Fifty 14C dates on dead \nvegetation emerging beneath receding ice margins document \nthe persistence of some of these ice caps since at least \n350 AD.  In situ cosmogenic 14C in rock surfaces, and 14C \nin plant macrofossils from lake-sediment cores demonstrate \nthat the plateau remained ice-free through the middle \nHolocene, but has supported ice caps for more than 2000 \nof the past 2800 years. The rapid disappearance of these \nice caps over the past century, despite decreasing summer \ninsolation, further demonstrates the unusual character of \n20th Century warmth. Widespread ice-cap expansion ~1280 AD \nearly in the Little Ice Age, and intensified expansion \n~1450 AD, coincide with peak stratospheric volcanic aerosol \nloading and reduced solar luminosity, suggesting that these \nmechanisms may have initiated ice-cap growth, subsequently \nmaintained by strong positive feedbacks.
