Global glacier volumes and sea level – effects of ice below the surface of the ocean and of new local lakes on land. Abstract. The potential contribution of glaciers and ice caps to sea level rise is usually calculated by comparing the estimated total ice volume with the surface area of the ocean. Part of this total ice volume, however, does not contribute to sea-level rise, because it is below the surface of the ocean or below the levels of future lakes on land. The present communication points to this so far overlooked phenomenon and provides a first order-of-magnitude estimate. It is shown that the effect is small (most likely 1 to 5 cm sea-level equivalent) but systematic, could primari…

A landmass, or land mass, is a large region or area of land that is in one piece and not noticeably broken up by oceans. The term is often used to refer to lands surrounded by an ocean or sea, such as a continent or a large island. In the field of geology, a landmass is a defined section of continental crust extending above sea level. Continents are often thought of as distinct landmasses and may include any islands that are part of the associated continental shelf. When multiple continents form a single contiguous land connection, the connected continents may be viewed as a single landmass. Earth's largest landmasses are (starting with largest): Afro-Eurasia (main landmass of the geoscheme…

The geography of Antarctica is dominated by its south polar location and, thus, by ice. The Antarctic continent, located in the Earth's Southern Hemisphere, is centered asymmetrically around the South Pole and largely south of the Antarctic Circle. It is washed by the Southern (or Antarctic) Ocean or, depending on definition, the southern Pacific, Atlantic, and Indian Oceans. It has an area of more than 14,200,000 square kilometres or 5,480,000 square miles. Antarctica is the largest ice desert in the world. Some 98% of Antarctica is covered by the Antarctic ice sheet, the world's largest ice sheet and also its largest reservoir of fresh water. Averaging at least 1.6 kilometres or 1 mile th…

This is a list of places on land below mean sea level. Places artificially created such as tunnels, mines, basements, and dug holes, or places under water, or existing temporarily as a result of ebbing of sea tide etc., are not included. Places where seawater and rainwater is pumped away are included. Fully natural places below sea level require a dry climate; otherwise, rain would exceed evaporation and fill the area. All figures are in meters below mean sea level (as locally defined), arranged by depth, lowest first:

Mapping tipping risks from Antarctic ice basins under global warming.. The Antarctic Ice Sheet is subject to amplifying feedbacks which can accelerate ice loss and lead to effectively irreversible retreat. We here analyse the distinct nature and risk of long-term ice loss for each individual drainage basin under different levels of warming. Depending on topographic and climatic conditions, we find that ice loss in some basins unfolds gradually with warming, whereas other basins are characterized by a critical threshold or tipping point beyond which large parts eventually disintegrate. A first threshold, potentially as low as 1-2 °C above pre-industrial levels, triggers the long-term collaps…

Antarctica ( ) is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km2 (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi). Antarctica is, on average, the coldest, driest, and windiest of the continents, and has the highest average elevation. It is mainly a polar desert, with annual precipitation of over 200 mm (8 in) along the coast and far less…
