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.
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.”
["If APS reviews its statement in light of recent, more accurate research, its council may be inclined to adopt the revised statement on climate change from the open letter. But will APS leaders have the courage to do so in the face of intimidation by political leaders who don?t want to change their policies? It wouldn’t be the first time that political power trumped science."]
