Stark headlines reported three studies of huge glaciers flowing into the Amundsen Sea that, if right, could mean a considerable sea-level rise over the next few hundred years.
In the succeeding Quaternary Period (about the past 2.6 million years), there was considerable oscillation of sea level, leading finally to the emergence of a low-lying isthmus that broadened northward to a low-lying open coastal plain.
Scientists and politicians are keen to hold global warming to 1.5C above pre-industrial levels because they fear that a world that warms to such a level will experience severe loss of ice, particularly from Greenland's massive shield of glaciers, and that the melting will in turn trigger considerable rises in sea levels.
Al-Khārijah, the largest of the oases within Al-Wādī al-Jadīd governorate, lies within a depression 112 feet (34 metres) above sea level and has considerable land under cultivation.
The region of southeast Asia surrounding the South China Sea has experienced considerable tectonic activity [ 27], repeated sea level fluctuations [ 28] and associated climatic and vegetation changes [ 29, 30].
The range of elevations within its basin is considerable: from some 14,000 feet (4,300 metres) above sea level in the Colorado Rockies near the Continental Divide to 400 feet (120 metres) where it joins the Mississippi.
Topography has considerable effect on NPP, which peaks near 1350 m above the sea level.
Most of the province lies at or below sea level, consisting of peat in the older parts and clay in the considerable reclaimed areas (polders).
The most intensive slide activity, both in frequencies and volumes, and hence the most considerable landscape modification occurred early in the Holocene period i.e. when the relative sea level fell most rapidly.
What happened in New Orleans epitomizes the risk of living below sea level in a coastal city, depending on structures that were the result of considerable compromise and piecemeal funding and construction.
