NASA climate scientist James Hansen has a new paper out, titled “How Can We Avert Dangerous Climate Change,” which is actually a slightly-edited version of his testimony before Congress in April. The paper is available online here (PDF), and it’s worth checking out, of course. But also interesting is the preamble Hansen included in his email announcing the new paper:

President Eisenhower was arguably the last United States President to seek and value advice of scientists. As discussed by John Rigdon in June 2007 Physics Today, scientists played important roles in the World Wars, but they did not have substantial access to and influence upon policymakers. The brief window of influence under Eisenhower was in the wake of Sputnik, being preconditioned by Eisenhower’s tenure as President of Columbia University, where he grew to respect I.I. Rabi. Following Sputnik, Eisenhower established the President’s Science Advisory Committee with Rabi as chairman.

Rigdon describes a conversation of James Killian with Eisenhower in Walter Reed Hospital shortly before Eisenhower’s death, with the former President surrounded by instruments relevant to cardiac care, and his heartbeats visible on an oscilloscope. Eisenhower asked about “my scientists” and said, “You know, Jim, this bunch of scientists was one of the few groups that I encountered in Washington who seemed to be there to help the country and not to help themselves.”

Rigdon is probably right about the lack of substantial influence of scientists on national policymakers today. Congress does not call on the National Academy of Sciences for broad assessment on how to deal with global climate change, nor does the President call on a Science Advisory Committee. Unless the public becomes sufficiently concerned to demand otherwise, it seems that special interests will continue to have undue sway in energy/climate policies.

Grist thanks its sponsors. Become one.

Until community advisory pathways are sought, we can still try to provoke needed discussions in various ways. [my emphasis]
