[Paranoid politics almost never achieves its goal. The obvious prejudices, hyperbole, rhetoric, and shrillness gives it away. Name-calling, smearing, and sneering are not arguments.
The idea of a Red Team Exercise–which will tolerate a loyal opposition, a civil debate, a thoughtful discussion, and a well-reasoned dissent—seems like a civilized idea for a civilized society. Steve]
A ‘Red Team’ Exercise Would Strengthen Climate Science
Put the ‘consensus’ to a test, and improve public understanding, through an open, adversarial process.

Tomorrow’s March for Science will draw many thousands in support of evidence-based policy making and against the politicization of science. A concrete step toward those worthy goals would be to convene a “Red Team/Blue Team” process for climate science, one of the most important and contentious issues of our age.
The national-security community pioneered the “Red Team” methodology to test assumptions and analyses, identify risks, and reduce—or at least understand—uncertainties. The process is now considered a best practice in high-consequence situations such as intelligence assessments, spacecraft design and major industrial operations. It is very different and more rigorous than traditional peer review, which is usually confidential and always adjudicated, rather than public and moderated.
The public is largely unaware of the intense debates within climate science. At a recent national laboratory meeting, I observed more than 100 active government and university researchers challenge one another as they strove to separate human impacts from the climate’s natural variability. At issue were not nuances but fundamental aspects of our understanding, such as the apparent—and unexpected—
Summaries of scientific assessments meant to inform decision makers, such as the United Nations’ Summary for Policymakers, largely fail to capture this vibrant and developing science. Consensus statements necessarily conceal judgment calls and debates and so feed the “settled,” “hoax” and “don’t know” memes that plague the political dialogue around climate change. We scientists must better portray not only our certainties but also our uncertainties, and even things we may never know. Not doing so is an advisory malpractice that usurps society’s right to make choices fully informed by risk, economics and values. Moving from oracular consensus statements to an open adversarial process would shine much-needed light on the scientific debates.
Given the importance of climate projections to policy, it is remarkable that they have not been subject to a Red Team exercise. Here’s how it might work: The focus would be a published scientific report meant to inform policy such as the U.N.’s Summary for Policymakers or the U.S. Government’s National Climate Assessment. A Red Team of scientists would write a critique of that document and a Blue Team would rebut that critique. Further exchanges of documents would ensue to the point of diminishing returns. A commission would coordinate and moderate the process and then hold hearings to highlight points of agreement and disagreement, as well as steps that might resolve the latter. The process would unfold in full public view: the initial report, the exchanged documents and the hearings.
A Red/Blue exercise would have many benefits. It would produce a traceable public record that would allow the public and decision makers a better understanding of certainties and uncertainties. It would more firmly establish points of agreement and identify urgent research needs. Most important, it would put science front and center in policy discussions, while publicly demonstrating scientific reasoning and argument. The inherent tension of a professional adversarial process would enhance public interest, offering many opportunities to show laymen how science actually works. (In 2014 I conducted a workshop along these lines for the American Physical Society.)
Congress or the executive branch should convene a climate science Red/Blue exercise as a step toward resolving, or at least illuminating, differing perceptions of climate science. While the Red and Blue Teams should be knowledgeable and avowedly opinionated scientists, the commission should have a balanced membership of prominent individuals with technical credentials, led by co-chairmen who are forceful, knowledgeable and independent of the climate-science community. The Rogers Commission for the Challenger disaster in 1986, the Energy Department’s Huizenga/Ramsey Review of Cold Fusion in 1989, and the National Bioethics Advisory Commission of the late 1990s are models for the kind of fact-based rigor and transparency needed.
The outcome of a Red/Blue exercise for climate science is not preordained, which makes such a process all the more valuable. It could reveal the current consensus as weaker than claimed. Alternatively, the consensus could emerge strengthened if Red Team criticisms were countered effectively. But whatever the outcome, we scientists would have better fulfilled our responsibilities to society, and climate policy discussions would be better informed. For those reasons, all who march to advocate policy making based upon transparent apolitical science should support a climate science Red Team exercise.
