Detailed field mapping of moraines in the Sagarmatha (Everest) region of the Nepal Himalayas indicates that there are four stages of glacial advance. The Lobuche stage moraines are fresh and sparsely covered with vegetation, which contact the dirty terminus of glaciers. The Thuklha stage moraines which are covered with soil and vegetation are located just outside of the Lobuche stage moraines. Both the Periche and the Thyangboche stage moraines which show well weathered and vegetation-covered surfaces lie at the valley far down the glaciers. Comparison with Europe and North America suggests that the Lobuche and the Thuklha stages correspond to Neoglacial redavances which culminated a few hundred and also several thousand years ago.The Periche and Thyangboche stages may be of the Late Glacial and the Last Glacial Maximum.The existence of older landforms, considered to be related to glaciers, suggests that the Khumbu region was also glaciated before the Last Inter-Glacial.

“…It was Mercer (1965Mercer ( , 1968Mercer ( , 1970Mercer ( , 1976Mercer ( , 1982 who first studied systematically the Holocene glaciations in Patagonia by dating moraines at several outlet glaciers of the HPS with 14 C and dendrochronology, and proposed a scheme for the Holocene glaciations. By reviewing each article by Mercer, we see how he developed the idea of Neoglaciations in Patagonia.…”

Abstract. It has frequently been suggested that the period encompassing the ninth to the fourteenth centuries A.D. experienced a climate warmer than that prevailing around the turn of the twentieth century. This epoch has become known as the Medieval Warm Period, since it coincides with the Middle Ages in Europe.In this review a number of lines of evidence are considered, (including climatesensitive tree rings, documentary sources, and montane glaciers) in order to evaluate whether it is reasonable to conclude that climate in medieval times was, indeed, warmer than the climate of more recent times. Our review indicates that for some areas of the globe (for example, Scandinavia, China, the Sierra Nevada in California, the Canadian Rockies and Tasmania), temperatures, particularly in summer, appear to have been higher during some parts of this period than those that were to prevail until the most recent decades of the twentieth century. These warmer regional episodes were not strongly synchronous. Evidence from other regions (for example, the Southeast United States, southern Europe along the Mediterranean, and parts of South America) indicates that the climate during that time was little different to that of later times, or that warming, if it occurred, was recorded at a later time than has been assumed. Taken together, the available evidence does not support a global Medieval Warm Period, although more support for such a phenomenon could be drawn from high-elevation records than from low-elevation records. The available data exhibit significant decadal to century scale variability throughout the last millennium. A comparison of 30-year averages for various climate indices places recent decades in a longer term perspective.
