The sea level in Israel has been rising and falling over the past 2,500 years, with a one-meter difference between the highest and lowest levels, most of the time below the present-day level. This has been shown in a new study supervised by Dr. Dorit Sivan, Head of the Department of Maritime Civilizations at the University of Haifa. "Rises and falls in sea level over relatively short periods do not testify to a long-term trend. It is early yet to conclude from the short-term increases in sea...

A major increase in maximum ocean wave heights off the Pacific Northwest in recent decades has forced scientists to re-evaluate how high a "100-year event" might be, and the new findings raise special concerns for flooding, coastal erosion and structural damage. The new assessment concludes that the highest waves may be as much as 46 feet, up from estimates of only 33 feet that were made as recently as 1996, and a 40 percent increase. December and January are the months such waves are most...

In a vivid example of how a small geographic feature can have far-reaching impacts on climate, new research shows that water levels in the Bering Strait helped drive global climate patterns during ice age episodes dating back more than 100,000 years. The international study, led by scientists at the National Center for Atmospheric Research (NCAR), found that the repeated opening and closing of the narrow strait due to fluctuating sea levels affected currents that transported heat and salinity...

Global warming in this century might raise sea levels more than expected in future centuries, says a study that looked at what happened at a time when Neanderthals roamed Europe. Unless global warming is curbed or expensive measures are taken to hold back rising water, the projected sea level rise could submerge about one-third of Florida, southern Manhattan, much of Bangladesh and almost all the Netherlands, for example, researchers said. An expert praised the work but cautioned that such...

Researchers learning more about how water beneath glaciers contributes to ice loss Scientists who study the melting of Greenland's glaciers are discovering that water flowing beneath the ice plays a much more complex role than they previously imagined. Researchers previously thought that meltwater simply lubricated ice against the bedrock, speeding the flow of glaciers out to sea. Now, new studies have revealed that the effect of meltwater on acceleration and ice loss -- through fast-moving...

The World Bank is a vital source of financial and technical assistance to developing countries around the world. At first glance, this may not appear to be connected to space technology, but large development projects and the state of Earth's environment are intrinsically linked. Global climate change is also an increasingly important challenge in overcoming poverty and advancing development in the poorest countries and communities, which will suffer the earliest and the most. These factors...

A U.S. government agency predicted the melting of the polar ice cap in the year 2030. However, climate guru Al Gore said at the U.N. climate conference on Monday that new computer modeling indicates this could happen as soon as 2014. One U.S. government scientist on Monday said the new prediction was too severe, but other researchers have previously projected a quicker end than 2030 to the Arctic summer ice cap. Former U.S. Vice President Gore said, "It is hard to capture the astonishment...

Environmental scientists at the University of Pennsylvania and Durham University have employed a novel combination of geological and model reconstructions of wetland environments during a 10,000-year period to address spatial variations in sea-level history and provide quantitative estimates of subsidence along the east coast of England. The findings indicate that glacial rebound "” the rise or fall of land masses that were depressed by the huge weight of ice sheets during the last...

An international team of environmental scientists led by the University of Pennsylvania has shown that sea-level rise along the Atlantic Coast of the United States was 2 millimeters faster in the 20th century than at any time in the past 4,000 years. Sea-level rise prior to the 20th century is attributed to coastal subsidence. Put simply, land is being lost to subsidence as the earth continues to rise in response to the removal of the huge weight of ice sheets during the last glacial period....

European Environment Agency Kongens Nytorv 6 1050 Copenhagen K, Denmark WASHINGTON, Dec. 7 /PRNewswire-USNewswire/ -- A special day is being set aside during the U.N.-sponsored international climate talks in Copenhagen in December to stress the urgent need to protect the central role of the oceans in the Earth's life support system and address threats faced by coastal communities, especially in developing nations and small island States. Oceans Day, December 14, will highlight the direct...

Current Sea Level Rise
2013-04-01 10:39:21

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...
