In late 2009, e-mails from a server at the Climate Research Unit at the University of East Anglia were released that showed some climate scientists in an unfavorable light. Soon this scandal was known as “Climategate” and a highly charged debate started to rage on blogs and in the mass media. Much of the debate has been about the question whether anthropogenic global warming was undermined by the revelations. But ethical issues, too, became part and parcel of the debate. This (...) article aims to contribute to this debate, assessing the e-mail affair in the light of two normative analyses of science, one proposed by Robert Merton, the second by a recent suggestion to use the concept of honest brokering in science policy interactions. On the basis of these analyses, different aspects of malpractice will be discussed and possible solutions will be suggested. (shrink)
