drastic actions on global warming are needed. Continue reading →
