Civilization as we know it is coming to an end soon. This is not the wacky proclamation of a doomsday cult, apocalypse bible prophecy sect, or conspiracy theory society. Rather, it is the scientific conclusion of the best paid, most widely-respected geologists, physicists, bankers, and investors in the world. These are rational, professional, conservative individuals who are absolutely terrified by a phenomenon known as global "Peak Oil."
Both the United States and the Soviet Union detonated EMP-generating nuclear weapons tests in space during the darkest days of the Cuban Missile Crisis, when the world was already on the brink of nuclear war.
The time that it would take to recover from an EMP attack has generally been estimated to be anywhere from two months to three years. There would almost certainly be a time of great economic hardship. Whether this time of economic hardship is of short or long duration will depend upon the reaction of the American people after the event, and whether any preparation has been made in advance of the event. (So far, such advance preparation has been almost totally absent.)
In widespread power outages of the past in the United States, people have reacted with behavior ranging from rioting and looting (as many did during the July 13, 1977 New York power outage) to patiently waiting for the crisis to be over (as has occurred with some more recent power outages such as the widespread August 14, 2003 outage in the northeastern U.S.). The Power Grid DVD from the History Channel examines the electric power grid with special emphasis on the August 14, 2003 blackout.
If the recovery period were long, and especially if electronic communication were down for a period of months, civilization in the United States could reach a tipping point where recovery would become difficult or impossible.
A nuclear EMP attack could come from many sources. A missile launched from the ocean near the coast of the United States, and capable of delivering a nuclear weapon at least a thousand miles inland toward the central United States, would cause problems that would be devastating for the entire country. A thin-cased 100 kiloton weapon optimized for gamma ray production (or even the relatively-primitive super oralloy bomb of more than 56 years ago) detonated 250 miles above Nebraska, would destroy just about every unprotected electronic device in the continental United States, southern Canada and northern Mexico. Such a weapon would also knock out 70 to 100 percent of the electrical grid in this very large area. Nearly all unprotected electronic communications systems would be knocked out. In the best of circumstances, as completely unprepared for such an event as we are now, reconstruction would take at least two years.
GeoCities (you know, that aging homepage hosting service that you only ever arrived at by accident) is getting ready to shut its doors. The pioneering service, which eventually sold out to Yahoo! and slowly slipped into complete irrelevance, became popular in the 90's during the early dot-com boom for allowing geeks to quickly and easily create their own basic Web sites.
Yahoo ! very quietly announced the demise of the all-but-forgotten service via the GeoCities' help page . GeoCities has stopped signing up new customers (was there anyone actually still signing up for this service?) and, by the end of the year, will shut down entirely. At that point, users' pages will no longer be accessible online.
News of the closing has been greeted with a collective shrug, and a little ironic nostalgia , by the Interwebs. PC World summed it up pretty nicely with the headline: " So Long, GeoCities: We Forgot You Still Existed ." For its part, BetaNews waxed nostalgic over GeoCities's less-than-professional appearance, accurately describing most of the pages on the service as "Eye-searing."
