The Silencing of Science

[MountainLaurel]

One of the benefits of writing newspaper articles is that sometimes, instead of sending anonymous insults, readers call you up and tell you interesting things. Two weeks ago, after news broke that a NASA press officer had resigned amid revelations that he'd tried to muffle the agency's top climate scientist, I got several such calls. All were from people with similar tales of government-funded scientists intimidated by heavy-handed public relations departments. Curiosity piqued, I followed one up, at least as far as the nervous scientists and the equally nervous government press officers would let me. Here's what I learned.

The story begins with the publication of an article -- "Potential Environmental Impact of a Hydrogen Economy on the Stratosphere" -- in the June 2003 issue of the journal Science, which is not exactly beach reading. Yet although crammed with graphs, equations and references to chlorofluorocarbons, the basic premise isn't hard to explain: The five authors, all affiliated at the time with the prestigious California Institute of Technology, wanted to explore the potential long-term impact of hydrogen fuel cells on the Earth's atmosphere.

For those who've forgotten, hydrogen fuel cells were, three State of the Unions ago, the thing that was going to save Americans from their oil addiction and stop the auto emissions that help cause global warming. Nowadays switch grass and biomass are the hot alternative fuels, but back in 2003, the president won applause for proposing "$1.2 billion in research funding so that America can lead the world in developing clean, hydrogen-powered automobiles." On Capitol Hill, there were demonstrations of one such "Freedom Car," and the president called on scientists to be "bold and innovative" in their hydrogen research.

Unfortunately for the authors of "Potential Environmental Impact of a Hydrogen Economy on the Stratosphere," their research, while bold and innovative, didn't exactly mesh with the hype. According to their model, tiny leaks from hydrogen cells, if such cells are ever mass-produced, could cause serious environmental damage. But they made no suggestion of inevitability: One of the study's authors, John Eiler of Caltech, pointed out that foreknowledge of potential environmental problems could "help guide investments in technologies to favor designs that minimize leakage." Presumably thinking along the same lines, NASA, which had helped pay for the research, prepared a news release and news conference on the paper.

1. SOTU after next...

For those who've forgotten, hydrogen fuel cells were, three State of the Unions ago, the thing that was going to save Americans from their oil addiction and stop the auto emissions that help cause global warming. Nowadays switch grass and biomass are the hot alternative fuels...

At the SOTU after next, hope and denial will concede another round to reality and we'll be down to burning ox dung for fuel.
