Why the hell should we (they, in this case) worry about something else that could happen now, or not for hundreds of years? Oh, right, so those same scientists can spend more tax dollars finding the next big problem after that. Like the Supervolcano under Yosemite. Whatever.

I have an idea for a catastrophe. Take half of what we're spending for welfare, and use it to build a SuperFence on the border. Concrete 20' deep and 20' tall, with a depressed center walkway for troops or the border patrol, bunkers built in, and make that sucker 10' thick with a rock/sand fill. The Great Wall of the United States. That'd be a catastrophe for the left AND the illegals...
