In today’s New York Times Andy Revkin has a follow up story on politics and NASA media policies. The story shows that we are rapidly on our way to intellectual incoherence on this issue. Consider the following:

“The issue is where does science end and policy begin,” said David Goldston, chief of staff to Representative Sherwood Boehlert, chairman of the House Science Committee.

News flash (but not to Prometheus readers!) – There is no line that cleanly divides science from policy. The discussion of the use of the term “climate change” versus the phrase “global warming” clearly shows that there is no getting away from politics in the presentation of scientific issues. As scholars of communication tell us, politics is inherent in the act of communication.

In a more recent example of possible political pressure at the agency, press officers and scientists cited an e-mail message sent last July from NASA’s headquarters to its Jet Propulsion Laboratory in Pasadena, Calif. It said a Web presentation describing the uncontroversial finding that Earth was a “warming planet” could not use the phrase “global warming.” It is “standard practice,” the message went on, to use the phrase “climate change.” NASA officials said the intent was to use the most general term to describe climate fluctuations. But other public affairs workers and some scientists at the agency called it an effort to avoid mentioning that global temperatures are rising. The e-mail message was written by Erica Hupp, a civil servant at headquarters. She did not reply to several requests for comment, but several people who work with her, and others who preceded her in managing earth-science news in the office, said this was a standing unwritten order from political appointees in public affairs. “There was this general understanding that when something in this field was written about that it was to be described as climate change and not global warming,” said Elvia H. Thompson, who recently retired from the same office.

So think about this carefully. The phrase “climate change” was recommended in the Luntz memo as part of a (failed, IMO) strategy to sway public opinion against action on climate change. The phrase “global warming” is preferred by environmental advocacy groups for exactly the same reason. Which phrase do you choose? The choice cannot be determined by science alone. (Though it is worth noting that the science community does indeed prefer the term “climate change”, e.g., it is the IPCC not the IPGW.) As I’ve written here before, even the specific definition of the phrase “climate change” reflects a political position.

Other examples of the use of language as tools of political advocacy in science include the use of the words “fingerprint” (e.g., here) and “harbinger” (e.g., here) as recommended by the Union of Concerned Scientists as means of political advocacy.

Decisions about what press releases are put out and how the content in them is described are always going to be political decisions. There is no scientific basis for deciding what to release or how to frame it. When the Clinton Administration was in office things were spun one way, and when the Bush folks took over things were spun another way. In every case such spinning can be done in a way that does not involve misrepresenting scientific understandings (not that spinners always succeed in this).

There is no line. Looking for one is a wild goose chase. Policies and practices for media relations in science agencies will always be political. And politics is a function of who is in power. If you don’t like it, get involved, run for office, campaign for your favored candidate, get out the vote, participate in special interest advocacy groups, do all of these things. But don’t pretend that science can resolve political disputes. There is no line.
