A few pics, just in case you think that Vienna is all beauteous; here I choose about the least attractive angle to see the Austria Centre from. . And a maybe irridescent cloud. Not sure. And Richard Alley, from his medal talk. And a slightly nicer view of the conf centre (can you spot it?) from the Donaupark .
Poster: sondes. The Vaisala RS92 produces different answers to the much-used RS80, though mostly above the troposphere. Will this matter? Fans of sondes will read …/RSO-IC-2005_Final_Report.pdf, though apparently this doesn’t include the RS80.
Another poster: was the Younger Dryas global? Huybers says that people up to now ahve done this by peering at wiggles (shades of LIA/MWP) which is prone to subjectiveness; he defines a YD index and tries to do this more robustly.
D+A session is crowded, how odd. Nothing desperately exciting, though.
Chris Jones: carbon cycle models all show +ve feedbacks with GW; though not agreed on exactly how much (about 1/3, from HadCM3, by eye; varies, larger at higher stabalisation levels). This would impact on (reduce) the emissions permissible if we want to be in the “how much emissions can we allow to be likely avoiding X degrees of warming”.
