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:
If there are very deep cuts in emissions, sea level rise would slow between 2050 and 2100. It could then reach by 2100 between 30 cm (1 ft) and 1.0 m (3 + 1 ⁄ 3 ft) from now and approximately 60 cm (2 ft) from the 19th century. With high emissions it would instead accelerate further, and could rise by 50cm (1.6 ft) or even by 1.9 m (6.2 ft ...
Ten percent of the world's population live in coastal areas that are less than 10 metres (33 ft) above sea level. Two thirds of the world's cities with over five million people are located in these low-lying coastal areas. [151] About 600 million people live directly on the coast around the world. [152]
For the first time in human history the majority of people live in urban areas. The United Nations estimates that approximately 68% of the world's population will be living in urban areas by 2050. [3] Urbanization has vast implications including the urban planning, geography, sociology, architecture, economics, and public health of a region. [6]

An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 and 6,000 metres (9,800 and 19,700 ft).Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth's surface.
The World Ocean. For example, the Law of the Sea states that all of the World Ocean is "sea", [8] [9] [10] [b] and this is also common usage for "the sea". Any large body of water with "Sea" in the name, including lakes. River – a narrow strip of water that flows over land from a higher elevation to a lower one
