Low-level aerial surveys aim to understand rapid Antarctic melting Starting this month, a giant NASA DC-8 aircraft loaded with geophysical instruments and scientists will buzz at low level over the coasts of West Antarctica, where ice sheets are collapsing at a pace far beyond what scientists expected a few years ago. The flights, dubbed Operation Ice Bridge, are an effort by NASA in cooperation with university researchers to image what is happening on, and under, the ice, in order to...

The 'Coastland Map' produced by scientists from Durham University and published in the Journal GSA Today, charts the post Ice-Age tilt of the UK and Ireland and current relative sea-level changes. According to the map, the sinking effect in the south could add between 10 and 33 per cent to the projected sea-level rises caused by global warming over the next century. * The projections are less than previous estimations for subsidence and could help local authorities to save money on sea and...

$1.03 million grant from Defense Department program to fund Florida State University study The anticipated sea-level rise associated with climate change, including increased storminess, over the next 100 years and the impact on the nation's low-lying coastal infrastructure is the focus of a new, interdisciplinary study led by geologists at The Florida State University. "Our hypothesis is that the historic storm record, which extends back only about 150 years, isn't a reliable indicator of...

U.S. scientists say a 24-foot-long robotic submarine will be used in a multimillion-dollar, five-year study of melting on the West Antarctic Ice Sheet. Northern Illinois University said its robotic submarine will be lowered through more than a half mile of ice into ocean water in the study that involves nine U.S. institutions. Researchers said the submarine will collapse to a width of only two feet, allowing it to be lowered through a drill hole melted in the ice. The sub is designed to allow...

At an Oxford University climate conference, experts announced that sea levels across the globe will almost inevitably rise more than 6 feet. "The crux of the sea level issue is that it starts very slowly but once it gets going it is practically unstoppable," said Stefan Rahmstorf, a scientist at Germany's Potsdam Institute and a broadly respected sea level expert. "There is no way I can see to stop this rise, even if we have gone to zero emissions." According to Rahmstorf, the best outcome...

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...

The most comprehensive picture of the rapidly thinning glaciers along the coastline of both the Antarctic and Greenland ice sheets has been created using satellite lasers. The findings are an important step forward in the quest to make more accurate predictions for future sea level rise. Reporting this week in the journal Nature researchers from British Antarctic Survey and the University of Bristol describe how analysis of millions of NASA satellite measurements* from both of these vast ice...

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 U.S.-led international scientific team says it has determined that Earth's river deltas are sinking due to human activity, many having recent severe flooding. The researchers, led by University of Colorado-Boulder Professor James Syvitski, found 24 of the world's 33 major deltas are sinking, making them increasingly vulnerable to flooding from rivers and ocean storms and putting tens of millions of people at risk. The study concludes the sinking of deltas from Asia and India to the Americas...

24 of world's 33 major deltas sinking, 85 percent have experienced severe flooding recently A new study led by the University of Colorado at Boulder indicates most of the world's low-lying river deltas are sinking from human activity, making them increasingly vulnerable to flooding from rivers and ocean storms and putting tens of millions of people at risk. While the 2007 Intergovernmental Panel on Climate Change report concluded many river deltas are at risk from sea level rise, the new...

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...
