“On June 1, 2009, messages with the heading ”China and Climate Change” dropped into the email inboxes of five US State Department officers. The five officers, working in the Office of the Special Envoy for Climate Change, were involved in preparing for delicate bilateral climate change talks in Beijing in several days.
The email appeared to be from a respected economics columnist at a well-known US journal and contained information designed to be of particular and direct relevance to the five staff.”
