EGU: Wedsnesday

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”.

    I’d post something intelligent, but I need more coffee … I’m seeing double …

    [Um, sorry about that, now fixed. Network problems -W]

    Iridescent cloud it is.

    ['ello again. Nice to have a real meteorologist onbaord... -W]

    Someone posted this on Lubos’ (not so sceptic anymore?) blog

    Just click on “Q” for the URL from Los Alamos

    [Its probably obsolete - its from 1999. The MSU dataset used then has errors; see RC on the aug 2005 science papers, or read the wikipedia satellite temperature record entry - W]

    Huybers is a busy guy. I assume this is a follow-on from his earlier critique of MBH. His other work on Milankovitch cycle-Pleistocene glaciation timimg (mainly co-authored with Wunsch, but based on Huybers’ ideas as far as I can tell) is impressive considering the ink has hardly had time to dry on his dissertation.

    [This doesn't yet have anything to do with hockey sticks, being before then. But if the same ideas were applied to MWP/LIA type events, it would probably show up the non-synchronicity of some stuff loosely called such nowadays - W]
