The release of emails from the Climatic Research Unit at the University of East Anglia at the end of last year provoked a global controversy that is still raging today. Allegations that senior climatologists had manipulated results, fl outed Freedom of Information laws and prevented critics from being published in the academic literature have swept the media and divided opinion among scientists, policy makers and the lay public around the world. Lawsuits about the legality of some of the events surrounding the e-mail affair are pending in the USA. It is possible that more will follow.
