With the United Nations Climate Change Conference in Copenhagen just a few weeks away, leading scientists on the topic probably had a lot of work they would have liked to accomplish this week. That hasn’t been possible, however, thanks to the recent anonymous theft of thousands of emails and documents from the University of East Anglia’s Climatic Research Unit. Instead, key climate-change scientists whose work was involved in the hack have had to spend the past few days defending their research and conducting other forms of damage control.
