In case you missed it: Phil Jones on Kilimanjaro glaciers: "Lonnie [Thompson] thinks they are disappearing because of sublimation"

Email 5315

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" [Phil Jones]

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
