The relative timing of late Quaternary glacial advances in mid-latitude (40–55 S) mountain belts of the Southern Hemisphere (SH) has become a critical focus in the debate on global climate teleconnections. On the basis of glacial data from New Zealand (NZ) and southern South America it has been argued that interhemispheric synchrony or asynchrony of Quaternary glacial events is due to Northern ...

Glacial lake outburst flood (GLOF) is a serious hazard in high, mountainous regions. In the Himalayas, catastrophic risks of GLOFs have increased in recent years because most Himalayan glaciers have experienced remarkable downwasting under a warming climate. However, current knowledge about the distribution and recent changes in glacial lakes within the central Himalaya mountain range is still ...

[1] A physical mechanism is proposed for the glacial-interglacial variations in the rate of vertical mixing and in sea ice cover in the Southern Ocean. Such variations were postulated without an explanation by Toggweiler [1999] and Stephens and Keeling [2000], who used them to explain the glacial-interglacial CO2 variations. In the physical mechanism explored here, initially given by Gildor and...

Over the past few decades, glaciers worldwide have been retreating, resulting in changes in water resources with direct socio-environmental impacts. The flow of glaciers is intrinsically linked to the morphology and dynamics of sub-glacial water. However, these sub-glacial processes remain largely mysterious, and current techniques of modeling the glacial flow based on these sub-glacial structu...

the main issues about relation between climate and relief in the romanian geomorphological literature follow three directions of research: the description of pleistocene glacial and pleistocene-holocene periglacial landforms in the carpathians; the direct analysis of climate?s role in landform development; the integration of separate works and findings in a synthetic morphodynamic system applic...

the altitude to which the past glaciers had been extended during the last glacial period in dinevar basin, western iran, can be estimated based on glacier-geomorpic evidence such as cirques, u-shaped valleys, and the moraines in lowlands. this study estimates the elevation of snowline during this period for the basin as the objective of the research. topographic and geologic maps, landsat image...

The morphology of the western Alps has been strongly influenced by Quaternary glaciations. On the basis of observations of glacial morphology in the Belledonne, Grandes-Rousses, Taillefer and Pelvoux-Ecrins Massifs (south-eastern France), we reconstitute the glacial trimline and equilibrium line altitude (ELA) during the most extensive glaciation (MEG). Our best estimate of the MEG ELA is 1800±...

[1] Climate change indirectly alters the distribution of tectonic uplift at active orogens by modifying the action of surface processes, which in turn alters mountain topography. The impact of alpine glaciation on tectonic activity is explored here. The predictions of previous analytical, critical wedge models are compared with the output of a numerical model that explicitly couples rock uplift...

Supra-glacial lakes (i.e., ponds of melting water on ice sheet) in Greenland have attracted extensive global attention during the recent years. To understand the important role they play in glacier movement, sea level rise, and climate change, scientists need to learn where these lakes are, when they form, and how they change in each melting season and across multiple years. This requires detec...
