West Antarctic Ice Sheet
2014-07-12 06:07:29

redOrbit Staff & Wire Reports - Your Universe Online Much of the climate change-related research published recently has focused on the impact of warming temperatures on the West Antarctic ice sheet – but what is it about this region that causes scientists to be so interested in it? According to the US National Oceanic and Atmospheric Administration (NOAA), the West Antarctic ice sheet contains two major slabs of frozen water (the Ronne and Ross Ice Shelves), as well as several...

New Sea Level Threat Created From Changing Antarctic Winds
2014-07-07 03:55:30

Australian Research Council's Centre of Excellence for Climate System Science New research shows projected changes in the winds circling the Antarctic may accelerate global sea level rise significantly more than previously estimated. Changes to Antarctic winds have already been linked to southern Australia’s drying climate but now it appears they may also have a profound impact on warming ocean temperatures under the ice shelves along the coastline of West and East Antarctic....

redOrbit Staff & Wire Reports - Your Universe Online Newly discovered massive blocks of ice located underneath the ice of Greenland could help scientists learn more about the behavior of ice sheets and how they will respond to global warming, according to research appearing in the latest edition of Nature Geoscience. Lead author Robin Bell, a geophysicist at Columbia University's Lamont-Doherty Earth Observatory, and her colleagues used ice-penetrating radar to discover the ragged...

West Antarctica's Thwaites Glacier Is Melting Due To Geothermal Heat
2014-06-10 10:18:21

Gerard LeBlond for redorbit.com - Your Universe Online Researchers from the Institute for Geophysics at The University of Texas at Austin (UTIG) have discovered that Thwaites Glacier is being eroded by the ocean, as well as being melted from geothermal heat. Their findings are published in the current edition of the Proceedings of the National Academy of Sciences (PNAS). Accurate information from beneath the West Antarctic Ice Sheet has previously been inaccessible, but new findings of...

Antarctic Ice Sheet Became Unstable At The End Of The Last Ice Age
2014-05-29 05:20:26

redOrbit Staff & Wire Reports - Your Universe Online The Antarctic Ice Sheet started melting approximately 5,000 years earlier than previously believed following the last ice age, according to new research appearing in this week’s edition of the journal Nature. The study, which comes in the wake of research suggesting that destabilization of some of the West Antarctic Ice Sheet has already begun, also said that the shrinkage of the ice sheet accelerated and caused rapid sea level...

CryoSat Shows Increase In Antarctica’s Ice Losses
2014-05-19 03:52:32

ESA Three years of observations from ESA’s CryoSat satellite show that the Antarctic ice sheet is now losing 159 billion tonnes of ice each year – twice as much as when it was last surveyed. The polar ice sheets are a major contributor to the rise in global sea levels, and these newly measured losses from Antarctica alone are enough to raise global sea levels by 0.45 mm each year. These latest findings by a team of scientists from the UK’s Centre for Polar Observation and...

Researchers Decipher Climate Paradox From The Miocene Using Complex Model Simulations
2014-04-14 12:34:00

AWI Scientists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), have deciphered a supposed climate paradox from the Miocene era by means of complex model simulations. When the Antarctic ice sheet grew to its present-day size around 14 million years ago, it did not get colder everywhere on the Earth, but there were regions that became warmer. A physical contradiction? No, as AWI experts now found out, the expansion of the ice sheet on the Antarctic...

Pine Island Glacier Retreating
2014-01-14 14:44:51

Lee Rannals for redOrbit.com - Your Universe Online Antarctica’s Pine Island Glacier (PIG) is now in an irreversible retreat, according to a study published in the journal Nature Climate Change. PIG is one of the biggest single contributors to global sea-level rise, and the latest study says that it could add as much as 0.39-inches to ocean levels in 20 years. “Over the past 40 years Pine Island Glacier in West Antarctica has thinned at an accelerating rate, so that at present it is...

Antarctica Holds Subglacial Valley Bigger Than The Grand Canyon
2014-01-14 09:44:05

[ Watch the Video: A Giant Is Lurking Beneath Antarctica's Ice ] Gerard LeBlond for redOrbit.com - Your Universe Online A team of scientists from Newcastle University, the University of Bristol’s Glaciology Centre, the British Antarctic Survey and the universities of Edinburgh, Exeter and York, have discovered a giant trench below the ice in Antarctica. The research team has spent the last three seasons in the West Antarctic region investigating and mapping the area. Recently, they...

Climatic Variability Has A Significant Impact On Pine Island Glacier
2014-01-03 07:31:08

redOrbit Staff & Wire Reports - Your Universe Online Pine Island Glacier, one of the largest routes for ice to flow from Antarctica into the sea, is far more susceptible to climatic and ocean variability than previously believed, according to research published Thursday in the advanced online version of the journal Science. Observations from Dr. Pierre Dutrieux of the British Antarctic Survey (BAS) and his colleagues showed sizable fluctuations in ocean heat in Pine Island Bay. They...

Antarctica
2013-02-18 10:15:24

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...
