They will be low elevation sites though, and this may be part of the reason. It might be worth seeing if there is anything in the U/A data - but I reckon there won't be much in that region. I've heard Lonnie Thompson talk about the Kilimanjaro core and he got some local temperatures - that we don't have access to, and there was little warming in them. The same situation applies for Quelccaya in Peru and also some of his Tibet sites. Lonnie thinks they are disappearing because of sublimation, but he can't pin anything down. They are going though. Lonnie's email is "Lonnie G. Thompson" You could try emailing Ellen as well both might be in the field. Ellen Mosley-Thompson I'm off much of the next 6 weeks at meetings. I hear you're retiring soon - hope all goes well ! I'm sure you'll still be in the field somewhere. Cheers Phil At 10:32 16/09/2004, you wrote: phil <> we have been concerned that people often use the melting glacier on kilimanjaro as an example of impacts of man-made warming. you may have seen some stories countering this on the sceptics websites. I got philip brohan to look at temps there (see attached) and there isnt any convincing consistent recent warming in the station data. but your gridded CRUtem2V does show a recent warming. presumably that is because (as philip suggests) the gridded stuff has influences from quite a large radius, and hence may reflect warming at stations a long way from kilimanjaro? would you agree that there is no convincing evidence for kilimanjaro glacier melt being due to recent warming (let alone man-made warming)? be grateful for your help cheers geoff Dr Geoff Jenkins Head, Climate Prediction Programme Hadley Centre Met Office FitzRoy Road, EXETER, EX1 3PB, UK tel: +44 (0) 1392 88 6653 mobile: 0787 966 1136 [1]www.hadleycentre.gov.uk Prof. Phil Jones Climatic Research Unit Telephone +44 (0) 1603 592090 School of Environmental Sciences Fax +44 (0) 1603 507784 University of East Anglia Norwich Email p.jones@uea.ac.uk NR4 7TJ UK ----------------------------------------------------------------------------
