Gonna wait to see the literal Sun, Moon, and Stars go black, too? Well, look quick, because we would all be solid chunks of ice within a matter of a second, or so, if that was to literally happen... and then we would have nothing further to worry about anyway. All the rest of the book wouldn't matter to us.

What Would Happen If the Sun Went Out?
there is also that something like mega-volcanic eruption (or a large meteor strike, or a combination of the two) throwing enough dust into the atmosphere to effectively blacken the skies is possible, and would not deep-freeze the whole earth 'in a matter of seconds.'
overall i'm with Roger -- will wait and see.
