Report abruptly disappeared: Huge asteroid will hit Antarctica in 2012
May 26, 2012 - The initial data was gathered by The Balloon-borne Large-Aperture Sub millimeter Telescope (BLAST) at McMurdo Station, Antarctica. The theorized asteroid was then tracked by Canada-France-Hawaii Telescope on Mauna Kea, which (with the Adaptive Optics Bonnette) supplies probably the sharpest images currently obtainable from the ground.

One week after this mysterious article disappeared, “Canadian and American astronauts say the world needs to prepare for the big one — the asteroid impact that could one day devastate the Earth.Veteran Canadian astronaut Chris Hadfield is president of the Association of Space Explorers, which has prepared a detailed report on the asteroid threat. The Canadian Space Agency intends to launch NEOSSat next March to look for asteroids that may be hiding near the sun. The $15-million suitcase-sized satellite will circle about 700 kilometers above the Earth. A Canadian Space Agency official says NEOSSat is expected to detect hundreds of new asteroids during its first year of operation. It will also monitor the heavy traffic of satellites now orbiting the Earth to try to prevent possible collisions.” Link
The article hypothesized a 94% probability that the asteroid would impact on the Filchner-Ronne ice shelf and cause 2/3 of ice on Antarctica to crumble into sea. The article surmised the total collapse of all Antarctic ice within 2-4 months after impact. “A deep enough impact would crack the ice shelf like a window and total structural collapse would be inevitable, a few months at the outside.” If the ice on Antarctica was added the the world’s ocean it would raise them by 70 meters.
In January 12 and January 13, 2010, an area of sea ice larger than the state of Rhode Island broke away from the Ronne-Filchner Ice Shelf and shattered into many smaller pieces. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua and Terra satellites captured this event in this series of photo-like images. The ice of the Filchner-Ronne ice shelf can be as thick as 600 m; the water below is about 1400 m deep at the deepest point. The international Filchner-Ronne Ice Shelf Programme (FRISP) was initiated in 1973 to study the glaciological regime of the ice shelf.

• Filchner-Ronne Ice Shelf Under Threat From Climate Change
(CORDIS) - The Filchner-Ronne Ice Shelf, a major Antarctic ice shelf in the Weddell Sea, may start to melt rapidly and cease to act as a barrier for ice streams draining the West Antarctic Ice Sheet. This is the new stark warning from a group of EU-funded climate researchers. Using various model calculations, the team ...
