Glaciation refers to the climatic and geophysical processes leading to the formation, expansion, and persistence of glaciers and ice sheets, and their subsequent sculpting of the Earth’s surface. It encompasses large-scale cooling, snow accumulation exceeding ablation, and dynamic ice flow driven by gravity and basal sliding. Glaciation cycles, governed primarily by orbital forcing (Milankovitch cycles), greenhouse gas concentrations, and feedbacks involving albedo and ocean circulation, produce glacial–interglacial variations in global climate. These events generate diagnostic landforms (e.g., moraines, drumlins, U-shaped valleys) and stratigraphic signatures, and they are central topics in Quaternary science, paleoclimatology, and Earth system modeling.
Buffalo's legendary snowfall totals are largely the result of one unlucky geographic reality: the city sits east of the Great Lakes instead of west. Anyone who has lived through a winter in Buffalo, Cleveland or any snowbelt ...

Imagine your favorite sunny beach. Anywhere will do. You look out and see the ocean stretching to the horizon. To a glaciologist, that view is not just water; it's melted ice. Our new study shows that the best case sea-level ...

Models of glacial flow and retreat rely on estimates of glacial ice viscosity, the measure of the ice's resistance to flow. Ice viscosity is dependent on the stress applied to the glacier. Most ice sheet models use a standard ...
