Peer review in climate change research

Definition

When a scholar completes a research project, he or she is expected to publish the original findings. Before such publication takes place, however, the research undergoes a process known as peer review: Scholars with expertise in the relevant field read prospective articles to evaluate their conformity to the professional standards and conventions of the field. Peer review is employed in all scholarly fields, from the humanities to the sciences, so criteria of evaluation can vary significantly from field to field. For example, scientific papers are expected to present objective, scientifically verifiable data, whereas humanities research is expected to support arguments with evidence but it need not and cannot be purely objective or conform to scientific principles. In some fields, reviewers are strongly encouraged to help authors whose work is deemed acceptable but open to improvement.

While the procedure varies in different journals and fields of study, a journal’s central office generally maintains a file of people willing to review articles and their areas of expertise. An editor selects scholars who are most likely to be knowledgeable in the general area of the proposed publication (peers) and requests their assistance (review). The identity of the article’s author is often known to the reviewer, but the author rarely knows the reviewer’s name. In as short a time as is reasonable (which varies from a few weeks to a year), the editor receives the recommendation concerning publication. The article is designated as acceptable for publication, needing revisions, or recommended for rejection. It is not unusual for an editor to receive conflicting reviews of a manuscript.

Significance for Climate Change

Scientists working strictly in the area of climate change are relatively few, but there is a large number whose work contributes to the debate concerning the reality, magnitude, and causes of global warming. Furthermore, these men and women come from virtually every field of science and engineering. It follows that they read and publish in a wide variety of learned journals. While the public image of science may not emphasize it, each of these groups has somewhat different expectations and procedures with respect to peer review.

The peer review process is of central importance in all scientific work, but it is more sharply focused in studies associated with global warming, because the relationship between science and politics is more apparent in such studies. Generally scientists and politicians function in separate arenas. The chemist, for example, may submit a research proposal to the National Science Foundation, where it is subjected to peer review and funded or rejected. When the research is completed, an article may be written and submitted to the Journal of the American Chemical Society, where it is again subjected to peer review and published or rejected. The new addition to the chemical literature is built upon, modified, or negated by future studies, each of which is peer reviewed.

The politician stands for election on the basis of his or her total record and personality. The review is not by peers, but by constituents. The new legislator works to persuade peers not only that an action is right but also that it is possible and preferable to a number of alternatives. In the debate, the proposal is reviewed by peers; their conclusions and actions are reviewed by constituents in the next election. The legislator may make written arguments in the Congressional Record or the Wall Street Journal, neither of which is peer reviewed.

These activities possess many similarities along with important differences. In the context of global warming, both frames of reference are crucial. Elegant scientific studies are meaningless without effective policies. International agreements based on mediocre science can do more harm than good. It is useful for discussions about the importance of climate change to refer to both the Journal of Climatic Studies and the New York Times, but it is vital that interlocutors distinguish between factual studies and policy debates. It is crucial that both what is probably true and what is possible are addressed, but they must be addressed in different ways using different sources.
