Scientists are taking a more in-depth view of how climate change could affect Antarctica's ice, and how even a small change in temperature could lead to a global rise in sea levels. "If you're going to have even a few meters it will change the geography of the planet," Rajendra Pachauri, head of the U.N.'s Intergovernmental Panel on Climate Change (IPCC) told Reuters. "Greenland and Antarctica are two huge bodies of ice sitting on land that could really have very serious implications for the...

According to a study that might help predict rising sea levels linked to climate change, scientists are surprised at how fast coastal ice in Antarctica and Greenland is thinning. Scientists at the British Antarctic Survey (BAS) and Bristol University said that glaciers speeding up when they flowed into the sea caused the biggest loss of ice, which was seen by analysis of missions of NASA satellite laser images. "We were surprised to see such a strong pattern of thinning glaciers across such...

Researchers from the Woods Hole Oceanographic Institution spent last month trying to determine if warmer oceanic waters were seeping into the regions surrounding Greenland. Ruth Curry and a team of researchers based their study on the observation that glaciers have started to flow faster than normal throughout the past decade. This observation led them to believe that warmer, subtropical waters were to blame. In 2005, scientists noticed that Greenland's Helheim Glacier had nearly doubled in...

A new study released on Wednesday showed the Greenland icesheet responded to global warming over the past 10,000 years more quickly than thought, AFP reported. The report suggests that as a result, a medium-sized temperature increase this century could cause the continent-sized ice block to start melting at an alarming rate. The study warns that it is entirely possible that a future temperature increase of a few degrees Celsius in Greenland will result in a icesheet mass loss and contribution...

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...

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...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
