Guardian: The president of the Royal Society, Nobel laureate Paul Nurse, believes that freedom of information laws need to provide for both transparency and protection from harassment, writes Alok Jha for the Guardian. Climate scientists have been targeted by aggressive and organized campaigns of requests for data and other research materials, including unpublished drafts of papers later published in journals—with annotations explaining every change in each successive version of the paper. Complying with one such request is cumbersome. Complying with many of them can prevent much else from getting done, and that appears to have been the intent in some cases. The situation is made more difficult by the relative anonymity of the people filing requests; usually, not much is known about their sources of funding or the context from which they are making the request.
