Most researchers, Dr. Pielke writes, like to think of themselves in one of two roles: as a pure researcher who remains aloof from messy politics, or an impartial arbiter offering expert answers to politicians’ questions. Either way, they believe their research can point the way to correct public policies, and sometimes it does — when the science is clear and people’s values aren’t in conflict.
But climate change, like most political issues, isn’t so simple. While most scientists agree that anthropogenic global warming is a threat, they’re not certain about its scale or its timing or its precise consequences (like the condition of California’s water supply in 2090). And while most members of the public want to avoid future harm from climate change, they have conflicting values about which sacrifices are worthwhile today.
A scientist can enter the fray by becoming an advocate for certain policies, like limits on carbon emissions or subsidies for wind power. That’s a perfectly legitimate role for scientists, as long as they acknowledge that they’re promoting their own agendas. But too often, Dr. Pielke says, they pose as impartial experts pointing politicians to the only option that makes scientific sense. To bolster their case, they’re prone to exaggerate their expertise (like enumerating the catastrophes that would occur if their policies aren’t adopted), while denigrating their political opponents as “unqualified” or “unscientific.”

Politics in the Lab
Do some scientists have a political ax to grind? Here is an excerpt from another wonderful John Tierney "Findings" article in the Times. Mind the fact that Roger Pielke Jr, the scientist quoted in the article, is a self-described "Obamite."
