Latest Sea level Stories
A new study analyzing the fluctuations in sea levels during the last time Earth was between ice ages shows that oceans rose some nine feet in only decades due to collapsing ice sheets.
Scientists warn New York City could be at risk to damage from hurricanes and storm surges because they predict global warming could lift sea levels twice as fast as global rates.
Scientists at a Denmark conference say rising sea levels will have a major negative impact on 1-in-10 humans living in the Earth's low-lying coastal areas. Research presented during this week's International Scientific Congress on Climate Change in Copenhagen shows the upper range of sea level rise by 2100 could be in the range of about 1 meter (3 feet) or possibly more.
A German study suggests human water consumption is causing an alarming drop in Dead Sea water levels, with serious environmental consequences. Shahrazad Abu Ghazleh and colleagues at the University of Technology in Darmstadt, Germany, said the lower water levels in the Dead Sea -- the deepest point on Earth -- can impact the area's ability to generate electricity and produce fresh water by desalinization. The researchers said normally the water levels of closed lakes such as the Dead Sea...
A team of Yale geologists has a new perspective on the greenhouse-to-icehouse shift where global climate changed from an ice-free world to one with massive ice sheets in the Antarctic nearly 34 million years ago.
The Greenland and Antarctica ice sheets are melting, but the amounts that will melt and the time it will take are still unknown, according to Richard Alley, Evan Pugh professor of geosciences, Penn State.
Sea levels could rise up to 21 feet in certain regions, according to a new report that takes into account new previously unconsidered factors.
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...
