Scientists are trying to determine what occurred in Greenland's history to cause its glaciers to rapidly melt, and what implications it might have for the earth's future in light of looming global warming. In 2005, scientists noticed that Greenland's Helheim Glacier had nearly doubled in speed as it moved through a river at a pace of 100 feet per day. The rapid movement caught researchers by surprise and sparked concerns that it could be a sign of a massive melting of the Greenland's ice...

U.S. scientists say persistent winds and a weakened current contributed to higher than normal June and July sea levels along the Eastern Seaboard. A National Oceanic and Atmospheric Administration report says water levels six inches to two feet higher than originally predicted were reported. NOAA scientists analyzing data from select tide stations and buoys from Maine to Florida said they found a weakening of the Florida Current Transport -- an oceanic current that feeds into the Gulf Stream...

Persistent winds and a weakened current in the Mid-Atlantic contributed to higher than normal sea levels along the Eastern Seaboard in June and July, according to a new NOAA technical report. After observing water levels six inches to two feet higher than originally predicted, NOAA scientists began analyzing data from select tide stations and buoys from Maine to Florida and found that a weakening of the Florida Current Transport"”an oceanic current that feeds into the Gulf...

An international team of scientists, led by Denmark, says it set a single-season deep ice core drilling record this summer in Greenland. The researchers, with the University of Colorado at Boulder as the lead U.S. institution, recovered more than a mile of ice core that is expected to help scientists better assess the risks of abrupt climate change in the future. The project, known as the North Greenland Eemian Ice Drilling, is being undertaken by 14 nations led by the University of...

The conference showed that the Arctic climate is changing rapidly in a number of different ways: The recent rate of decrease in thickness and volume of the Arctic sea ice has been faster than the rate of aerial shrinkage determined from satellites. Given that the present trend of melt continues, some models indicate that it is quite likely that the Arctic Ocean could be ice free in the summer time as early as 2015-16. There has been a rapid increase in the mass-loss from the Greenland ice...

 Researchers have largely put to rest a long debate on the underlying mechanism that has caused periodic ice ages on Earth for the past 2.5 million years "“ they are ultimately linked to slight shifts in solar radiation caused by predictable changes in Earth's rotation and axis.In a publication to be released Friday in the journal Science, researchers from Oregon State University and other institutions conclude that the known wobbles in Earth's rotation caused global ice levels to...

The world's glaciers are indeed melting, but a monumental study released Thursday in the journal Science discovered that it might not happen as quickly as once thought. The study notes that there are more gradual shifts in the current systems in the North Atlantic Ocean, instead of a rapid meltdown that could cause swift climate changes to Europe and other places. The research, based on a "general circulation model" that replicated the Earth's climate 21,000 years at the height of the last...

The Greenland ice sheet is melting faster than expected according to a new study led by a University of Alaska Fairbanks researcher and published in the journal Hydrological Processes. Study results indicate that the ice sheet may be responsible for nearly 25 percent of global sea rise in the past 13 years. The study also shows that seas now are rising by more than 3 millimeters a year--more than 50 percent faster than the average for the 20th century. UAF researcher Sebastian H. Mernild and...

New research by scientists in Britain and China reveals evidence of how the East Antarctic ice sheet initially formed. The work provides a snapshot of terrain that has lain hidden miles beneath the ice for millions of years, when rivers ran through mountain valleys that were oddly similar to the modern European Alps. The scientists used radar to map an area of the Gamburtsev mountains, believed to be where the ice originated. The region would have been cold enough to support the...

"Anybody who observes waves can see that they are not the same height in winter and summer, but rather that their height varies over time, and we have applied a 'non- seasonal' statistical model in order to measure extreme events such as these", Fernando J. M©ndez, an engineer at the Institute of Environmental Hydraulics at the University of Cantabria and co-author of a study published recently in the journal Coastal Engineering, tells SINC. The new model can chart the pattern of extreme...

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...

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...
