To better understand what Kilimanjaro and other tropical glaciers are telling us about climate change, one ultimately ought to drive a set of tropical glacier models with GCM simulations conducted with and without anthropogenic forcing (greenhouse gases and sulfate aerosol). (realclimate.org)
It's not the last word, as Gavin notes, but further refinements (which could be higher or lower than 2m by 2100) await more science at both GIS and WAIS, glacier physics, and more comprehensive glacier modeling, which simply requires more time. (realclimate.org)
