University of British Columbia Professor published an on-line article that projected an 800m asteroid would hit Antarctica in the fall of 2012.
His article was on the www.phas.ubc.ca website for 2 days before it abruptly disappeared. 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.
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.
It probably was a load of crap.....

One, it was a load of bull.
Two, we really are screwed.

Executive Summary Earth's geological and biological history is punctuated by evidence of repeated and devastating impacts from space. Sixty-five million years ago, an asteroid impact caused the extinction of the dinosaurs along with some 70% of Earth's living species. A more typical recent impact was the 1908 Tunguska Event, a 3-5 megaton explosion which destroyed 2,000 square kilometers of Siberian forest. A future asteroid collision could have disastrous effects on our interconnected human society. The blast, fires, and atmospheric dust produced could cause the collapse of regional agriculture, leading to widespread famine. Ocean impacts like the Eltanin event (2.5 million years ago) produce tsunamis which devastate continental coastlines. Asteroid 99942 Apophis, which has a 1-in-45,000 chance of striking Earth in 2036, would generate a 500-megaton (MT) blast and inflict enormous damage. Devastating impacts are clearly infrequent events compared to a human lifetime: Tunguska, thought to be caused by the impact of a 45-meter-wide asteroid, is an event that occurs on average two or three times every thousand years. However, when Near Earth Object (NEO) impacts occur they can cause terrible destruction, dwarfing that caused by more familiar natural disasters. Advances in observing technology will lead to the detection of over 500,000 NEOs over the next 15 years. Of those several dozen will pose an uncomfortably high risk of striking Earth and inflicting local or regional devastation. The Need for a Global Response Faced with such a threat, we are far from helpless. Astronomers today can detect a high proportion of Near Earth Objects and predict potential collisions with the Earth. Evacuation and mitigation plans can be prepared to cope with an unavoidable impact. For the first time in our planet's 4.5-billion-year history, the technical capacities exist to prevent such cosmic collisions with Earth. The keys to a successful outcome in all cases are preparation, planning, and timely decision-making.

How exactly would they do that? Shoot it, and have pieces raining everywhere? Brilliant suggestion!

Really? Do post a link to the site where you found the asteroid-collision-aversion-defense system details. And no, I didn't bring that idea on myself. I figured that would be your best idea.

Also does anyone remember the big X on the Google earth that someone showed before Elenin passed? Wasn't that about where it was at?
