Evidence from glacial advance / retreat (e.g. the evidence from tropical Andean glaciers you cite above) is often difficult to interpret, because glacial mass balance represents in general a subtle competition between the influences of ablation (determined by changes in temperature thresholds reached) and accumulation (determined by changes in humidity and precipitation).

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)
