Latest Sea level Stories
The European Space Agency's (ESA) ice mission is giving scientists a better look at oceans, coastal areas, inland water bodies and land.
On December 6, NOAA will release a technical report that estimates global mean sea level rise over the next century based on a comprehensive synthesis of existing scientific literature.
In a new study that ends 20 years of uncertainty, an international team of satellite experts have produced the most accurate assessment of ice losses from Antarctica and Greenland to date.
An enhanced approach to capturing changes on the Earth's surface via satellite could provide a more accurate account of how ice sheets, river basins and other geographic areas are changing as a result of natural and human factors.
Since 1900 the global sea level has risen by approximately 20 cm. Melting glaciers are one of the causes – along with warming and thereby expanding sea water, melting Greenland and Antarctic ice sheets, and changing terrestrial water storage in dammed lakes and groundwater reservoirs.
Utilizing satellite data, a team was able to more accurately calculate the ice sheet mass loss by mapping and removing the mass changes caused by the flow of rock beneath the Earth’s surface.

Glaciers are one of the largest reservoirs of freshwater on our planet, and their melting or growing is one of the best indicators of climate change.
The summer melting season in Greenland usually lasts from June when the first puddles of meltwater appear, to September when temperatures begin to cool again.
The cause of rapid sea level rise in the past has been found by scientists at the University of Bristol using climate and ice sheet models.
The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...
A radar altimeter measures altitude above the terrain beneath an aircraft as opposed to a barometric altimeter which provides the distance above a pre-determined datum, usually sea level. Radar is the underpinning principle of the system. Radio waves that are reflected back from the ground are timed in order to calculate speed, distance, and time which are related to the each other and can be used to calculate the distance from one point to another. Lloyd Espenschied invented the radar...
