    Paris (AFP) - Sea levels around Antarctica have been rising a third faster than the global average, a clear sign of high meltwater runoff from the continent's icesheet, scientists said on Sunday. Satellite data from 1992 to 2011 found the sea surface around Antarctica's coast rose by around eight centimetres (3.2 inches) in total compared to a rise of six cm for the average of the world's oceans, they said. The local increase is accompanied by a fall in salinity at the sea surface, as detected by research ships. These dramatic changes can only be explained by an influx of...
  • Rise of Oceans Due to Melting Antarctic Ice Sheet Is 'Unstoppable'

    Two forthcoming reports on the western Antarctic ice sheet confirm previous fears that the ice's melt will increase ocean levels by as much as 13 feet within the next few centuries. They also suggest that the process has already begun and is likely not reversible. The New York Times reports that both papers one by NASA scientists, to be published in Geophysical Research Letters, and one by University of Washington scientists to appear in Science find that the West Antarctic ice sheet is melting because of naturally-occurring warm water welling up from deep in the ocean. None...

    Junk Science: Researchers have discovered a chain of smoldering active volcanoes under the West Antarctic ice sheet which happens to be the ice sheet that climate hysterics say is proof of man-caused global warming. The 2004 science fiction movie "The Day After Tomorrow" and the operative word here is "fiction" opened with a portion of the West Antarctic ice sheet shearing off as a prelude to planetary doom. But if the researchers depicted in the film had looked deep into the widening crevice, they might have noticed a string of active volcanoes lurking under nearly a mile...
  • N. Korea's largest port frozen for 2 straight winters (huge ice sheet along Yellow Sea coast)

    N. Korea's largest port frozen for 2 straight winters SEOUL, Feb. 10 (Yonhap) -- North Korea's largest port of Nampo has frozen for the second winter in a row due to a severe cold spell, an environmental research institute said Friday. The trade port, the marine gateway of the country's capital Pyongyang, is believed to have been frozen since Jan. 6, according to the Korea Center for Atmospheric Environment Research, citing satellite images. Chung Yong-seung, head of the research institute, said it is rare for the port to freeze two winters in a row, a development he said could have...

    Junk Science: The EPA may be considering closing the watchdog office that exposed the flimsy evidence of man-caused warming. So much for the administration's promise to "restore science to its rightful place."Recently we commented on the plight of Dr. Allen Carlin, the EPA senior research analyst at the National Center for Environmental Economics who dared to say, in essence, that emperor Al Gore and his environmental sycophants at the Environmental Protection Agency wore no clothes. The EPA had been working on an "endangerment finding" that would say carbon dioxide, rather than being the basis for all life on earth, was...

    Climate Change: A suppressed EPA study says old U.N. data ignore the decline in global temperatures and other inconvenient truths. Was the report kept under wraps to influence the vote on the cap-and-trade bill? This was supposed to be the most transparent administration ever. Yet as the House of Representatives prepared to vote on the Waxman-Markey bill, the largest tax increase in U.S. history on 100% of Americans, an attempt was made to suppress a study shredding supporters' arguments.

    PARIS (AFP) - A powerful volcano erupted under the icesheet of West Antarctica around 2,000 years ago and it might still be active today, a finding that prompts questions about ice loss from the white continent, British scientists report on Sunday. The explosive event -- rated "severe" to "cataclysmic" on an international scale of volcanic force -- punched a massive breach in the icesheet and spat out a plume some 12,000 metres (eight miles) into the sky, they calculate. Most of Antarctica is seismically stable. But its western part lies on a rift in Earth's crust that gives rise to...

    Source: University of Copenhagen Date: July 5, 2007 Fossil DNA Proves Greenland Once Had Lush Forests; Ice Sheet Is Surprisingly Stable Science Daily Ancient Greenland was green. New Danish research has shown that it was covered in conifer forest and, like southern Sweden today, had a relatively mild climate. Eske Willerslev, a professor at Copenhagen University, has analysed the world's oldest DNA, preserved under the kilometre-thick icecap. The DNA is likely close to half a million years old, and the research is painting a picture which is overturning all previous assumptions about biological life and the climate in Greenland....

    WELLINGTON, New Zealand - An ice sheet in Antarctica that is the world's largest with enough water to raise global sea levels by 200 feet is relatively stable and poses no immediate threat, according to new research. While studies of the Greenland and West Antarctic ice sheets show they are both at risk from global warming, the East Antarctic ice sheet will "need quite a bit of warming" to be affected, Andrew Mackintosh, a senior lecturer at Victoria University, said Wednesday. The air over the East Antarctic ice sheet, an ice mass more than 1,875 miles across and...

    Ice sheet complexity leaves sea level rise uncertain 13:41 16 March 2007 NewScientist.com news service Catherine Brahic Ice shed from the giant sheets covering Antarctica and Greenland is responsible for just 12% of the current rate of global sea level rise, according to a new review. The authors emphasise that it is now clear that the ice caps are losing ice faster than it is being replenished by snowfall. But exactly why this is happening remains unknown, making it difficult to predict the extent of future sea level rises. The remaining 88% of the current rise is due to the...

    LONDON (Reuters) - Greenland's huge ice sheet could melt within the next 1,000 years and swamp low-lying areas around the globe if emissions of carbon dioxide (CO2) and global warming are not reduced, scientists said on Wednesday. A meltdown of the massive ice sheet, which is more than three km (1.8 miles) thick would raise sea levels by an average seven meters (yards), threatening countries such as Bangladesh, island in the Pacific and parts of Florida. "Any area that is less than seven meters above sea level would be flooded," said Jonathan Gregory, a climate scientist at the University of...
