On Thursday, 25 March 2010, we had a public discussion organized by the KlimaCampus in Hamburg a discussion about IPCC, Climategate and the relationship of climate science, media and politics - see http://www.klimacampus.de/index.php/News/329/0/?&tx_ttnews[tt_news]=245&tx_ttnews[backPid]=328&cHash=7fc18dbda5.
About 350 people, from academia, authorities, journalists and "people from the street" had shown up. Among them, a person working for the Federal Ministry of the Environment, who was responsible for the process of nominating German scientists for the selection process by the IPCC - to become convening lead authors, lead authors or review authors. She told the audience that all scientists, who volunteered for such a position, had been nominated by the German authorities.
Another interesting detail was an information provided by a person working for the German Weather Service -according to which the German "core data" needed to calculate the global mean temperature curve would be publicly available, whereas other more special data would not.
