    A mantle plume producing almost as much heat as Yellowstone supervolcano appears to be melting part of West Antarctica from beneath. Researchers at NASA have discovered a huge upwelling of hot rock under Marie Byrd Land, which lies between the Ross Ice Shelf and the Ross Sea, is creating vast lakes and rivers under the ice sheet. The presence of a huge mantle plume could explain why the region is so unstable today, and why it collapsed so quickly at the end of the last Ice Age, 11,000 years ago.

    A hole the size of Maine—or larger than the Netherlands, depending on which geographic mass means more to you—has opened up in the Weddell Sea in Antarctica. In an otherwise thick layer of sea ice, still frozen from the Antarctic winter, the hole is an aberration. Ice scientists aren’t sure what’s going on, but they’re all talking about it. “It looks like you just punched a hole in the ice,” atmospheric physicist Kent Moore, of the University of Toronto, told Vice’s Motherboard.

    Al Gore thinks the weather has been out of the Book of Revelation, while Time and ABC News have reported that Antarctica is melting very quickly. Now, itÂ’s not (via NASA):The melt rate of West Antarctica's Thwaites Glacier is an important concern, because this glacier alone is currently responsible for about 1 percent of global sea level rise. A new NASA study finds that Thwaites' ice loss will continue, but not quite as rapidly as previous studies have estimated.The new study, published in the journal Geophysical Research Letters, finds that numerical models used in previous studies have overestimated how rapidly...

    The National Advisor Bureau, headquartered in Masdar City, Abu-Dhabi, plans to source the massive blocks of ice from Heard Island, around 600 miles (1000 kilometres) off the coast of mainland Antarctica. It will then transport them around 5,500 miles (8,800 km) to Fujairah, one of the seven emirates which make up the UAE. One iceberg could provide enough for one million people over five years, according to the company. And the scheme could begin as early as the start of 2018. The firm's director says they have already travelled the transportation route and used simulators to check the feasibility of...

    Since the days of the great early 20th century polar explorers, scientists have noticed the unbelievably bright blue ponds and streams of meltwater that can form on the glaciers and ice shelves of Antarctica and were even crucial to the recent collapse of one ice shelf. While most research into Antarctic ice melt has concentrated on the impacts of warming ocean waters that are eating away at the ice from below, a new continent-wide survey shows that these surface meltwater drainage systems are much more prevalent around the continent than was previously thought. The systems, described in two new studies...

    VOne of the largest colonies of gentoo penguins in Antarctica was decimated by volcanic eruptions several times during the last 7,000 years according to a new study. An international team of researchers, led by British Antarctic Survey (BAS), studied ancient penguin guano and found the colony came close to extinction several times due to ash fall from the nearby Deception Island volcano. Their results are published today (Tuesday 11 April) in Nature Communications. Ardley Island, near the Antarctic Peninsula, is currently home to a population of around 5,000 pairs of gentoo penguins. Using new chemical analyses of penguin guano extracted...

    Scientists believe a massive object that could change our understanding of history is hidden beneath the Antarctic ice. The huge and mysterious “anomaly” is thought to be lurking beneath the frozen wastes of an area called Wilkes Land. The area is 151 miles across and has a minimum depth of about 2,700 feet. Some researchers believe it is the remains of a truly massive asteroid more than twice the size of the Chicxulub space rock that wiped out the dinosaurs. If this explanation is true, it could mean this killer asteroid caused the Permian-Triassic extinction event, which killed 96 percent...
  • THE 'LOST CITY' OF ANTARCTICA

    THERE could be a hidden city frozen underneath Antarctica, according to shock claims. The huge continent is an icy mass, and is currently only inhabited by scientific researchers and penguins thanks to its freezing temperatures. Rumours of a hidden city have been floating about for years, as conspiracy theorists and even some scientists claim the freezing continent is actually the home of the legendary Lost City of Atlantis. One scientific theory claims that once upon a time Antarctica was ice-free and home to an ancient civilisation.

    Sea ice in the Antarctic is much less sensitive to the effects of climate change that that of the Arctic A hundred years of cars, planes, wars, and five billion more polluting people, and there’s nothing to show for it. Old log books kept by Scott and Shackleton show that Antarctic sea ice hasn’t changed much since 1912 reports Joanne Nova. Experts have been concerned that ice at the South Pole had declined significantly since the 1950s, which they feared was driven by man-made climate change. But new analysis suggests that conditions are now virtually identical to when the Terra...

    “It’s generally accepted that it’s no longer a question of whether the West Antarctic Ice Sheet will melt, it’s a question of when,” said Ian Howat, associate professor of earth sciences at Ohio State. “We may see a significant collapse of West Antarctica in our lifetimes.” In 2013, a gigantic rift began forming within a valley in the ice of the Pine Island Glacier. Then, in 2015, a 225-square-mile iceberg broke off and floated away. Discovered a massive crack across the Pine Island Glacier, in the West Antarctic Ice Sheet. Extending for 19 miles, the crack was 260 feet wide...

    New research by an international team shows that the present thinning and retreat of Pine Island Glacier in West Antarctica is part of a climatically forced trend that was triggered in the 1940s. The team — made up of scientists from Lawrence Livermore National Laboratory, the British Antarctic Survey, University of Copenhagen, University of Alaska, Naval Postgraduate School, NASA Goddard Space Flight Center, Lamont-Doherty Earth Observatory of Columbia University, University of Leipzig, University of Geneva and University of Cambridge — analyzed sediment cores recovered beneath the floating Pine Island Glacier ice shelf. The team concluded the date at which the...

    Antarctica has confounded scientists, defying the dire predictions of scientists the South Pole would shrink and exacerbate sea level rise in the coming decades. Climate models predicted Antarctic sea ice would shrink as the world warmed, and that warming would boost snowfall over the southern continent. Neither of those predictions have panned out, and now scientists say “natural variability” is overwhelming human-induced warming. “Truth is, the science is complex, and that in most places and with most events, natural variability still plays a dominant role, and undoubtedly will continue to do so,” Chip Knappenberger, a climate scientist with the libertarian...

    Two small bush planes are flying to the South Pole this week to evacuate workers at the Amundsen-Scott research station — a feat rarely attempted during the middle of the Antarctic winter. Kelly Falkner, the director of polar programs for the National Science Foundation (which runs the South Pole station), said that at least one seasonal employee for contractor Lockheed Martin requires medical treatment not available at the station and needs to be flown out. A second worker may also be rescued. Falkner couldn't provide further details about the medical motivation behind the rescues for privacy reasons. "We try to...

    OSLO (Reuters) - A persistent chill in the ocean off Antarctica that defies the global warming blamed for melting Arctic ice at the other end of the planet is caused by cold waters welling up from the depths after hundreds of years, scientists said on Monday. The Southern Ocean off Antarctica may be among the last places on Earth to feel the impact of man-made climate change, with a lag of centuries to affect waters emerging from up to 5,000 meters (16,000 ft) deep, the U.S. study said. Many people who doubt mainstream scientific findings that human use of fossil...

    In fact, deep ocean circulation slowed down to such an extent that the heavy, saline water mass below a depth of 2000 metres was not in contact with the surface for almost 3000 years. "During this time, so much bound carbon in the form of animal and algae remains trickled down from the more intermixed sea surface into the deep water layer that we were able to identify it as the major carbon reservoir that we have looked for so intensively," says Thomas Ronge. The data also showed that the already old age of the water masses was artificially increased...

    In the new research, researchers took aircraft-based measurements across the vastness of Totten Glacier, and the extremely deep and thick ice canyons behind it — which scientists call “subglacial basins” — in order to understand a critical yet invisible feature: precisely what the layers of rock beneath the ice are really like. This, in turn, provides a clue to the behavior of this region in past warm eras. When marine-based glaciers move back and forth across a seascape repeatedly, they grind against the seafloor and dig up piles of looser sediment, such as sandstone, depositing them in a new location....

    Paris (AFP) - A rapidly melting glacier atop East Antarctica is on track to lift oceans at least two metres, and could soon pass a "tipping point" of no return, researchers said Wednesday. To date, scientists have mostly worried about the Greenland and West Antarctic ice sheets as dangerous drivers of sea level rise. But the new study, following up on earlier work by the same team, has identified a third major threat to hundreds of millions of people living in coastal areas around the world. "I predict that before the end of the century the great global cities of...
