Image 1 - Warm Ocean Currents Cause Ice Loss In Antarctica
2012-04-26 04:55:01

Lee Rannals for RedOrbit.com [ Watch the Video ] An international team of scientists reported in the journal Nature on Thursday that warm ocean currents are the culprit behind recent ice loss in Antarctica. The team, lead by British Antarctic Survey, used 4.5 million measurements made by a laser instrument mounted on NASA's ICESat satellite to map the changing thickness of Antarctica's floating ice shelves. Of the 54 ice shelves they mapped, they revealed that 20 are melting...

Novel Method To Identify Sources Of Global Sea Level Rise
2012-04-24 11:08:34

As the Earth's climate warms, a melting ice sheet produces a distinct and highly non-uniform pattern of sea-level change, with sea level falling close to the melting ice sheet and rising progressively farther away. The pattern for each ice sheet is unique and is known as its sea level fingerprint. Now, a group of geophysicists from the University of Toronto, Harvard and Rutgers Universities have found a way to identify the sea level fingerprint left by a particular ice sheet, and possibly...

Ice Sheet Collapse And Sea-level Rise At The Bølling Warming 14,600 Years Ago
2012-04-06 04:23:00

International scientists have shown that a dramatic sea-level rise occurred at the onset of the first warm period of the last deglaciation, known as the Bølling warming, approximately 14,600 years ago. This event, referred to as Melt-Water Pulse 1A (MWP-1A), corresponds to a rapid collapse of massive ice sheets 14,600 years ago and resulted in global sea-level rise of ~14 m. These findings are published in the 29 March 2012 issue of the journal Nature (Volume 483, Issue 7391)....

According to a press release from Europe´s Space administration (ESA) part of Antarctica´s ice sheet has increased in height. These findings come from the ESA´s ice-measuring satellite, CryoSat. According to the ESA, these findings not only provide good news from the ice sheets, but also show the effectiveness of their CryoSat missions. According to their website, ESA.int, CryoSat is Europe´s first mission to address the thickness of land and sea ice and how this...

Image 1 - Global Sea Level Could Rise As Much As 70 Feet In The Future
2012-03-21 04:04:57

Scientists looked back in time - in the geologic record - to see the future Even if humankind manages to limit global warming to 2 degrees Celsius (3.6 degrees Fahrenheit)--as the Intergovernmental Panel on Climate Change (IPCC) recommends--future generations will likely have to deal with a completely different world. One with sea levels 40 to 70 feet higher than at present, according to research results published this week in the journal Geology. The scientists, led by Kenneth...

But projections for increase today still loom large The seas are creeping higher as the planet warms. But how high will they go? Projections for the year 2100 range from inches to several feet, or more. The sub-tropical islands of Bermuda and the Bahamas contain important sites where researchers have gone looking for answers; by pinpointing where shorelines stood on cliffs and reefs there during an extremely warm period 400,000 years ago, they hope to narrow the range of global sea-level...

Spectacular Photos Show Birth Of World’s Biggest Iceberg

[ Watch the Video ] Breathtaking images taken from outer-space by NASA's Operation IceBridge -- the largest airborne survey of Earth's polar ice ever flown -- reveal a 19-mile long, 195 ft.-deep crack across a floating ice shelf in Antarctica that could produce the world´s largest iceberg. The rift was first discovered last October, but IceBridge scientists returned soon after to obtain the first-ever detailed airborne measurements of the 310 square mile iceberg calving in...

Climate change effects to be monitored with new fiber-optic distributed temperature sensing Half-mile long thermometers have been dropped through the Ross Ice Shelf in Antarctica that will give the world relevant data on sea and ice temperatures for tracking climate change and its effect on the glacial ice surrounding the continent. The study based at the University of Nevada, Reno is funded by the National Science Foundation's Office of Polar Programs and other NSF grants. "This...

Scientists have created a detailed map called BEDMAP of Antarctica's rock bed that lies underneath its icy surface. The map gives a view of the landscape beneath the ice, and incorporates decades of survey data acquired by planes, satellites, ships and even people on dogsleds. In the map, the highest elevations are marked in red/black, while the light blue color shows the extent of the continental shelf.  The lowest elevations are dark blue, some of which lie below today's seal...

Antarctica is the Earths southernmost continent; it contains the geographic South Pole. It’s situated in the Antarctic area of the Southern Hemisphere, almost completely south of the Antarctic Circle, and is bordered by the Southern Ocean. It’s the fifth-largest continent at 5.4 million sq miles. On average, it is the driest, coldest, and windiest continent as well as having the highest average elevation of all the continents. Considered a desert, the annual precipitation is only 8...
